Is there a way to adjust FFMPEG preset value?

[smirk]

Hi, I'm streaming h.264 to my PS3, and the picture looks great. However, for certain things (like scrolling credits), the bitrate skyrockets and my network can't keep up. (By "skyrocket", I mean that it jumps from an average of 5 Mbps to 65 Mbps). By comparison, Plex's DLNA server uses about 3 Mbps for the same video.

I was thinking that since my CPU is underutilized, it might be helpful to adjust FFMPEG's `preset` setting to something that compresses slower but better. Is there a way to adjust UMS' FFMPEG values?

Thanks!

Hi,

yes, you can find them in our Wiki or into you DefaulRenderer.conf file.

# Overrides the FFmpeg custom options in UMS for this renderer. Default is
# empty, which means the UMS settings will be used.
# All setting for output formats, codecs, bitrate e.g. can be used except video,
# audio and subs mapping (-map).
# Do not use it to override -vf; use OverrideFFmpegVideoFilter instead.
# Default: ""
CustomFFmpegOptions =

And many more

By default UMS use:

Code: Select all

 -preset ultrafast
