811f2f91da avformat/mov: discard data streams with all zero sample_delta
Streams with all zero sample_delta in 'stts' have all zero dts.
They have higher chance be chose by mov_find_next_sample(), which
leads to seek again and again.

For example, GoPro created a 'GoPro SOS' stream:
  Stream #0:4[0x5](eng): Data: none (fdsc / 0x63736466), 13 kb/s (default)
    Metadata:
      creation_time   : 2022-06-21T08:49:19.000000Z
      handler_name    : GoPro SOS

With 'ffprobe -show_frames http://example.com/gopro.mp4', ffprobe
blocks until all samples in 'GoPro SOS' stream are consumed first.

6ca43a9675 avdevice/lavfi: output wrapped AVFrames
This avoids an extra copy of potentially quite big video frames.
Instead of copying the entire frames data into a rawvideo packet it
packs the frame into a wrapped avframe packet and passes it through
as-is.
Unfortunately, wrapped avframes are set up to be video frames, so the
audio frames continue to be copied.

Additionally, this enabled passing through video frames that previously
were impossible to process, like hardware frames or other special
formats that couldn't be packed into a rawvideo packet.

64f04df379 avdevice/avdevice: fix return value of avdevice_list_devices()
According to API docs avdevice_list_devices(), avdevice_list_input_sources()
and avdevice_list_input_sinks() should return the number of autodetected
devices on success. This is redundant with AVDeviceInfoList->nb_devices so it
was not noticed earlier that none of the underlying device list functions work
like that.

Let's fix it in generic code to make it in line with the API docs.

Fixes ticket #9820.

940169b8aa avcodec/libjxlenc: avoid hard failure with unspecified primaries
This patch prevents the libjxl encoder wrapper from failing to
encode images when the input video has untagged primaries. It will
instead assume BT.709/sRGB primaries and print a warning.

4136405c86 aarch64: me_cmp: Don't do uaddlv once per iteration
The max height is currently documented as 16; the max difference per
pixel is 255, and a .8h element can easily contain 16*255, thus keep
accumulating in two .8h vectors, and just do the final accumulationat the
end. This should work for heights up to 256.

This requires a minor register renumbering in ff_pix_abs16_xy2_neon.

Before:       Cortex A53    A72    A73   Graviton 3
pix_abs_0_0_neon:   97.7   47.0   37.5   22.7

68a03f6424 aarch64: me_cmp: Switch from uabd to uabal in ff_pix_abs16_xy2_neon
Using absolute-difference-accumulate does use twice the amount of
absolute-difference instructions, but avoids the need for the
uaddl and add instructions, reducing the total number of instructions
by 3.

These can be interleaved in the rest of the calculation, to avoid
tight dependencies at the end. Unfortunately, this is marginally
slower on Cortex A53, but faster on A72 and A73.

882aac99d2 ffmpeg: add option -isync
This is a per-file input option that adjusts an input's timestamps
with reference to another input, so that emitted packet timestamps
account for the difference between the start times of the two inputs.

Typical use case is to sync two or more live inputs such as from capture
devices. Both the target and reference input source timestamps should be
based on the same clock source.

If either input lacks starting timestamps, then no sync adjustment is made.
