 Summary of the bug:
 Hi all, I'm trying to support sending the HEVC stream to SRS server by
 RTMP protocol. And I used ffplay to get the stream from SRS. The command

 ffplay rtmp://

 ( is my SRS server IP and port)
 The stream source which I send to SRS is created using the China hisiv
 high video embeded system. I've modified the code of ffplay to support
 HEVC by RTMP protocol. And I'm sure that the data from SRS is correct,but
 I just got the problem :'''[hevc @ 0xad240480] Could not find ref with POC
 [swscaler @ 0xbbceb40] deprecated pixel format used, make sure you did set
 range correctly'''
 and the video shows nothing but grey.What could make this happen?

 The ffmpeg release is ffmpeg-4.1.
