I'm trying to setup rygel to stream live tv using a Hauppauge USB Live 2. I can't get the setup for the mux. I would like to use mp4(m4v) as it seems to need less buffering on the client.
This is my command line for both video and audio (it works)
gst-launch-1.0 v4l2src device=/dev/video0 ! queue ! videoscale ! video/x-raw,width=720,height=480 ! videoconvert ! autovideosink alsasrc device=hw:1,0 ! audio/x-raw,channels=2,rate=48000,depth=16 ! audioconvert ! autoaudiosink

I cannot find and do not know how to modify this command to encode the video and audio to sink into a mp4mux for streaming over the rygel dlna server.

I found this youtube video which works with the right hardware.

This method would use a lot of cpu and add a latency not necessary if using the v4l2src.

Below is the format for the video capture card.
ski@mediactr:~$ v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'YUYV'
Name : 16bpp YUY2, 4:2:2, packed

I do have a v4l-ctl command to set the card parameters so that output in above command line and ffmpeg works.

The reason for wanting this is to stream the output from my Dish network 2nd tuner to other parts of the house. Houses here are built of cement so running cables is !!!!!! The 2nd tuner remote is UHF and reaches from most of the house so no ir channel changers or special channel software is needed.

I got a working system by making the changes to the example from https://www.youtube.com/channel/UCzl...3w-oofdFC4C9fQ. I changed the source sinks to the following command line.
ximagesrc-launch=asfmux streamable=true name=muxer v4l2src device=/dev/video0 ! queue ! videoscale ! video/x-raw,width=720,height=480 ! videoconvert ! avenc_wmv1 bitrate=4000000 compliance=strict ! muxer. alsasrc device=hw:1,0 ! audio/x-raw,channels=2,rate=48000,depth=16 ! audioconvert ! avenc_wmav1 bitrate=128000 compliance=strict ! muxer.

I am using XBMC as the client which has a short latency. Acceptable. I do have a problem when the client is shut down and restarted. Alsasrc device hw:1,0 is not found unless I restart the server. Working on solving that problem.

I got a reasonably working system.
I disabled all Rygel plugins except gst launch and used the above command line. V4l-ctl needs run with the parameters for the Hauppauge device before starting Rygel.
I setup a Raspberry pi 2 with Raspbian Wheezy lite, xfce desktop and all gstreamer1 codecs. Then installed Kodi and setup as a dlna client. (OpenELEC and Xbian did not want to run smoothly)
Sound still cuts out intermittently so am still looking for a mux that may work better.
I tried gupnp and gmrender-resurrect but couldn't resize the window.
