ext/ffmpeg/gstffmpegcodecmap.c: Make type explicit.
Original commit message from CVS: * ext/ffmpeg/gstffmpegcodecmap.c: Make type explicit. * ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_release_buffer), (gst_ffmpegdec_frame), (gst_ffmpegdec_chain), (gst_ffmpegdec_change_state): When we provide a buffer and get a valid return value (data was read), but no output (have-data==0), then we need to reuse this same output buffer, because it may be used for caching output data. Fixes #307353. * ext/ffmpeg/gstffmpegdemux.c: (gst_ffmpegdemux_loop): Timestamp fix.
