[FFmpeg-devel] [PATCH] libavcodec/zmbv.c: Don't modify const buffer

[Patrik Kullman]

Trying to solve this issue somewhere else than BSFs until that API is
sorted out.

Copy the const input buffer into the Zlib struct instead of using the
same address.

Prevents warning:
libavcodec/zmbv.c: In function ?decode_frame?:
libavcodec/zmbv.c:494: warning: assignment discards qualifiers from
pointer target type

After inflate() is complated, free next_in.
