Thank you @jfabernathy for confirming that sd4tvh works on the new RPi4. That is good news.

A new script.module.sd4tvh-0.3.4.zip has been released. Updates include:

• Add README file
• Add logging of number of station ids found
• Re-enable logging for LibreELEC

Personally I can attest to being able to record two OTA 1080i ATSC streams while watching another pre-recorded show using an older HDHomeRun Connect dual tuner with a Raspberry Pi 3 and LE 8.2.5.

From a quick look at the technical specifications section for the HDHomeRun CONNECT QUATRO it appears that the device has a "100 base TX high speed network" connection. As such a Gigabit Ethernet switch might not be necessary (at least for 4 streams), but will likely be needed since you are considering more than 4 tuners/streams.

I did some bandwidth math in the hardware selection section of my tutorial: Build a Cheap PVR using Raspberry Pi 3, LibreELEC, Kodi, Tvheadend, & HDHomeRun. In theory it should be possible to record four OTA 1080i ATSC streams concurrently using a "100 base TX high speed network" connection.

> I get a can't connect error from Firefox.

Do you have any Firefox Add-ons that might by default block the connection, such as NoScript? If so be sure to configure these add-ons to permit access to the IP address of your Tvheadend web server.

Recently I made some enhancements to fix problems with sd4tvh and LibreELEC (see GitHub Pull Request #3). These fixes have been successfully tested with LibreELEC 8 and 9. They are available in the current edit4ever git master, and script.module.sd4tvh-0.3.3.zip.

To check if a Raspberry Pi is using the MPEG2 codec license:

vcgencmd codec_enabled MPG2

The response if the license is in use will be something like:

MPG2=enabled

The red icon with a speaker and a cross indicates that sound is muted. To get sound again you need to press the mute button (F8 on keyboard) to toggle sound back on.

You might try placing up to 8 license keys all on the same line of one of your RPi microSD cards. For example:

decode_MPG2=0x8ff5a5c7,0xd4cb22af,0xe05b40bc,0xa54335b8,0x5964579b,0xafd24232

which is part of a tutorial I wrote.

Then you could boot each RPi with the microSD card and use the following command to check if the license is enabled.

vcgencmd codec_enabled MPG2

Note that I recently purchased an MPG2 license for a RPi3B+ and the process worked. I suspect that the RPi hardware doesn't magically recognize when a patent expires.

Thanks for posting your findings on MythTV and Kodi on the Raspberry Pi 4.

If you still have on old RPi3 then for a portable solution you might consider using that with LE 8.2.5, TvHeadend Server 4.2 (8.2.113), and sd4tvh 0.2.1 (HDHomerun Channel Filter: Discover). That's the combination I'm running and it's working well.

Quote from jfabernathy

I was just hoping the by using sd4tvh I could have this done all on one system and avoid the second computer running zap2xml.pl to create that xmltv.xml file

When I set mine up I only used the Raspberry Pi. I did not need to run anything extra on other computers, other than a web browser to configure Tvh that is.

Since you're not the only person who encountered difficulty getting sd4tvh to work, I suspect that something has changed since LE 8.2.5 and sd4tvh 0.2.1. Unfortunately this earlier version of LE doesn't run on an RPi4. You might try the combination that worked for LHoust in post 77.

Note that I encountered issues with LE 9.0.x wherein 1080i (interlaced) video did not play smoothly on my Raspberry Pi 2. Hence I stayed with LE 8.2.5. I think the issue was due to a change in Kodi 18.0. For more details see Installing LibreELEC 8.2.5 with MythTV PVR Client on a Raspberry Pi 2/3/3B+.

It's been a while since I last worked with the sd4tvh settings. If I recall correctly I had to manually add the EPG source for each channel Name under Configuration -> Channel / EPG -> Channels. Otherwise I recall that the grabber did not pick up any EPG information. This is configured from a web browser. For example 192.168.1.65:9981

What version of sd4tvh are you using?

I have an RPi3 installation running LE 8.2.5, TvHeadend Server 4.2 (8.2.113), and sd4tvh 0.2.1 and it is running well.

Regarding the black display have you tried both HDMI outputs on the RPi4? IIRC LibreELEC currently only supports video on the video output adjacent to the power port.

Have you tried both HDMI video outputs on the RPi4? If I recall correctly video is only supported on the output closest to the power connector.

> Audio runs fine, but I don't get any Video to run.

Have you tried both of the video outputs on the RPi4? IIRC video is currently only available on the one closest to the power port.

I don't have an RPi4, but I can confirm that at least one USB 3.0 HDD can be connected directly to the USB 2.0 port of an RPi3 (and also an RPi2 when I did a brief test). I've also had a keyboard, MCE remote control, and a USB flash drive all connected at the same time as the USB 3.0 HDD and all worked flawlessly.

With the larger power supply for an RPi4, it might be possible to connect two HDDs directly to the USB ports.

If you seek more details on how I used a USB 3.0 HDD with an RPi3, then see Build a Cheap PVR using Raspberry Pi 3, LibreELEC, Kodi, Tvheadend, & HDHomeRun.

I too experience video stuttering playback issues on a RPi2 with Kodi 18.x on LE 9.x with 1080i MPEG2 North American Over-The-Air TV content. The cause of the video stuttering appears to be a change in the default automatic deinterlacer to Adv(2x) in Kodi 18.x used in LE 9.0.2. On LE 8.2.5 with Kodi 17.6 the default automatic deinterlacer is Bob(2x). To work-around the issue you can manually select the deinterlacer from the in-playback kodi menu.

For now I have chosen to stay with LE 8.2.5 on my RPi2, as described in a tutorial I wrote: Installing LibreELEC 8.2.5 with MythTV PVR Client on a Raspberry Pi 2/3/3B+

'Hope that helps.
