Bug Description

With luciole_0.8.4 (rev. 75) on Ubuntu Karmic.

Exporting as DV works, but both "divx/xvid (avi)" and "DVD (Mpeg2)" fail silently (the exported file is not generated). When this happens, i get the following output on the console:

--------------------------------------------------------------
Exception in thread Thread-4:
Traceback (most recent call last):

mencoder version 2:1.0rc3
ffmpeg version 5:0.5

Hi,

I not success yet to reproduce the problem.

Could you try the joined mencoder command
Put this file in <luciole_project_dir>/tmp/export

and launch it in a terminal.

Is the mencoder conversion runs corretly ?
Is line like :
Video stream: 671.042 kbit/s (83880 B/s) size: 268417 bytes 3.200 secs 80 frames
appears ?

This is the line processed by the aLine variable

Thks for help !

All i get from mencoder is this:

mencoder: symbol lookup error: mencoder: undefined symbol: codec_wav_tags

Seems i have this problem: https://bugs.launchpad.net/ubuntu/+source/mplayer/+bug/461966

So, it is unrelated to luciole: there are some conflicting version of ffmpeg libraries around. Perhaps luciole could detect there was a failure exporting?

Yes I agree, luciole should detect this kind of problem.

Is there a workaround ? Could be useful for a FAQ
did you have the libavcodec-extra-52 packaged installed ?

I don't understand very well what happens, but this seems to work: just downgrade ffmpeg to 4:05 (i had the 5:05 version trough the http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu PPA, now i disabled it).
I still have the libavcodec-extra-52 installed (v. 4:05, needed by ffmpeg), but removed libavcodec52 (which conflict with ffmpeg).
