IMX8QM HARDWARE H264

HAKANAYDN — Mon, 21 Oct 2024 12:01:41 GMT

Hi,

In the "i.MX 8 GStreamer User Guide" PDF, it is stated that the hardware H.264 capabilities vpuenc_h264 and vpudec can be implemented. However, these features are not present in the GStreamer library. How should I configure the Yocto project to enable these hardware features? Currently, we are using the v4l2h265dec and v4l2h265enc codecs, but we are experiencing issues with high-resolution video using these plugins. How can I add the vpuenc_h264 and vpudec GStreamer plugins to the Yocto project for the i.MX 8QM?

Hello,

Which resolution do you want to decode? since Mx8QM support 4K @30 fps and videos work well in this resolution with gstreamer.

Hi,

Are vpudec and vpuenc_h264 plugin for gstreamer available in imx8qm SOC ? We are not seeing the vpudec and vpuenc_h264 listed using gst-inspect. But we see v4l2h264dec, v4l2h264enc. Which ones do I use for h264 encoding and decoding ? Which one is supported by hardware ?
