Hi Pavel, Thiago, 

Thanks a lot for your quick response...

What about playback-compression?

I'd like you to help me to understand theese parameters:
  • streaming-video=<all|filter|off> Set video streams detection and (lossy) compression (default=filter)
  • playback-compression=<on|off> Set playback compression, using the CELT algorithm (default=on)
Thanks a lot!

It requires some testing on your side, you can start with these
"aggressive" settings:
image-compression=glz
jpeg-wan-compression=always
zlib-glz-wan-compression=always
streaming-video=filter
