[FFmpeg-devel] [PATCH] qdm2 decoder: return actually used data size

[Reimar Döffinger]

Hello,
currently the qdm2 decoder always returns the input buffer size.
IMO it should instead return how much of the data it actually used.
This allows e.g. playing a qdm2 stream even if somehow some packets
become mangled together (happens e.g. with MPlayer's mov demuxer).
Any objections?
