Has anyone here worked on s5p-mfc drivers?
https://ess.cs.tu-dortmund.de/lockdoc-elixir/linux-lockdoc/lockdebug-v4.10-0.10/source/drivers/media/platform/s5p-mfc/s5p_mfc_enc.c#L668
I'm trying to figure out why the maximum for the V4L2_CID_MPEG_VIDEO_VPX_I_FRAME_QP  fields is 127
but the VPX range for QP is usually [0, 63]
is this a bug?
taliho: it looks like a bug, on 6 bits a re program per min/mx, this is the max as an example (in case I read it wrong) reg &= ~(0x3F << 8);  reg |= (p_264->rc_max_qp << 8);
* only 6 bits
thanks ndufresne , I'll try to send a patch to the ml
is this the right ml: linux-media@vger.kernel.org  ?
taliho: yes
but in general, use get_maintainer.pl
ok, sounds good

thanks
hverkuil: qv4l2, on wayland, it renders in ARGB and the alpha is 0, which makes it unusable
it use to go through XWayland
in general, just setting alpha to 1 in your shader resolves this type of issue
