[FFmpeg-devel] [PATCH 1/2] avformat/jacosubenc: Fix writing extradata

[Andreas Rheinhardt]

The terminating '\0' is no longer included in the size of
the extradata output by the demuxer since commit
36e61e24e7ac737b38c4382d439329352d9e0c29.
E.g. if one remuxes the JACOsub sample JACOsub_capability_tester.jss
from the FATE suite, one receives a file not recognized as JACOsub
before this patch.
