Where can I get the recent ones ?
Could you push it to your public repo ?
I've updated the tmp/imx-ipu-scaler branch.
Thx. already integrated it into my tree - works fine :)
By the way: i still have some your older patches (2012) in my tree,
eg. some mediabus, camara, display timing stuff, etc ... not sure
whether I really need them for my device.
Should I post them to linux-media list for review ?
Oh, and I also still have your famous DRM_IOCTL_MODE_MAP_DUMB hack
(the "Reluctantly-signed-off-by:" one ;-), meanwhile rebased / adapted
into 4.x. Do you have any idea, what the amd-gpu driver/library exactly
does with the retrieved address ? Send it directly to the gpu ?
That should be capture-io-mode=dmabuf for the decoder and
output-io-mode=dmabuf-import for the converter element. h264parse
doesn't provide and fbdevsink can't handle dmabufs, so the decoder's
output-io-mode and the converter's capture-io-mode should be kept as
mmio.
I played around a little bit - this command line only takes 55% cpu:
gst-launch-1.0 filesrc location=montage.mp4 \!
qtdemux \! h264parse \! v4l2video4dec output-io-mode=4 capture-io-mode=4
\! v4l2
video0convert capture-io-mode=4 output-io-mode=5 \! fbdevsink
By the way: what's the exact difference between dmabuf and
dmabuf-import ?

Well, you perhaps can imagine - I dont trust these guys ...
