2019-07-30lavd/v4l2: produce a 0 byte packet when a dequeued buffer's size is unexpectedStephan Hilb
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.

2019-05-05avdevice/decklink: fix checking video mode in SDK version 11Marton Balint

2019-04-06lavd/x11grab: fix vertical repositioningOctavio Alvarez
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.

2018-10-23avdevice/sdl2: add option to set window positionDave Rice
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 Signed-off-by: Marton Balint <cus@passwd.hu>

Hook in libklvanc and use it for output of EIA-708 captions over SDI.

2018-05-10lavd/v4l2: Add ARGB and XRGB packed pixel formatsAnton Leontiev
Formats ARGB32, XRGB32, ABGR32, and XBGR32 were added to V4L2 instead of ill-defined deprecated RGB32/BGR32 pixel formats. When pixel format is not specified explicitly FFmpeg tries formats in order in which they are stored in the table. Therefore formats are sorted as follows: BGR is preferred over RGB and XBGR is preferred over ARGB, because it could give better performance by ignoring alpha component.
