[FFmpeg-devel] [PATCH v2] avformat/smoothstreaming: Don't write trailer of subcontext

[Andreas Rheinhardt]

Nothing written in avformat_write_trailer() for the submuxers will be
output anyway because the AVIOContexts used for actual output have been
closed before the call. Writing the trailer of the subcontext has probably
only been done in order to free the memory allocated by the submuxer.
And this job has been taken over by the deinit functions.

Resending because 82bf41f3abce4a13e7c6ad1606eb708f371de87f created a
little merge conflict.
