Hi Hans, I upstream v4 on 8/10, I don't know why this version is not shown in https://patchwork.kernel.org. But I could see it in other link. http://www.spinics.net/lists/arm-kernel/msg523095.html I refine DocBook and vb2 queue_setup function in v4. For the MT21 format, if I put MT21 into separate patch, this patch series will build fail, I was confused how to fix this issue? For VP9, I will merge this three patchs to V4L2 Decoder patch series. * linux-media: [v1,1/3] videodev2.h: add V4L2_PIX_FMT_VP9 format. - http://patchwork.linuxtv.org/patch/34392/ * linux-media: [v1,3/3] V4L: add VP9 format documentation - http://patchwork.linuxtv.org/patch/34393/ * linux-media: [v1,2/3] v4l2-ioctl: add VP9 format description. - http://patchwork.linuxtv.org/patch/34394/ best regards, Tiffany On Mon, 2016-08-15 at 10:30 +0200, Hans Verkuil wrote: > Hi Tiffany, > > This needs a v4: the DocBook format has been replaced by sphinx, and I also see that > the vb2 queue_setup function is out-of-date (the allocation contexts no longer exist). > > There were also a lot of comments about the MT21 format.
