[mythtv-users] Raspberry Pi - Packaging with Open GL enabled

[ted.thom at yahoo.com]

Hi all!

I have been trying to get the latest Raspberry Pi (on Raspbian) enhancements (https://github.com/MythTV/mythtv/commit/5f200bf4b6a85da0c2a6a659312667de1e5ac4e8) on fixes/0.28. I am very much looking forward to seeing the OpenGL-rendered OSD :-) [Thank you Peter]

I am building MythTV using the packaging scripts (https://github.com/MythTV/packaging/tree/fixes/0.28/deb), but I am not able to get the OpenGL OSD working so far. I will explain the error I was getting when running the packaging scripts with opengl enabled, the change I made to the packaging scripts in order to solve/work around it (not sure that solve is the right word :-) ) and finally the error I am seeing when trying to display a OSD element using OpenGL.

1. I started by updating the configure parameter by adding the values Peter advised in order to enable OpenGL: "--disable-opengl-video --disable-vdpau --enable-opengl --disable-opengl-themepainter --disable-vaapi". The error I was getting when running the packaging script was happening when the dh_install command was ran. The error I was seeing is:

----END OF LOG EXTRACT----- 

2. Getting passed this error: I looked at why it could be happening and what the error messages meant and after experimenting I was able to pass through this error by adding the line "usr/share/mythtv/lib" to mythtv-common.install (it worked also by adding it to mythv-frontend.install) [I am not sure if this is the right way to solve the error I was getting]. [At the same time I looked at the master branch (of the packaging project) ad ported a couple of changes that I believe had not been ported (I don't think these are affecting the problem I have seeing and that I will describe below)]. Anyway, the result of the changes I made to packaging/fixes/0.28 are in this diff: https://github.com/MythTV/packaging/compare/fixes/0.28...teddythomas:fixes/0.28-rpi?expand=1

3. The packaging now goes through, but I am not able to have the menu appear properly when selecting the OpenMAX High Quality profile.
It looks like MythTV is able to read the OpenGL library properly because in the mythfrontend logs I see:

But once I launch a video and try to have a menu appear on the screen (typing M for example to make the menu appear), I see the following errors in the logs and no menu is appearing:

If anyway of you would have any input if I am doing something wrong in the packaging script or if anyway of you have any idea about what could be happening, that would be very helpful, because I am kind of stuck :-)

Thank you in advance for your help and thank you Peter for the enhancements you keep bringing to the Raspberry PI support.
