Why do more work on mpeg-2?

Couldn’t that path just be left without acceleration, being it’s a less complex codec to begin with, usage is not growing, and the data sources are likely smaller to begin with (no 4k for example)?

It's still useful for some applications. ATSC digital broadcasts in the U.S., for example, are in MPEG-2, as are the signals provided by many cable companies. I have an HDHomeRun Prime, and purchased the MPEG-2 HW Decoder license[1] for my Raspberry Pi 3 to make things a bit smoother.

Isn't the Raspberry Pi 3 powerful enough to do MPEG-2 decoding in software?
Not if you want it to do anything else at the same time, and not if you need de-interlacing of the 1080i streams that half the over-the-air channels use.
Since they want to do hardware x264, are there any patent issues they'll have to deal with, or will that be included in the cost? I didn't see anything listed on the Kickstarter page.
Looks like Bootlin is located in France. France doesn't recognize software patents (as I understand it), which is why VLC can exist.

(Though I noticed on VLC's website that the EC could try to change that: https://www.videolan.org/press/patents.html)

DVDs, too, are almost all MPEG-2.
