Hi Suresh,
If I miss something here please provide some more details on the question.
Emils question is if the "surfaceless" platform is identical to the
"drm" platform why not use the drm platform in the first place?
And yeah, that is a rather good question.
Regards,
Christian.

HI,
- why do we need "surfaceless" support
ChromeOS supports surfacelsess and we need this va enablement for
surfaceless in chromium.
- does upstream VAAPI has surfaceless platform
Yes. It uses headless support of VA-API for decoding.
- why is the surfaceless implementation identical to the DRM one
If I understand your question correctly, In case of surfaceless platform
,it uses headless support of VAAPI, which will use drm implementation. If I
miss something here please provide some more details on the question.
Thanks,
Suresh G

Repeating some earlier questions:
- why do we need "surfaceless" support
- does upstream VAAPI has surfaceless platform
- why is the surfaceless implementation identical to the DRM one
Without any additional information, I think you should be using the drm
platform.
Thanks
