I am wondering about the mux caching if it really is working at all?

I am streaming to wowza media server and I am getting a few "late buffer for mux input" errors at times. And even if I don't get errors wowza very often reports about "incomplete NAL unit" which means something is wrong somewhere...

I thought increasing mux-caching would help, but I don't notice any difference at all changing it to whatever value. Sholdn't caching introduce a delay?


I am using following command in windows xp sp 3 with vlc 1.05 on a fast system with core i7 960 and cpu is under 20%

vlc.exe --sout-mux-caching=5000 --sout-transcode-high-priority -vvv -I rc dshow:// :dshow-vdev="Decklink Video Capture" :dshow-adev="Decklink Audio Capture" :dshow-caching=1500 :dshow-chroma=UYVY :dshow-fps=25 --sout #transcode{venc=x264{hurry-up,cabac=1,keyint=50,level=3.0,profile=main,bframes=3,me=hex,merange=20,subme=9,vbv-maxrate=1000,vbv-bufsize=7000,vbv-init=0.9,qpstep=3,trellis=1}vcodec=x264,vb=900,scale=1,acodec=mp3,ab=128,channels=2,samplerate=48000,audio-sync,vfilter=deinterlace}:rtp{caching=2000,mux=ts,port=10000,dst=192.168.0.10}}

Thanks for any help!

sout-mux-caching doesn't work.

so... are these all cache & mux stuff nessessary?

There is something off with VLC win32 2.0.1..
I can't make transcoding to work, with 1.1.5 it worked great..

Hello
i have some problems whith caching. I am under linux (whithout gui) and i would like enable cache on the client. In other words make a buffer on the client : pré chaging a part of the mp4.

I don't really unserstand where i have to put the caching argument : on the web page or on the server comamnd ?

I use the command : cvlc --sout-mux-caching=5000 "/home/Bob/Myvideo.mp4" --sout '#transcode{vcodec=mp4v,vb=800, samplerate=11250}:rtp{sdp=rtsp:192.168.0.60:8080/, sdp=rtsp://192.168.0.60:8081/test.sdp}'
