Unable to use decodebin on Quest2

mvvvv · August 14, 2024, 4:13pm

Hello. I’m trying to use the Quest Hardware decoders on the Meta Quest2.

First, gstreamer works well with software decoders. The problem is when I try to use the hardware decoders (androidmedia is loaded)

When trying to read a local file:

mvvvv/StereoKit-rust-gstreamer/blob/b9d53c9262d42878df6f0c2c3a43b240c45bb833/src/video1.rs#L298


      
              let video_tex = Tex::find(&tex_id)?;
              Video1::set_video_callback(appsink, video_tex, self.width as usize, self.height as usize);
          
              self.bus = Some(pipeline.bus().expect("Pipeline without bus. Shouldn't happen!"));
              self.pipeline = Some(pipeline);
              Ok(())
          }
          
          /// init a video
          ///
          fn init_decodebin(&mut self, uri: String, v3_enabled: bool) -> Result<(), anyhow::Error> {
              let (tex_id, pipeline) = self.init_player()?;
          
              let decode = if uri.starts_with("file:") || uri.starts_with("https://") {
                  let uridecodebin = if v3_enabled {
                      ElementFactory::make("uridecodebin3").property("uri", uri).build()?
                  } else {
                      ElementFactory::make("uridecodebin").property("uri", uri).build()?
                  };
                  pipeline.add_many([&uridecodebin])?;
                  uridecodebin

I’m having following errors:
