Hello Linjie, there is little different between vaapi_hevc and other vaapi codecs. vaapi_hevc has an extra code block to handle slice buffer before ff_vaapi_decode_issue() , and if it's failed to handle, the buffers have to be destroyed separately. So the calling of ff_vaapi_decode_cancel() here is a must for hevc. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
