7d3f221d87 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.

19359e2b25 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.

1d534ac209 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

Strip off any leftover bytes and assume everything before that is valid.

85969fdaa7 level: Fix integer overflow when filling LevelMeta
The level in GstAudioLevelMeta is represented as a signed 8bit value from 0 to
127 (with 127 meaning silence). When converting from double, make sure to clip
the value, this also prevent integer overflow in the conversion. This fixes an
issue where a lower then -127db is reported and random level with near silent
streams (due to integer overflow).

fbad7b593d validate-scenario: Fix busy waiting, missing lock
execute_next_action_full() logs that it removes the source when an
action returns ASYNC, but the code for that was incomplete, as it was
setting source_id to zero but not actually removing the source.

This lead to execute_next_action_full() being run continuously, only
alliviated by the default 10ms interval in the GSource from
`scenario->priv->action_execution_interval`.

This patch fixes that. As a drive-by fix it also adds locking to one
remaining unlocked usage of `priv->execute_actions_source_id`.

There were a couple strings containing \(. That is not a valid escape

such either the backslash should be doubled or a raw string must be
used. This patch uses the latter for readability.

Python 3.13 will print a warning when a invalid escape sequence in a
string is found.

984956a6fe vkencoder-private: fix parameters overrides
First remove validations since they will fail if there isn't a write operation.
It's valid to pass data without write operations.

Finally, it should check for hasOverride in feedback info. Nonetheless, there's
a NVIDIA bug returning always FALSE for hasOverride, that's why we currently
force it to TRUE.

835e232e8c rtspsrc: Use a flow combiner at the source pads instead of custom logic
Most importantly, this ensures that UDP streams still continue to run even if
they are not linked for a while. With decodebin3 the pads will all be unlinked
unless selected, and selecting a stream at a later time would otherwise switch
to a stream with a stopped udpsrc.

Apart from that this also ensures that actual errors from handling RTP packets
between udpsrc and the source pads are not silently ignored but considered
errors like they would be for TCP/interleaved.
