can you give me the exact way to reproduce it ? (and perhaps also upload a sample file you want to transcode) also I'll need the output vlc gives when ran with : vlc -vv --reset-plugins-cache
If you are not able to find test video files on the net, let met provide you those: http://orange.blender.org/download http://www.plumiferos.com/html/descargas-en.php Let us use http://dl.freecontrib.org/elephantdream/elephantsdream-480-h264-st-aac.mov. In the preferences, stream outputs, setup the MPEG-TS muxer to use 68 as the video pid, 69 as the audio PID. In open file (not the quick one), open the above video file and configure the stream/save advanced options to stream locally(127.0.0.1:1234) as TS over UDP with mp2v (3072 as the bitrate) and mp3 transcode, which forges the following stream output MRL: :sout=#transcode{vcodec=mp2v,vb=3072,scale=1,acodec=mp3,ab=192,channels=2}:duplicate{dst=std{access=udp,mux=ts,dst=127.0.0.1:1234}} click ok (2 times for the 2 dialog boxes) buttons to start streaming out the video file In another instance of vlc or a "mplayer udp://127.0.0.1:1234", try to visualize the video (I get only audio most of the time, and no video). vlc output for this procedure on my system attached to this report.

thanks for the explanations. I can reproduce your problem, and I see in your logs (and in mines): [00000481] ffmpeg encoder warning: MPEG1/2 does not support 24/11 fps (mpeg2video@0x137b770) and in fact, when I change the video codec to, say, mp4v, I get the video. It seems ffmpeg doesnt want to encode to mpeg2 with this framerate. Perhaps you should try with another codec. Did it fail the same way with 0.8.6c and ffmpeg 0.4.9_p20070616 ? (not -r2 nor -r1 as it will break 0.8.6c's ffmpeg support)
You got it working with the mpg4v? Because when using the same file with the mpg4v encoder I get in the verbose log: ffmpeg encoder warning: timebase not supported by mpeg 4 standard (mpeg4@0x8441d40) I tried to TS stream without transcode, and I get video and audio, but the picture is reduced to a very small 256x144 from 1024x576.
actually yes, it streams correctly, I get lot of output but it works with the following sout command: :sout=#transcode{vcodec=mp4v,vb=1024,scale=1,acodec=mp3,ab=192,channels=2}:duplicate{dst=std{access=udp,mux=ts,dst=127.0.0.1:1234}} I get this output (stripping irrelevant stuff): [00000360] stream_out_transcode private debug: late picture skipped (59178) [00000360] stream_out_transcode private debug: decoder aspect is 432000:432000 [00000360] stream_out_transcode private debug: source pixel aspect is 0.562500:1 [00000360] stream_out_transcode private debug: scaled pixel aspect is 0.562500:1 [00000360] stream_out_transcode private debug: source 480x270, crop 480x270, destination 480x270, padding 480x270 [00000360] stream_out_transcode private debug: encoder aspect is 432000:432000 [00000376] main encoder debug: looking for encoder module: 10 candidates [00000376] ffmpeg encoder debug: libavcodec already initialized [00000376] ffmpeg encoder debug: found encoder MPEG-4 Video [00000376] main encoder debug: using encoder module "ffmpeg" [00000362] stream_out_duplicate private debug: duplicated a new stream codec=mp4v (es=0 group=0) but not the error you mentioned :/ what is you ffmpeg version ? perhaps transcode downscaling is due to some settings left in your preferences. could you try with an empty ~/.config/vlc ? (also empty ~/.vlc but it shouldnt be used anymore afaik)
I still get: ffmpeg encoder warning: timebase not supported by mpeg 4 standard (mpeg4@0x84ac270) [00000332] ffmpeg encoder error: cannot open encoder [00000316] stream_out_transcode private error: cannot find encoder ((null)) So it's a limitation of the ffmpeg encoder. Removing the .config/vlc directory made the pass-through work fine. My ffmpeg version is media-video/ffmpeg-0.4.9_p20070616-r2

I need to test it with a frame rate adapter in order to provide proper frame rate to the mpeg4(2) encoder (do not know if it's possible with transcode). I will run some more tests and will fix the bug if ok.
media-video/vlc-0.9.0_alpha20080128 is broken. I cannot even stream a file anymore(UDP,TS 127.0.0.1:1234), it hangs. And playback is defective (got cracks in the sound).

I've always failed to understand what's wrong here, so any help is very welcome). However I can stream with the command: vlc -vvv elephantsdream-480-h264-st-aac.mov --sout '#transcode{vcodec=mp4v,vb=3072,scale=1,acodec=mp3,ab=192,channels=2}:standard{access=udp,mux=ts,dst=localhost:8080}' using mp2v still gives errors about the encoder. > And playback is defective (got cracks > in the sound). hmmm here its fine. Can you please check with latest snapshots ? As it's dev. version it's very possible some bugs were present and have been fixed.

I get this with _beta3: [00000501] avcodec encoder debug: libavcodec already initialized [00000501] avcodec encoder warning: MPEG1/2 does not support 24/11 fps (mpeg2video@0x1355f60) [00000501] avcodec encoder error: cannot open encoder This seems more a ffmpeg / mpeg1/2 limitation rather than a vlc error. Can we eventually close this bug ? (not sure what would be the resolution considering how hard it has been :p )
