[Q] video playback on latest cm7?

Hey guys,
I think I read somewhere that the nook color CM7 nightly builds got the functionality of hardware supported video playback(?) Is this true? Does this mean I can play .avi (DivX and xvid) files smoothly using something like yx player/rock player without having to convert it to .mp4?
I am contemplating a nook color. All the other features seem great. Looks fun to mess around with. A good video playback would be an additional plus for me

I have had pretty good luck using Moboplayer and a bunch of videos I made with Handbrake for my iPod touch using the default iPod Touch profile. They are playing well and look good. Handbrake is free and it works pretty fast. I know you said you did not want to do MP4 but you might take a look at retranscoding.
I'm using CM7 nightly 102.

As good as Stock 1.1.0?

pgrunwald, have you tried .avi files?

Okay. Hardware Acceleration will only work with specifically encoded for Nook Mp4's. (Yes videos for ipod touch, etc... will work, as their resolution is under the maximum the nook can handle) For more information as it's just to much to type... Look up the video threads by Dalingrin and Chisleu, they have all the information on that.
Now .Avi files. Play fine in software mode in any of the players you listed. That said, I'm gathering if you're watching an avi file, it's not over 720p, as that would just be stupid... But common "scene" releases of unmentioned files, do play fine.
720p Mkv's however absolutely require the OC kernel and in my current experience, the .29 kernel based CM7. The .32 kernel at this point seems to have trouble with 720p, it's not unwatchable, but it did stutter from time to time on my NC.

I'm using vitalplayer neon and it works fine for xvid avis. I didn't convert anything or check anything. I just used a file that I had downloaded to watch on my desktop. It stuttered a bit at the start but played smoothly after that. I was amazed. NC keeps doing more. I wasn't even overclocked at the time.

Could you elaborate on this a bit more please (bitrate, framerate etc.)? I could never play 720p on my Nook. Currently I have one of the recent CM7 nightlies, and even OC'd to 1300 no player (Mobo, Rock, etc.) can't handle any of my 720p mkv's properly. It was also the case with OC'd .29 kernel. It's not that it just stutters every now and then; it's a heavily slowed down slideshow.

Videos work great on Nook color CM7.1 nightlies. I use the built-in player and use handbrake to convert my videos.

To be honest, I can't really give specifics as the files are long gone that I did use. I was fully able to watch things like 720p trailers (Pirates of the Carribean) and the anime series Kaiji 2nd in Mkv at 720p.
If I get a chance I'll take another look.

Well if nothing else, I can guarantee playback of anything under 720p without encoding.
Anything above that is honestly overkill, not only for size of the file, but for the size of the screen; you just won't see a difference between a properly encoded dvdrip and a 720p bluray-rip.
That said, if you're like me, where you have certain files that are already encoded at 720p and would rather not "re-encode" or "re-obtain" them, then I can honestly say (in my experience) that the .29 kernel nightlies or Phiremod 6.2 with OC kernel (4/24) has played 720p files fine in Moboplayer. Not only has it played them fine, but it's not had a problem with soft-subtitles. Again though, this is from my experience in the past and I've been switching between .29 and .32 kernels, so I've been avoiding 720p files like the plague.
.32 kernel may be able to play 720p in the near future however, Dalingrin has responded a couple of times to my one man complaint team about the difference in video playback in the two kernels, and he's said that he is currently working on some major overhauls of the system that may or may not help address this issue.

so what I gather from here is that it handles video fine, even .avi as long as it isn't 720p? I also read something about it handling flash video fine @ 800mhz, 720p..?
here's the article:
http://www.engadget.com/2011/06/29/cyanogenmod-7-on-the-nook-color-hands-on-video/

RE AVI - I'm sorry, I have not had time.
I did make a handbrake MP4 file using this profile and it played great: http://forum.xda-developers.com/showthread.php?t=894165&highlight=handbrake

Flash video is a whole 'nother ball park. Again, I find .29 kernel to be the best at handling flash and have personally had problems with .32's kernel for longer videos.
That said, I'm one of the only few complaining (possibly the only one), so it's possible it's just me or my source sites/files.
720p flash I'm going to assume to be dodgy at best, there are few tablets on the market that I know of (i.e tegra 2 processor) that still have trouble with 720p flash videos.
That said, flash videos of Standard quality look fine, and the youtube app allows you to play HD (I'm assuming it's 480p) videos without fail and look very nice.

use rockplayer lite

I completely understand not wanting to reencode your videos but keep something in mind. If the video can play in the stock video player then it will be much, much better on your battery life. If a video plays in the stock video player then all the decoding can be done with the DSP co-processor. Leaving the CPU sit nearly idle which will result in dramatically less power consumption. Just something to consider.
And yes, better video playback may be coming to CM7 in the near future if I can get a some changes in. Perhaps even DSP 720p decoding...but shh, you didn't hear that from me. Oh and maybe even *some* flash hardware acceleration though I won't know if will work until I can test it since its closed source.
Don't get your hopes up for the last two because they may or may not work with the changes I have planned.

it's been really cruel of you to have woken up those hopes!!!! After all that time I reconciled with the fact I have to reencode vids...
Keeping my fingers crossed. If you achieve that, I am going to write a script which keeps tapping "donate to Dalingrin" at Nook Tweaks every time I watch 720p

Haha, even with 720p support you will still likely need to reencode many of your videos due to the codecs being picky.

[Q] Playing nHD & HVGA videos

My ARMv6 is overclocked at 800MHz and I'm curios is there a way to make 360p and 480p videos play smooth on our Mini?

I once tried 175MB .avi (624x352). Played smooth.

ok i tried it too thank you played an xvid movie smooth with mx video player...but flash video with flash player doesn't work as expected probably because uses hardware acceleration instead of software deocding

You mean directly playing flash videos in browser? If so, I don't think it's possible to improve that.

YouTube problems

Hi all,
I started out with the stock 3.2 ROM, I quickly switched to Overcom ROM 3.2. I was happy with it for about 8 months.
Then I decided to go to ICS and later JB.
Every ROM I've used so far has the problem that HD movies on YouTube don't play very well. Every few second it will stop for a fraction of a second, it's really annoying. The audio is never affected though. It happends when the video is small and when it's full-screen. The moment I switch from HD to HQ the problem is gone.
I tried about anything, even overclocking up to 1.5 GHz. doesn't change a thing. I'm pretty sure it's not the capabilities of the tablet, if I play 720p trailers on the IMDb app it plays all video's perfectly. Also, when I use the 3.2 Overcome ROM backup the problem is gone as well! I can't go back to 3.2! I love ICS and JB too much!
Are other people having this problem? Or does anyone knows the solution?
I was wondering if this has something to do with the kernel, so far I used the A1 kernel and currently I'm on 3.1.10 Cyanogenmod+ kernel and CyanogenMod 10, with Android 4.1.2

Again, from the Asus Transformer Forum about the Tegra 2 and HD content -.- :
"The Tegra2 chipset are designed as a mobile sollution chipset - to support web 2 standards. The highest encoding profile used here (Youtube 1080p) are 1080p baseline and this the Tegra2 chipset will both record and play with no troubles. As well as 720p baseline and main profile - but only upto L3.1 with some limitations. It doesnt matter which container is used (mkv, mp4, m4v, avi etc) and it doesnt matter if resolution are 1080p - its only a matter of the encoding profile used to encode the supported video format H264
Tegra2 will NEVER be able to decode High profile L4.1 encodes - it's not a software issue, neither in terms of Honeycomb or Nvidia libs, its simply a limitation of the abilities of the hardwaredecoder in the Tegra2 chipset and this will never change. It is also not a limitation in the Transformer specifically, but a limitation in ALL Tegra2 based tablets and mobilephones.
This is the same reason why some mediaplayers like the Boxee Box that was originally intended to use the Tegra2 moved on to an Intel chipset before launch.
In short the Tegra2 chipset will support playback of videos encoded in 1080p or 720p resolution, using the H264 video codec and AAC audio codec - as long as the video are encoded after the baseline profile standard
It will not now or ever - play 1080p/720p encodes encoded after the high profile standard."
Youtube HD is not encoded as it has to be for Tegra2 chipsets to play without stutters..
Next time, please serach the forum, there has been several threads about hd content.

While I agree the issue was mentioned before (it's even on my faq ICS), none of your reply addresses the observation, made by several folks on this board, that certain (youtube) HD videos played fine in HD, but stutter in ICS. Or did I miss something?
I read a suggestion somewhere, that video would stutter less in ICS (correction: jelly bean) if developer USB debugging mode is off, but I didn't see a difference...

Well, i have to admit that youtube hd videos did not play fluently on HC for me. Therefore I think that the android version or kernel doesnt matter for decoding. I might be wrong though..
With that being said, i think that there is no solution to get it fixed.
Btw that USB debugging thing does not work for me as well

Which rom best for watching videos?

I like to watch movies on my tab, then and often stream them from my pc. I'm just wondering which rom you guys would choose as the best for this? I'm thinking of going back to the cm9, currently on 10.1.
I seem to remember having less issues when using cm9 to do this, though in general I didn't find the rom ass smooth. But many of them are 1080p and I'm not interested in reincoding anything.
And is mx player still one of the best options for this?

Honestly, I have no problems streaming and watching my 720p collection from my HTPC on my stock ROM (4.1.1). I am using MX, and even though it didn't request a codec, I still installed the ARM7-NEON codec. I have abosolutely no problems whatsoever. However, all my 720's are very efficiently compressed using my own settings with max bitrates not usually exceeding any more than 4,500kbps.
Sungsonic is supposed to be optimized for video and audio. But not sure if it is available / works on the P1000. I'm currently on a P3113.

I also had the same issue, I also love watching movies on my Tab, especially HD. I was on cm9 then shifted to cm10 parandroid. All of these custom ROMs have same issue with playing 720p and 1080p. The solution I still use is this:
1) delete all codecs and players, including MX player.
2) install bsplayer
3) then install mob player
4) then install MX player (don't install its codecs or the other players codecs)
5) go to MX player >>> settings>>> decoder>>> tick the hw+ decoder and at the bottom tick the deinterlace option
6) now try playing 720p or 1080p, in hw+ mode using MX player. If the player still lags you can use BS player, it handles HD quite well and slightly much better than MX player.
Hope this works for you. Please reply ASAP of the results...

Thanks for the suggestion. I ended up doing a full restock last night, and gave it all a go in the gb again, and am now back on the cm9, and it's working much better. One movie I stream as my test was always a bit juttery on cm10 variants, and also on gb is very good on cm9. And of course mx player will select hw in cm9 where it won't in the others.
Sometimes you just have to trial and error. Actually, everything is running a bit smoother than any cm10 I've used.

It's a fact that 1080p is VERY BAD on JB aosp based roms even with hw support, when they are played absolutly nice on GB rom !
About JB 4.1.2 not able to play fluently 1080p as stock GB samy does, one of our rom daddy explained somewhere that Samsung have some kind of proprietary codecs bought somewhere that aosp cannot have. So...
But I just tried ICS AOKP SGT7 milestone 6 (19/9/2012) and it decode 1080p flawlessly ! no difference with stock GB !
So what happen to JB 4.1 or 4.2 ? :cyclops:
edit : got a look at the 1080p' movies link used to Test videos for HW codec with MX, for example at the [ROM][CM10][JB][4.1.2][SGT7][P1000/N/L][PDroid][20121127] thread when guys complained about bad performance, and I discover that theses "reference' movies" were in fact both 800 or 816p ! along with a fanny readme that states "Original Video properties: Resolution: 1080p (1920x816) FPS: 23.976 (NTSC)"
So I think that many dev' validation test could have been badly abused that way with something near 720p !
It could be nice that our "old" 1080p mkv could stay running and streaming over our tab ... in JellyBean kernels & roms ad hoc !
Please ...
Thx

[Q] Can Xperia Z handle 10-bit video ?

I have galaxy S3 and it can only handle 10-bit video @ 480p
However, 720p 10-bit videos runs slow and laggy.
I wonder if Xperia Z can handle it without any slowdowns. Can some here test it ?

I should be able to answer your question in one hour. Stay tuned!
EDIT:
Unfortunately, when I tried to playback 720p 10bit video standard video player refused to play it and mxplayer opened it in software mode, refusing to use the H/W and H/W+ modes. In software mode I'd say it is watchable but is not perfectly smooth.

played a 10bit mkv through standard player, no lagg, smooth, while this was lagging using stock rom.. im now on tuddzrom , not sure if that fixed it lol but smooth nonetheless

Ok thanks guys
Galaxy S4 is supposed to have faster CPU than Xperia Z , so hope it will play it 10-bit 720p video smoothly.

5.1 channel mkv?
Guys,
On my Note II i can play 1080p mkv no problem, but the DDS (dolby digital 5.1) audio will not play.
I am switching to Z on Monday and am wondering if the 5.1 audio plays on mkv formats as well. Could u check that?
THanks!

1080p FLAC works flawless depending on the bitrate
720p no problems at all
Problem comes with 10bit. I think we all know that we want to watch our anime along the way. Most episodes are Hi10p.
I am not sure but how different is the Nexus 7 CPU against the Xperia Z? I can use the HW and HW+ decoder for 10bit episodes and they run smooth. But somehow the XZ refuses to use the HW/HW+ decoder. Might be, cause it's still new? No real HW support from MXPlayer yet?
I have no idea tbh.

Use MX Player's latest Test Build from here : https://sites.google.com/site/mxvpen/translation/test-build
It's a huge improvement.
Now my XZ (on 4.2.2 official ROM) can play 720p 10 bit anime very well

I guess 10 bit 1080p is asking too much :laugh:

If we talk about Xperia Z hardware capabilities to decode 10-bit encoded video, the answer is no, it will never allow it. Currently there isn't any smartphone being able to decode 10-bit enconding.
On the other side, software decoding is based on how well the algorithm is developed rather than the device itself. It's pure CPU processing power + how optimized in the algorithm so that might change with time. And from what I've seen reading this post MX video player is working on it.

I don't care if it's only software decoding. Even on PC, 10 bit video can't be played with hardware acceleration, right? (CMIIW) ^_^
