The RK3566 and RK3568 SoCs come with a small Hantro instance which
is solely dedicated to encoding JPEG. This patch adds the necessary
structs to the Hantro driver to allow it to function.
Tested with the following GStreamer command:
gst-launch-1.0 videotestsrc ! v4l2jpegenc ! matroskamux ! \
filesink location=foo.mkv
I just tried this pipeline on v5.19. The filesize generated is increasing and data is generated. However the content seems to be unusable. When playing foo.mkv with e.g. vlc the following errors, that no JPEG data was found in the images, is generated: [mjpeg @ 0x7f2f08c1f780] No JPEG data found in image [mjpeg @ 0x7f2f08c1f780] No JPEG data found in image [mjpeg @ 0x7f2f08c1f780] No JPEG data found in image ... The same with gstreamer: gst-launch-1.0 filesrc location=foo.mkv ! decodebin ! glimagesink ../ext/jpeg/gstjpegdec.c(1418): gst_jpeg_dec_handle_frame (): /GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstJpegDec:jpegdec0: Decode error #53: Not a JPEG file: starts with 0x00 0x00 .. Do you have an idea why that is? Did you test the pipeline with an earlier kernelversion and validated the generated content of foo.mkv?
