Summary of the bug:
Memory leak on call **avcodec_flush_buffers()** when use **h264_qsv**
decoder in **Windows 10/11**.
For ease of reproduction, I simply took the official example
https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/qsv_decode.c and
added a call to **avcodec_flush_buffers(decoder_ctx)** in the read/decode
loop for every 10th packet.
For each call to avcodec_flush_buffers(), memory consumption increases.
Windows 11 24H2.
Intel UHD 730 with the latest drivers, no memory leak.
Intel HD 530 with the latest drivers, memory leak.
I agree that the Intel drivers are to blame here, but maybe something is
missing in the code in ffmpeg?
