[FFmpeg-devel] [PATCH 05/10] avformat/segment: Fix leak of string on error

[Andreas Rheinhardt]

A string containing the segment's filename that the segment muxer
allocates got only freed in its write_trailer function. This implies
that it leaks if write_trailer is never called, e.g. if initializing
the child muxer fails. This commit fixes this by freeing the string
in the deinit function instead.
