Adding a New Plugin to an Existing Meta Layer

Technical Support

In my Yocto system, gst-plugins-rs is not available, so I am unable to build the audiofx plugin and the following elements: audioloudnorm, audiornnoise, ebur128level, hrtfrender, and rsaudioecho. and my Streamer version is 1.20.3.

Adding a New Plugin to an Existing Meta Layer

Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

Based on your setup (Colibri iMX7D 1GB running BSP 6.8.5-devel with GStreamer 1.20.3), you’re working with a Yocto-based system that doesn’t include gst-plugins-rs by default(1).

To add the audiofx plugin and its elements to your existing meta layer, you’ll need to:

Steps to Add gst-plugins-rs

  1. Create a recipe in your custom meta layer for gst-plugins-rs. Since this is a Rust-based GStreamer plugin collection, you’ll need to ensure your Yocto build environment supports Rust compilation.

  2. Add the recipe to your meta layer under recipes-multimedia/gstreamer/ directory structure.

  3. Include the recipe in your image by adding it to your image recipe or local.conf.

Important Considerations

For your Colibri iMX7D platform running GStreamer 1.20.3(1), you’ll need to:

  • Verify Rust toolchain support in your BSP version
  • Ensure compatibility between gst-plugins-rs version and your GStreamer 1.20.3
  • Consider build time and storage requirements, as Rust compilation can be resource-intensive

Alternative Approach

If you’re looking to add audio processing capabilities without building from source, you might want to explore:

  • Using available GStreamer plugins from gst-plugins-good or gst-plugins-bad that provide similar functionality
  • Checking if your required audio elements have equivalents in the already-available plugin packages

For detailed guidance on creating custom Yocto recipes and layers for your specific BSP version, you may find relevant discussions on the Toradex Community by searching for “custom meta layer recipes.”

To better understand your use case, could you please provide the following information?

  1. Are you using the Toradex Reference Multimedia Image, or have you created a custom Yocto image?

  2. Which Yocto release/branch are you building (Kirkstone, Scarthgap, etc.)?

  3. What is the exact application or use case that requires these specific GStreamer elements?

Also, could you check whether a gst-plugins-rs recipe already exists in your build environment?

find layers -name "gst-plugins-rs*.bb*"

or

bitbake-layers show-recipes | grep gst-plugins-rs

If no recipe is present, it means your current BSP does not include gst-plugins-rs, and you would need to import the appropriate recipe
