Magic command line for VLC/JTVLC in 16:9 format in Ubuntu or Linux Mint

[georg]

Hi,

after fiddeling around for a while I succeeded to get VLC+JTVLC working under Ubuntu/Mint with audio working and synced for 16:9 video, including a logo. The magic command line is:

vlc -I dummy v4l2:///dev/video1 :v4l2-aspect-ratio=16\\:9 :v4l2-standard=2 :input-slave=alsa://hw:1,0 --logo-file=/home/georg/Downloads/mvlogo.png --logo-x=800 --sout='#transcode{vfilter=canvas{width=320,height=1 80,aspect=16:9},venc=x264{keyint=60,idrint=2},vcod ec=h264,vb=100,acodec=mp4a,ab=32,channels=1,sample rate=22050,sfilter=logo,audio-sync}:duplicate{dst=standard{access=file,mux=mp4,d st=/home/georg/kumma.mpg}, dst=rtp{dst=127.0.0.1,port=1234,caching=2000,rtcp-mux,sdp=file:///home/georg/vlc.sdp}}'

Explanation:

- The stream is not shown (dummy interface). Instead it is dubbed into /home/georg/kumma.mpg.

- The sdp file and jtvlc work as described in the jtvlc-wiki.

- It is important to remove or disable the pulseaudio server in order to have a working alsa interface.

- The v4l2-standard=2 above is PAL, change it at your convenience. The video camera (over a Dazzle USB converter) must be 16:9 as well.

- It is well possible to increase the canvas size and the video bandwidth.

- Important parameters (not in the jtvlc-wiki) are rtcp-mux and caching=2000 in the rtp section. The rtcp-mux prevents the client from complaining about too many reference frames and/or too old video data. The caching=2000 is necessary to have synced audio and video. Without it, video will lag behind in the rtp stream (but not in the saved mpg file).

- Extra hint: When embedding the video in other websites, change the size of the object to 640x360 which is 16:9. So there will be no black bars.


VLC was 1.1.6 (current ubuntu package for videolan.org) jtvlc was 0.41

Have fun

Great post. I'll add my command to your list.

Linux Mint 12
Vlc 1.1.12
Jtvlc 0.41

Streaming a looping playlist with marque (title + time remaining) in the bottom right corner:

vlc --loop --sout-keep --sout='#transcode{soverlay,sfilter=marq{marquee="$t $L",position=9,size=10,opacity=255},venc=x264{keyi nt=60,idrint=2},vcodec=h264,vb=350,acodec=mp4a,ab= 96,channels=2,samplerate=44100,audio-sync,deinterlace{deinterlace=linear},threads=0}:ga ther:rtp{dst=127.0.0.1,port=1234,mux=ts,ttl=30,sdp =file:///PATH-TO-SDP-FILE}"}' "PATH-TO-XSPF-PLAYLIST-FILE"

I will add your "caching=2000,rtcp-mux" portion to the command and a few more input/output resolutions in a few days.

John Frank, I tried your vlc command:

vlc --loop --sout-keep --sout='#transcode{soverlay,sfilter=marq{marquee="$t $L",position=9,size=10,opacity=255},venc=x264{ke yi nt=60,idrint=2},vcodec=h264,vb=350,acodec=mp4a,ab= 96,channels=2,samplerate=44100,audio-sync,deinterlace{deinterlace=linear},threads=0}:ga ther:rtp{dst=127.0.0.1,port=1234,mux=ts,ttl=30,sdp =file:///PATH-TO-SDP-FILE}"}' "PATH-TO-XSPF-PLAYLIST-FILE"

It worked great for 2 days playing constantly when the files were all the same format/type. But when I added in some different file types, width/height, and bitrate, the viewer would go black when it switched to the next video. I would not mind at all pre-converting all my files, but everything I've tried has failed. Any suggestions?

thanks,
Paul

Found another that seems to have resolved that issue.

vlc --extraintf http "/PATHTOVLCDIR/Playlist.xspf" --loop --sout='#gather:transcode{venc=x264{keyint=24,idrint=2,cabac=0,bframes=0},vcodec=h264,vb=500,fps=30,scale=1,acodec=mp3,ab=64,channels=2,samplerate=22050,audio-sync,deinterlace{deinterlace=linear},threads=0,sfilter=marq{marquee="$t - $L",position=9,size=10,opacity=255},vfilter=canvas{width=640,height=360,aspect=16:9}}:duplicate{dst=rtp{dst=127.0.0.1,port=1234,mux=ts,sdp=file:///PATHTOVLCDIR/vlc.sdp}"}'

It's held up using different video formats + different resolutions.

Also should mention I'm using the daily stable vlc ppa. https://launchpad.net/~videolan/+archive/stable-daily

To add it:

sudo add-apt-repository ppa:videolan/stable-daily
sudo apt-get update

Also tweak the X264 settings within the preferences.

1) Preferences -> Input & Codecs -> x264 preset and tuning selection: Slower (slower results in a much better picture)
2) Preferences -> Input & Codecs -> x264 profile and level selection: High (Usually the default)

To ensure the best performance possible I recommend recompiling the latest stable vlc against the latest ffmpeg + codecs.

Here's a tutorial (with a few changes) based off this page: http://www.andrews-corner.org/vlc.html . I'm using Mint 13 (which is based off Ubuntu 12.04):

sudo apt-get remove vlc

Once newer versions come out adjust this script to reflect those changes and recompile.

I'll keep updating this post should I come across anything else.

I've been tearing my brain out trying to figure out how to stream. I'm not very technically or ubuntu savvy, is there an easier command or something I can use to simply stream the content of my left monitor and my sound so I can stream in ubuntu(12.04) so I can stop having to swap to windows when i want to stream?

Is there any chance any of you wonderful individuals can write a super noobie guide to get set up streaming in Linux/Ubuntu?
