Raspberry Pi deinterlacing

[pgbennett]

There has been a problem for some time with hardware deinterlacing on Raspberry Pi. The problem arose starting with firmware version #897, released July 8 2016. There is now a fix in MythTV.

MythTV versions prior to v0.28.1-34 will deinterlace correctly with firmware versions up to #896. MythTV versions v0.28.1-34 on will deinterlace correctly with firmware versions #897 and higher.

You can check your firmware version with uname -a

You can upgrade your Raspberry Pi jessie firmware to the latest stable version using "sudo apt update" and "sudo apt dist-upgrade". Currently this will install version #998.

I have updated the package download of MythTV-light so that the new version will be downloaded.

If you have previously changed your deinterlace setting to get around the deinterlace problem you can change it back to "Advanced(HW)" for the best results after installing the latest versions of MythTV and firmware.

Peter,

Not directly associated with deinterlacing fix.

I am running latest master, and have just installed mythtv-light and mythplugins-light on a clean install of latest Raspbian (#998) on Pi 3.

I needed to install libvdpau1 and libva-drm1 before the mythnews and other plugins show in mythfrontend.

Thank you for pointing that out. I have investigated and I found that i was building mythplugins with the wrong options. I will post a new version in the next day or two that does not need those libraries. They are not relevant to the raspberry pi setup.

I have released a new build of plugins that does not need those libraries.
