[FFmpeg-devel] [PATCH] libavfilter/af_mcompand: Check for failure to allocate memory

[Chris Miceli]

ticket 8931 mentions some missing null pointer checks and so this is one
diff of a few which are for these fixes. There are previous code pieces
which return ENOMEM, so this should work as intended.
