If i wanted to watch a movie what's the maximum BitRate can I run? for example my macbook can't run anything above 35Mbps while my Note 10+ can run up to 75Mbps so far ( i have not tried anything larger than this so far).
You can see the max supported bitrate of all video decoders on your device by Media Codec Info.
For my Tab S5e, the max bitrate of hardware accelerated Qualcomm video decoders is 100 Mbps (HEVC, AVC, VP8) and 60 Mbps (VP9). But, I have no problem to play 4K, 10-bit test videos with 200 and even 250 Mbps bitrate. See some video bitrate test files here:

i am unable to play 1080p videos. either the player says the video cannot be played or the video plays but with a lot of lag. i have tried both in mkv and mp4 format. im using folio mod 1.4 and fix for this?
What bitrate are you using when playing MP4 files in 1080p?
I've been able to play 1080p using either MOV or MP4 with the Toshiba Media Player.

It just hit me! its cuz the video file is in my external micro sdhc which is only class 2 so that cant cope with the data rate required for the video.. will try and place the video in internal mmc and see what happens!

Yes class 2 would probably not be fast enough. I'm using class 6 and that works fine with MOV and MP4 in 1080p. I'm not sure about the bitrate but it would probably be in the same range as your file.
1080p in mp4 works fine on my device, although it FCs after a few seconds both with mVideoplayer and Toshiba Media Player when I try to play mkv files. Is that a known problem?
mddsd, dj_jokke, can you try to play this file?

It's a 1080p .MOV file from a Canon 550D, it contains a h264 track with a bitrate of 45mbps, and a PCM track of 1.5mbps
Can you try to play it and tell me if it runs smooth? I need a tablet like this to watch videos of the camera without carrying a notebook
The ipad and the iphone4 can play that file flawlessly, but I want android that does the same

I've tried your 1080p .MOV file and the Folio can play it (I'm not sure about the sound).
Although every 4 second there is a freeze in the video for about a split second.
It's enough to get annoyed when watching the video...
Tegra 250 has some known limitations when it comes to high profile video.
A video with a bitrate of 45 mps would probably fall into the category of high profile video.
Although I'm not quite sure if this is the reason for the slight freeze in playback.

Thanks a lot for trying!!
This is the info of the video track, its a Baseline 5.0 h264 stream. Maybe tegra 250 supports it 1080p decoding even at baseline 5.0, but can't do a smooth playback with 45mbps.

speaking of MP4 H.264 play in Gtablet...I suspect the 512MB RAM is not enough juice so 1080 can't play smooth (choppy) in the device.
I convert most of my movies to 720x480 MP4 H.264 and using hardware encoder to (QQPlayer, VPlayer) play and very smooth play but 1080...very very choppy, doesn't matter MOV, MP4, MPEG4, MPEG2..etc
And Yes, if the 1080 movie length is only 10 or 15s (4MB or 8MB), it will looks good (so you see the marketers show the device capable for 1080)...but in the reality, 1080 movie with 7 min (~1.2GB) plays like CRAP LOL...
I wonder how smooth they can be played in Asus Transformer tablet - but I ended my own saga here by staying with 720x480 MP4 H.264 format - good enough for my kids watching 10 movie in the long hour drive!

1080p is 2Mbit per frame, and is larger than the actual display, so it has to be scaled down to 1024x600 as it is decoded - at 24 frames per second. The mp4 (or other) decode + scaling without GPU acceleration is the problem, not the availability of a couple GB for frame buffers.
At a minimum, rescaling your video to fit the native resolution would probably fix it. Most people just don't want to bother
Ram has nothing to do with it ( well it does but even 128 would work )
Its like schettj said, the GPU accell or CPU accell / Multithreaded decode thats the problem.....Ie....Software is the problem.
I've been trying to find the best encoding settings for HD/720p H.264 video for G Tablet with Handbrake and I'm not having much luck. I've followed this article for Notion's tablet (since its also a Tegra 2 tablet) and while the picture is great the playback is jittery. I tried lowing the RF (under Constant Quality) to 25 but it produces the same jitters.
Changing the video codec from H.264 to MPEG-4 (FFmpeg) actually produces little to no playback issues but the picture quality isn't as great (its still good though), but I prefer to use H.264.
Any one have any luck encoding HD H.264 video for their G Tablet? If so, can you share your settings?
Thanks in advance
P.S. - I'm running VEGAn-Tab 5.1.1 and using VPlayer, RockPlayer and QQPlayer to play back the videos (they're all suffering from jittery playback).

this is a view sonic special proset from foxreal video tool, for your refenrence
It seems my TV will not support streaming video from my TB that is less than 7,900 Kbps (just under actually).
So if 720p is the highest resolution what other setting could be used to maintain 7,900 kbps?
Does anybody have that?
For example Apple has listed for its Ipad4
Video formats supported: H.264 video up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG‑4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format

Where are these specs from samsung or google? When I had my Ipad 4, this helped GREATLY with converting movies to the proper format.

Sort of a moving target.
The Exynos 5250 has native support for: MPEG-4/H.263/H.264 decoding and encoding and decoding only for (MPEG-2/VC-1 and VP8)
Source:
http://www.samsung.com/global/busin...t/application/detail?productId=7668&iaId=2341
BUT
The actual wrapper formats supported nativley and in what players depend on software support. Everything will play on the processor in software mode through a cpu decoder like FFMPEG being used by MX Player or BS Player from the market place (free). But software mode is not the most efficient mode and will drain the battery at a faster rate than native HW playback.
Here is what I know seems to work so far in the native player: MP4/H.264.
If anyone else has had native support with something else sound off. As to a spec sheet that is the best I can show you, but as I said it is not representative.

Are you able to smoothly playback mp4's?
If you are..what frame rate and what avc works for you best?
Step 1: download MXplayer https://play.google.com/store/apps/details?id=com.mxtech.videoplayer.ad&hl=en
Step 2: make sure your content isn't 10-bit (hint: most likely it isnt)
Step 3: Your content will play. Basically 99% of regular content will work. To be honest, I cant think of anything that hasnt worked for me, and I play high-bitrate anime with advanced substitle scripts (ASS-subs). It works fine.

Yes. Most of the MP4s I have tried are H.264 standard 30fps and up to 1080P. All worked on the native player
For other's experiences with MP4s up to 60fps and 1440p see this thread:
http://forum.xda-developers.com/showthread.php?t=1995176
If you are using a player like MX Player and are trying to play an Mp4 Muxed into an MKV then the video will play with hardware and you can select software for the audio (right now. this may improve in the future).
As the other poster said. Almost everything will play with MX Player. It is just a question of whether it is played using HW codecs or SW Codecs. HW codecs use built in decoding capabilities on the chip to vastly reduce the workload on the processor. SW decodes everything on the processor and then pushes it to the screen. The only difference between the two from a user perspective is efficiency and battery usage. (and on super-res files there may sometimes be slowdown in SW mode)
To be honest I have tried everything from mkvs to rms to movs to wmvs on MX Player and ALL have played successfully in the SW player.
