Same problem like in 8.6.0 verison like old one

[streki]

I try this version of VLC. On my IPTV UDP multicast stream doesnt play audio. Video codec is H264 /audio mp4a . Is it so me possible codecs for best function of VLC?

I was save raw format of problematic stream to /H264 video mp4a no audio play - raw/ directory of ftp server. Thanks for help.

Raw h.264 was not designed to be played in its raw state and very few players do this. While recently FPS is encoded (assuming you have selected this option during the encoding) most players do not read it and literally no Muxers read it. Also in this raw state there can be no audio because there is no container. Streaming this can be a real issue when there is no timing info...

Same problem here. There's no audio on UDP Multicast IPTV. I've uploaded some seconds of the stream to:
ftp://streams.videolan.org/incoming/No% ... kom%20IPTV

Here is what vlc 0.8.6 says:

Any fix would be very appreciated.

Please note the error:

ffmpeg warning: MBAFF + spatial direct mode is not implemented

This is an ffmpeg generated error for a feature that is not there.

But believe me: Very sporadic - I would say in 1 of 20 times the same stream is started - the audio is okay! So, where is the problem exactly? Is there any possibility to remove ffmpeg and use a h264-lib directly for decoding? Or how can I get the latest ffmpeg-lib for vlc to test, if this works?

When I save the stream as MPEG TS and play from Harddisk, then the audio is ok, but the the error messages above don't disappear...

I've uploaded the mpeg_ts-Stream to ftp://streams.videolan.org/incoming/No% ... kom%20IPTV

When you change the container you are not changing the format and the error will still be there. But this error really does not have anything to do with the audio of which nothing is mentioned in your posts. Considering the video is NOT working correctly, because the feature is not implemented, could be effecting the audio interleave decoding. This may also account for the sporadic behavior. The interleaving is changed when you change the container.

Re-compile VLC for your Operating system using the latest FFmpeg source code before testing. Libraries are only updated when VLC is re-compiled.

Same problem here. There's no audio on UDP Multicast IPTV.

See my workaround here:

Ya! I saw it and don't particularly think it's a good work round as the video issue remains.
