Peter Rekdal Sunde	042c486b68	Obtain fourcc when `AVStream` is network stream The `codec_tag` is only available when opening a file from disk. If `AVStream` is a network stream then `fourcc` must be obtained using `codec_id`. I have tested the following scenarios: 1) Open a `.mp4` file and verify that `codec_tag` is returned (old behavior) 2) Open a `rtsp` stream and verify that `codec_fourcc` is returned (Tested with a MJPEG, H264 and H265 stream)	6 years ago

Todor Tomov	9988e1b6ee	cap_v4l: Fix private control enumeration end condition Currently the private control enumeration will be stopped when QUERYCTRL returns -EINVAL only. It is possible however that other errors occur. One particular case is when the v4l2 device doesn't support any controls and doesn't implement the QUERYCTRL ioctl. In that case the v4l2 framework returns -ENOTTY. In that case the current control enumeration will go in an endless loop. To fix this change the control enumeration stop condition. If any errors occur, end the control enumeration. Signed-off-by: Todor Tomov <todor.tomov@linaro.org>	6 years ago

Kaartic Sivaraam	a527e8cc73	cap-v4l: remove unwanted loop in V4L2 mainloop The while loop would run only once making it useless and leading to confusion. So, remove the unwanted while loop and just keep an infinite for loop.	6 years ago

Alexander Alekhin	9629af1aa9	videoio: MSMF async reader for camera stream Synchronized reading from camera with heavy frame processing provides bad effects (huge frame latency, processing frames from the past). Generally, there is no way to process each frame and some frames will be dropped. Allow preventive frame dropping to reduce lag of processed frames. This mode is applied to cameras only (opened by 'index').	7 years ago
