Wizard Speed Question - 8125, K-JAM, P4300, MDA Vario General

Why is it that an ipod with a dual 90mhz processor can run high quality video at higher framed per second than a wizard that runs a dual 200mhz which can be overclocked to 264mhz? video on an ipod really beats the quality of video on a wizard. just a silly question that just wanted to know.

I'm pretty sure the iPod video has a dedicated video decoding chip that deals with MPEG4/H.264 encoded streams, so the 90Mhz processor doesn't really do much at all when it comes to decoding the video.

What application are you using to playback video? I use TCPMP to watch various video files without any problems (MPEG, Divx). The included Windows Media Player is pretty terrible in comparison. The Wizard will choke on high bitrate and large-sized videos that aren't scaled down to its native 320x240 res. You have to remember that the 200Mhz processor in the Wizard is a general CPU. It's a multitasking processor geared for non-specific tasks, whereas the iPod Video CPU has been designed from the ground up to handle dedicated audio and video. It's not a fair comparison to look at just the amount of Mhz each processor is running at. For what the Wizard is capable of, it's really a nifty device. Although, I wouldn't mind more horsepower either. :wink:

well i found what it was, ipods use the mpg format i think which runs very crisp and clear at high bitrates. the wizard can handle mpg formats crisp and clear too! the only downfall is how much memory it eats on my storage card. the windows media format sucks at handling high bitrates and gives out ugly results on videos. so im going to download my music videos in mpg format from now on . its quite fast and clear exactly like an ipod. thanks to all the replies above. it was really helpful.

Video Framerate with HTC prophet(and other versions)

im seriously considering upgrade changing to a Dopod pro818 but i have a question, i enjoy using my mini as a portable media player using TCPMP with max FPS per compression, if i make FPS 29.97+128kbps audio, will this run smoothly like in my mini or will the 200mhz cpu have problems for media play? i dnt wana get the unit then later finding out that i cant play my favorite movies and videos
those with this unit pls put in some feedback so i can weigh my options
if you encode 320x240 with 29.97fps and 128kbps sound, it is no problem playing on the prophet.
Re:
If you usaually use device for movies & songs, I did not suggest to upgrade Prophet device. Prophet was not good at handling multimedia functions, like movie. I suggest you might look for Atom with 416MHz speed instead of OMAP device.
Or wait for new product update from HTC soon.............

hmmm I'm not so sure. I have gone from the Jam (400mhz) to the Prophet (200mhz), which is a step down in processor speed. I used both for watching movies, music etc. I have found the Prophet to be perfectly acceptable. I watch them using 29 fps 320x240 128kps and it's fine. I have even watched a fully blown divx (700mb) film and it was fine. Maybe there are small artefacts that I'm not noticing, I really couldn't say but if you find it's a big difference in price then perhaps the Prophet is you best option. Obviously if price is not a problem then the Atom is the way to go.
ps. Also bear in mind that you can overclock the omap processor.

keep in mind, that not all OMAP processor can achieve 300MHz...
even, it can render your device became useless...
The OMAP Processor have some issues with Windows Media Player 10... But TCPMP plays just great on the OMAP 200Mhz processor.
I even watch my movies and videos while using my Plantronics Stereo Headset and A2DP... No lags, no skips... Silky smooth video and audio.
Best regards,
Rayan
320x240, 29.997fps, 128kbit audio - performs great and without any overclocking.
playing a full-blown Divx at full quality requires some overclocking though.
I have even streamed a film over wi-fi without problems, however it needed overclocking too.

VOB playback on pocket PC possible?

Hi all, i was just wondering,
now storage space is becoming a non-issue, wouldn't it be more practical just to forget about video compression and play from the raw VOB files? Is there any work going on in that field?
Kuifje
You can always run a program that combines and converts the vob format to MPEG2. VOB2MPEG is the program I am talking about. I don't see a reason to waste 4.5gb when a 350mb wmv has almost the same quality. If you want great quality mp4 at 1.5gb is the best quality for a portable device. The strange thing about PPC video playback is WMP won't utilize 100% cpu usage so if you don't have 400mhz or higher I would guess WMP won't play the video smoothly. TCPMP will utilize as much CPU as needed for the lower mhz devices.
I have been tinkering with my T-Mobile Wing with an 8gb mmc to see how good of quality I can get on the device. I have not been able to get perfect playback with anything other than a smaller format 320 x 240 wmv at best quality. I just do not see Windows Mobile devices as the perfect option for video.
I must say that the PSP and iPhone/iTouch are the perfect canidates for portable video. Bigger screens and better render.
Note: My reply is purely opinion. I have no facts or stats to validate my claims.
vob
Hi neil,
I see what you mean, but it means you could skip the conversion. And subtitles are always a hassle.
Actually I thought the larger the filesize, the lower the cpu laod, because no complicated algorithms required, so it could improve batterylife.
and I was curious.
kuifje
Then I would definitely recommend VOB2MPEG.

That will make it so you can at least play the movie as a single file.

Playing 1080p H.264

As a proud owner of both a HD2 and a GoPro Hero HD helmet cam, I was wondering whether there's a WM video player that can handle 1080p H.264 encoded mp4 files.
I'm not asking for fluid playback, obviously, just a stuttering preview of picture quality while I'm away from a real computer.
Coreplayer has a 1008p limit hardcoded into it, from what I understand, so that's not an option. TCPMP didn't work either when I tried.
Any thoughts?
Forget it straight away. Even a 1.2GHz core 2 duo (which is already easily 10 times more powerful, if any comparison is possible) can't even play 1080p h264 at half speed...
The HD2 can barely play DVD res MPEG2.
1080 on HD2? useless... nonsense
as kilrah said... forget it
but one point is not true u can run 1080p X264 movies smooth on a pc with 1.2Ghz Dual Core.. now comes the point! IF... u have a graficcard that supports VDPAU. so even a loosy GeForce 9400 can do that.
XBMC installing as OS. turn VPDAU on.. e voila. smooth HD movies.
on my mom's AsRock ION330 (Atom CPU) with ION GPU (Equal to GeForce 9400M). 1080p movie with x264 in MKV container run's smooth.
and CPU usage is at 12-40% depends on.
have fun
Have you try the "Remote Desktop Mobile" feature....? Which is not "directly" playing on HD2...
I'm not sure if you fully read my original question:
I don't want smooth playback, I know I can't have that,
but simply a way to view stills out of a large h.264 file.
I don't care if rendering one frame takes several seconds.

Since the video files are on my phone, I don't see how Remote
Desktop Mobile is going to help me. Or did I misunderstand
what you are saying?
Yes we did fully read... But do you really think a developer would spend time making a WM program to open and decode a format that no existing device could play?
It's actually something the WM port of vlc could do, if it hadn't been discontinued in 2006 before it could play h264... It had the same capabilities as on other platforms.
@jisin: Of course if you cheat with hardware acceleration But my example was meant to put things on the same level, as the HD2 has none.
Nobody is talking about a seperate program - at least I wasn't. I would think
any player capable of decoding h.264 should handle 1080p, at least in theory.
For example, I don't understand why CorePlayer has a limit at such an arbitrary
number built into it, otherwise it would probably work just fine for my purposes.
TCPMP is witchcraft, as far as I'm concerned, so I don't readily know why it
won't play HD videos.
AFAIK the profiles used to encode HD h.264 are different from the simple ones used for SD videos, and thus need explicit support. The difference between AVC and AVCHD.
For example in VLC, support for HD h.264 has only come last year, long after SD one. Before that, trying to read one would just give you a couple of crippled frames and crash the player.
Just to clarify, AVC and H.264 are the same, or rather AVC is part of H.264.
AVCHD is an extension of H.264/AVC. That's what you meant, right?
In any case, my videos are AVC and not AVCHD encoded.
I really don't see how decoding a higher definition variant of a video codec can
be any different from standard definition, other than the stress on the hardware
of course.
If not coreplayer, then I think nothing.

Coreplayer's limit is 1008 horizontal pixels, I think, so it can't even play 720p, let alone anything higher.
I have a 720p video clip on my phone which will play in HTCAlbum or Pocket Media Player. It's jerky as hell and completely unwatchable, but it does play. You might find a 1080p clip would play in it too, I don't know. But it wouldn't give you any kind of meaningful preview.
I dont understand why you would want to try and view the image quality of a 1080p file on a 800 x 480 screen? It's never going to look any better than a similarly encoded 480p file. I would agree that it's handier to not have to re-encode files, but most 1080p files are downloaded as mkv anyway, which means that you would need to reencode into MP4. You may aswell reduce the resolution to 800 x 480 and save loads of memory while your at it.

You didn't get the point. He has a camcorder that doesn't have a screen. He wants to put its memory card in the HD2 and have a glimpse of what he just shot could have been like.
But yes, it would only allow checking framing if it took several seconds to load each frame, not much more...
WMP plays the sound, not the video, HTC Album came up with an error I think.
And yes, kilrah, that's exactly it. Should have mentioned that the camcorder
doesn't have a screen.

i think it depends on the codec and bitrate... i can run 1080p h.264 fine on my 1ghz athlon using coreavc
Is there any codec which make possible to view h.264 stream in windows media player?
I can get stream from my internet aceess box which are very smooth with CorePlayer but I would like to know if there is any codec which make it possible with the native multimedia player!
Thanks
i downloade ttansformers hd (1080p) from youtube and coreplayer played that completely O.K. but i couldn't got it to play almost most .mp4 ones. it plays some .mp4 but doesn't many. also plays raw 640x480 videos from my digital camera not smooth but acceptable.
Camcorder that doesnt have a screen???
720p dont play in hd2 forget about 1080, it cant handle the resolution or the bitrates.
I don't know why Microsoft/HTC didnt done things right.
I have HD2 dual boot with Android.
where WM unable to play 720P but Android on same HD2 play 1080 smooth and crisp with out any frame delay/skip.
I think Microsoft has to optimize there graphics driver to come at par with Android.

[Q] Android Video Player?

I cant seem to find a single video player in the Market that plays a range of formats, primarily wmv and avi that I have downloaded.
Any suggestions?
I have to make the commute to work a little more bearable since I broke my Sony e-reader...
i know that the 'rock player' plays avi and mkv files, have you tried that one?
Thanks for your reply, I just checked out rock player and it doesn't seem to work.... opens the video for a split second before closing it again...
I guess I'll keep looking.
Any dev looking to port VLC over to android?

oh thats strange, it works on my hero (they have different versions for different devices, make sure you downloaded the ARMv6 one)
but tbh its not great because theres a lag between the video and the audio, most probably because of the hero's slower processor. i'm looking for a good video player as well
Hmm.. Rock Player started to work by itself.. kinda.
Plays the video for about 15 seconds (very choppy, even after all tasks killed and using a blank Sense Scene) and then freezes the phone, have to remove the battery..
Have u overclocked?
My hero wouldnt run RockPlayer on 691MHz as MAX. Had to down it to 652.
in the end i deleted it, since the video was choppy. i guess the processor just isnt up to handling large video + i hate ruining films on a small screen.
there are some forum posts on VLC Forum about porting to Android... i think the conclusion was that it wasnt going to happen?
My phone is indeed overclocked, to 672Mhz.
I'll try messing around with the OC settings and see if it makes a difference.
I know the processor is *only* 528MHz (stock), but I remember watching videos perfectly well on my Packard Bell 166Mhz, 32mb RAM, 2mb Video card pc...
I think Android should be doing a LOT better with with handling Video, see my post in the "Android 2.3?" thread...

There is a significant difference between the low quality avi files of the past and the h264 mkv content of today. Some of the recent files require a minimum of a 2GHz processor to run (understandably 1080p content, but still). And lets not forget about the instruction sets which provide desktop cpu's with a boost in those areas. Furthermore, considering your phone only has a cpu and no dedicated or otherwise gpu it isn't all that surprising.
Even running an average quality dvd rip avi file my CPU is running at between 15-25% and I have an overclocked dual core 3.33GHz intel cpu E7300 (25% is roughly 833MHz). Not to mention GPU usage, which at this time I can't be bothered to record.
I understand that this is not definitive evidence but I am using it to show that you are simplifying the problem. TV shows and movies that are ripped now have much higher quality resolutions and bitrates than those of the past, it is not surprising that they require higher processing power. Realistically a 528MHz low power phone cpu is unlikely to be able to keep up with these improvements. Just like the low power Intel Atom desktop chips fail to run 1080p video (even the dual core one) running somewhere in excess of 1GHz (think its 1.6GHz).
That wasn't meant to be such a huge rant...
HAHA! I know I totally simplified it but I guess I was just trying to say that a smart phone in 2010 should be able to handle video with no problems...
My upgrade is due in January, so new handset here I come!
Will be funny to see the (still awesome, despite my rant) HTC Hero become my backup phone...

[Q] Xoom HD playback capability

There are a lot of MP4 video clips that I cannot get to play on Xoom smoothly but they play back really well on my HTC Desire.
On Xoom the video is laggy while the audio is audible. This happened to both 720p and 480p videos. I used both the default player and Moboplayer to ensure I am using the hardware acceleration.
Strangely on my Xoom the Moboplayer can soft-decode 480p MP4 with ffmpeg and playback without any problem. 720 is smoother but the decoding was too slow which resulted in A-V async.
Again, all those clips play really well on my HTC Desire. Tegra 2 should be able to handle them.
Anyone knows anything?
Please search the forum before asking questions. This has been asnswered.
The problem you're having is to do with the clips using high profile encoding.

Yeah, well, I don't agree.
I converted 2 720p mkv 90 minute movies and a 40 minute 720p mkv TV show last night and it took 6 hours. This was done on an Intel Core 2 duo P750 2.26GHz
Not everyone has the same hardware. I suppose I could run out and buy an i5 or i7 for the sole purpose of encoding video for the XOOM.
Maybe Motorola can partner with a PC company. How about 20% off a new laptop when you buy a XOOM that way you will be able to take advantage of its HD video capability in 2 hours instead of six.

It all depends on your settings, and keep in mind that the imac is going to have similar hardware to your machine. The recommendation is to set max width to 1280, set B Frames to 0, turn off CABAC, 8x8 Transform, and Weighted P frames. If you do that, you'll find fairly consistent encoding times even with older hardware. Also, keep in mind that encoding is entirely processor bound and will do better the more cores you can throw at it.

Been there done that. There are no shortcuts. Good quality takes time or more cores. Or harness the GPU ie CUDA but that causes horrendous macroblocking in bright scenes.
No matter how you sugar coat it, re-encoding video is a time consuming pain in the ass for most people.
I also seem to remember there are multiple versions of the imac, with variable hardware specs, from dual core up to quad core 3.6GHz - so your claim of similar hardware seems unlikely.

>I converted 2 720p mkv 90 minute movies and a 40 minute 720p mkv TV show last night and it took 6 hours.
Suggest using 800 max width for substantially faster encode speed and smaller size. Quality diff is negligible on a 10".
If using 2-pass, switch to 1-pass for both faster encode time AND better quality.
Unfortunately, HB doesn't provide x264's speed presets. You can gain additional speed (at cost of some nominal size increase) with the faster presets. Hmm, I should update my HB script to allow "downloadables" as input.
>The recommendation is to set max width to 1280, set B Frames to 0, turn off CABAC, 8x8 Transform, and Weighted P frames. If you do that, you'll find fairly consistent encoding times even with older hardware.
Encoding to baseline profile (what the above basically means) gains speed by disabling more advanced "compression" features. The trade-off is significant size increase, about +30% vs high profile.
Using a lower res allows more efficient settings. At 800 width, you can use main profile. Speed diff between main & baseline is insignificant. Speed gain for the lower res is substantial.

I appreciate that your trying to help, but those are the settings that I have been using already: 1280, set B Frames to 0, turn off CABAC, turn off 8x8 Transform, and turn off Weighted P frames....
and it is still taking well over 3 hours to re-encode a 1:30 movie.
I understand that lowering the resolution will decrease the encoding time, but I consider that a last resort compromise. In fact I would consider that basically a failure of the XOOM.
I have considered buying an i5 or i7, but I feel stupid buying a new laptop for the sole purpose of encoding for the XOOM, when I could just pick up my Galaxy Tab and just play these videos immediately. No encoding. Just copy them over and play.
I am quite sure those videos are not high profile. Their bitrates were around 2M, way below 20M.
And, as I said, I can even do soft-decode to play the 480ps which does not play well with hard-decoding.
480ps, man. 480ps. Stunning.

I don't really care about the encoding stage, I have an i7-950 which encodes a blu-ray in handbreak in well under an hour.
What I'd like to know, is are the codecs really this lacking, and will we see a solution?
I, like the OP have a HTC Desire and I could be devastated to find the XOOM can't handle the videos my Desire can.
Does it natively support mkv? I like to watch TV episodes in mkv like the 86MB Big Bang Theory episodes.
All my non-TV stuff I rip myself so I'm not concerned. Other than the DRM wmv I buy. Which play back fine on my galaxy tab.

Most TV shows that are 720p mkv, and are privately enoded, and downloaded, average about 1.2 GB and will and not play. Support for MKV as a container isn't a problem, its the profile of the h264 video in the container that is the problem.
If the Video that you like to watch is only 86MB, that doesn't sound like high profile 720p. So it might play, only way to know is to try or download mediaInfo and check its properties.
Good to hear that the i7 that you have can do a blu-ray in an hour. That sounds like what I should do eventually. Wonder if an i5 will do as well. I've heard that the i7, though it has 4 physical cores, is seen as 8 due to multithreading, wheras the i5 is limited to 4.
I watched two re-encoded episodes of fringe last night, and the Video on the XOOM is really amazing. It actually is almost worth the wait.

They're not 720, but they're nice enough on my Galaxy Tab. They are High Profile @ L4.0 though which I'v heard a lot of bad-mouthing about on the forum lately. I'm no expert on media codecs and frankly couldn't care as long as theyre watchable. I'd love to know I could rip my Blu-Rays at 720p and watch them on the XOOM comfortably though.
What you are posting is interesting. Its high profile, but low bit rate. Some of the early claims for the Tegra 2, which is used in the XOOM, said it actually could play high profile but only at a low bit rate, but I haven't heard it confirmed. I suspect this video will not play, but later on I will try encoding a video in a simliar manner to yours and see what happens.

Great, if you like I can dropbox the file I have and PM you the link for testing. These files playback flawlessly using the Galaxy Tab with every single player software I have tried, whether hardware or software decoding. FOr them not to play on the XOOM would be a killer.
Got your file. Sorry, it plays but with no sound. I tried RockPlayer and Moboplayer and the System Player and all play the same - silent.
The Video is actually pretty good. Smooth and very acceptable. So I guess it can technically play high profile, very low bitrate files - just not with sound. Have to Play around some more and see if I can learn anything else that might get this to play correctly or figure out what the problem is.
Edit: Actually, this is a Divx encoded file, not h264, so that is why it plays. So I am a little surprised about the lack of audio. And its only mp3 audio!!! This is really amazing. I can't believe the XOOM isn't playing this correctly. Has to be a way.
Update: Ok, success! It does play correctly in Rockplayer in software decoding mode. With sound. So it looks like you will have no problem.

Interesting, if somewhat concerning that it won't play this in the standard players or with hard-decoding even though it uses mp3 audio.
How about VPlayer Advanced? I find this plays most of my videos nicely on the Tab.
Probably just lack of Divx support in hardware. Thats not a big deal, even a single core CPU of lower power can easily decode low res, low bitrate Divx. I don't consider that a flaw at all. Software decoding video like this with the XOOM's dual core A9's is trivial. Results are fine. Just need an app like RockPlayer that does it. XVID files will probably not work in hardware either.
From Motorolas website:
PLAYABLE FORMATS
AAC, H.263, H.264, MP3, MPEG-4, ACC+ Enhanced, OGG, MIDI, AMR NB, AAC+

Yeh that's pretty fair I guess. How do you think it would manage if converted to MP4? I can do it on my 950 when I get home and send you it if you like? I'd not mind converting the whole lot if it played in the stock player.
