Hello,
yesterday I enabled the Hantro JPEG encoder on my RK3566[1], and noticed
a peculiar thing: when encoding a 1920x1080 video[2] with gstreamer
through the hardware JPEG encoder using v4l2jpegenc, it'd result in a
1920x1088 output with a green bar at the bottom[3].
I asked on the #linux-media IRC channel on OFTC about this, and was told
by Nicolas Dufresne (hello, fellow Nicolas!) that I should post to this
list to make sure this doesn't fall through the cracks.
The kernel used was based on 5.18-rc4, and the GStreamer version is
1.20.1.
The GStreamer command used was:
gst-launch-1.0 filesrc location=panduroll.mp4 ! \
qtdemux name=demux demux.video_0 ! decodebin ! \
videoconvert ! v4l2jpegenc ! matroskamux ! \
filesink location=pandu_but_mjpeg.mkv
Regards,
Nicolas Frattaroli
