Andreas Rheinhardt d2bc039501 avcodec/error_resilience: Make applying decode_error_flags optional Add a pointer parameter that if supplied will be used to return the updated decode_error_flags. This will allow to fix several races when using frame-threading; these resulted from AVFrame that the earlier code updated concurrently being used as source in an av_frame_ref() call in the decoder's update_thread_context.
