decoder error #41

Closed ywangwxd closed 6 months ago

ywangwxd commented 7 months ago

I followed the instructions, 1, compiled and installed mpp from git 2, compiled and installed libyuv from git 3, compiled and installed ffmpeg but when I try to transcode a video, it showed error message :

[h264_rkmpp_decoder @ 0x55d029d760] Picture format is nv12. [h264_rkmpp_decoder @ 0x55d029d760] Failed to initialize MPP context (code = -1). [h264_rkmpp_decoder @ 0x55d029d760] Failed to initialize RKMPP Codec.

I tried mpp_info_test binary compiled from MPP source, it shows nothing. What is the problem?

What kernel and linux distribution are you using? uname -a

ywangwxd commented 7 months ago

5.10.110 #39 SMP Tue Nov 8 11:08:57 CST 2022 aarch64 GNU/Linux

I am using ubuntu, I did the compliation on the aarch64 system directly, not cross-compiling.

could ypu try decoding with sudo, if it works you need to enable access to mppservice, rga, heaps to the logged in user, you can check udev rules below.

Yes, it is working if I change the input to a rtsp stream or a h265 file, but not on a mp4 file.
