build options for rpi

Post by white_haired_uncle »

https://www.mythtv.org/wiki/Build_from_ ... all_MythTV
For building version Master or version 30 for Raspberry Pi, change --enable-openmax to --enable-omx-rpi.
That sure looks like it's dated, and "master" probably should have been something like 31-pre or whatever since the author was probably talking about master at a certain point in time and not in general.

Hoping someone can clarify.

Also, does the same answer apply to "Raspberry Pi Ubuntu (not recommended)", and is RPU still "not recommended"?

TIA

I also agree that the Wiki for build from source for the RPI is out of date. That is why I put all my build guides on the forum. IMHO editing markdown files reminds me too much of DOS Word Perfert back in the early '80s. I get the shakes just thinking about it.

I have not updated any of my RPI forum post due to lack of interest in the RPI any more. I found that RPI4 could never be made to run mythfrontend close to what I consider good. When thinking about RPI5, I found that buying a 16GB RPI5 + nvme hat + PS + fansink + case was more expensive than buying a GMKtec N100/150 which runs mythtv including the frontend great. Since the N100/150 is x86_64 it runs all versions of Linux and any version of mythtv without much work.

All my RPI4s and RPI3s are is a box waiting to be used on some yet to be named home automation project.

Heresy! WP5.1 was the One True Word Processor. It's all been downhill from there. :-)

I'm pretty happy with my Pi MythTV box. I have a small screen (live in a camper) so maybe that's why I am not bothered by image perfection.

A question for you, since you seem to grok this stuff. My understanding is that MythTV-Light is about packaging simplicity rather than any pi-specific performance tweaks. Assuming one is willing to do the work, would MythTV from the repos be heavier, performance-wise, than the Light approach? Feel free to point me at existing documentation and yell "RTFM" if I've missed something obvious.

The latest instructions I have are from earlier this year for the RPI4 and version v34, but v35 version is also on the Google Drive. You could start there. It should work. See the post here:

viewtopic.php?f=46&t=5802

This post is about v34 but when you go to the google drive link you can go up a level and find v35.

If you want to build your own, note on the github mythtv packaging deb-light instructions that the default is now cmake, so if that doesn't work, change the option back to the old way.

https://github.com/MythTV/packaging/tre ... /deb-light

I'm not in a position to setup to try this at this time. I'm about to go on an extended trip and will not have my build stuff available.

I appreciate the guidance. Not married to the Pi so I'll also investigate one of the mini pcs. Thanks!

I downloaded your v35 build and did the install on USB3 to SATA SSD using a Rpi4 with 8GB RAM.
Works great! Even the frontend works to playback 720p and 1080i.
The hardest part was getting XMLTV and Schedules Direct working.
I pulled the USB3 and plugged into an Rpi5 with 4GB RAM and it worked great on it too.
Thanks for your instructions that have been very helpful over the years.
Looking forward to Trixie on Raspberry Pi and the next build.
