10. Hardware video codec support:

The C3V platform has hardware video codecs and provides a V4L2 interface. It currently supports GStreamer 1.20.1, 1.22.9, and 1.24.2:

For Ubuntu 20.04 and Ubuntu 22.04, we recommend using version 1.22.9, which is the same as the version that Buildroot 24 used default. It’s newer than the default versions of Ubuntu 20.04 and Ubuntu 22.04. And its patch can be found in the code path: <C3V_code>/linux/rootfs/initramfs/buildroot/package/gstreamer1.

For Ubuntu 24.04, we recommend using version 1.24.2, which is the same as the version of Ubuntu 24.04 used default.

To use version 1.20.1, please use the following patch:

This patch is older than other GStreamer patches and may have some bugs, if you really need to use this version, please contact us to update it.
