- I've tested this serie on SM8650, first I failed to get HEVC working with the following command:
v4l2-ctl --verbose --set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 --set-selection-output target=crop,top=0,left=0,width=1920,height=1080 --set-fmt-video=pixelformat=HEVC --stream-mmap --stream-out-mmap --stream-from=Big_Buck_Bunny_1080_10s.yuv --stream-to=Big_Buck_Bunny_1080_10s.hevc -d /dev/video1
I got:
qcom-iris aa00000.video-codec: session error received 0x1000005: unknown
I checked the diff with v2, and reverting this make HEVC encoding work again:

Did I pass some wrong parameters ? I don't expect the fw to crash.
- On the 1280x720 output bug, I tried the same commands as v2:
v4l2-ctl --verbose --set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 --set-selection-output target=crop,top=0,left=0,width=1920,height=1080 --set-fmt-video=pixelformat=H264 --stream-mmap --stream-out-mmap --stream-from=Big_Buck_Bunny_1080_10s.yuv --stream-to=Big_Buck_Bunny_1080_10s.h264 -d /dev/video1
And I still get a 1280x720 h264 video, did I miss something ?
- Finally I tested the firmware you sent today (https://gitlab.com/kernel-firmware/linux-firmware/-/merge_requests/654),
first thanks a lot for that !
But then I was unable to encode with this firmware (v2 or v3 patchset), I got around all the firmwares
I got and here's the results:

The change occurs around Aug 14 2024, So I checked the downstream driver and I found that fixes the encoding:

And I checked and encoding still works with the "old" firmwares.
With both changes, I can get H264 & HEVC encoding working on any firmware.
