audio gain, and constant quality in client profiles
The ffmpeg command would be
-af volume= 0 to 10: 0 being no sound, 10 being the original max volume, then anything over 10 being the gain .
So -af volume=12 will increase the max volume by 2 (dB? not sure but it does increase it), the max value is 8.38861e+06 so I doubt it is in dB.
Also is it possible to specify the x264 preset, profile, level, and constant quality level?
I find with x264, setting a highbitrate of say 14000, but with a constant quality of around 20, I get about 1.7Mb bitrate, and reasonable quality....
If the some or all of the above are not possible, what would be great if it exists are all the vairables like maxHeight, maxVBitrate etc that are available and what they relate to in ffmpeg.
UPDATE:
Lol - the threads is selected in the serviio console - so never mind that part...
so ignore this:
Also setting the threads is useful in limiting the utilisation for the multi-thread capable encoders.
I am currently encoding using asf and wmv2 because the auto threads command doesn't work with this so the cpu utilisation is around 15% when using this to encode with, but the quality at low bitrates is not as nice as x264.
However if I use any other encoder, then CPU jumps up to 80 to 90% utilisation, which is just not what I want when sending a movie across wifi.
