Hantro VC8000E Video Encoder Support on Toradex Platforms
Based on the available Toradex documentation, I can provide some context about video encoding capabilities, though specific information about the Hantro VC8000E encoder on mainline kernels is not explicitly covered in the current sources.
Current Video Encoding Support
The Toradex documentation shows that video encoding is supported through GStreamer pipelines using hardware acceleration elements(1). For encoding, the recommended approach uses elements like vpuenc_h264 for H.264 encoding with VPU acceleration(1).
Here’s an example encoding pipeline from the documentation:
# gst-launch-1.0 videotestsrc num-buffers=300 ! video/x-raw, width=1920, height=1080, framerate=60/1 ! videoconvert ! vpuenc_h264 ! video/x-h264 ! h264parse ! qtmux ! filesink location=videotestsrc.mp4

VPU Support Challenges
The community discussions reveal some important limitations regarding VPU support on Toradex platforms. For instance, there are known performance issues with VPU acceleration on certain modules like the iMX8DX with Torizon OS 6, where users experience high CPU usage and poor performance when hardware acceleration isn’t properly utilized(2).
Additionally, there’s an important note from Toradex support indicating that “at the current moment there is no official VPU support for any SOM on Torizon OS 7.X”(2), though they do plan to implement this feature.
Recommendations for Your Use Case
Given your specific requirements for:
- High-resolution video recording from Sony sensors
- Mainline kernel (6.17) with libcamera
- Efficient encoding capabilities
The current Toradex documentation suggests using GStreamer with available hardware acceleration elements. You can also try the encodebin element for automatic pipeline creation:
# gst-launch-1.0 videotestsrc num-buffers=300 ! video/x-raw, width=1920, height=1080, framerate=60/1 ! encodebin ! filesink location=videotestsrc.mp4

Next Steps
For specific information about Hantro VC8000E encoder support on mainline kernels 6.12+ and compatibility with your libcamera setup, I’d recommend checking the current Toradex BSP documentation and kernel configuration for your specific hardware platform, as this level of detail about future kernel support and specific encoder hardware isn’t covered in the available sources.
The GStreamer framework provides a flexible foundation for multimedia processing that can adapt to different hardware acceleration capabilities as they become available(1).
