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? |

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... |

@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.

@albain:
No go. It changes the receiver to PCM mode, no audio. http://pastebin.com/pastebin.php?dl=d73cc1bfe |

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..? |

Similar problem here with latest ffdshow build by clsid. DVBViewer will crash at application exit:
http://pastie.org/659774 Code:
Program received signal SIGSEGV, Segmentation fault. [Switching to thread 3684.0x12b0] 0x6fd844ff in thread_func@4 () from D:\ffdshow\libavcodec.dll

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