Hi,
I'm currently working with DG2 (A380) graphics card.
Looks like it can't encode interlaced video to h.264 (AVC) format.
Is it really true by GPU design or I have a bug in drivers/VPL?
PS:
If interlaced signals support is removed from new video cards, then I think it is a good idea to reflect it in the feature specifications here:

Hi, Thanks for your patience.
We regret to inform you that, currently there is no support to Encode Interlaced video to h.264(AVC) on DG2 and this might be planned to feature in the long term. Could you please let us know if you need any further information on this.

Hi, Thanks for posting in Intel Communities.
In order to debug your issue further, can you provide the below details.
1. Processor Information:
2. OS Details:
3. oneVPL Version:
4. oneVPL GPU Runtime version:
5. Your sample interlaced video as a zip file if possible.
Thanks and Regards,
Rajashekar

I checked it in two environments:
1. Processor: i7-11700 and i7-6700
2. OS: Windows 10 Pro 22H2 and Windows 10 IoT Enterprise LTSC 21H2
3. oneVPL Version: 2.8
4. oneVPL GPU Runtime version: 2.8, driver 31.0.101.4255
5. sample interlaced video: since the input data is an uncompressed video, then you can take any arbitrary content, even a random set of bytes, it does not matter
To reprocude, you can use sample_encode from oneVPL SDK.
sample_encode.exe h264 -AdapterNum 1 -hw -d3d11 -w 1920 -h 1080 -f 25 -tff -b 3000 -timeout 20 -i input.raw -o NUL:
where -AdapterNum parameter should correspond to DG2 card
Without -tff parameter (which means progressive), the application works.
With -tff parameter (which means interlaced), the application is unable to initiate encoding engine.

Hi Rajashekar,
Can you tell if the lack of interlacing will be in all modern/future dGPU/iGPU or only in some models?
