libGL error: unable to load driver: rockchip_dri.so #339

Open AndroidDesigner opened 11 months ago

AndroidDesigner commented 11 months ago

Hello I wanna stream an IP camera by the rtsp protocol. So I have used media_kit package to play a media. It works fine on my Ubuntu 16.04 x86_64 system, but results in the below error in a Debian 10 buster aarch64 system. The mvp and vlc from cmd (for example vlc rtsp://ip:554/live/0/MAIN) works in both systems.

code:

import 'package:media_kit/media_kit.dart';
Player player = Player();
await player.open(Media('rtsp://ip:554/live/0/MAIN'));
player.play();

error:

libGL error: unable to load driver: rockchip_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: rockchip
libGL error: unable to load driver: rockchip_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: rockchip
Segmentation fault

How can I solve the problem?

What board are you using? Are you using some debian derivative (armbian, dietpi) or vanilla debian buster? Have you done any special setup for opengl (installed some driver packages, etc)?

Can you try running kmscube and see if it works?

In general it seems like the GL driver is not installed, or not installed correctly. Maybe there's some documentation about that for your distro, it could vary from board to board.

Btw, media_kit will not work with flutter-pi, at least not if you're using video playback. If a package on pub.dev says it supports linux, in 99% it actually means it supports the official linux desktop embedder, not third-party embedders such as flutter-pi, ivi-homescreen or the sony-embedder.

For video playback using flutter-pi I'd recommend using the gstreamer video player: https://github.com/ardera/flutter-pi#gstreamer-video-player and the feature/compositor-ng branch

I'm playing audio fine (with the media_kit package) now wanna stream an IP camera too.

Yes, it is working fine (A colorful cube is rotating in center of screen with a white background).

I'm using the compositor-ng branch and also cloned the source code of the flutter-pi-gstreamer-video-player, but it results in the below error:

ah, so at least it's starting up on feature/compositor-ng now? It didn't previously, right? can you build with -DCMAKE_BUILD_TYPE=Debug if you haven't already, run again, and attach the whole flutter-pi output? (not just the error)

No. I'm using feature/compositor-ng in both cases.

Do you mean run flutter-pi with the -DCMAKE_BUILD_TYPE=Debug? I'm building the asset bundle with flutter build bundle and am using debug mode (not release mode).

run the app in debug mode:

sudo flutter-pi /path/flutter_assets/ -DCMAKE_BUILD_TYPE=Debug

No, I mean configuring the build with -DCMAKE_BUILD_TYPE=Debug, i.e. cmake -DCMAKE_BUILD_TYPE=Debug .... Then build again (using make or ninja) and run flutter-pi. That'll output more debugging information

Are you on the latest commit of the feature/compositor-ng branch? Looks like this is a bug I fixed some weeks ago

AndroidDesigner commented 11 months ago

Yes I'm using the latest version of feature/compositor-ng branch. What is the problem?

ardera commented 11 months ago

The problem I fixed was a typo in the check for EGL_EXT_image_dma_buf_import support: https://github.com/ardera/flutter-pi/commit/7325374b1c64801739804ea50f4f7496edeb63ff

Other than that I'm not sure what could cause this.

AndroidDesigner commented 11 months ago

As you can see, the log says:

/path/flutter-pi/src/plugins/gstreamer_video_player/frame.c: EGL does not support EGL_EXT_image_dma_buf_import extension. Video frames cannot be uploaded.

what that means?

ardera commented 11 months ago

That means it could not find EGL_EXT_image_dma_buf_import in the list of supported EGL extensions reported by the driver.

But, as you can see, that's clearly not correct, it is actually listed as supported:

...
  display extensions: ... EGL_KHR_no_config_context EGL_EXT_image_dma_buf_import EGL_EXT_image_dma_buf_import_modifiers ... 
...

So something must be wrong with the check, which was the case like 3 weeks ago. Hence my suspicion you're on an outdated revision
