/usr/bin/transcode: symbol lookup error: /usr/lib/transcode/export_ffmpeg.so: undefined symbol: avcodec_encode_video

[Luca Olivetti]

When I try to rip a dvd with k3b (selecting mpeg4 as the output format(, this is the failure message I get from transcode

/usr/bin/transcode: symbol lookup error: /usr/lib/transcode/export_ffmpeg.so: undefined symbol: avcodec_encode_video

ldd shows that /usr/lib/transcode/export_ffmpeg.so uses /usr/lib/x86_64-linux-gnu/libavcodec.so.56 which has an avcodec_encode_video2 but no avcodec_encode_video function:

transcode needs to be ported to use the new avcodec_encode_video2 API, the
old API has been deprecated long ago and is no longer available now.
