Streaming limit

Dear all

I have a Question, is there a streaming speed limit? I used the vlc player as a sever and streamed a h264 content with 12 Mbit/s and it worked but with warnings like

Code: Select all

number of reference frames exceeds max (probably corrupt input), discarding one number of reference frames exceeds max (probably corrupt input), discarding one libdvbpsi error (PSI decoder): TS discontinuity (received 13, expected 0) for PID 0 libdvbpsi error (PSI decoder): TS discontinuity (received 13, expected 0) for PID 66
when I tried an other video with an higher bitrate about 19Mbit/s there is only a black-screen at the client side and also warning like that

Code: Select all

number of reference frames exceeds max (probably corrupt input), discarding one number of reference frames exceeds max (probably corrupt input), discarding one libdvbpsi error (PSI decoder): TS discontinuity (received 13, expected 0) for PID 0 libdvbpsi error (PSI decoder): TS discontinuity (received 13, expected 0) for PID 66
but also a new one

Code: Select all

main warning: trying to send non-dated packet to stream output! main warning: trying to send non-dated packet to stream output! main warning: trying to send non-dated packet to stream output!
All warnings are server-side warnings. What is the Problem, is there a limit in the bandwith? Is there a possibility to raise it?

This is probably a CPU limitation.

I tested it on seperate systems and all with the same result 12 Mbit/s are good, the vlc player is working and 19 Mbit/s not and the difference between the systems is enormously. I tested it with the normal vlc player and the libvlc on all systems, all the same. And the utilization of the best system with the 19 Mbit/s stream was 40% of CPU and 10% of RAM. I tested it in network and on localhost, all the same.

Was one CPU peaking?

OK, can you increase the input cache?

input cache of vlc? I don't know how to increase it.
