Hi
Could anyone explain me what is "raw" encapsulation method . I am actually trying to stream a MJPEG video over UDP . Even though, I have selected the bitrate as 64 kbps in the transcoding options and the encapsulation method as TS , the VLC statistics show the streaming bitrate around 1100 kbps . I need to stream over a very low bandwidth channel ( around 100 kbps) , can anyone suggest how can i do this ?

Thanks

Raw means there is no shim between MPEG-TS and UDP header, while normally you would use RTP in-between.

Thanks for replying .. But could you explain it a but more in detail . At presenet mpeg-ts over udp packs 7 packets of the Ts-stream into one UDP packet ( assuming MTU=1500 bytes) . How would this change using "Raw" method , and how can i use the "raw" method for streaming ?

Raw encapsulation is what #std or #standard gives you (contrary to #rtp).

I am getting a bit confused now . There is an option of mux=ts or mux=raw . What is the difference between this ?

If you're talking about RTP, then raw means emitting each ES as a separate RTP session (on a separate port), whereby TS means everything is multiplexed with TS over a single RTP session.

However, raw usually refers to not using RTP at all.

Thanks a lot.
