[FFmpeg-user] Parsed_pan_0 This syntax is deprecated. Use '|' to separate the list items

[Kimio Miyamura]

Hi list members!

I'm trying basic Movie playback with ffplay.  When I execute the following command, I got the warning "Parsed_pan_0 This syntax is deprecated. Use '|' to separate the list items".
What this waring mean and how should it be?

I have searched ffmpeg documentation on the net but I can't get the answer!


$ ffplay -i ~/Movies/More\ Than\ You\ Know.mp4 -af "pan=stereo:FL<FL+FC+BL+SL:FR<FR+FC+BR+SR"
