c810a9502c avfoundation: Fix building on iOS 
Apparently the changes from 3c9185bf3a
aren't enough; even with that in place, I got errors like this
when trying to build for iOS:

7b2ce27e56 avdevice/v4l2: Remove av_assert0 when format not supported 
Before this commit an av_assert0 would fail if a v4l2 device did not
support a target format.
For example,
./ffmpeg -f v4l2 -codec:v h264 -i /dev/video0 -f mpegts -
would signal an abort if /dev/video0 did not support h264.

The new behaviour is to return an AVERROR(EINVAL) error code. An
av_assert0 has been added to verify this return.

Fixes #6629

b761ae072a lavd/v4l2: produce a 0 byte packet when a dequeued buffer's size is unexpected 
Behave like we do for V4L2_BUF_FLAG_ERROR, implemented in commit 28f20d2ff4 .

For some devices (probably also related to the V4L driver implementation)
it happens that when invoking the ioctl DQBUF, the returned buffer is not
of the expected size. Here are two examples for such occurrences:

    [video4linux2,v4l2 @ 0x258b440] Dequeued v4l2 buffer contains 609596 bytes, but 614400 were expected. Flags: 0x00000001.
    /dev/video1: Invalid data found when processing input

    [video4linux2,v4l2 @ 0x225f440] Dequeued v4l2 buffer contains 609508 bytes, but 614400 were expected. Flags: 0x00000001.
    /dev/video1: Invalid data found when processing input

For the ffmpeg CLI tool this means it will stop capturing and exit.

The described behaviour was observed at least with one OmniVision USB
web cam and with some stk1160 devices.

If you search the web for the error message, you will find quite a few
instances of this problem. Some of them experienced on other devices.

Probably fixes ticket #4795
