live: Set options as for live transmission. In this mode, you shouldsend by one sending instruction only so many data that fit in one UDP packet,and limited to the value defined first in payload_size (1316 isdefault in this mode). There is no speed control in this mode, only thebandwidth control, if configured, in order to not exceed the bandwidth withthe overhead transmission (retransmitted and control packets).
SMPTE VC-2 (previously BBC Dirac Pro). This codec was primarily aimed atprofessional broadcasting but since it supports yuv420, yuv422 and yuv444 at8 (limited range or full range), 10 or 12 bits, this makes it suitable forother tasks which require low overhead and low compression (like screenrecording).
The suggestions are based on the recommendations of the DTAGstreaming experts for live room correction, i.e. they weregenerated from manual room correction of data pursuant to DTAGtestbed 33, which in turn was based on a manual room correction of Datatest 12. If the ffmpeg version you are using is not one in which DTAGrecommendations are implemented, then you may need to tweak thesettings yourself. 7211a4ac4a
