-----------------------------------+----------------------------------
"Bitrate" function in udp out don't working if more than 1.35 Mbps on
Windows with differents versions of ffmpeg 5 6 7 and on Windows10
In live stream with codec libx264 or 265 or hevc_qsv or hevc_nvenc:
This fonction work properly with bitrate < 1350kbs With differents
computer or ffmpeg 5 or 6 or 7 the flow is always limited to 1350kbs with
bitrate > 1350kbs on windows.
Example: "-f mpegts -muxrate 2000000
udp://192.168.0.30&bitrate=2000000&overrun_nonfatal=1&fifo_size=262140&buffer_size=262140
I read that someone encountered this problem on Windows but not on Linux
but I can't test it
I try setting/increasing burst_bits without modification.
This fonction is need to test dvb experimentation with constant flow.
example with bitrate 2644506 bps analyse with TSReaderLite:
