The xonar driver would even refuse PCM formats in wasapi mode

I really have to take some time to create this tool that will scan all the accepted types

For now, only radeon 5xxx owners can help

Once the stream will be working, we will focus on other cards

that tool would probably save everyone a lot of time (we could check which drivers support what, to speed up testing)

I have a question with regards to the "FFMPEG-MT" H.264 decoder,
Is there any downside to using this decoder on a single-core system (as compared to the libavcodec)? Any compatibility issues or degraded performance?

Ok, I definitely will bow out for now

Hi guys...
Possible bug encountered in libavcodec for MPEG2 stream...
Works fine when changed to libmpeg2...
rev3098 works fine...
IIRC it broke since rev3099, FFMpeg update..?
Any confirmation..?
Thanx in advance...

clsid · 18th October 2009, 14:03

@Blight
Performance with 1 thread should be the same as regular libavcodec. I haven't done any recent comparisons, but you can benchmark it yourself if you want numbers. Search the forum for Haali's "timecodec" tool.

@EpsilonX
What exactly is the bug? MPEG-2 playback is working fine here with libavcodec. You might got a bad build.

SamuriHL · 18th October 2009, 15:11

@albain:

No go. It changes the receiver to PCM mode, no audio.

I've tried a couple of builds since 3099, at least 5 builds...
From here and xvidvideo.ru...
It only happen using libavcodec as MPEG2 decoder, reverting to 3908 fix it...
Sorry for the lack of detail in the previous post...
Tried it with MPEG2 files and it's working fine...
The problem only appear when it's used for DVD decoding...
Since my settings for DVD and MPEG2 are the same, a conflict with DVD Navigator maybe..?

Just for educational purposes, I did a little benchmark using ffmpeg-mt compiled with -march=core2. Here are the results:

(My specs are in my signature)

*User: 4s, kernel: 0s, total: 4s, real: 17s, fps: 104.1, dfps: 29.2

The difference is not big, especially for the 2160p video. Of course DivX H.264 decoder is the winner in both videos.
For those interested, here is the 3108 core2 build while normal builds are here.

I'm having the same problem with AVC (libavcodec),
while I try to exit the playing application, it crashes,
it only happen with libavcodec (not with ffmpeg-MT), and with rev. 3099 and up, no problem with rev. 3098.

OK then, I will come to plan B, which is harder and longer to put in place....

Alright, man. Good luck. I'm sure you'll get it.

I have the same issue.

LoRd_MuldeR · 18th October 2009, 21:09

Similar problem here with latest ffdshow build by clsid. DVBViewer will crash at application exit:
http://pastie.org/659774

Code:

The FFmpeg changes to w32thread.c must be buggy then. I don't have time to revert it now, maybe tomorrow, otherwise Tuesday.

Salut and Bon Courage

I can post now so i have tested with ATI 4350 and Xonar too. I have see longtime after that it must made on 5xxxx series.

So now when the light comes out with 5xxx.
I hope that it will work with 4xxx and Xonar

Encore merci

Thx,
Seb.

Merci pour les encouragements, il reste du boulot :-)

@Xonar owners
Can someone confirm me that with Total Media Theatre + a Xonar, you can play a M2TS file with a TrueHD streamin bitstream mode ?
I need to know this answer in order to go further

Thanks

No, you can't I'm afraid. You need to play a BD structure for bitstreaming to work at present.
