If the same instance of the plugin is asked to be initialised more that once,
instances after the first one do not register the elements properly and the
elements become not usable.
For example, if you call gst_update_registry (), is not possible to create
elements after the call since the plugin is asked to be initialised again and
does not register the elements.
Fixes#584291
If the set of caps for either audio or video is completely empty, skip
adding that pad template to the class. Some muxers only support audio-only
or video-only and otherwise end up with EMPTY caps in the pad template.
AVOutputFormat does *NOT* contain the full list of codecs a muxer can handle,
but does contain the recommended audio and video codecs. Therefore we use that
information to expose more muxers, until AVOutputFormat contains a list of
*ALL* compatible codecs.

Fix tag merging. Use tagsetter and not internal copies. Depend on
CVS core and use new API to flush.
Original commit message from CVS:

Copy the codec aspect ratio to the stream, ffmpeg expects them to be the
same. Fixes#560305.

Require libavutil for swscale too when building with an external
ffmpeg and fix includes for external ffmpeg.

Don't use GINT_TO_POINTER and GPOINTER_TO_INT with GTypes, this
can break horribly if sizeof(GType) happens to be bigger than
sizeof(int), because GPOINTER_TO_INT might then chop off some bits
of our GType (the reason this seems to works nevertheless is the
put-current-type-also-as-value-0-into-the-hash-table-as-fallback
hack used in the current code).
In any case, instead of just fixing this, let's not use a hash table
with GTypes here at all. g_type_{set|get}_qdata() seems to do the
job just as well.
Original commit message from CVS:
* ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_register):
ffmux_flv only accepts mpeg audio with a sample rate of 44100, 22050
or 11025. Fix up the caps in the sink pad template accordingly, so
that encoding piplines at least have a chance to automatically
negotiate to one of the allowed rates.
Original commit message from CVS:
* ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_request_new_pad),
(gst_ffmpegmux_setcaps), (gst_ffmpegmux_collected):
Only set the mux->opened flag after we've successfully written the
header. This way we don't crash in mysterious ways if we can't write
the header for some reason (e.g. due to having accepted caps the
format doesn't really allow), then return a GST_FLOW_ERROR, and
then still receive another buffer afterwards despite having previously
returned FLOW_ERROR (#403168).
Also some minor logging improvements.
Original commit message from CVS:
* ext/ffmpeg/gstffmpegcodecmap.c:
(gst_ffmpeg_formatid_get_codecids), (gst_ffmpeg_caps_to_codecid):
Add mmf to _get_codecids, so we can use the mmf muxer.
Use "audio/x-adpcm" rather than the dubious looking "x-adpcm" as our
caps type for the adpcm variants.
* ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_base_init):
Allow muxers that allow either only audio or only video, needed for
mmf (audio only).
Original commit message from CVS:
* ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_collected):
The ->frame_size for RAW audio is 1.
Should fix behaviour of some muxers.
Original commit message from CVS:
* ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_change_state):
We need to stop the collectpads in PAUSED->READY BEFORE chaining up to
the parent class change_state. Else we end up in a locking behaviour
with the sink pads stream locks.
Original commit message from CVS:
* ext/ffmpeg/gstffmpegmux.c: (gst_ffmpegmux_request_new_pad),
(gst_ffmpegmux_sink_event), (gst_ffmpegmux_collected):
Port tag-writing support in the muxers.
