VLC 2.0.4, Windows, Transcoding to MPEG2 broken?

[bzbit]

I seem to be unable to transcode any media into MPEG2 using VLC 2.0.4. This command line worked on previous versions of VLC.
Now I get the error:

[mpeg2video @ 0177ab80] a vbv buffer size is needed, for encoding with a maximum bitrate
[034578f0] avcodec encoder error: cannot open encoder

[034578f0] main encoder error: Streaming / Transcoding failed
[034578f0] main encoder error: VLC could not open the encoder.
[0171e3c8] stream_out_transcode stream out error: cannot find video encoder (module:ffmpeg fourcc:mp2v). Take a look few lines earlier to see possible reason.
[0171e3c8] stream_out_transcode stream out error: cannot create video chain
[01785380] main decoder error: cannot create packetizer output (mp4v)

Using the command line:

"C:\Program Files\VideoLAN\VLC\vlc.exe" -I dummy --dummy-quiet --ffmpeg-hurry-up --no-loop --no-repeat --ffmpeg-skiploopfilter 4 --audio-language=any --start-time 0 --sout "#transcode{venc=ffmpeg,vcodec=mp2v,vb=7000,acodec=a52,ab=384,samplerate=48000,deinterlace}:std{access=file,mux=ts,dst="test.mpg"}" --sout-transcode-width 480 --sout-transcode-height 320 --sout-ffmpeg-keyint=3 "C:\Media\sample.avi" "vlc://quit"

I have tried adding in an option for vbv-bufsize like this 'venc=ffmpeg{vbv-bufsize=1600}' but that does not help. It also doesn't seem to matter if I use the ps muxer, change the audio or use a different kind of input file.

Any ideas what might be the problem?

I am having the same issue, running VLC 2.0.4 on a MAC.

Please run -vvv

Thanks for the reply, Jean-Baptiste

as requested, here is the output from -vvv, I hope this helps !

[Jean-Baptiste Kempf]

Yes. Try to change the --sout-ffmpeg-rc-buffer-size too

[bzbit]

Thank you, I can confirm that that flag works fine.

Unfortunately the command line I posted above crashes VLC once the flag is used but I'm pretty sure the problem is the same as this one:

viewtopic.php?f=14&t=105229

the a52 codec seems to have the same problem as the mp4a codec mentioned, however using the new flag and switching to mp2a for the audio works fine.

Thank you.

[Jean-Baptiste Kempf]

This is a separate issue, I think.

[bzbit]

Sorry for the long delay in a reply Jean-Baptiste, I had no power due to hurricane Sandy.

Would you like me to create a new issue for the a52 transcode crash with -vvv debug for it? Or would you like me to report it as a bug?

[Jean-Baptiste Kempf]

yes.

Hi all,
wonder whether the origin of the demux error I experienced when playing a DVD might be the same as the one described above.

Here is what I get after having played the DVD (Windows 7, VLC versions 2.0.4 and 2.0.5) flawlessly for ~1:11 h,
using the start command
vlc --file-logging -vvv

(to be honest, having learned how to switch on verbose logging in VLC, I restarted the DVD and jumped forward to the crashing point in the stream...
that's why there is a lot of 'main debug: Buffering xx%' messages in the log which I cut away....)

The crash itself is such that VLC closes the output window without any error messages at the front end.
However, a VLC file selector box showing the DVD drive entry remains open.

BTW:
Windows Media player shows a short disturbance with some block artifacts in the picture, but it manages to continue the movie.
A ONKYO DVD player attached to my TV just continues the movie without any artifacts.

In case this turns out to be ( or belong to) a completely different issue,
I would appreciate if the forum admin would just move my message to the appropriate thread or open a new one.

Regards
aqua
