[Video Player] Plugin compatibility with flutter-auto embedder

[mmerah]

Hello.

I have an iMX8M Mini. I tried the example/demo application as is. However, I seem to have 2 issues:

1. An error happen when pressing play [ERROR:/usr/src/debug/flutter-auto-runtimerelease/git-r0/git/shell/static_plugins/gstreamer_egl/gstreamer_egl.cc(1552)] Unable to retrieve current position.
2. The metadata appears but nothing happens. If I use the following pipeline I can stream videos with gstreamer though: $ gst-launch-1.0 filesrc location=/path/to/video.mp4 ! qtdemux ! queue ! h264parse ! v4l2h264dec ! imxvideoconvert_g2d ! queue ! autovideosink.

Here is a log of what happens:

I'm sorry, but I'm not sure what flutter-auto is. Basically, GStreamer plugins that are accelerated and supported by H/W depend on SoC/BSPs.

You are correct. This is a problem with the gstreamer pipeline itself on my target hardware (pipeline with playbin do not work while others do. This is a package/configuration problem)
