Hi,

I'm wondering if there are any more comments for this patch? I would
be happy to clarify anything that's unclear or improve the code if
needed.

I know it's pretty late, but it would be really great if this fix
could land before v6.2 is released, so I'd appreciate your help and
review.

Thank you,
Michał

I have reviewed the patch, and the drain sequence handling looks good to me.
Could you share some details on the test client which you are using to catch this issue ?
Hi Vikash,

Thank you for looking at the code!

I've been testing it using the Chromium implementation of the V4L2
codec [1]. Meanwhile, we were running a test suite which changes the
encryption method in the middle of the video decoding. This triggers
the flush behavior and the Chromium sends the stop/start cmd to the
V4L2 kernel component, and the test expects the video to continue the
playback normally. Unfortunately, it was causing a stall of the video
at the same time.

Thank you,
Michał
Thanks,
Vikash
