XVid codec

Yesturday I downloaded from Market YXFlash app, which is a kind of codec for XVid and a few more video formats. My question - if mobilesoft done it, I mean comiped xvid codec for arm on Android, can you - Android hackers do the same and publish here? I would like to say, that YXFlash works fine on my N1.

That would be amazing! Someone has gotta know how

Unfortunatelly I do not know C-family languages at all, so I can not do it my self... I was very sorry of xvid codecs lack in G1, but I understanded that is result of G1 processor limit (MSM7201A), which doesn't support this codec. According to QSD8250 specyfication - it should be possible to do it - to create codec (for coding and encoding) in other formats then h.264.

my TPRO can play divx with coreplayer and tcpmp with msm7201A so its not do with the processor.

Yes, you are right, because I read that mentioned app works also on G1. I think, that thanks Snapdragon support divix/xvid playback should be smoother and faster and not so processor-power consuming (read battery-saving).

This is a pointless discussion.
The codec (enCOder-DECoder) is HARDWARE -- built into the same package as the CPU.
XVid is more properly known as H.263, which is FULLY SUPPORTED by the hardware codec, not only for GN1, but also for OTHER android phones all the way back to and including DREAM.
There are two things *definitely* standing in the way of just playing back an "xvid" video file: 1) Demuxer applicable to the container that the video is contained in, i.e. ogm, avi, mkv, etc., 2) FOURCC -- when using the xvid h.263 encoder, the fourcc will be (incorrectly) set to "XVID" when it *should* be set to "H263". Regardless of this, the chip doesn't care what the FOURCC is, just the media player (which needs to know the stream details in order to set up the decoder chip).
There can be other issues involved in playing back the file... bitrate/resolution exceeding codec limits, audio encoding incompatible, etc.

On a side note the excellent core player should be coming out on android soon enough,they seem to be in testing stages now.

I would be shocked if coreplayer was out for android this year. The s60v5 version has been "in the works" for over a year now I think, and porting from s60v3 should be cake. Coreplayer 2.0 is the DNF of mobile apps

They didnt do the iphone because they were shutdown by Apple.
They keep posting progress including screenshots for Android.

They already got sound and UI done, hinted that progress was going better than expected. As for YXFlash... it sucks for certain videos and after 2 minutes, BOOM! tough actin tinactin!

Xvid/Dvix Play back with stock rom?

We all know Divx/Xvid is capable with the TouchWiz, but is it the TouchWiz that allows playback or is there an underlying app that will allow Divx/Xvid to play?
Most of us are considering rooting and either loading the International Rom if its better or running some kind of stock rom to rid TouchWiz unless of course its not as laggy as reports have said.
I'm really digging on the idea of being able to play Divx/Xvid.

The T-Mobile Vibrant plays all the same videos the international versions do, no change to the video player at all. I've been watching 720p MKVs and various divx/xvid files on mine without issue!

I think the OP is asking if it plays those files without touchwiz being present or active?

yes you can disable the touchwiz and still have video playback in all formats...

Yeah thats what I was interested in. If we mod would it change the ability to play movies.

Have any if you try the divx video yet? It won't play on my vibrant for some reason. I was able to play 720p mkv,mp4 but not divx.
Sent from my SGH-T959 using XDA App

I didn't even know it had mkv/divx/xvid playback, this makes me happy lol..

I hope it does. All mose all my Vids are Xvids and Divx files. Just ordered mine so I couldnt' even tell.

do you just play the 4gig mkv or do you compress it somehow? I want to put some more videos on but dont know what size to compress them to/what program is best for my vibrant's resolution.

There isn't a file size limit persay, but it seems the Vibrant will reject any videos with resolutions higher than 1280x720. E.M. Total Video Converter HD seems to be best so far in terms of quality and conversion success rates, but if you're looking for freeware, Handbrake works very well. Set the profile to iPhone, and make sure the video resolution is 800x480 or less.

The international rom should be able to play the xvid/mkv video but if you flash on some other Rom (e.g. AOSP Froyo, etc) then it will lose the ability to play them unless someone figure out how to port the ability into the other Rom.

My vibrant wont divx, but play 720mkv perfectly. Yxplayer play divx but very choppy.

Didn't engadget somehow play a 1080p video on the Galaxy S when they compared it with the iphone? or do you mean the divx can;t be more then 720p?
And as for the rom thing...The video should be hardware decoded..so as long as the drivers are portable it would be possible on any galaxy s regardless the rom..or at least that is my guess...

Why the hell would they put specific hardware decoders in the phone for divx support? I would assume they just included the codec support with the stock rom. I seriously doubt that you can throw any rom in there and immediately playback divx video.
I'm not sure what you mean by asking if engadget played a 1080p movie on the galaxy S. Do you mean that they used a 1080p video and the phone auto-scaled it down to 800x480?

I remember reading it has the video decoder built into the Hummingbird GPU..but I don't remember where...let me see if I can find the source.
Edit: never mind the 1080p..I went searching for that article and they modified it since I read it to say they did it via youtube 1080p setting on the app >.>..but they dont even know if it was 1080p or 720p either..sigh

I went searching and found a review that states "Dedicated Graphics Hardware With Divx decoding" as a pro for getting the phone. I think they combined two things here (the Power VR gpu and the software support for divx). I see how it could be read to imply that the divx support is hardware based, but an earlier part of the article indicates that the divx codec support is built into the video player software.
Here's the article: http://pocketnow.com/hardware-1/samsung-galaxy-s-gt-i9000-review
This is really a situation for Occam's razor. Would they go to all the expense of adding hardware divx support to the cpu design or would they just use already existing software solutions that cost almost nothing to implement? The press release from last year revealing the hummingbird doesn't have any mention of it. http://www.samsung.com/global/business/semiconductor/newsView.do?news_id=1030

That said Divx Decode was part of the ATI hardware decoder..at least in the 4XXX series
As for samsung''s reason to do this...we have to remember that the Hummingbird was meant to be scalable so they can use it for tablets..thus having it natively support the large array of formats is key.

Just got the Vibrant and noticed that it would not play some AVI files (simple TV show low res). had to DL rock player to play those files.Also had an mp4 play in stock video player but would not play the sound and in Rock player tried to play the sound but was garbled.
So not sure what the full support is and wondering if we just need to get a nice media player.

Getting around the ac3 limitation

Try VitalPlayer from the market. I had no issues playing files that were blocked by the 101's native video player for lack of ac3 support. Also could play 720p.
Just fyi for all.
(I am not affiliated with the app or the developer).

so does it support hardware acceleration?

Well, if there are hardware codecs, it uses it... else it uses software codecs... so ac3 is most likely decoded using the software codecs

have been testing this for a week now and it seems to work very well

Thanks for the heads up. But it does choke on the 720p files!

It doesnt choke on 720p for me. I have the Shrek series and they play well.
Also another benefit is that it works well with the OC kernel on UrukDroid. Other video players including the Archos' native one had a lag between audio and video on OC. This one doesnt.

[Q] Chances for better hardware-accelerated media playing?

Hi Iconia-Lovers,
I really love my Tab for web-browsing and gaming, but you have to admit it sucks at video playing. MP4 and 3GP are crappy formats that are hardly used in RL und converting your whole video and movie collection isn't a real option.
I had have an Archos A70 which plays even 1080p MKV flawless with a single core 1GHZ CPU, but relies on an additional decoding chip if i get this right.
In theory, the Tegra 2 has more than enough power to play 1080p files, right?
I already tried like 6 different media players but all of them weren't able to play 720p mkvs nice and even non-HD-avi-files felt a little slowed-down.
So can we hope for a hardware-accelerated media player that enables alle the joy of moving pictures for us? Will possibly acer itself help us out on this issue? What are Samsung and Motorola doing on their Gingerbread tablets to enable nice media playing?
Hoping for a better tomorrow
Cheers

you sure about that?? my 101 throws a fit with 1080p mkv videos and both use the the firmware.

Tried VPlayer? it costs like $4/ £2.30 but it can play practically all standards, not sure how it fares for 1080p tho.
I had it playing .avi and .mkv fine though.
Vplayer--
Video formats: divx/xvid, wmv, m4v, flv, rmvb, avi, mkv, mov, mp4, 3gp, ts, tp...
Streaming: http, rtsp, mms and m3u(apple http stream, m3u8)

I use UPnPlay (network streaming) along with MoboPlayer and it has played everything i have on my NAS very well.

Also I know Rockplayer gives you the option of hardware/software decoding so you may want to give that a try if you haven't already. There is a free version.

Both moboplayer and rock player are useless for my 720p and 1080p videos... total stutterfest, but that's a known thing for tegra devices on 3.0...

Hmmm... I use moboplayer, and every 720 did I've tried has been great! I haven't tried any 1080p vids though.

tested 1080 quality....the videos lag and the audio missing....
hope acer will figure it out....

Avatar & 10,000 B.C. in 1080P using UPnPlay & MoboPlayer streamed from my WD NAS, looks great. No lagging at all.

I have been trying all the suggested encoders to get smooth playback for film material as 60/50hz works fine. I maybe more sensative to it than others as I tent to look for it on moving objects. But I got it to replace a media player too.
I tried the script posted in another thread with good results but the jump is still there.
Bought DVD Catalist 4 with same results.
Freemake with custom profile same again.
Handbreak I find too slow but I read it works but can't verify it.
Any Video Converter Pro with xoom profile WORKS - it has very little judder but having to strip the subtitles out of the MKV every time is a real pain ( Anyone know how to disable them ) and it's too expensive anyway.
Trying to edit DVD Catalist 4 profile now but no success yet
Oh and I tried Vplayer , Rockplayer , Moboplayer and any others I could find
Hope my two weeks at this helps somone else out.

@RaveOn911
With any problem, you need to find its parameters. Only a handful of people notice the "micro-stutter" deal, so it's either a user sensitivity issue, or a tablet-centric issue (which could be hardware or software, user-caused or device defect).
Ask somebody to watch a video clip on your tablet, and ask them if they see anything wrong with playback. Don't tell him beforehand about "micro-stutter", as you don't want to bias his observation.
If he notices the stutter, it's your tablet. If he doesn't, it's you.
If the first, then bring a video clip on a uSD card into a store and try it on other tablets (hopefully with same or similar make as yours). If it doesn't happen on other tabs, then replace your tab. If it happens on every other tab, then again it's you.
If you have heightened sensitivity, then there may be params that can alleviate the issue. The default interleave for MP4Box is 0.5s. You can reduce this interleave, eg
MP4Box -inter 250 -add infile.mp4 -new outfile.mp4
(or)
MP4Box -tight -add infile.mp4 -new outfile.mp4
MP4Box works on MP4 only. Given that MKVs can only play in software mode currently on Teg2 tabs, it's a fool's errand to play MKV and claim that they don't play smoothly. Avail of the native support.

Mobo Player plays my mkv and xvid/divx AVI's just fine. I'm no codec/encoding expert, but from what I've read it's worth re-encoding some of the files to a more manageable bitrate for both audio and video and maybe dump the 5.1 or AC3 audio. I haven't looked at every file I've played, but a couple that would choke on my Win7 Asus netbook, I re-encoded with Handbrake. They still look and sound great.

I understood that that's the whole point the OP was trying to make: he wishes that someone makes a video player application that can handle MKVs via the hardware decoder. It's not a bad thing to wish for, either; it would provide better performance and hardware playback uses less battery, too.
The question remains: is it possible? As far as I know, the chip itself doesn't get relayed anything more than the actual video stream inside the file, regardless of the container, and thus an app should be able to do exactly that. But since I don't know anything about Android internals are applications given any such access?
My N900 phone uses regular GStreamer stack and thus you can demux anything you want and supply the video stream to the hardware decoder. As long as it's H.264 normal profile and not too high a resolution it'll play, regardless of the originating container.

There's nothing wrong with wishing, but until it happens, we have to use what we've got. For HC, for now that means MP4 for native support.
3.1 thus far has been worse than 2.x insofar as multimedia, probably because vendors have had 2.x for much longer, and were able to add enhanced support. A good case in point is the Samsung GalTab 7 vs the GalTab 10.1. The 7, released last year, can play MKV. The new 10.1 can't. Ditto for all the "my old phone can play MKV, why can't my tablet" complaints. It is what it is.
From all indications, HC was and is a rush job. It had to be pushed out the door because of competition from the iPad. I think the prospective buyer should understand that s/he is buying into a beta, and temper his expectations accordingly. Android has high potential, but now isn't then.
I've written a script that does fast remux/convert to MP4. A straight remux takes a few minutes, and it can process batch. It's a more productive route than wishing for a HW-accel player to come along.

I suppose that's a matter of viewpoint.
I took a look at the MediaPlayer class in Google's APIs and it seems to me that it should be fairly straightforward to demux the MKV file in software on-the-fly, create named pipe with mkfifo and feed the MediaPlayer class the raw video stream via that. Just throw a simple GUI on top of that and you have a rudimentary video player capable of playing MKV files with hardware accelerated video.
I'll try it out once I receive my tablet, was planning to learn Android programming anyways.
PS. Bah, doesn't allow me to post links yet :/

Lagfree playing of .mkv 720p/1080p source

Hi folks,
Is there any posibility of a lagfree playing of those videos ?
It sucks watching Videos with less than 20fps...

3.1 is supposed to improve playback... just no idea if it will improve 720/1080p playback
Sent from my A500 using Tapatalk

I use Handbrake and imported these setting I found on the net.
https://sites.google.com/site/theiveryinc/a500files
That Google site is mine.
Converts all my 720p.mkv files perfectly, the only issue is the files are big, 2-4 GB, but the quality is outstanding. They even play on 'Movies' which darkens the navigation bar.

i was looking for something like this so many times before, but I never found a stable movie app. On my Samsung Galaxy S II however, it's no problem at all. And that's a freaking phone man! But it's no wonder the hole system is so fast. It makes my newly aquired Iconia looking really sluggish and outdated :-( I don't know if I gonna keep this tablet or gonna look my movies on a 4.3" screen...

I asked Acer customer support whether they're ever going to support additional formats and they replied that they won't ever add support for MKV and can't comment on the rest. So official support for MKV is out the window.

Mkv isn't a video format, it's a container. It's just that most mkv's don't contain only baseline h.264, which is the only supported video format currently. The most benefit would come from adding support for main or high profile h.264

I know, it still doesn't help at all if the video player application or framework don't support the container format. I personally love MKV, it's handy to slap in two different audio tracks and subtitles in English, Finnish and the hearing-impaired version, plus any metadata about the movie itself. No need to hassle with several files then.

Indeed. I tried transcoding a 1080p movie to 720p in constant quality mode, both in baseline and high profile modes, and while the quality was the same the high profile one used a lot less storage space. With storage space being rather scarse on mobile devices....
Well, we can only hope. But I don't know if the DSP is beefy enough to decode high profile or if it can be re-programmed to support it. Some DSPs are hardcoded and can't be used for anything other than what they already do when shipped. I don't know anything about Tegra 2 internals so I don't know what to expect.

I use 3.1 atm, but there is no mentionable ddifference to 3.0.1

The nVIDIA Tegra 2 250 is fully able to hardware decode:
H.264
VC-1 AP
MPEG2
MPEG-4
DivX 4/5
XviD HT
H.263
Theora
VP8
WMV
Sorenson Spark
Real Video
VP6
and encode:
H.264
MPEG4
H.263
VP8
And this is for 1080p both enc/dec
Why ACER can't (won't) support them is beyond me! Even my Single Core 7" Samsung Galaxy TAB can play all 1080p videos I have thrown at it!
And here is the full spec of the Tegra 2 250 Link!

Is it maybe because of that, that I play these videos from my USB-HDD?

You can always copy one of them to the TAB and see if there is any change ( I doubt it)

Using a OLD 60gb usb hdd (literally 8 years old)
And it does not seem to matter - even with the low speed of an old external drive I have no issues playing video from it.
.Mkv -- Regardless of where it is stored is not going to work on the Iconia right now - i don't think there is anything anyone can do or change to fix that right now - the system will not?/can not? use the hardware decoder on mkv files - and software decoding, even for a low bit rate video file is always going to suck.
Hopefully 3.1 will improve our video performance - but I find it a very simple matter to just transcode a video file if the only source I have handy is mkv. Plenty of great and free tools that make the process pretty darn easy. I watch a lot of movies/TV on my a500 - and get a great experience as long as I don't throw .mkv files at it.

With regard to the container format vs video format thing, I'm under the impression that container format support can be added by an app - so even if Acer never support mkv in the default player, if they do add hardware high profile h.264, then other apps should be able to play an mkv that contains high profile h.264 with hardware acceleration.

Hopefully 3.1 will improve our video performance - but I find it a very simple matter to just transcode a video file if the only source I have handy is mkv. Plenty of great and free tools that make the process pretty darn easy. I watch a lot of movies/TV on my a500 - and get a great experience as long as I don't throw .mkv files at it.

From playing around with PRIMEE, mkv containers are split appropriately and if the video format is supported hardware decoding works. The problem is that there is no support for AC3 therefore majority of compatible MKVs will play very well but have no sound.
Unfortunately once software encoding is enabled we are back to the same stuttery playback issues.
I personally don't believe it's Acers' job to add playback compatibility, I personally believe it should be built into Honeycomb as a baseline. Honeycomb is a tablet OS and as such should be expected to play popular video and audio. codecs. Saying that, if manufacturers did add additional codec support it would be a solid competitive edge.

Use mobo player.

Have you read any of the thread, running moboplayer doesn't help, as I mentioned above as soon as you enable software decoding HD MKVs start to get choppy.

Ah, that's good to know, so with a baseline h.264 payload an MKV will play fine on stock?
I think it probably IS Acer's job to add codec support, frankly. At the end of the day we're talking about hardware acceleration, and Android provides the software framework for that to work, and it's up to the hardware vendor to make it work with their specific hardware.
Frankly I think Nvidia should be doing it though - it'd do wonders for Tegra 2 sales if they offered up code to support hardware acceleration for their platform on Android.

I guess you didn't really do your research on video playback on Honeycomb tablets, did you?
You can not blame Acer for poor HD playback when, frankly, this is a Google/nVidia issue. Currently no 10" Honeycomb tablet can playback high profile encoded HD vides--smoothly, if at all--without reconverting said movies.
There may or may not be a *real* fix in the future (quad core Tegras are right around the corner, so...), only time will tell.

The nVIDIA Tegra 2 250 is fully able to hardware decode:
H.264
VC-1 AP
MPEG2
MPEG-4
DivX 4/5
XviD HT
H.263
Theora
VP8
WMV
Sorenson Spark
Real Video
VP6
and encode:
H.264
MPEG4
H.263
VP8
And this is for 1080p both enc/dec
Why ACER can't (won't) support them is beyond me! Even my Single Core 7" Samsung Galaxy TAB can play all 1080p videos I have thrown at it!
And here is the full spec of the Tegra 2 250 Link!

I bought an ACER device so I'll blame them! Problem here is that the Tegra 2 chip is capable to decode and encode the formats at 1080p without problems! The fact that Google still hasn't taken advantage of this feature doesn't mean that ACER couldn't!! To back my words here is an example:
Samsung! The Galaxy S and Galaxy TAB (7") they have much superior video codec support! I'm playing 1080p movies just perfectly on the Galaxy TAB. Samsung have invested in codec support and optimized it for the platform (both Hardware and Software) The Hummingbird CPU is Single Core! So why can't ACER do it? Maybe because they never did something like this before? Maybe because the have done only the hardware till now and they don't have the programmers that can pull this of? Ones the managers at ACER understand that selling thees devices without enhancing the base that Google provides won't cut it, I think we will have a very good device (not that it isn't good now but...)

Guess you'll have to "blame" every single manufacturer out there who have a Honeycomb tablet out too, then.

So does the Samsung 10.1 play 1080p videos smoothly?
From what I've been reading.. no. Frankly, watching a 1080p on a 10" tablet is pointless (which is what I'm assuming you're crying about). If 720p isn't "good enough" on a 10" tablet, well, then, time to buy a 17" laptop.
