Source: blender
Version: 6.3.1
Severity: serious
Tags: patch upstream
Justification: Fails to build from source
In addition to #654428, blender also fails to build from source because
of API changes in libav 0.9~beta2. Attached is a patch which fix all (3)
the issues I found until #654428 build failure.
Note the change related to avformat_alloc_output_context2 in
ffmpeg_compat.h header. Blender is likely to need the same kind of
change when a future version of libav will be uploaded to Debian.

Description: Adapt to libavutil API changes

avformat_alloc_output_context2() should be in the libavformat 53.2.0 but
it isn't in Debian, re-define it.
