maximum supported video resolution for media SDK and h264_qsv

Hi there,

I  am using h264_qsv with ffmpeg to encode video @ 3840 x 2160 without an issue. 

 However, the h264_qsv codec initialization fails when I set a video resolution of 7680 x 1080.    Does anyone know if this is a limitation of  h264_qsv codec? 

How about  Intel Media SDK,  does it support encoding H264 @ 7680 x 1080 ? 

thank you and regards

Leon

Hi Leon,

No, if you see the latest release notes from Open Source Media SDK, the maximum resolution for H.264 decoder is 4096x2304:

Normally I check the following places for Media SDK specs:

Open Source Media SDK: https://github.com/intel-media-sdk/mediasdk and go to the release tab for all the release info, if the release notes is not posted in the page, it must be in the package.

From the Open Source Media SDK landing page, you can go to Intel® media driver page for codec details:

Hi Mark

thank you for your reply. 

Do you mean that https://github.com/intel/media-driver  is the source code repo for h264_qsv codec inside ffmpeg?  If not, is h264_qsv open source and where can I find the source code? To your knowledge, is h264_qsv for ffmpeg still actively maintained by Intel and/or the open source community? thank you.

regards

Leon
