Hi,
Just a little background first, I was unable to use my own compilations of Kodi 18 on PiZero and Pi2B because the video playback on normal MPEG4 1080p streams was stuttering. Normal meaning some 6-7 Mbps streams, mainly from DVB sources (TS) and not very lossy video files in the range of 2-4Mbps.
Details here:
https://forum.kodi.tv/showthread.php?tid=341002
The same goes for the official LibreELEC builds, which I constantly downloaded & loaded & tried up until 9.2.3. LibreELEC 9.2.4 (Kodi 18.8) finally plays everything smoothly and I went on investigating the changes on github (commits). Stumbled upon this:
https://github.com/LibreELEC/LibreELEC.t...d0ae3b27ed
And learned that it was the Raspberry provided mesa libs that were causing the issue. (BTW, thanks @HiassofT for finding this out!).
I'm using a stable version of ARM Linux, built soft float (for compatibility reasons), with an older mesa-11.2.2 that I had to rebuild to enable the vc4 driver. I considered building an actual mesa (20.x), but rebuilding all its dependencies (newer versions of the libs) is something I wouldn't be very happy with on these little Raspberry devices, it'll take ages.
I built ffmpeg externally (shared), linked to the Raspberry userland (/opt/vc) for OMX&MMAL and commenced building Kodi 18.8 the way LibreELEC folks are doing now for the Raspberry target, using the system default mesa drivers, with the build directives: -DCORE_PLATFORM_NAME=gbm -DGBM_RENDER_SYSTEM=gles
This is how I started the Kodi 18.8 compilation for the PiZero - armv6 target:
- first I had to adapt (softfloat) the cmake/scripts/linux/ArchSetup.cmake
set(NEON_FLAGS "-mcpu=arm1176jzf-s -mtune=arm1176jzf-s -mfloat-abi=soft -mfpu=vfp")
- then:
This is how the compilation crashed:
And this is one of the relevant commits I found on google. The "improvement":
https://github.com/xbmc/xbmc/pull/14772
Wondering now how or if I'd be able to disable all this debugging stuff. Or, maybe I don't even need EGL on Raspberry (VDPAU & VAAPI are anyways disabled) and could provide a cmake directive to ditch it (don't know how).
Any help appreciated.
