Subject: Re: [PATCH v3 0/9] Add MT8173 Video Decoder Driver
Date: Mon, 15 Aug 2016 17:03:41 +0800 [thread overview]
Message-ID: <1471251821.28498.7.camel@mtksdaap41> (raw)
In-Reply-To: <bdac7fe1-6425-2a3d-777f-86cfd1ee26e0@xs4all.nl>
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

Hi Hans,

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.

* linux-media: [v1,2/3] v4l2-ioctl: add VP9 format description.
- http://patchwork.linuxtv.org/patch/34394/

Subject: [PATCH v3 0/9] Add MT8173 Video Decoder Driver
Date: Mon, 15 Aug 2016 17:03:41 +0800 [thread overview]
Message-ID: <1471251821.28498.7.camel@mtksdaap41> (raw)
In-Reply-To: <bdac7fe1-6425-2a3d-777f-86cfd1ee26e0@xs4all.nl>
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
