Summary of the bug:
I have already-generated .webm audio and video files (1 audio, 3 video
resolutions for each video I want to stream). The video has been generated
not by ffmpeg, but HandbrakeCLI 1.7.0, with V9 encoding. The audio (which
has never caused an error) is generated by ffmpeg using libvorbis.
Most of the time ffmpeg creates a manifest without any problem.
Sporadically, however, "Error parsing Cues" comes up, maybe 1 out of 5
times, and I can't create a manifest. Since this is happening during an
automated process to process many videos for streaming, the audio and
video sources are being created exactly the same way whether ffmpeg
succeeds or fails in generating a manifest, making this all the more
confusing.
The video files ffmpeg chokes on play perfectly well using VLC, and
mediainfo doesn't show any problems with the files.
How to reproduce:
Here is the command I've been using:
{{{
ffmpeg -v 9 -loglevel 99 -f webm_dash_manifest -i '.\Sample
Video.v480.webm' -f webm_dash_manifest -i '.\Sample Video.v720.webm' -f
webm_dash_manifest -i '.\Sample Video.v1080.webm' -f webm_dash_manifest -i
'.\Sample Video.audio.webm' -c copy -map 0 -map 1 -map 2 -map 3 -f
webm_dash_manifest -adaptation_sets "id=0,streams=0,1,2 id=1,streams=3"
'.\Sample Video.mpd'
}}}
Here is the output generated:
