live streaming command line problem

Postby video_streaming » 16 Mar 2012 22:41

hey guys
im trying to initialize a live streaming on the server to the client (the both machine are under ubuntu 10.10). it works fine when i use the GUI method .
BUT when i use the command line , it doesnt work :/
im trying this code :

Code: Select all

vlc v4l2:///dev/video0 --sout '#transcode{vcodec=mp2v,vb=400}:standard{access=udp,mux=ts,dst=192.168.1.107:1234}'
Nothing appear in the client machine !!
Note that streaming a video on both ,GUI and command line methods, works.
any suggestion please ??

You're probably missing some parameters that the UI added.

Hey Remi

VLC 1.1.5 vs 2.0.1

Postby realjobe » 20 Mar 2012 07:11

Hi there.
Some commandline improvement has happened, because my Commandline does not work anymore with VLC 2.0.1.
2.0.0 works, but with stutter, cacheing and tearing..

Code: Select all

vlc.exe -I dummy --audio-language=fi http://192.168.0.251:8001/1:0:1:11:3:F:FFFF0000:0:0:0: --sout "#transcode{threads=auto,audio-sync,soverlay,deinterlace,ab=96,samplerate=44100,channels=2,acodec=mp4a, vcodec=h264,width=640,height=360,vfilter="canvas{width=640,height=360}",fps=25,scale=1,vb=160,venc=x264{keyint=250, preset=faster,level=-1,profile=baseline,cabac=1,slices=8,qcomp=0.6,vbv-maxrate=160,vbv-bufsize=80}}:rtp{mp4a-latm,sdp=rtsp://:554/TV.sdp,name="C"}" :no-sout-rtp-sap :no-sout-standard-sap :ttl=128 :sout-keep
Sourceside indicates quick stream request, but halts quite after..
Can some one tell me what's wrong with above? Works perfectly with VLC 1.1.5

I guess you need to use -- instead of :.

Codec is experimental but experimental codecs are not enable

Postby realjobe » 20 Mar 2012 16:29

Something is off here..
with (VLC 2.0.1 on win7_x64) VLC Crashes moments after with

Code: Select all

..[0317ac30] avcodec encoder debug: libavcodec initialized (interface 0x360a64)m ain input debug: Buffering 19% [NULL @ 031466a0] Codec is experimental but experimental codecs are not enabled, see -strict -2 [003cca10] [main input debug: 0Buffering 21%317ac30] avcodec encoder error: cannot open encoder[003cca10] main input debug: Buffering 23%[0317ac30] main encoder error:
With VLC 2.0.0 commadline works ok, but now there are bufferings on client side and stuttering...
What to Add to commandline in order to make this work with VLC 2.x?
caches and mux cache ? how? commandLine helps are to VLC 1.0.
