I’m installing Gstreamer as shown here: http://www.onepitwopi.com/raspberry-pi/gstreamer-1-2-on-the-raspberry-pi I’ve got shows I’m recording via tvheadend and would like to encode them into something in a reasonable size, such as an mp4. I’ve tried having tvheadend encode as it records but it ends up eating up all the RAM on my Pi 2. So I resorted to passthrough, but now I’ve got a 6.5GB .ts file for a single hour of HD video. I’m basically trying to replicate what this guy is doing: Hardware Video Encoding progess with the Raspberry Pi | Blank's Tech Blog
In his gst-launch command he’s using “omxh264enc” as the encoder, but I don’t have that one available to me, apparently. I tried installing omxplayer from source and the re-installed Gstreamer (via the script in the first blog post) but still don’t see any of the omx codecs available. The full list should look like this: http://theiopage.blogspot.com/2013/04/enabling-hardware-h264-encoding-with.html (This blog post is from 2013 and talks about Gstreamer 1.0 so I didn’t use those install instructions, I used the new ones in the first blog post.) The actual error I get when running the command:
osmc@osmc:~$ gst-launch-1.0 -e filesrc location="raw_video.ts" ! tsdemux ! mpegvideoparse ! omxmpeg2videodec ! deinterlace ! videoconvert ! omxh264enc inline-header=true periodicty-idr=1 ! "video/x-h264,stream-format=byte-stream,profile=high,control-rate=variable,target-bitrate=5000000,quant-i-frames=250" ! h264parse ! mp4mux ! filesink location="output.m4v"
WARNING: erroneous pipeline: no element "omxmpeg2videodec"
And then exit back to prompt.
omxplayer is included by default in Raspian and that seems to be what most of the articles are using as the OS when doing this Gstreamer work. Of the articles I’ve come across I haven’t seen anyone using it in OSMC.
Any ideas?
You will likely need to compile gstreamer with an option such as --enable-openmax when you run ./configure.

Here’s the full install script. I don’t see an explicit --enable-openmax flag set anywhere, but the second blog post refers to this script as the one he installed and he didn’t mention any problems with omx…

Hi
Skimmed this quickly. Guess would be gst-omx is a plugin / module. It may not be building properly if you don’t have the OSMC development packages.
sudo apt-get update
sudo apt-get -y install rbp-userland-dev-osmc
