i had installed fresh armbian 5.20, and tested below command, the result was same:

to @lex, i wonder that is possible to use 720P(1280x720) 30fps on orangepi pc.
vdpau(cedrus) capable of this?

Hi,
Ah, my bsp is not armbian-based!

guvcview with gc2035 works fine, 1280x720p (12~20fps),
but this is not hw accelerated rendering.
https://github.com/avafinger/guvcview
and i couldn't set camera format

Yes, i read the post, but i think it is not related topic.
gc2035 works fine itself, i think this is not hw problem.
because, currently below command works fine with my OPI (real time but latency).
i built ffmpeg to enable ffplay.
sudo ffmpeg -f v4l2 -channel 0 -video_size 640x480 -i /dev/video0 -pix_fmt nv12 -r 30 -b:v 64k -c:v cedrus264 -f matroska - | ffplay - -
i followed to build mpv to support vdpau,
https://forum.armbian.com/index.php?/topic/1129-h265/
test.mp4 file works fine with my custom mpv, but still failed to open /dev/video0.

Hi, i am using orangepi PC (H3).
i had tried follow link, test.mp4 file created successfully. (video fine).
https://github.com/avafinger/ffmpeg_cedrus264_H3
now, i want to real time(20~30 fps) capture for /dev/video0 (gc2035).
i tried mpv with gc2035, but it didn't worked.
i want real time video capture using cedrus264.

[Solved] video capture (gc2035)

i think there is some bug for rootfs(or bootloader?) in armbian 5.30, because,
if i install armbian 5.20 and upgrade(apt-get update and upgrade and ftp.de.debian.org) to 5.31 and install manual built kernel and uboot, then gc2035 works fine.
but, if i install armbian 5.30(another SD-card) and install manual built kernel and uboot, then gc2035 doesn't worked.
