720p showoff video

Yeah i know its a demo video that comes with omnia hd's.
But it works perfectly on our hd2's.
Nice video to show to your friends

YAY! Thanks a lot for this. I have seen this running on an Omnia Pro and it looked really cool. It really might be a great demo video to look at on the HD2.
One thing though: This is no 720p video. It's only 360p and it even gets upscaled on the HD2. If there would be problems playing such a small resolution source on the HD2 I would seriously doubt HTC until the end of all times.

I ran a benchmark test using a topaz with Leo rom Tess 3.9 + 2.5 sense,
video/audio information (according to VLC on laptop):
640*360, 30 FPS, mp4v
mp4a 44100 Hz
best playback in order
1. coreplayer (default settings, installed to internal memory)
2. wm player
3. htc album
coreplayer benchmark results;
avg speed: 77.10%
vid frames: 2995
audio samplle: 4393489
amount of data: 47521 kb
bench............- .................. original:
time: 02:09.487 ............... 01.39.833
frame rate: 23.130 ........... 30.000
sample rate: 33929........... 44100
data rate: 3.01 Mbit/s .......3.90 Mbit/s
conclusion: rather better sound with stuttering video than no stuttering video but stuttering sound (when CP ran test)
hope you enjoyed this little test, and lets see what the big league has to say about how it's supposed to run

on Toshiba TG01:
Average Speed: 194.17%
Benchmark Data Rate: 7.57 Mbit/s
Original Data Rate: 3.90 Mbit/s

^so Toshiba is 2-3 times as quick as HD2? lol

No its 2-3 times faster than a topaz running a leo ROM, which is to be expected.

I am downloading some movies right now in Mp4 format HD quality, 1280x720, i want to see how it looks on the HD2.
I dont think it should be a problem for this thing to play a 1.4 gb file, right?
BTW the Helicopter movie looks great on this beauty

Good luck , first of all i could not play those files.
Even coreplayer does not play anything bigger then 1008 pixels (program limit)
And second , it doesnt really make sense to play a higher resolution then the display can handle.

okay
what do you recommend?
i couldn't find a lower resolution.
convertion? with?

oh...ok thanks a lot for clarification.
I should have kept reading carefully.

No, but as some have mentioned -it would be nice if the HD2 COULD play higher resolutions as you wouldn't have to convert before transfering to the phone. I myself don't have so much of a problem with doing a conversion -but I can see the wish for just transfering what ever files you already have -and they'll be able to play..

First one works best for me. I get some weird artifacts on the other converter. Don't know why..

thnx
gonna give it a try,
thanks a lot
watching movies on this thing in the car would be nice i think
i convert it, i try it, i watch it, i like it.
picture and sound on this beauty, is a beauty
thnx niknik76

thanks for the video however doesn't play well on my coreplayer. i played on win media looks great. on my other phone(vibrant) looks sick.

thanks for the vid, looking forward to trying this, i've not seen a movie on my phone yet......

Encoding MKV Files for Playback

Hello Everyone,
After much testing/researching, I have finally found the best solution to encode .MKV files to .MP4 for flawless playback on the HD2 using MediaCoder. I have tried many of the other methods and settings provided by others on this forum and many of them were good, but simply took too long or sometimes caused choppy playback on the HD2.
Note: These settings will work for any video files, I just happen to use .MKV for their quality.
MediaCoder Settings:
Format: H.264
Mode: Average bitrate @ 1200Kbps
x264 Profile: Baseline
Audio encoder: FAAC
Audio Format: LC-AAC
Audio mode: Average bitrate @128Kbps
Container: MP4
Resize: 800x450
Aspect ratio: Set PAR 1:1
With these settings I have tested 12 different files ranging from 500MB-1.8GB in size(720p quality) and the largest took 34 minutes on my dual core CPU (intel i5). First tried playing the files with HTC Album player and CorePlayer and the results weren't very good and they included a lot of choppiness. After reading some others success with WMP, I decided to give it a shot and I was pleasantly surprised to find that it played the .MP4 files beautifully and without a single hiccup.
Some of you may already have solutions for encoding videos for playback on the HD2, but I have found these settings to be perfect for anyone who wants to encode HD .MKV files.
I want to thank everyone who has contributed to finding the best method of converting/encoding files for playback, but I can honestly say these settings will give you amazing quality and smooth playback, even in the most intense action scenes. Give it a try!

Thank you very much as this was one of my next endeavors to work on and you just saved me tons of time!

Not a problem, I honestly spent hours upon hours encoding with different settings and players to get it to run smoothly. One thing I haven't tried though is encoding 1080p files. If you do, let me know how they run!

Sure will - I have very few 1080 files to try right now (may be 1 or 2).

+1
Someone should sticky this, perfect playback on my HD2 with these settings!

Thank you so much.

Just saved me a ton of time figuring this out. Used for a couple of videos and they play great. Thanks

The only change I made is resizing to 800x480. Flawless playback.

Tried these settings and although they were good, took about an hour to encode, longer than the length of the video in the first place. The settings I posted are to encode video files quicker, and with MediaCoder and not TMPGEnc.XPress.
Different settings, different program

Those bit-rates seem awfully low to me, especially if you're not using CABAC. Do you not get better results with bit-rates >2000kb/s?

There's also a different thread for video encoders, but too lazy to look it up. Guess it's better to have a new thread every now and then instead of having 50 new "How do I get my HD2 to play videos smoothly?" threads show up every other week.
My encodes take about 5-10minutes tops. Only when doing a 2 pass encode does it take longer and there's really no point in doing those anymore unless you aim for a specific file size.

No point in going beyond 2000Kbps as you won't see the difference and the files becomes too big.
Using a crf value of 21 usually results in a bitrate of around 1000-1500kbps.

What exact settings are you using to encode files in 5-10 minutes? Also, what are the file sizes? I am all for learning new ways to do things, I would love to be able to encode in that short amount of time. Let me know!

Depends on the source and of course encoding settings. I usually do a basic [email protected] Encode with --crf 23 and --ref 1(no weighted B-frames and no I-frames) for TV shows and [email protected] --crf 21 --ref 2 for movies. I also use lanczos4 to downscale to 800 x XXX.
Encoding also relies pretty heavily on the hardware involved so the better the hardware the faster the encoding speed. Currently running my i7 at 4Ghz and cpu utilization is 100%(for all eight threads). The software also makes quite a difference and I noticed that MeGui was the fastest encoder of the ones I tried(and it's pretty easy to use).

Sure thing i'll try that out. I'm running an i5 at 2.2 GHz and many of the other encoding methods took ages to run at 100% CPU usage (2 pass). Thanks for the info, I love learning new and more efficient ways of doing things!

2 pass and constant quality use the same algorithm so the quality is exactly the same.

How do I get .avi files to play in my HD2

Acceptable Video Playback

Hy guys, I tryed several times to make a video format that runs with great quality and at the same time fast enough to watch it with joy.
I have the Titanium ENERGY ROM that came out on may 1.
TCPMP was allready in the ROM
installed the CorePlayer v1.3.6 Build-7427 for PPC
and using the WinMedia Player that also was in the ROM
have on the PC the Xilisoft Video Converter Ultimate, HTC Encoder, the Any Video Converter and the MP4 for HD programs.
the only succesfully smooth video playback was the KillBill named movie that's properties are in the Core Player :
Format : Video Files (AVI, DIVX, GVI)
Duration : 1:46:10.800
Filesize : 595333 KB
Video : MPEG4 Video
Codec : Core ASP
Video Size : 640x272
Frame Rate : 25.000
Audio : MPEG Layer-3
Codec : CoreMP3
Audio Format : 48000 Hz 2 Ch
Data Bit Rate : 83 kbit\s
Played Frames : 18
Dropped : 0
Played FPS : 25.000
this is the only video that runs so perfectly that's almost too good to be true.
so the problem is that i can't find the good settings for any of the converters to give the output vide that' the same as that MAGICAL ONE.
If someone have an idea, please tell !!!!!
THX anyway.

[Q] Video - got conversions right but new problem

So I must admit, from a video playback issue, I've never owned a more frustrating device. That being said, because I love everything else about the XOOM, I've been willing to work to achieve good results. I have achieved great video quality with encoding times similar to what I saw when targeting my iPad, and file sizes that are totally manageable. I have attached the Handbrake profile I'm using. I hope everyone achieves similarly satisfying results. I am using Rockplayer.
OK, on to my new problem. Whenever I adjust the volume and it brings up the volume slider, the video slows though the audio continues, dropping the video out of sync. I have to jump ahead or back to bring the video back into sync. It is similar to the lag in video playback that happens when I first launch the video, but in this case, the playback corrects itself within seconds. Can anyone help with this issue?
I've messed with my XOOM like crazy since getting it, constantly installing and uninstalling applications and files. Could this be an issue?
Thanks in advance for your help!

While using RockPlayer are you using software or hardware decoding? Go to settings, scroll to the bottom and see if hardware decoding mode is checked. If not then check it, but please note you will have to uncheck the box when you want to decode non converted formats like Divx, Xvid, and MKV.
P.S. If all of your video files are properly converted H.264 videos with .mp4 containers you should be able to use use the gallery application to play all your videos, and if you don't like the gallery application for videos you can just use a file manager like astro or IO to select the videos from their folder and play them with the built in video player.

I personally use Total video converter & I have no problems with my video or audio.handbrake just wasn't what I was looking for.total video converter works flawlessly.

Some people have reported similar issues when using HB for various Droid models.
Personally I use the build-in Gallery for video playback, because it makes use of the hardware acceleration.
If you are interested, I have a few samples of 720p and 1080p video files on my website that play perfectly on the Xoom. Links on the site will stream as well.

Yes, I'm using hardware decoding in Rockplayer and I always used Handbrake for my iPad and Epic without issue. When I use the native gallery video player, the problem is worse, as the video starts to lag just from bringing up the playback controls. This is very frustrating. I will try some different converters and see how that goes.
Dvdcatalyst, I will give a few of your videos a try and report back.
Thanks everyone for your thoughts.

DVD Catalyst works great. I use the stock player and haven't had a single problem.
(Change the video quality to 1750 kbs in the Xoom preset).

i have no problem switching to DVD Catalyst but have one question...does it have the ability to monitor a folder? One thing that is so attractive to me about Handbrake is the ability to use Dropfolders to monitor my DVR folder, automatically convert recordings and dump them into my Dropbox. This makes all my recordings instantly available when I'm on the road.
Thanks

I tried RockPlayer a couple of months ago, and when it was still in beta, but I always come back to the default Gallery. I have never experienced sync or playback issues on the Augen Gentouch, Nookcolor, Droid X and the Xoom, but have heard numerous reports from people for all of these devices (and others) regarding other methods.
For the settings I use in my own software, for all devices it has profiles for) I make sure it plays as it should without the need of installing a different video player. Only for a few older iPaqs and Palm devices do I recommend the install of something else (TCPMP), but for Android, Gallery (or a player like Act1 which acts as a layer around the Gallery player to add new functionality) never gave me playback issues.

Sorry, when I use DVD Catalyst with the XOOM profile, the video comes out a stuttering mess. Here's the info on the files I'm looking to convert...

It looks liek for some reason the framerate of the created file isn't processed correctly.
I noticed you used a SageTV Recording, could you create a small recording and email it to me, or maybe PM me a download link for a small (1-2 minute) clip?

Additional detail
Additional detail regarding my problem - what I've discovered is that the video plays fine but it's only when the controls from Honeycomb are overlaid that the video playback begins to lag. In Rockplayer, bringing up the playback controls don't cause the video to lag, only the volume controls which are native to Honeycomb. Any additional thoughts? I'm thinking about wiping the system and starting from scratch to see if that makes a difference.
Thanks

thanks, I'll have a look at it in the morning. I am working on a small update that includes new Xoom profiles (the settings mentioned on my website) and will take this along in the process as well.

Shocked but I think I figured it out
OK, I'm shocked that I've actually figured out where I was going wrong. The files I was converting and having issues with were recorded using SageTV from a cable box set at 720p. 720p is 60 frames per second and Handbrake was set for FPS to be same as source. When I changed it to 29.97 FPS, I no longer experience issues with video lagging the audio when I adjust the volume or bring up the playback controls. I don't know if this is an important find, but I don't think it's a limitation limited to the XOOM, as I noticed my conversions using the iPad preset are also limited to 29.97 FPS.
I think I can go to sleep now

MKV HD Movie, no sound, video perfect

Hi guys,
I can play normal SD avi's etc perfectly. 720p MKV's video also clean, but no sound.
Tried Moboplayer - no sound
VPlayer - sound, video laggy
mVideoPlayer - doesnt play the 720p mkv
Running 10.1v on Android 3.0.1
I recently came across BUZZPlayer on the market and I've been in contact with them via email, where they claim its plays any file without conversion, and can also play from a smb share...
Havent tried it yet.....has anyone had any experience with this?

rockplayer?
Do you know what audiocodec is used in the mkv?

I have no sound too when i use Hardware Decoding, when i use software i have sound but the frame rate drops and is unwatchable, i`m using rockplayer

I've tried all kinds of video players. I just don't think Android 3.0.1 or 3.1 and Tegra 2 are capable of playing 720P MKV files.

you cannot be serious! lol
on a more somber note, i'm new to this game but i hope your statement is untrue.
if not, this is an epic fail.
The main reason I bought the tab for my dad was so he could freely sync between multiple computers without the help of iTunes and could stream/play most xvid and divx media

I can play some 720P AVI and MP4 files, but 720 MKV's have all been a no-go.
Either video is laggy/freezes. Audio is out of sync. Or no audio.

On Tegra 2 there are no hardware decoder for AC3 sound track (thanks to NVidia/Google/Dolby Licensing org etc. ), so when MKV uses Dolby sound - there is no hardware support so it has to be played in software.
Unfortunately, non of android players can play video with hardware decoder and sound with software (or they just not implemented that way).
Bottom line, 720p and up video is problematic on current Tegra2 devices.
You have couple options:
Sometimes, this issue may be lessen by overclocking Tegra2 from standard 1Ghz to 1.5Ghz - hefty 50% increase in performance, so it kind of manage to play 720p mkv files using software decoder...
Or just re-encode sound track into WMA or something which has hardware driver for Tegra2.

On the sticker covering the tablet screen, it clearly states it can play and record 720p and 1080p. Bastards! I suppose we will get HD playback when the device is obsolete? The point of getting the device when it comes out is so that we can enjoy features we never had before. Turns out, after they taken our money, that Samsung just lied to the world and their piece of crap cant actually play 720/1080p. There must be a codec out there that can do something, I mean come on, WTF.
What the hell is that dual core, Nvidia Tegra gpu device doing with all its hardware? !!!!!
EDIT: Ok, I've been in contact with the developers of BUZZPlayer on Android market. Apparently they claim it can play 720/1080, and that their player is one of the best. Its not free, but its cheap. I am going to give it a try this evening, but I am a bit skeptical. So far the only 2 apps I did buy were both non functional and I got refunded. The issue with Android market is theres loads of crap mixed in with the good stuff. I even see theres an app that filters out all the garbage apps from the market.
Will give an update after I've tested BuzzPlayer.
Apart from Buzzplayer, theres only VLC, which isnt finished yet, which we can hope plays everything. I specifically got this device cause it has the hardware so u dont have to convert stuff. I dont want to convert!

All of you pulling your hair out about thinking the GT10.1 cannot play HD video need to step away from the keyboard, make yourself a cocktail and take a deep breath. It will be okay, I promise. The GT10.1 can and does record and play HD video. For those of you trying to play .mkv files please understand that Matroska (.mkv) is nothing more than a container (think of it like a wrapper around your favorite candy). Inside that container are files for audio, video, subtitles, metadata, etc. The audio and video files are compressed into some format (codec) that can only be played correctly if the device doing the playing has the decoder to read said codec. Tons of people are having no issues playing 720p .mkv files simply because the audio and video codecs in that particular file are supported by their player. The most frequent video codec in .mkv containers is H-264. Audio on the other is typically found in AC3 (as this supports full Dolby Digital surround sound) but can be found in many different codecs. So, if your .mkv video file has H-264 video and AC3 audio but your player does not support either (or both) of these.... then your options are to transcode the audio or video to a supported format (which can be done while maintaining the .mkv wrapper mind you) or find a player that supports the code in your original file. Now, be aware that if you transcode, this results in exponential data compression and thus loss of data. So, audio loses its fidelity and video loses its clarity. Think what happens to the quality of an orginal letter or document when you make a photocopy of a photocopy of photocopy. In order to avoid this you must create the encodings from an uncompressed wave form (directly from the DVD or BluRay) and then place those in wrapper (like .avi or .mkv etc). This is the process of ripping a DVD.
None of this is new. It has been the case LONG before the GT10.1 was released. The perceived problem is exacerbated by people thinking (at no fault of their own) that .mkv (Matroska video) is simply some magical file format that delivers movies in full HD goodness. Its like everything else in the audio/video world on computers, it is always a function of codecs and decoders. E.g. just because I can speak German does not mean you understand me simply because we are having a conversation. You must also understand German.
Sorry for the diatribe, just wanted to clear the air on where the issue lies here. I do think that VLC will be solution for most everyone out there not knowing how to or not willing to play around with encoding audio and video. I know how to do this and I don't even want to do it. VLC should offer support for the popular .mkv file components out there and (most of) our woes will be over. Lets just hope VLC drops there app sooner rather than later!

Please do a easy search on google or on xda on Tegra2 video or Tegra2 mkv. Or go to forums about Asus Transformer and Motorola Xoom and you will find answers on all your video questions.
Its a known issue that Tegra cannot handle "high profile" video in .mkv container. Thats way some people wanted Exynos instead of Tegra.
All most every x264 video you download is high profile and need to
Galaxy tab can handle 720/1080 without problem if the video is coded in the right way.
A great program for converting video is DVDCATALYST and use the XOOM preset setting.
Or you can use this easy program that just change the container and audio so kt can be played on Tegra devices

First off, the GT10.1 can play HD mkv files, one is playing in the background as I am writing this. I will post some pictures and more info on the mkv file later.
second, like I said before, be aware that simply transcoding your audio and/or video to a different format results in exponential compression of the original wave form and thus data loss. If you are truly wanting to watch and listen to your movie in HD you must keep this in mind.

it'll play hd fine. you just have to follow the strict specs to make sure you have a playable file.
no ac3, no mkv container (you can transcode to .mp4 if it's not over high profile 3.1), and may struggle with multichannel audio if you're over SD resolution.
there are plenty of posts on how to transcode or reencode your files for playback on a tegra 2 device in the xoom and transformer forums.

Were in my previously post did i say that it wont play mkv?
The "problem" and that i was pointing at is that it cannot play mkv with "high profile". And 90% off all videos and series episodes that people download is just HP.
And HD is a wide word and can means many things for different users.
Is HD a video with bitrate ~4000kbps and resolution 1280*720? Or is it a video with bitrate ~30000kbps and 1280*720?
A video can have high resolution and still look really bad on screen and some videos have lower res and looks good.
Have had a Xoom for some months and i have found that DVDCATALYST is the easiest way to make your videos play fine on Tegra devices.

Like I mention before, there is no Tegra2 AC3 nvidia decoder/driver available.
I can see only AAC, DTS, MP3, WAV, WMA and WMA pro formats have some kind of hardware acceleration.
There is no way 3-party media player developers can write nvidia's hardware codecs ot its own, they just used them if available in corresponding media player (RockPlayer, VLC etc.)...
If hardware codec is not accessible then most of them use GPL software decoding libs.
So, I would not expect VLC or any other player can do any better then another one.

then how on earth does rockplayer manage to play AC3 sound when I choose Software decoding, but then the video is laggy. Switch to Hardware decoding and video is perfect, no sound....????
Really confused...

Because software decoding uses more resources and is not the ideal decoding solution (can be laggy). The software supports both the audio and video codecs, so they work.
The hardware doesn't support the audio codec, so no sound when in hardware mode.
That's why I love the Original Samsung Galaxy Tab 7. it has 720p/1080p high profile .mkv (no lag) playback, AC3, divx, xvid, .srt subtitle support. All with just a single core hummingbird SOC. (I just wish it were 10.1 inches)
I had high hopes for the Galaxy Tab 10.1, but Samsung didn't put as much effort into the movie player as they did with the 7.
Hopefully, now that Toshiba has issued a challenge with their new AT200 tablet, a Samsung Exynos tablet is just around the corner.

Not sure what people are confused about. MKV is dead, obsolete, and unsupported by current and all future devices. Stop using MKV and you wont have issues. No reason to be using MKV to begin with, no reason at all.

Can you make me a favor and test this 720p MKV sample I made, in all mkv supported players?
I just want to know if you have any lag or audio issues, thanks.
