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.
