Failed to get key input frame from packet meta when encoding with h264_rkmpp encoder

[lumiaJJ]

Hi,
I am transcoding two streams with h264_rkmpp encoder. But I got an error when my program called av_hwframe_transfer_data before encoded the frame. This is an occasional problem， I got some information from this blog :https://brainly.com/question/43026554.
Can you help to analyze the issue from mpp extension's point of view.

[h264_rkmpp @ 0x7fa4015560] Failed to get key input frame from packet meta: -1
malloc(): unaligned tcache chunk detected

MPP log:

The MPP library itself contains some bugs. Use nyanmisaka/mpp instead.

nyanmisaka/mpp is already used to build MPP library, I will checked the version in my local tomorrow.

I can't reproduce with the command described in the Wiki. https://github.com/nyanmisaka/ffmpeg-rockchip/wiki

Can you share a minimal code sample that can be compiled?

#104 Hi, the issue might be related with this PR. You can enable MJPEG decoding to produced. And qsv_decode.c can be a a minimal code sample to test.
