Syncplay 1.5.2 Beta #3 – Enhanced mpv chat support

Posted by Etoh on January 21, 2018

Enhanced chat support for mpv is ready for testing.

You can e-mail us feedback via – if you want to comment on the mpv chat interface you can use

Features new in Syncplay 1.5.2:

  • You chat straight from mpv. By default you press enter, write your message, then press enter again. There is also an optional mode so you can start typing straight away.
  • You can how see multiple chat messages at once in a ‘chat room’ style or a ‘scrolling text’ style.
  • New ‘Chat’ tab in the Syncplay configuration dialogue. To get to this check ‘Show more settings’ in the normal dialogue.
  • (Experimental) Enter the commands from the command line interface mode straight into Syncplay by prefixing your message with “/”, e.g. “/u” to undo last seek and “/t” to toggle whether you are in ready mode.

Features new in Beta #3:

  • Fix to issue which meant non-US characters only worked in direct input mode
  • Added some additional Polish characters (thanks sztelke)
  • Those hosting their own server can now specify the chat message length they want using Add –max-chat-message-length (public servers have not been updated yet so still use the lower limit)

Known limitations:

  • You need to be using mpv >= v0.28.0 for the On-Screen Controller to be hidden during chat (e.g. to avoid it overlapping with the text input when it is positioned at the bottom)
  • Not all responses to /commands are relayed to mpv and only appear in the Syncplay notification window. If you want to fix this then feel free to make a Pull Request!
  • When running your own server you must specify a maximum chat message length through a command line option, e.g. –max-chat-message-length=125
