Ok i have 1080 movie on my vibrant the default player does not support it so i downloaded the rock player. It works in there but it lags.....
Help.... How can i play 1080p on my vibrant
Doesn't 1080p video require more horsepower than is available from a mobile phone ?
Rock player is a software accelerated player vs. The stock hardware accelerated video player. It plays a broader range of codecs but relys on the cpu for video decode so can't do hd video or video with high bitrates.
Unfortunately, you wont be able to make 1080p content watchable on your phone without a reencode at 720p in one of the right formats or less with a non standard format.
Like previous post called into question, the hardware in fact, on current smartphones isn't capable of rendering 1080p content, unless the bitrate is cut down significantly enough as to make it almost unwatchable.

your wrong i just converted the same movie to avi and it works like a charm. VIBRANT DOES PLAY 1080P THE QUALITY IS AMAZING...
You are aware that your phone's resolution is 800x480
1080P resolution is 1920x1080
Therefore, all that extra resolution is for nothing. You're phone can't display more than it can. So 1080P is a waste, 720p is also a waste. EXCEPT for the fact that it is easy to find software to encode to 720p, OR if you are going to use video out.
I have been running a few tests on Handbrake transcodes for my G2, and I wanted to share my results for anyone who doesn't wish to invest in 9 hours of transcoding/CPU time, just to get sub-par results.
My test file was Dexter S05E01 in the form of a 720p mkv. I tried 4 different settings, and here are the results:
1.) 1280x720 mp4 at constant RF 20. The picture is very sharp, but the playback stutters. Audio is fine, but the phone can't keep up with the video (when played in the stock player, doubleTwist, Vplayer, and QQplayer).
2.) 1280x720 mp4 at constant 2550 kbps. The picture is also very sharp, but the video playback still stutters, even when played in each of the alternate players listed above.
3.) 800x448 mp4 at constant RF 20. The picture is still sharp, yet it STILL stutters. The phone just isn't keeping up with the video. This one confuses me, since it's less than the phone's screen resolution.
4.) Handbrake iPhone/iPod Touch settings at 480x320, with constant RF 20. This is the only one that plays without stutter, but it is noticeably less sharp than the previous three tests. Played on my 3rd gen iPod Touch, this encoding looks fantastic. However, my goal was to maintain the HD feel of the source, and this was not achieved.
I will continue to experiment with different file-types and report back here if I succeed at finding a crisp, yet playable transcode for the G2.
Are you playing the videos using the built in media player? If there's lots of stutter I would try rockplayer. Don't download rock player from the market, its the universal version and is very slow and stuttery. Go to the website for rockplayer and download the version specifically for the cortex A8. I can play 1080p downloaded youtube videos with that.

^^^^^This^^^^^
I use Rockplayer for all my movies without having to transcode ever!
Am I missing something? I went to the rockplayer website but only see versions for arm7 and arm6.
It's ARMv7.
I downloaded it, but I'm still getting stutter, even on the 800x448 file. h.264 is the right codec, right?
Perhaps it's because I haven't rooted my G2. Maybe 800MHz isn't fast enough to decode 720p. Are you running CM at 1.4GHz, to get your 1080p videos playing with no stutter?
Also, to be more clear, it's not a huge stutter - only very subtle. However, it's enough to really bother me, because the video is never really smooth.
I'm running CM7 at 245 - 979 mhz ondemand with the UV kernel. Have you tried playing a 720p youtube video downloaded with something like tubemate?
I did notice when I played a converted version of inception once that it stuttered, yet youtube 720p videos didn't stutter at all.

I guess you're right. There is a small stutter... but its much less then when I was trying to use handbrake and convert full movies...
Sent from my T-Mobile G2 running Cyanogenmod.
Yeah, I tried a 720p youtube video in RockPlayer, and there was still enough stutter to bother me. I guess I'll just stick with my iPod Touch for watching videos on the go.
I used a guide for HandBrake with G2-optimized settings based on the iPod Legacy preset and the mVideoPlayer app. I also have the G2-Fast kernel and overclocked to 1516 with SetCPU. It works fine enough, but the files it generates are only marginally smaller than the source. What is the homepage of RockPlayer? The first result on Google is broken.
The first Google result works for me.

Hopefully the next iteration of Android (Honeycomb) will be able to use it's gpu acceleration features on videos?
ARMv7neon, ARMv7vfp, or ARMv7vfpv3d16? They're all ARM7, whats the difference?
Personally I wasn't able to get Rockplayer to work on my G2 for some reason. I tried both versions of the ARM6 and the ARM7 version as well so I'm unable to view any videos at the higher quality. But here are my settings that I use.
Picture: I keep these at DVD quality, so my width is always at 720 and I have the box checked in "Keep Aspect Ratio"
Video Filters: I have all of these to off.
Video: Video Codec is at H.264 and Framerate(FPS) is set to "Same as source". Quality I have set at 60.78%RF:20
Audio: Source=Automatic Audio Codec=AAC9(faac) Mixdown=Automatic Samplerate=Auto Bitrate=160 DRC=0
I don't touch the "Advanced" box
I also have the "Container" box set at MP4 with the Web optimized and iPod5G support boxes checked.
Lastly I change the .mv4 to .mp4 at the end of the file.
These are pretty much the same settings at the iPhone & iPod Touch presets with just a few differences.
I've never had a problem viewing any movies with these settings and the quality, I feel, is excellent. I've converted hundreds of movies using these settings ever since I've had my G1. The only difference is the Video Width. The G1 I had set to 480. Hope this helps.
One other thing to add. These were all either direct DVD or Blu-ray rips so I've never seen any real loss in quality.
Thanks, darkjuan. I'll give those settings a spin and see if I have more luck with them than I did my original settings.
Hi everybody. I am running Phiremod 6.2. What I really want is to be able to drop a standard definition video on the sd card, such as a divx or xvid file on the and have it play back smoothly on the nook. It seems that hardware video decryption doesn't work and that is the reason we are stuck using software decryption. What is the best video player? Even with the best video player, do you still need to re-encode the videos to lower resolution for proper playback? What format do you re-encode video to? Do we expect hardware video decryption to be accomplished by the amazing xda hackers?
Thanks!
I use Mobo player for playback. Have encoded several standard def videos from a TV series using Handbrake with the nookcolor preferences created by someone else on this forum, in H.264 format. They look and sound very good this way, except it does not fill the screen which is expected as it is standard def. Have not tried any HD content yet.

Isn't Phiremod just a modded CM7? CM7 suppports hardware decoding, for up to 480p files (max 854x480). Anything beyond that will be soft decoded. Anything that isn't expressly supported by Nook's "supported" video/audio formats are, afaik, also software decoded (the base player will not do this, need something like vitalplayer or rockplayer, etc.)
- If a video is just not a supported format but is 480p and under, it runs very smoothly for me in CM7 as software decoded -- you wouldn't be able to tell that it wasn't hardware accelerated.
- If a video is higher than 480p (720p, etc) or the bitrate is too high, even if it is the supported format, it will also attempt to be software decoded. My experience with this is that it's poor quality (stutters, audio desync a lot of times, etc.)
MP4 container, H.264 baseline codec for video conversion. Anamorphic loose, 854x480. AAC / MP3 (I forget what else is supported) codecs for audio, choose 44.1 khz sampling rate instead of 48khz to avoid problems. Bitrate for video and audio are up to you, but I wouldn't use the lossless setting for H.264 because you'll have issues with it playing (and will be an enormous file). You also really don't need to use it for a 7" screen. For me, video bitrate of 800 kbps (avg) is low but acceptable, 1100 for medium, 1500 is (non-HD) dvd quality. 128-160 kbps audio, your choice.
There's a lot of players out on the market, many free. I like Vital Player Neon a lot but the paid app version failed on me because of their self-copy protection. I use Moboplayer and also installed the Neon codec from the dev's website, it improved my performance noticeably on some more system-intensive videos.
As always, YMMV.

Is the <-> (vs >-<, etc options) not working for you to expand it to full screen? I have not had any issues getting 480p content to edge-to-edge (provided it's 16:9 aspect ratio, which many shows and movies are. While Nook's resolution isn't true 16:9 it's close enough that you won't notice any real edge). The only videos that display with bars for me are the wider aspect ratio ones.
(On stock rooted firmware, with 1.1Ghz OC)
I also use handbrake... encoding to 1024x576 xvid seems to do the trick with mobo player. (Altough so far I tried only one video file.)
edit: tried an other one, plays almost perfectly in sync. It is about 1 frame out-of-sync that can only be noticed with hard, fast sounds like slapping.
Encoding to h264 with the said resolution results in video being played back slower and of course audio being out of sync.
480p h264 baseline / aac mp4 files can be hardware decoded and play nice, but I'm all for the bigger resolution.

The ones I did were not in 16:9 aspect ratio, they were 4:3 which is why I believe I could not expand them to full screen. I haven't yet tried a 16:9 video like a movie but will soon.
in addition to the formats/resoluton mentioned try using Vital Player Neon - works with a lot of formats - plays really smooth on my NC (CM7 7.02+1.3GHzOC)
Thanks a bunch!
I'm using rooted official 2.3 rom. when I play mkv 720p movies , video plays at lower frame rate than usual and problem in audio video sync. I use mx player and hardware decoder is not available for mkv. can please anyone suggest me some tips to play 720p smoothly. and is there hardware decoding available in new adreno driver in dzo ics for mkv?
I m using bsplayer lite tha supports mkv.
720p on nearly 480p device?
Professionals can correct me, there are few reasons why it won't play in full speed:
1) .mkv files need usually the same space as .mp4, but it has better quality. BUT needs more power to play. That is the disadvantage of matroska. So if there is too high bitrate on the video, it lags/wents off sync. Overclocking might help.
2) 720p??! Really? This phone CAN record 720p video with good fps, but only in good light conditions. You can even watch them (because they are so low-bitrate), but if you have like 720p movie, it lags due to high bitrate it needs to look clear. BUT why would you want to play 1280x720 (16:9 ) resolution video in 800x480 (16:10) resolution screen? Shapes will look odd... I would prefer 480p (854x480).
3) I'm guessing that your movie is on your memorycard? If your memorycard is too slow, can that be the reason for lagging too. This can be fixed with faster memorycard.
4) Switch to Moboplayer. I don't have any experience of mxplayer, but Moboplayer can use hardware decoding for that.
Our Android app is currently not able to display the full-quality of video's. The same MP4 that is played in the app (and even by the standard video player of the tablet) is shown in a significantly lower quality than while f.e VLC / VPlayer is used on the tablet
We use a Memopad 8 (ME181).
What would you recommend, which is not too time-consuming?
