[Description Christian Pontesegger 2011-02-08 21:11:03 UTC]

transcoding from divx, xvid to mpeg2 does not work on my system correctly.I was trying to use the dvd profile but following command

transcode -i input.avi -o output.vob --export_prof dvd-pal 

results in

I tried this for different versions of ffmpeg, but with the same result:
media-video/ffmpeg-0.5_p20373
media-video/ffmpeg-0.6_p25767 

I tried revdep-rebuild, lafilefixer and re-emerging packages mentioned above.



Reproducible: Always

Steps to Reproduce:
1. install transcode (see useflags in description above)
2. run transcode -i input.avi -o output.vob --export_prof dvd-pal 


Actual Results:  
aborts with error message

[Comment 1 Rafał Mużyło 2011-02-08 23:01:36 UTC]

OK, import/Makefile.am needs a simple patch -
adding LIBAVCODEC_LIBS to import_ffmpeg_la_LIBADD.
For completeness, similar correction to import_ffmpeg_la_CPPFLAGS.

[Comment 2 Frédéric COIFFIER 2011-06-05 09:31:08 UTC]

Is there a path somewhere ?

I reproduce the problem with :
[IP-] [  ] media-video/transcode-1.1.5-r2:0
[IP-] [  ] media-video/ffmpeg-0.7_rc1:0

To use transcode-1.1.5-libavcodec.patch

[Comment 5 Amir Aupov 2011-08-27 17:34:06 UTC]

I've had similar issue, but with symbol "avcodec_decode_video", which is deprecated (maybe  since 0.7.2) (http://cekirdek.pardus.org.tr/~ismail/ffmpeg-docs/avcodec_8h.html#812b0ba18511f3c8787294bce7b06372). The solution is to change the code a bit and use "avcodec_decode_video2", as it was done in transcode-1.1.5-ffmpeg.patch. The patch is attached.

I believe this is a duplicate of 334293 and fixed in transcode-1.1.7.
