Thank you, Steve, I’ve synced my code base to your commit#. I tried to
configure the code as much like yours as possible. But mine is a Linux box on
HP laptop. For me, the result remains the same �C ffprobe_g was unable to
detect the stream type.

As a result of a typo in the source code, this option was completely
non-functional. In order to fix it, without breaking the current default
(and, upon reconsideration, probably preferred) behavior, explicitly
change this default to 0.

This previous expression multiplied a constant (outlink->h) that was
guaranteed to be 0 at this point, thus making it always a no-op.
Fix the calculation, and also properly reset the SAR to 1:1 as is now
necessary (the failure to do so previously hid this bug's existence).

Adding direct film grain mode for av1 decoder, which
outputs alongside film grain.
AV_HWACCEL_FLAG_DIRECT_FILM_GRAIN is the new flag
introduced to enable this path.

By using AMD av1 decoder via VAAPI, when used with film

Unlike the pipe protocol, fd protocol has seek support if it

Sometimes it's the only way to access files via file descriptor, e.g.,

Hello everyone :)
I was wondering about the behavior of FFmpeg's hashing muxer for audio
streams:
For example:
With a 32bit float (f32le) source, FFmpeg seems to be able to generate a
hash for the f32le source - but only if I explicitly know (and then
tell) FFmpeg to do so.
By default, I ge

Please ignore fail info form loongarch64 patchwork temporarily.
I have stoped the service from Nov 16th, but there are still result post to
patchwork.
Have mailed to Andriy to help analyze this problem together.

Fixes the crash in ticket #10050.
Also ensure that we don't overflow before ff_get_encode_buffer().

AVCodecContext.frame_number is actually only incremented
in case encoding was successfull; if e.g. the ff_alloc_packet()
below fails, it won't be incremented and therefore it is possible
for the previous_frame buffer to be allocated for multiple
first frames, leaking every one except the last.
