"Attempting continuous hardware decoding for several hours or multi-channel decoding often results in the following error. Is this a normal occurrence?
[hevc_rkmpp @ 0x7f2c030d60] An invalid frame was output by a decoder. This is a bug, please report it.

Also, is the configuration method for RGA filters in the code the same as in original FFmpeg? I'm not very familiar with how to use filters."

What is the video codec and file container? Is the file local or remote (via what protocol)? Can you provide a sample for reproduction?

RGA filter is a hardware filter, which requires an extra step to set the hardware context. Other than that, it is similar to software filters in usage. Here is a demo for reference.

Thanks for your reply. I will study the filter part carefully.

From the logs, the video file is an HEVC (H.265) Main Profile stream inside an MP4 container, with the following details:

Codec: HEVC (hvc1)
Resolution: 1920x1080 (16:9)
Bitrate: ~6.5 Mbps
Framerate: 30 fps
Audio: AAC-LC, 44.1 kHz stereo
Source: Local file (3.mp4)
This problem also occurs on other videos.
I wrote a video playback library, but it is too complicated to provide a reproducible example.

Adjust ffmpeg's log level to verbose -v verbose. The next time a problem occurs, upload that log for further investigation.
