Two or three weeks ago I noticed a problem with parole on my latest
build on my haswell (LFS from 25th July, BLFS from the next day).
Whatever I try to view, the screen broken into horizontal stripes,
rather like venetian blinds but with a mix of colours not apparently
related to the video which should be visible.
On a machine using radeon (R600-series) video, parole works fine.
On my haswell, the following all work fine: ffplay, gst-play-1.0,
vlc.
Other things have, of course, got in the way, but I'm now ready to
document what has changed between working and broken versions, and
to ask for suggestions.
Looking back at previous builds on this machine, a build in May was
fine, the intermediate build in June showed the same problem.
The following packages, and versions, are common to both the good
and bad builds: running kernel 5.7.2, gcc-10.1.0, gstreamer-1.16.2,
fdk-aac-2.0.1, freetype-2.10.2, lame-3.100, libtheora-1.1.1,
libvorbis-1.3.7 (I upgraded older systems to that version),
libvpx-1.8.2, opus-1.3.1, x264-20200218, yasm-1.3.0, libvdpau-1.4,
libvdpau-va-gl-0.4.0, SDL2-2.0.12.
Looking at what had changed:
ffmpeg 4.2.2 on previous good systems, 4.3 and 4.3.1 on current.
libva-2.7.1 on last working system and on June non-working, 2.8.0 on
latest.
x265 3.3 on working, 3.4 on latest (now reverted to 3.3, symlink
fixed, gst-plugins-bad rebuilt)
intel-vaapi-driver 2.4.0 on good, 2.4.1 on latest, now reverted to
2.4.0.
xf86-video-intel 20200218 on good, 20200518 on latest, now reverted
to 20200218.
Before Bruce asks: I've used the same CFLAGS, CXXFLAGS throughout
these builds.
At this stage, this is just a request for suggestions, and a
question whether parole is working on anyone's current intel
machiens with integrated graphics ?
TIA

I would say that I was able to get Parole working, but unfortunately I'm
not able to:

When I launch Parole, it crashes with a segmentation fault. This is on
my Intel system, with Mesa-20.1.5, gst-*-1.16.2 of course, and
libxfce4ui-4.14.1 with the rest of the stack.
I'm not sure what's causing this.
Ken, you are able to get it to start at least without a segfault, right?
I'll be building this on my elogind system later, will verify that it
works there. Maybe it's something with the Iris driver. I'll research
how to back down to i965 to see if I can fix it that way, but it's
acting like its elsewhere.
