77429e4096 tsmux: Simplify tsmux_section_write_packet 
- Don't try to make the parameters match `GHFunc`. Use a dedicated
  callback for `g_hash_table_foreach`.
- Don't try to be clever with buffer memories. We're allocating a full
  packet anyway, might as well memcpy and save on a lot of complexity.

c205086f2b tsmux: tsmux_packet_out should always consume its buffer 
Consuming the buffer only when successful is an antipattern and easily
leads to leaks.

4311de2be0 interaudiosink: Ensure adapters don't store buffers with audio meta 
The interaudiosrc might take buffers of different sizes from the audio adapter,
so keeping metas consistency would be an issue. So the sink now strips the audio
metas away and the src adds them back (for non-interleaved layouts only) when
taking buffers from the adapter.

1edd1c38dc mxfdemux: Check number of channels for AES3 audio

integer overflows when copying the data, and lead to out of bound

0fe375dc84 sdpdemux: ensure that only one srcpad is created per stream 
If two senders use the same multicast IP and port then new_session_pad()
may try to add a srcpad to the same stream twice.

stream->srcpad is updated but gst_element_add_pad() fails the second
time. As a result stream->srcpad points to a deleted object and
access in gst_sdp_demux_stream_free() fails with a segfault.

Just ignore the second pad. Nothing useful can be done with it anyway.

7af495072a jpegparse: reset parse state when the SOI is not the first marker 
There may be garbage or some bits before a SOI comes in some problematic
mjpeg streams. For example, some network error may cause the EOI marker
of the previous frame lost, and when the new frame's SOI comes, we still
use the state of the last frame, which will generate errors.

For this kind of frames without EOI, if that frame already has some data
(the SOS segment is detected), we still push it as a frame with CORRUPTED
flag set. But if not, we just discard all the data before the new SOI.

bd91768692 mxfmux: Add all local tags to the primer 
No matter if they're allocated via GSlice or malloc(). The allocator is
completely irrelevant, all local tags need to be in the primer so they
can be handled.

This didn't have any effect in practice because all local tags that
appear in the muxer are allocated via GSlice. Only from the demuxer they
might be allocated via malloc().

f18186b5dc mpegts: Always clear packetizer on DISCONT push mode 
If a discontinuity is detected in push mode, we need to clear the cached section
observations since they might have potentially changed.

This was only done properly when operating with TIME segments (dvb, udp,
adaptive demuxers, ...) but not with BYTE segments (such as with custom app/fd
sources).

We still don't want to flush out the PCR observations, since this might be
needed for seeking in push-based BYTE sources.
