Original commit message from CVS: * ext/ffmpeg/gstffmpeg.c: (plugin_init): Enable muxers (only mp4 muxer for now). * ext/ffmpeg/gstffmpegcodecmap.c: (gst_ffmpeg_formatid_get_codecids), (gst_ffmpeg_caps_to_codecid): * ext/ffmpeg/gstffmpegcodecmap.h: Fix a bunch of typos in codec-id lookup (false/true return value mixup), add a codec-id list retrieval function (because ffmpeg does not provide one). With that, we can make valid pad templates. * ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_init), (gst_ffmpegmux_connect), (gst_ffmpegmux_loop), (gst_ffmpegmux_change_state), (gst_ffmpegmux_get_id_caps), (gst_ffmpegmux_register): Fix for whatever changed since I last tried this. Works for MP4 muxing. * ext/ffmpeg/gstffmpegprotocol.c: (gst_ffmpegdata_open), (gst_ffmpegdata_peek), (gst_ffmpegdata_write), (gst_ffmpegdata_seek), (gst_ffmpegdata_close): Update obviously-untested write code...
