Jan 20, 2015 at 19:23 comment added Peter Cordes Yeah I googled a bit after posting that comment. Unfortunately it seems there are a fair amount of HW decoders that support Main but not High, so a year or two of phones. I guess it makes sense that 8x8dct might require different logic blocks on a FPGA or ASIC, unlike the case for software where it's not hard. (CPU power to decode CABAC is the hard part for going from baseline to main, for software I think.) Anyway, blargh, are we never going to get rid of sub-optimally encoded videos, thanks to crappy devices? As soon as we do, devices with partial h.265 support will come out... square 1
Jan 20, 2015 at 9:08 comment added Duvrai The Main profile recommendation comes from the mobile device world. For example most Apple A4 and A5 processors are H.264 Main profile limited. More specifically iPod Touch 4G & 5G, iPod 1 & 2, iPhone 4, AppleTV 2G & 3G (model A1427). Anything beyond is High profile.
Jan 20, 2015 at 6:11 comment added Peter Cordes Why would you ever use Main, not High, profile, for anything? I thought HW decoders were usually either baseline or high, so worse compression (no 8x8dct) for no or very small gain in combatibility.
