| | | | | | | | | | | | Apparently the changes from 3c9185bf3a83395d12a987f626dbdb985eac4320 aren't enough; even with that in place, I got errors like this when trying to build for iOS: src/libavdevice/avfoundation.m:135:5: error: 'AVCaptureDeviceTransportControlsPlaybackMode' is unavailable: not available on iOS AVCaptureDeviceTransportControlsPlaybackMode observed_mode; ^

* avdevice/v4l2: Remove av_assert0 when format not supportedAndriy Gelman2019-11-061-1/+2
| | | | | | | | | | | | | | | | | 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.

* lavd/v4l2: produce a 0 byte packet when a dequeued buffer's size is unexpectedStephan Hilb2019-07-301-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lavd/x11grab: fix vertical repositioningOctavio Alvarez2019-04-061-1/+1
| | | | | | | | | | | | | | | | 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.
