RK的6.1内核正式版应该还没发布吧，现在能下载到的应该是[几个月前的develop](https://github.com/friendlyarm/kernel-rockchip/blob/nanopi6-v6.1.y/drivers/dma-buf/heaps/Makefile)，里面的的dma_heap还没完工。 https://github.com/rockchip-linux/mpp/blob/ed377c99a733e2cdbcc457a6aa3f0fcd438a9dff/osal/mpp_runtime.cpp#L89 非要用的话mpp这里得改下了。 ```c allocator_valid[MPP_BUFFER_TYPE_DMA_HEAP] = !access("/dev/dma_heap/system-dma32", F_OK | R_OK) || !access("/dev/dma_heap/system-uncached", F_OK | R_OK) || !access("/dev/dma_heap/system-uncached-dma32", F_OK | R_OK); ```

ffmpeg's `frame_sync` utils only guarantees that frames are synchronized in timestamps, but does not guarantee that the underlying video data is synchronized.

Perhaps you need some calls from CoreImage to ensure the video data has been synchronized correctly, similar to glflush()/glfinish() in OpenGL.

Good catch. But i can still find some vibrating frames in this clip. Especially some frames at the beginning and end.
