Intel sold an unlocked H264 hardware decoder to me that is usable via the VAAPI interface. Where can I find the H264 patent license confirmation?

[Darkspirit]

• One can buy a license key to unlock Raspberry Pi's MPEG2 hardware decoder: https://codecs.raspberrypi.org/mpeg-2-license-key/ (H264 hardware decoder is already unlocked/licensed by default, it could be used via ffmpeg h264_v4l2m2m api)
• One can buy a license to unlock Windows' HEVC software decoder+encoder: https://www.microsoft.com/en-us/p/hevc-video-extensions/9nmzlz57r3t7
• Cisco pays a capped license fee for letting every interested consumer use its openh264 software decoder.
• Canonical pays a license fee to be able to sell its Ubuntu OS with a h264 software decoder included.
• Intel sells its APUs with an unlocked H264 hardware decoder, it does not require consumers to buy a license key to unlock it, therefore Intel (or a third party chip vendor of Intel's H264 hardware decoder) must have paid MPEG-LA patent license fees to sell an unlocked H264 hardware decoder to me as customer. Where can I find the patent license confirmation that Intel (or a third party chip vendor of Intel's H264 hardware decoder) has paid the fee that allowed Intel to sell an unlocked H264 hardware decoder to an APU customer like me? (VAAPI is an API, not a decoder, one can use it to transfer H.264 bytes to the unlocked/licensed hardware decoder (Intel Quick Sync Video?) and to receive images back.)

I ask this question for https://bugzilla.mozilla.org/show_bug.cgi?id=1737116.

sorry for late response, but we are engineering team, suppose you need to contact Intel legal about it.
