[FFmpeg-devel] [PATCH v5 00/13] dshow enhancements

[Diederick Niehorster]

This series solves some outstanding bugs in the dshow device, implements
get_device_list so that `ffmpeg -sources dshow` works and adds logic to
select a video format with extended color information (color range,
space, etc) if exposed by the device.

v5 adresses a comment received offlist for patch 5/13 (now emits log
message when a sample timestamp is missing.

This is a new version of part of the patch series in
https://ffmpeg.org/pipermail/ffmpeg-devel/2021-July/282073.html,
addressing review comments i got there. They have been previously OK'ed
offlist by the dshow maintainer Roger Pack. Specifically, these patches
are the enhancements that should be uncontroversial as they do not touch
the avformat API. I hope they can be swiftly pushed by someone, then
i'll re-send the other more controversial patches on top of these.
