Raspbian OS updated to Buster

Post by MikeB2013 » Mon Jun 24, 2019 4:23 pm

With the release of Raspberry Pi 4, the default Raspbian version is now Buster for ALL Pi models.
The normal download page is at https://www.raspberrypi.org/downloads/raspbian/

mythtv-light current 30 release is only supported on Stretch, so the Raspbian Stretch image is still required until mythtv-light is updated, which also means no mythtv-light on Pi 4 at present.

Older Raspbian images are available at http://downloads.raspberrypi.org/raspbian/images/

Hmmm - good ideas always translate into hard work :(

I guess I need to look into Buster. I have no raspberry pi 4 so it will have to be built on rpi 3 for now.

Peter,

I have a pi 4 (4GB RAM version) arriving tomorrow and will try a mythtv master build from source.

The graphics part is going to be interesting, to quote from the pi 4 blog https://www.raspberrypi.org/blog/

"One notable step forward is that for Raspberry Pi 4, we are retiring the legacy graphics driver stack used on previous models. Instead, we’re using the Mesa “V3D” driver developed by Eric Anholt at Broadcom over the last five years. This offers many benefits, including OpenGL-accelerated web browsing and desktop composition, and the ability to run 3D applications in a window under X. It also eliminates roughly half of the lines of closed-source code in the platform."

Also from the raspberry pi forum https://www.raspberrypi.org/forums/view ... 2#p1483965

"One big change on the Pi4 - there is no HW support for MP2 or VC1. These are both now decoded in software with the more powerful ARM cores. . So you don't need a licence."

Let me know how it goes.

Regarding MPEG2, that already works with software decoding on Pi3 and even on Pi2, if you don't have a license. So that should work fine.

I don't know about the new graphics and OpenGL - there may be opportunities to improve the rpi support there.

Have built fixes/30 using mythtv/packaging/deb-light on a pi3 running stock Raspbian buster with everything on an SSD.
Although I have also built mythplugins, don't bother, does not install due dependency problems (Depends: python-imaging but it is not installable as it is not available on buster).

It basically works on both pi 3 (still uses openmax) and pi 4 (uses vc4-fkms-v3d).
For pi 3 normal configuration applies, apart from Audio which I have at default of ALSA:default:CARD=ALSA, Video set to OpenMax.
For pi 4 which is connected to a 4K TV, I had to drop the screen resolution to 1920x1080 @50Hz, Audio at default, Video set to Normal or High Quality.

Edit 20190821
Official release of mythtv-light 30 for Raspbian Buster is now available see https://www.mythtv.org/wiki/MythTV_Light

Edit 20191001
My unofficial build is no longer available Dropbox link deleted.

Note I applied one patch to the build to get around the DVB-T/T2 Live TV issue in trac https://code.mythtv.org/trac/ticket/13292
The build also works into mythtv master backend at this time, as schemas are the same.

Download and then Install mythtv-light_30.0-60-gb9c1b41a6c-0_armhf_buster.deb as follows:

Code: Select all

sudo apt install ./mythtv-light_30.0-60-gb9c1b41a6c-dirty-0_armhf_buster.deb
This method of using apt resolves all the dependencies (sudo dpkg -i ...deb does not).

There were some issues with doing the build:
Could not use ansible (libcec4-dev not available) to setup the depends, so I installed manually as follows (includes mariadb):

Code: Select all

In my RPI3 running buster I cannot see the necessary defines for H265. Please can you look at your RPI4 and see if it is different there.

Code: Select all

cd /opt/vc/include/IL
grep OMX_VIDEO_Coding OMX_Video.h
This is what I get. I expect to see an entry for HEVC or H265 but there is none:

Code: Select all

    OMX_VIDEO_CodingMax = 0x7FFFFFFF

 *                       component. When OMX_VIDEO_CodingUnused is specified, 
This means I will not be able to build for RPI4 with hardware H265 decoding.

Peter,
Pi 4 uses OpenGL
From /boot/config.txt

Code: Select all

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

There is also another option to enable 4k "hdmi_enable_4k=1"

Attached is output of glxinfo -l on pi4

Also attached is glxinfo -l output from pi3 with dtoverlay=vc4-fkms-v3d enabled.

Hi just got my Pi 4

Trying to compare my results to yours. Your conclusion was that hardware decoding didn't work but software was ok. I can't get software decoding to work. The framerate is slow without the processors being loaded. Video playback in Chrome is the same, low cpu load and low frame rate. I understand that is the general state of the platform as the video libraries are yet to be optimized. Could you post the settings you are using for software playback including de-interlacing.

codec 'H.264' makes 'xv-blit,xshm,xlib,' available, using 'xv-blit' instead.


Hadware playback with Openmax high quality worked for me with improved quality to Pi 3B but still an unacceptable amount of jitter especially when panning. Interestingly turning off high priority interrupts in the video setting produced slight tearing.

On the pi4 I am running stock Raspbian Buster which uses vc4-fkms-v3d rather than OpenMAX, which I have not really tried, but from a quick look I don't see OpenMAX High Quality, only OpenMAX Normal, so it is possible I got the build wrong, I am looking into this it (it takes a while).

my pi4 is connected using hdmi-0 (the one nearest the usb-c power connector).
Setup screen resolution (Preferences>Screen Configuration HDMI-1) 1920x1080 @50Hz, I have it connected to 4k Television it defaults to 3840x2160 @30Hz.

Before running mythfrontend I changed the pi4 hostname from default of raspberrypi to something never seen by mythbackend, if mythbackend already has settings for the hostname these will be used, so it could try and setup a pi4 to use pi 3 settings.

In mythfrontend SetWizard I have
Audio Configuration Audio Device: ALSA:default:CARD=ALSA
Video Configuration Video Playback Profile: Normal (or High Quality)

In mythfrontend
Setup>video>Playback
Decoder Standard
Max CPUs 1
Deblocking filter ticked
video renderer xv-blit
OSD renderer softblend
Primary deinterlacer Linear blend
Fallback deinterlacer Linear blend

Theme is set to default i.e. MythCenter 1.4

I do see the odd problem with panning, mainly on HD channels.

@pgbennett

Peter,

I was having a look at why OpenMAX High Quality was not available in my build (I failed to notice OpenGL ES 2.0 was not being enabled).

Output of a test taken from configure gives the following, which explains why OpenGL ES 2.0 is enabled in Stretch but not Buster:
Stretch:

Code: Select all

pi@pi3-stretch:~ $ echo QTCONF=$(pkg-config --variable=qt_config Qt5Core || pkg-config --variable=qt_config QtCore)
QTCONF=minimal-config small-config medium-config large-config full-config release_tools gtk3 fontconfig libudev evdev xkbcommon-evdev libinput xlib xrender xcb-plugin xcb-render xcb-glx xcb-xlib xcb-sm accessibility-atspi-bridge gbm linuxfb kms c++11 c++14 c++1z accessibility egl egl_x11 eglfs eglfs_egldevice eglfs_gbm opengl opengles2 shared qpa reduce_exports clock-gettime clock-monotonic posix_fallocate mremap getaddrinfo ipv6ifname getifaddrs inotify eventfd threadsafe-cloexec poll_ppoll system-jpeg system-png png system-doubleconversion system-freetype system-harfbuzz system-zlib mtdev cups iconv glib dbus dbus-linked openssl libproxy xcb xinput2 alsa pulseaudio gstreamer-1.0 icu concurrent audio-backend release

Buster:

QTCONF=shared release c++11 c++14 c++1z concurrent dbus reduce_exports release_tools stl properties animation textcodec big_codecs clock-monotonic codecs textdate datestring doubleconversion eventfd filesystemiterator filesystemwatcher gestures glib itemmodel proxymodel identityproxymodel inotify library mimetype process statemachine regularexpression settings sharedmemory sortfilterproxymodel stringlistmodel systemsemaphore temporaryfile threadsafe-cloexec translation xmlstream xmlstreamreader xmlstreamwriter

As you can see a lot of things are no longer in Buster.

Is this something that can be fixed in configure or is it more more fundamental ?
I was expecting a single build to handle pi2/pi3/p4.

All the usual stuff is in /opt/vc/ on Buster.

On pi3 with buster I am also not getting openmax high quality, only openmax normal and a bunch of other options that are pretty useless. Openmax normal plays ok on the pi3. Does Openmax normal play with the pi4?

Possibly buster is set up for OpenGL rather than OpenGL ES. This may be the reason for ES being disabled.

I built fixes 30 using the following configure
./configure --enable-omx-rpi --disable-vdpau --disable-opengl-video --enable-opengl --disable-opengl-themepainter --disable-vaapi

It runs using OpenMax on both RPI 3 and 4.

"Openmax Normal" works for me but not "Openmax High Quality". Also when openmax render is selected, I cannot select opengl osd, only softblend osd is available.

Do you see something different?
