Bug#1013301: ffmpeg: WebVTT subtitle parsing is broken
Package: ffmpeg
Version: 7:5.0.1-1+b2
Severity: normal
Tags: upstream patch
The WebVTT decoder in ffmpeg breaks when there are common chunks like
STYLE and REGION in the file. An upstream bug is here:
https://trac.ffmpeg.org/ticket/8684
The ffmpeg patchwork server contains several patches fixing this problem
(see https://patchwork.ffmpeg.org/project/ffmpeg/list/?q=webvttdec for a
list). These range from outright ignoring the chunks
https://patchwork.ffmpeg.org/project/ffmpeg/patch/20210112164937.7219-1-roderich.schupp@gmail.com/
to actually parsing and using them
https://patchwork.ffmpeg.org/project/ffmpeg/patch/CA+_k4RJ1CNriPbhxxzLf1O6V1VuP2OXch3E8LqOsMNSRUyEnTw@mail.gmail.com/
Could you include one of these in the Debian build, since upstream does
not seem to be interested in this?
