Qualcomm IM SDK GStreamer Plugins

The QIM SDK encapsulates hardware complexity within a modular plugin architecture, freeing developers from the burden of managing low-level platform libraries or hardware-specific details that vary across Qualcomm chipsets and generations.

Each QIMSDK plugins in the SDK maps directly to a dedicated hardware accelerator — including video encode/decode, camera ISP, GPU, display, and AI/ML accelerators — giving developers a clean, unified API surface to build sophisticated multimedia and AI pipelines with minimal integration overhead.

Compilation Instructions

Download and install the toolchain

Follow the steps below to obtain the cross-compilation toolchain required to build this project.

1. Get the latest Nightly Build (wrynose) from the below link:

   https://github.com/qualcomm-linux/meta-qcom/actions/workflows/nightly-build.yml

2. Locate the "build-nightly / publish_summary summary" section within the workflow results.

3. Expand the "Download URLs Details" section to reveal the available build artifacts.

4. Under the qcom-distro-sdk distribution for the qcom-armv8a target, click on the "Files" link.

5. In the file list, use the "Type" filter to select .sh files, then download the following toolchain installer:

   qcom-distro-x86_64-qcom-multimedia-proprietary-image-armv8a-qcom-armv8a-toolchain-2.0.sh
   

6. Extract and install the toolchain.

   bash qcom-distro-x86_64-qcom-multimedia-proprietary-image-armv8a-qcom-armv8a-toolchain-2.0.sh -d <path_to_install_toolchain> -y
   

7. Source the cross-compilation toolchain environment.

   source <path_to_install_toolchain>/environment-setup-armv8a-qcom-linux
   

   Note: This environment must be sourced for every new shell session before building the project.
