 For Y4M transcode (lossless from uncompressed video files, only 8 bit):

 Verify uncompressed video using ffplay before encode to VVENC (important replace video size, otherwise it will not correctly show video, it's like scrambled eggs video):
 ```
-ffplay -i inputtranscode.yuv -video_size 1280x720
+ffplay inputtranscode.yuv -video_size 1280x720
 ``` 
 
 Default pixel format of ffplay for yuv and y4m is yuv420p without `-pix_fmt` command.
 
-For y4m videos, replace `-i inputtranscode.yuv` with `-i inputtranscode.y4m`. For yuv420p10 on your input video 10 bit, add `-pix_fmt yuv420p10`.
+For y4m, replace `-i inputtranscode.yuv` with `-i inputtranscode.y4m`. In `-c:v wrapped_avframe` for y4m only, so you can verify to play Y4M (wrapped_avframe) for VLC, FFplay or MPV player. For yuv420p10 on your input video 10 bit, add `-pix_fmt yuv420p10`.
+
+Playing ffplay for y4m video with wrapped_avframe, you don't need to put anything commands, just simple play this:
+
+```
+ffplay transcoded.y4m
+```
 
 For easy to verify YUV/Y4M, use YUView, open your YUV or Y4M encoded, make sure video size, YUV/Y4M format and frame rate same like from input video file (e.g. MP4, AVI, MKV and others.
