Subject: [PATCH v3] avcodec/libx264: add warning log when droping picture at 'h264_select_output_frame'
since there is only debug log 'no picture ooo' when droping a picture,
I spent much time to troubleshooting a wrong sps 'num_reorder_frames' param changed by webrtc's 'ParseAndRewriteSps',
FFmpeg keeped silence about this error, so a warning log is much helpfull about this.
