Hello. I am trying to find a way to decode h264, h265 videostreams on the gpu. with ubuntu. I am not good with c and c++. I was hoping to find a way to do it using ffmpeg, gstreamer etc.

Hello @Berk_Guvercin

We suggest you to wait for the new 5.15 kernel in Q3, it will have better support for hardware decoding & encoding.

Hello @numbqq, in fact, I have successfully used default h264 plugins (avdev_h264) of Gstreamer to decode and get the video stream in python, but I don’t know how to find and use the hardware decoders that come with vim3 Amlogic.

Hello @JJ1997

Gstreamer hardware decoding plugin doesn’t work well with 4.9 kernel, you can wait for our new 5.15 kernel in Q3. Or you can try to use hardware decoding with other api: VIM3/3L Hardware Decoding [Khadas Docs]
