[flutter-pi] Could not find a suitable DRM encoder. #96

Closed mateusz-grzegorzek closed 3 years ago

mateusz-grzegorzek commented 3 years ago

Hello, First of all, thanks a lot for your job! I would be very grateful if you could help me with the DRM encoder problem when running flutter_gallery.

I've done all the steps regarding installation flutter-pi, but when I try to run flutter_galary on my Raspberry Pi 4, flutter-pi throws below error:

pi@raspberrypi:~/Projects/flutter_gallery/build/flutter_assets $ /home/pi/flutter-pi/out/flutter-pi . [flutter-pi] WARNING: display didn't provide valid physical dimensions. The device-pixel ratio will default to 1.0, which may not be the fitting device-pixel ratio for your display. [flutter-pi] Could not find a suitable DRM encoder.

ardera commented 3 years ago

I just pushed some stuff to the develop branch that should fix this. Can you try that out and see if it fixes it?

    * Add reverse property to PageTransitionSwitcher that dictates whether the new widget transitions under or over the old child

    * Remove duration that was used in testing

    * update code segments

Still error :(

I think you messed something up here. flutter-pi has no commit 9b11f127fb46cb08e70b2a7cdfe8eaa8de977d5f, but flutter_gallery has. Maybe you cd'd into the flutter_gallery directory first and then ran git log? (Also, I'm pretty sure the output of git status is outdated if you didn't run git pull or git fetch before.)

Just to be on the safe side, could you please delete the whole flutter-pi folder and then check it out again using git clone -b develop https://github.com/ardera/flutter-pi.git? (Just to be sure we're not actually debugging git problems)

Also, can you send me the complete output of the raspinfo command? (Install using sudo apt install raspinfo)

mateusz-grzegorzek commented 3 years ago

Here is output from raspinfo: raspinfo.txt

Regarding git log - sorry for that, it was my mistake. Here is proper output:

Okay, thanks

Can you try two more things?

I've run those commands and here is the output:

Sorry, I thought I replied to this thread already.

I couldn't reproduce the problem in my testing, even when I used a HDMI monitor and changed my /boot/cmdline.txt to match yours exactly.

kmscube with /dev/dri/card0 works:

Yeah, it's always one of the cards in /dev/dri that works. For me /dev/dri/card1 is the working one. Though this shouldn't really matter as flutter-pi ignores non-working cards and tries to find the first working one.

Can you try this for me?

  1. $ sudo bash
  2. # echo 0x1ff > /sys/module/drm/parameters/debug
  3. # exit
  4. run flutter-pi (you can also try running it as root)
  5. $ sudo bash
  6. # echo 0x0 > /sys/module/drm/parameters/debug
  7. # exit
  8. send me the complete contents of /var/log/syslog
mateusz-grzegorzek commented 3 years ago

syslog: syslog command line output: cmdline

I don't know why but the DRM bug is gone (replaced by Dart Error: Can't load Kernel binary) Could it be related to the execution of this command: sudo /usr/bin/kmscube -D /dev/dri/card0 ?

ardera commented 3 years ago

replaced by Dart Error: Can't load Kernel binary

Make sure your engine binaries and flutter SDK are up to date.

Could it be related to the execution of this command: sudo /usr/bin/kmscube -D /dev/dri/card0

No, that's not possible. Did you reboot between the sudo apt upgrade and the invocation of flutter-pi though? The changes to kernel & firmware only take effect after reboot.

mateusz-grzegorzek commented 3 years ago

DRM bug related to this issue is fixed probably by executing commands sudo apt update && sudo apt upgrade and rebooting RPi, so I created a new issue related to Invalid SDK hash: Invalid SDK hash
