Segmentatin fault should be caused by my own code processing

Please provide a command line that can be reproduced with ffmpeg and a video sample.

I met maybe the same problem when I use the encoder "hevc_rkmpp". It broken with "Segmentation fault" before avcodec_send_frame, the gdb info show down here.

It could worked with the same code by using encoder "AV_CODEC_ID_H265".

Make sure you have built and installed the latest MPP runtime and headers. Otherwise undefined behavior may occur, such as segmentation fault. Be careful if you use MPP deb packages from a vendor/BSP image, these packages are likely to be out of date.

No it’s not related.

Closing as I couldn't get a sample.
