Is there any manually option that need to be activated ?

Can't remember if i touched something, i think it should be auto. That's under 0.76, btw.

@ktadd

Thanks for providing a guide on how to do it from the GUI.

Hmm, you should see the different audio streams, like this:

That's a dual-audio video, so either switch the audio stream from the DvP's context-menu, or fix it by using FFmpeg:

ffmpeg -i KRO_01.avi -map 0:0 -map 0:1 -vcodec copy -acodec copy KRO_01-single_audio.avi

@K-L

Yeah, but obviously due DVP does not uses this lib to handle containers, so it has nothing to do with the lib basically.

Definitely both you are wrong

He's asking for codecs, and indeed DvP does *not* needs to be updated for more of them to be supported/playable.

If we talk about containers, that's another history though. If you have a 90s MPEG-1 stream embed into a MKV file DvP will not be able to play it and therefore it'll need to be updated, but just to support new containers such as MP4 or MKV.

@Trixie

53.1 had some tricks enabled which are now disabled by default since it might cause issues on certain cases.

You can try to enable them with:

shell> setenv AVCODEC_TRICKS 1

Note however, this may or may not is the reason, there were new API functions on the last core which to make them backward compatible with our lib we had to implement some wrapper on top of it.

Hello,

As announced on the bounty page, the final 53.x version has been uploaded to os4depot.

$VER: avcodec.library 53.611 Build #9126 (31.05.2012)

This version is based on FFmpeg 0.10.3 "Freedom" which was released on 2012-05-06. It is the latest stable FFmpeg release from the 0.10 release branch, which was cut from master on 2012-01-26. Amongst lots of other changes, it includes all changes from ffmpeg-mt, libav master of 2012-01-26, libav 0.8.2 as of 2012-05-06.

Further details on the Readme file included in the archive.

http://os4depot.net/?function=showfile&file=video/misc/avcodec.lha

All reported issues should be fixed, except one: there are problems with videos using dual-audio streams. However, anybody who encounters this problem can get rid of it by switching the audio stream being used from the DvP's context-menu.

If you found other problems, don't hesitate to report them. Thank you.

Where can i get the latest version?

I'll CC it to you on next branch.

In fact, i might be in need of some 460 and x1k users to test our latest build(s), in case someone else is interested.

I saw several reports about DVD colour problems, and I assumed that this had been reported to the library's developers...

Yes, and the issue got fixed several weeks ago.

Is there a PPC440ep optimised version?

That's something we tried, but it didn't performed any better than a normal/generic build, don't ask me why..

Something else weird we've noticed, Cobra was reporting the new lib performing better (compared to 51.52) on his sam440ep 667 than what i was noticing here on a 440ep-Flex - and that was recently confirmed by K-L as well, once again... don't ask me why - I always wondered if there was something wrong with the compiler i'm using (GCC 4.2.4 (adtools build 20100512))

Maybe you guys could help me to perform some quick benchmark test using the following tool:

http://amiga.sourceforge.net/temp/byte_test.lha

Here are my results under SAM440ep-Flex:

2.AmigaOS4:> byte_test
7856
7856
78563412
78563412
took 1.6496
took 2.0652
took 2.0662
took 1.6545

Feel free to test it under your machines and post back your results (if you want run the tool several times and pick the one which performs better..)

this one was converted from a 60 FPS MP4 file that MPlayer couldn't read even on my G4 1,26 Ghz

That explains everything

Quote:

I've tested the latest release and it works flawlessly

Nice, i was afraid i may made other videos noticeably slow.. (due the checks for used fps..)

BTW, forgot to mention something else implemented on that version is the use of a new AVCODEC_LOWRES environment variable which when set to 1 should halve the size of the video, as a result you can watch that 60fps video with no frameskip but at 320x240 therefore..

Anybody familiar with ffmpeg should be aware already of that "lowres" option and how it works/use - I didn't tested it yet but theoretically it should make possible watching eg 720p movies on SAMs.. ;)

@Slayer

If you don't mind it could be nice if you at least post the specs of such movies you're talking about - and send me your email for the altivec version.

I gave Mrodfr a link to download this video.

Nice find the video you pointed out - that's a 60fps one and fwiw i wasn't able to properly play it using neither MPC, VLC, nor MPlayer under Win7

I'd be interested on testing more of these if you have.

For now i've implemented some trick which should make it possible to play them at the cost of quality, as long the hardware isn't powerful enough.

http://amiga.sourceforge.net/temp/avcodec-53.1.39C03.7z

That's a debug-only version, which should fix the AC3 issue as well, test it yourself and let me know if everything is fine/acceptable.. if so i'll upload a new package to os4depot.

playing MPG files, sound is overboosted and saturates.

That's the new AC3 decoder, which initially was too quiet (much more than the old a52 used on 51.52) and i make it louder by using a hardcoded value... Noted and i'll fix it for the next version.

Quote:

will Altivec be supported in the near future.

Sure. I just didn't played with this yet as i'm not able to test it myself.. If you want to test it yourself i can send you the lib before it gets released.

switched to the debug version now and then i restarted the same video, for now no new crash to report

Hmm, you may want to check again if you can reproduce the issue by using the non-debug version, in case there's something wrong with the debug version... (that's why we request a link to the movie/clip, to do such tests ourselves without annoying end-users

@trixie

Quote:

could avcodec.library be also used to just extract the audio track from the video file?

The lib can be used for this purpose, of course. However, the current API may does not contains every handy function one would expect to achieve it.

If Mplayer can't use this library,

Who said it "can't"? it's just that it does not seems to use it.

Quote:

and DvPlayer cannot use the additional formats without being updated,

DvPlayer needs to understand the containers, once it does any codec should be playable. For example 53.1 can play eg IV50 or WMVA which wasn't possible previously.

Quote:

where can we use this library?

Like with any other shared library, anybody is free to use it - it's up to the developer.
