Hi,
I'm wondering if it is possible to use two passes to generate segments
because the command I run failed.
The following command using passes failed:
ffmpeg -y -i ./maradona.wmv -vcodec libx264 -vprofile main -preset slow
-b:v 300k -vf scale=480:360 -vbsf h264_mp4toannexb -flags -global_header
-map 0 -f segment -segment_time 10 -segment_list index.m3u8 -threads 1
-pass 1 -passlogfile /tmp/ff_maradona.ts -an /dev/null
...
Could not write header for output file #0 (incorrect codec parameters
?): Muxer not found
whilst the same command that is not using the two passes was
successful:
ffmpeg -y -i ./maradona.wmv -vcodec libx264 -vprofile main -preset slow
-b:v 300k -vf scale=480:360 -vbsf h264_mp4toannexb -flags -global_header
-map 0 -f segment -segment_time 10 -segment_list index.m3u8 -threads 1
-acodec libvo_aacenc -b:a 96k /tmp/ff_maradona_191_%04d.ts
So the question is: can be used two steps to generate segments? And
if yes, what I'm wronging
in the above command?
Thanks
