[FFmpeg-user] ffserver Unknown VideoCodec: libx264

[Ajay Parashar]

Hi,

I need to provide  a suitable output format for 'udp://226.0.0.1:1234.
now i removed MOV as it does not support seeking and start using mp4 but it says
"muxer does not support non seekable output"


What output format should i provide for sending h264 codec file?
please find logs as below
