Syncplay is not properly supported on Mac as none of the core Syncplay developers have a Mac. If you know any good OS X Python developers then please ask them to help resolve our outstanding OS X issues.

Only change in RC4 (compared to RC3):

  • Better handle VLC position reporting imprecision for all AVI files and for MKV files that have an incorrect or low framerate (VLC tickets #17658 and #17126). There may still be some issues with these files, but far fewer.

Notable bug fixes in RC3 (compared to RC2):

  • Updated Russian translation (by Corwin)
  • Add “edit playlist” option and  “add X as trusted domain” playlist menu options to playlist context menu
  • Increase folder timeout thresholds and reduce false-positives of folder timeout
  • Use “store and run” as default GuiConfig button unless –no-store switch specified
  • Improved shared playlist support (e.g. address bugs which caused files to switch unexpectedly or not advance properly, or erroneously set people as not ready when advancing)
  • Added support for Support for DESTDIR and PREFIX in Makefile (#114 by Hummer12007, fixing #110 by diogocp)
  • Fixed issues with VLC support and added VLC3 support (inc. #108 and PR #109 by Pilotat)
  • Fix issues with mpv dropping old ‘length’ property; needed for mpv >=0.23.0 compatibility (PR #120 by wiiaboo)
  • (mpv) remove remove scaletempo filter command line switch and more selectively disable verbosity (#106 by wiiaboo)
  • Prevent import error message from being displayed when GUI is disabled on systems without PySide (#117 by Hummer12007)
  • Prevent media player from re-opening same file on double-click from Syncplay UI, which caused rewind on some players
  • Fix double join message when entering a room with no file on servers with isolated rooms enabled (#123 reported by Corwin, fixed by Uriziel)
  • Improved support for Unicode URLs (issue reported by lyk)
  • Move to NSIS3 for improved security (resolves #121 by Armada651)
  • Fix issue with icons being misaligned in elements made taller due to text scaling
