ffmpeg transcode hang up #42

Closed ywangwxd closed 9 months ago

ywangwxd commented 9 months ago

I followed the instructions to compile ffmpeg with rockchip libarary. But when tried transcode a video such as

sudo ffmpeg -i 428cut.mp4 -c:v h264 out.mp4

the process is hanging up, I did not see any cpu loading for this process. It seems to wait for a key input, but when I press any key, it did not have any reaction, enven for q.

what is the problem?

do you get any errors in kernel log when this happens? dmesg output pls.

ywangwxd commented 9 months ago

Yes, I can see error in dmesg output.

these errors are irrelevant as they are related to wifi, not ffmpeg or rk3588 VPU

great9 commented 9 months ago

try running it with strace and see where it stops / locks up

ywangwxd commented 9 months ago

After I changed the input from mp4 file to a h264 raw stream file, I could decode it into images, transcoded it into another h264 or h265. I checked the resulted images from h264 decoding, seems all right.

But I got another problem. I could not decode the resulted H265 file into images. The transcoding process showed success. But the decoding into images showed errors:

By the way, what I should do if I want to transcode a mp4 file?

ywangwxd commented 9 months ago

If I decode another h265 file downloaded from web, it seems ok. So the problem seems to be the transcoding.

ywangwxd commented 9 months ago

After I changed to input a h264 file or a rtsp video stream, transcoding is working.
