Description

Installation and configuration notes

This multifunction card will run multiple recordings in parallel and provides BNC, TV, Composite and S_Video sockets.

The DVB and Satellite functions work flawlessly with mythtv-setup and mythbackend with no glitching once the firmware has been loaded. Please see the standard procedures for configuring these inputs.

The analogue inputs on the other hand present more of a challenge as there is no compression hardware on board. Mythtv-setup picks them up just fine and allows them to be configured using the v4l2 device type, but mythbackend is not capable of setting them up or streaming from them. See separate notes on using mythexternrecorder with v4l2 and vlc. Bear in mind that each recording channel will fire up it's own vlc compression and multiplexing process when it opens a channel to record or live play, so this approach is only possible with some fairly powerful hardware.

Most modern linux distributions will automagically load the kernel drivers.

At time of writing none of the firmware files are present in the stock Red Hat package (linux-firmware) so these will need to be downloaded separately and placed in /usr/lib/firmware (for RH based distros). For the purposes of this build they were sourced from GitHub at [1].

Boot time checks

Once you have fitted the cards, put the 3 firmware files in place, and cold booted, you should see something like the following in the system logs

Setup

Check to ensure the user that mythbackend runs as will be able to access the devices by adding that user to the "video" and "audio" user groups.

As that user use the dvb-fe-tool app to ensure that all is well with the DVB functionality:

# dvb-fe-tool

Then check the analogue functionality as the same user using the v4l2-ctl tool.

You should now be able to proceed to the standard setup process for DVB cards and the notes at mythexternrecorder with v4l2 and vlc on how to set up a non-compressing analogue card for mythexternrecorder noting which video and vbi device numbers were listed in the logs.

eg:

.... kernel: cx23885: cx23885[0]: registered device video0 [v4l2]
.... kernel: cx23885: cx23885[0]: registered device vbi0
