Andriy Gelman 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

Stephan Hilb 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

Octavio Alvarez f4f40cbb57 lavd/x11grab: fix vertical repositioning
There is a calculation error in xcbgrab_reposition() that breaks
vertical repositioning on follow_mouse. It made the bottom
reposition occur when moving the mouse lower than N pixels after
the capture bottom edge, instead of before.

This commit fixes the calculation to match the documentation.

follow_mouse: centered or number of pixels. The documentation says:

When it is specified with "centered", the grabbing region follows
the mouse pointer and keeps the pointer at the center of region;
otherwise, the region follows only when the mouse pointer reaches
within PIXELS (greater than zero) to the edge of region.

Dave Rice 110b4a4918 avdevice/sdl2: add option to set window position
Allows arrangement of multiple windows such as:
ffmpeg -re -f lavfi -i mandelbrot -f sdl -window_x 1 -window_y 1 mandelbrot -vf waveform,format=yuv420p -f sdl -window_x 641 -window_y 1 waveform -vf vectorscope,format=yuv420p -f sdl -window_x 1 -window_y 481 vectorscop

Some changes by Marton Balint:
- allow negative position (partially or fully out-of-screen positions seem to
  be sanitized automatically by SDL (or my WM?), so no special handling is
  needed)
- only show window after the position is set
- do not use resizable and borderless flags at the same time, that caused
  issues in ffplay
- add docs
