# 15:48 [tantek] it's not because none of that is very helpful in practice. better to HEAD request the video to get its content-type. any content-type in markup is advisory at best # 16:01 aaronpk See also: browsers rendering a jpg fine even if the filename and web server header is .png # 16:02 aaronpk What microformats *can* be helpful for is if a particular kind of media requires different html markup to render # 16:14 sknebel afaik browser do use these tags for source selection, so if information is provided passing it through is likely useful rattroupe[d], kimberlyhirsh[d], jacky and angelo joined the channel
# 17:40 [tantek] sknebel, yes it's likely implemented somewhere, but in general it's a bad approach as with all metadata separate (and duplicated) from the data, it tends to rot # 17:41 [tantek] aaronpk is correct, even if *served* as one content-type on HTTP, browsers sniff the bytes to actually figure out what kind of image etc. it is # 17:41 [tantek] so basically, this avenue of technology development is not worth investing in, propagating # 17:41 [tantek] it's only in HTML for legacy reasons and it's too much work for too little reward to remove. zack[m]1, barnaby and Darius_Dunlap[d] joined the channel

# 18:37 aaronpk i do think sknebel is right that the browser does use the html attributes for video source stuff for handling multiple quality of the same video and such jacky joined the channel

# 19:11 aaronpk that page could benefit from some more detail about how the browser uses these hints # 19:23 [tantek] and frankly, examples of sites that actually depend on it (I don't know of any) ur5us, angelo, barnaby, barryf[d], Jack[d], jacky, mossymaker[d], dovedozen[d], Christian_Olivie, Darius_Dunlap[d], kimberlyhirsh[d], indieweb-irc-bri, Nan[d], rattroupe[d], daiyi[d], hoenir, trig[d], YimingWu[d], capjamesg[d], Asaf_Agranat[d], Silicon[d], wackycity[d], marksuth[d], Jeremiah[d], corenominal[d], shaunix[d] and toby3d[d] joined the channel
