b300552dfb avformat/mov: enable identifying TTML subtitle streams as such
The contents are full TTML XML documents. TTML writing tests'
results are updated as the streams are now properly identified
as TTML ones.

7de3fcb059 examples: fix build of mux and resample_audio
The commits eac4324bfb and
cd8211527e renamed the examples, but the
targets were not updated. Hence, the builds are missing -lm.

27804200ef vulkan_hevc: use diagonal scan order for scaling lists
The hevc parser parses the diagonal scan order in bitstream into raster
scan order. However, the Vulkan spec wants it as specified in H265 spec,
which is diagonal scan order.

Tested on RADV.

v2: fix copy-paste typo with PPS.

4fa1d3e791 avcodec/v4l2_context: suppress POLLERR and fix crash when buffers are uninitialized
A POLLERR occurs when libavcodec attempts to dequeue output buffers
before enqueuing capture buffers. This could happen to an application
deciding to send the first coded packet. Suppress these POLLERRs when
the buffers are uninitialized and avoid crashing because of enumerating
uninitialized buffers.

See https://trac.ffmpeg.org/ticket/9957 for the original bug report.

43e63ff20a avcodec: move content light level SEI handling to h2645_sei
This allows this common H.274 SEI to be parsed from both H.264
as well as HEVC, as well as probably from VVC in the future.

Generally attempts to keep the original code as similar as possible.

FATE test refererence changes only change the order of side data
export within a single frame. Nothing else seems to have changed.

where its read, which desynced on HEVC streams.

For clarity, move the size offset directly to the parsing, similar to
how its done for all other header fields.
