The extradata allocated in mov_write_single_packet() for AV1 was missing
the required AV_INPUT_BUFFER_PADDING_SIZE padding bytes. This could lead
to out-of-bounds reads when the extradata is parsed by bitstream readers.
Replace av_memdup() with av_malloc() + memset() + memcpy() to ensure
proper padding is present and zeroed.
Reproduced with:
./ffmpeg -y -f lavfi -i "testsrc=duration=1:size=320x240:rate=30" -c:v libaom-av1 -cpu-used 8 -crf 50 test-av1.mp4

Extract the Sample Aspect Ratio (SAR) from render_width_minus_1 and
render_height_minus_1 in the sequence header.
The AV1 specification defines the render dimensions, which can be used
in conjunction with the coded dimensions to determine the pixel aspect
ratio. This ensures consistent aspect ratio handling for AV1 streams
encapsulated in containers like MP4 or MKV, as observed in the updated
FATE tests where SAR changes from 0/1 to 1/1.

Its rarely respected by implementations, its fairly new (1 year old),
and it has a scuffed define (neither glslc nor glslang enable the
"GL_EXT_nontemporal_keyword" define if its enabled, unlike all other extensions).
We use INT32_MIN/MAX so as to ensure we dont have to deal with 64bit width or height
on a int is int64 system. int64 width would overflow in a system where we assume the product of 2
values fit in int64

Also, fix the logic in probe_glslc() so it doesn't return false when debug is disabled.

This commit implements ROI (Region of Interest) encoding support for D3D12VA hardware encoders, enabling spatially-adaptive quality control for H.264, HEVC, and AV1 encoders.
Query for `D3D12_VIDEO_ENCODER_RATE_CONTROL_FLAG_ENABLE_DELTA_QP` support during initialization to check whether the hardware support delta QP. If delta QP is supported, then process `AV_FRAME_DATA_REGIONS_OF_INTEREST` side data and generate delta QP maps for each frame.
Sample command line:
ffmpeg.exe -hwaccel d3d12va -hwaccel_output_format d3d12 -i input.mp4 -vf addroi=x=480:y=270:w=960:h=540:qoffset=-1/5 -c:v hevc_d3d12va output.mp4
Update execute_model_th to support asynchronous execution by pushing tasks to the pending queue and notifying the worker thread.

While the inclusion of the bsf is forced by a configure check, it's better to not
just have the code here assume filter will never be NULL.

Previous code truncated chapter numbers more than 999 and and time offsets more
than 99 hours.
The Vorbis comment format only allows 1000 chapters, so cap the number of
written chapters there.
This also fixes the GCC warnings for truncated strings.

This way we can ensure a frame reference will always exists for as long as the
