Romain Vimont	28bce48d47	Relax v4l2_sink lock constraints To fix a data race, commit `5caeab5f6d` called video_buffer_push() and video_buffer_consume() under the v4l2_sink lock. Instead, use the previous_skipped indication (initialized with video buffer locked) to lock only for protecting the has_frame flag. This enables the possibility for the video_buffer to notify new frames via callbacks without lock inversion issues.	3 years ago

Romain Vimont	5caeab5f6d	Fix v4l2 data race The v4l2_sink implementation directly read the internal video_buffer field "pending_frame_consumed", which is protected by the internal video_buffer mutex. But this mutex was not locked, so reads were racy. Lock using the v4l2_sink mutex in addition, and use a separate field to avoid depending on the video_buffer internal data.	3 years ago

Romain Vimont	cd2894570d	Allocate AVPacket for v4l2_sink From FFmpeg/doc/APIchanges: 2021-03-17 - f7db77bd87 - lavc 58.133.100 - codec.h Deprecated av_init_packet(). Once removed, sizeof(AVPacket) will no longer be a part of the public ABI. Refs #2302 <https://github.com/Genymobile/scrcpy/issues/2302>	3 years ago
Romain Vimont	af228706f1	Fix compatibility with old FFmpeg V4L2 sink used a "url" field format AVFormatContext which has been introduced in lavf 58.7.100. Fixes #2382 <https://github.com/Genymobile/scrcpy/issues/2382> Refs <`ea3672b7d6`> Refs <`fa8308d3d4`>	3 years ago

Marco Martinelli	d39161f753	Add support for v4l2loopback It allows to send the video stream to /dev/videoN, so that it can be captured (like a webcam) by any v4l2-capable tool.
