Subject: [PATCH] jitterbuffer: Allow rtp caps without clock-rate
The jitterbuffer shouldn't force clock-rate on its sink pad, this will cause a negotiation issue since rtpssrcdemux doesn't have the clock-rate and doesn't add it to the caps. The documentation states that the clock-rate can either be specified through the caps or through the request-pt-map signal, so we must remove clock-rate from the pad templates and we must accept the GST_EVENT_CAPS if the caps don't have the clock-rate.

Subject: [PATCH 09/28] wavparse: Fix clipping of size to the file size
The size does not include the 8 bytes tag and length, so an additional 8 bytes
must be removed here. 8 bytes are always available at this point because
otherwise the parsing of the tag and length right above would've failed.
Thanks to Antonio Morales for finding and reporting the issue.

Subject: [PATCH 20/28] qtdemux: Make sure only an even number of bytes is
processed when handling CEA608 data
An odd number of bytes would lead to out of bound reads and writes, and doesn't
make any sense as CEA608 comes in byte pairs.
Strip off any leftover bytes and assume everything before that is valid.
Thanks to Antonio Morales for finding and reporting the issue.

Subject: [PATCH 24/28] qtdemux: Make sure there are enough offsets to read
when parsing samples
While this specific case is also caught when initializing co_chunk, the error
is ignored in various places and calling into the function would lead to out of
bounds reads if the error message doesn't cause the pipeline to be shut down
fast enough.
To avoid this, no matter what, make sure enough offsets are available when
parsing them. While this is potentially slower, the same is already done in the
non-chunks_are_samples case.
Thanks to Antonio Morales for finding and reporting the issue.

Subject: [PATCH 25/28] qtdemux: Actually handle errors returns from various
functions instead of ignoring them
Ignoring them might cause the element to continue as if all is fine despite the
internal state being inconsistent. This can lead to all kinds of follow-up
issues, including memory safety issues.
