Hey Patrick,
When rendering to .webm, kdenlive passes
acodec=vorbis
to melt.
Here's an example
$ /usr/bin/melt /tmp/saved.mlt in=0 out=63 -profile atsc_1080p_25 -consumer
avformat:/home/kingsley/tmp/test.webm f=webm vcodec=libvpx acodec=vorbis crf=23
vb=0 quality=good aq=6 max-intra-rate=1000 cpu-used=4 threads=1 real_time=-1
But, it crashes with a seg fault.
ffmpeg's audio codec documentation says to use
libvorbis[1].
libvorbis works for me.
$ /usr/bin/melt /tmp/saved.mlt in=0 out=63 -profile atsc_1080p_25 -consumer
avformat:/home/kingsley/tmp/test.webm f=webm vcodec=libvpx acodec=libvorbis
crf=23 vb=0 quality=good aq=6 max-intra-rate=1000 cpu-used=4 threads=1
real_time=-1
rendered OK.
Could kdenlive be passing a bad option to melt
(and ffmpeg/libav*)?
Thanks,
Kingsley
