It has been tested on an stm32mp25 and there exists a gstreamer user: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5676 example pipeline: gst-launch-1.0 videotestsrc num-buffers=30 ! video/x-raw, format=YUY2 ! v4l2slh264enc ! filesink location=test.h264 Rebased onto v6.6 with: - some patches from ST to actually run the hardware - my previous VP8 statless encoding series - VP8 support for H1 from Hugues Fruchet In particular, this series depends on the latter, which can be found here: https://patchwork.linuxtv.org/project/linux-media/list/?series=11358 Here's a branch which contains everything needed to actually run: https://gitlab.collabora.com/linux/for-upstream/-/tree/h264-enc-rfc-6.6 I kindly ask for comments.
