From: Romain Beauxis <[email protected]>
This is a series of patches that fix and enhances libavdevice & have been
submitted multiple times in the past 6 months. In the series, the most
straightforward patches have been placed first in the list.
While I have a lot of appreciation for all the solid work done in this project,
seeing the difficulty in getting them included makes one wonder what is the
status of libavdevice and if it is still actively maintained.
Typically, in the first patch, we fix the name/machine readable ID of dshow
devices. If the API has any significant use or maintenance, this should have
been caught and fixed much sooner.
Next, the patches fixing the avfoundation device audio format and concurrency
models are absolutely required to get any use of this operator as audio input
and, quite likely, as video input as well.
This is a lot of changes to make the library usable for a cross-platform
project and, with the lack of traction with the changes, this makes the
developer wonder if the library is ready for production use and if it wouldn't
be easier to implement hardware handling separately and plug into FFmpeg after
retreiving media data.
There are more that I have noticed with the API, in particular the fact that
audio/video devices are labelled as video. I would love to submit changes to
enhance that aspect but, not with all these patches already pending..
Thanks for y'all consideration.
