Glad to know my solution worked :D

Should be a matter of moving the relevant chunk to h264_init_ps(), i think.

Maybe instead change the export_stream_params() prototype to have the
callers directly pass HEVCContext *s and HEVSPS *sps, then declare
HEVCParamSets *ps = >ps here. Could also do HEVCSEI *sei = >sei,
so it's consistent.

I don't think these are available at this point. It's a per frame SEI,
and this function is called before slice data is parsed.
Notice how a53_caption is freed as soon as it's exported as frame side
data in set_side_data().

Could we not? The idea is to eventually kill these, so we should at

[FFmpeg-devel] [PATCH V2] lavfi/lut: Add slice threading support
From: Jun Zhao
Used the command for 1080p h264 clip as follow:
a). ffmpeg -i input -vf lutyuv="u=128:v=128" -f null /dev/null
b). ffmpeg -i input -vf lutrgb="g=0:b=0" -f null /dev/null
after enabled the slice threading, the fps change from:
a). 144fps to 258fps (lutyuv)
b). 94fps to 153fps (lutrgb)
in Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz

I almost committed this, but found another issue: the JSON output
contained the "timecode" key multiple times. Apparently in order for the
JSON output to work, we need a separate section for arrays.
I managed to make those changes (see the attached patch), it affected the
XML output slightly as well. Please let me know if this is satisfactory to
you.
Thanks,

Good. The patch that apparently aroused your interest in the
webm_chunk muxer was part of a patchset that was mainly about fixing
ticket #5752, a NULL pointer dereference. Would you mind taking a look
at the other patches? They are here:

I'm not sure what to think about a dummy option like this. It might be
very confusing for users to see a format option, which only accepts a
single value, "same", and effectively does nothing.
Not sure I understand the issue. "same" is the default (terminology
borrowed from the scale_npp filter), and it'll assign the format to
whatever is passed in (eg, format=yuv420p assigns that).
Oh, I misread that code as just always throwing an error if it's != "same".
Unfortunately, that option is omitted for a reason.
If you look at scalecuda_resize:
https://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavfilter/vf_scale_cuda.c;h=b7cdb81081ff4a34e7b641c533fc23a5714fed61;hb=HEAD#l380
It has the assumption built into it that the output frame has the same
format as the input frame. So if you were to set format=nv12 and then
input a yuv420p frame, this will most likely crash or at least severely
misbehave.
I would not be opposed to scale_cuda gaining the ability to also change
frame pix_fmts, we are lacking such a filter at the moment if one
ignores scale_npp.
But in its current state, it can't do that.
Not strictly against it, since I can see the convenience it adds when
building command lines, but I'd like some second opinions on this.
Actually I'm using the API, albeit with some of lavfi conveniences to
parse filter strings. This avoids "wiring in" the output format
manually when crossing the lavfi boundary.
Here's a example that demonstrates the issue via CLI (this may
actually be a bug elsewhere?):
Broken:
ffmpeg -loglevel verbose -hwaccel cuvid -c:v h264_cuvid -i input.ts
-an -lavfi scale_cuda=w=426:h=240,hwdownload,format=yuv420p -c:v
libx264 out.ts
Working:
ffmpeg -loglevel verbose -hwaccel cuvid -c:v h264_cuvid -i input.ts
-an -lavfi scale_cuda=w=426:h=240:format=yuv420p,hwdownload,format=yuv420p
-c:v libx264 out.ts
Is this actually working in a sense where the result looks sensible?
Cause with how the code currently is, scale_cuda with format set to
yuv420p and getting nv12 as input from h264_cuvid will produce a frame
labeled as yuv420p but containing nv12 data.

[FFmpeg-devel] [PATCH] lavfi/vf_scale_cuda: Reset frame size after acquiring from hwframe.
The first frame is scaled correctly, and subsequent frames are over-scaled / cropped since the frame data is reset with the hwframe after each invocation of the scaler. The hwframe-allocated frame has a width/height that is 32-bit aligned. The scaler uses this aligned width / height as its target, leading to "over-scaling" and then cropping of the result. To generate a broken test sample: ffmpeg -hwaccel cuvid -c:v h264_cuvid -i -an \ -lavfi scale_cuda=w=426:h=240 -c:v h264_nvenc --- Tested with NV12 and 420P inputs.

Not sure I understand the issue. "same" is the default (terminology
borrowed from the scale_npp filter), and it'll assign the format to
whatever is passed in (eg, format=yuv420p assigns that).

Actually I'm using the API, albeit with some of lavfi conveniences to
parse filter strings. This avoids "wiring in" the output format
manually when crossing the lavfi boundary.

Since we now have a generic wrapper function, isn't that better for future maintenance? Not that I see. Something that makes it harder to follow the code from the call site to the actual function is not good for maintenance. The point of modularizing the op here is to have a single interface - why stick with a direct external call? At the time it was added, there was no alternative. Don't mind it either way, but this feels like a useless game of ping-pong. Just stick to unlink. If there is no reason to change it, then the preference is to just keep it as-is. We're not using the file protocol to create the file, so no reason to use it to delete it. Will push tonight.

[FFmpeg-devel] [PATCH 7/7] libavfilter/vf_overlay.c: add the yuv420p10 10bit support
From: Limin Wang
The test ffmpeg command in iMAC:
./ffmpeg -y -i input.ts -i ./logo.png -filter_complex
overlay=50:50:format=yuv420p10 -c:v hevc_videotoolbox ./test.ts
Now I have tested with 8bit and check the result is OK

[FFmpeg-devel] [PATCH] avcodec/hevcdec: set the SEI parameters early on the AVCodecContext
It's better to do it before the buffers are actually created. At least in VLC
we currently don't support changing some parameters dynamically easily so we
don't use the information if it comes after the buffer are created.

The same problem may exist with H264 alternative_transfer but I don't have a
sample to test with and the code seems a bit different.
