| 03:08 | <robman> | afternoon all 8) does anyone know if you can get an ImageData directly from an HTMLVideoElement in some way? or is the only solution to do a 2dcontext.drawImage(video) -> 2dcontext.getImageData(...) pipeline? |
| 03:09 | <annevk> | it's the only way |
| 03:09 | <robman> | boo |
| 03:09 | <robman> | very innefficient |
| 03:09 | <robman> | thanks annevk |
| 04:26 | <jwalden> | robman: not necessarily inefficient; I could imagine the former call living entirely in GPU memory in the right circumstances, and with good enough implementations |
| 04:26 | <jwalden> | whether any of that is the case, I couldn't say, tho |
| 04:28 | <zewt> | jwalden: vanishingly unlikely |
| 04:28 | <jwalden> | yeah, we're probably not there yet |
| 04:28 | <zewt> | well, no--unlikely for both calls |
| 04:29 | <zewt> | the first call, perhaps eventually |
| 04:30 | <jwalden> | sure, the second basically never will, don't disagree there |
| 04:30 | <jwalden> | never said anything about the second :-) |
| 04:31 | <zewt> | of course, having the first be on the GPU would mean the second call would be even slower :) |
| 04:32 | <zewt> | (if it has to make a GPU to RAM transfer, instead of RAM to RAM, or even better a copy-on-write of the original) |
| 09:37 | <annevk> | Ms2ger, congrats on getting all those patches landed |
| 09:37 | <annevk> | guess isWhiteSpace should be LATER/WONTFIX |
| 09:37 | <Ms2ger> | Mm |
| 10:13 | <robman> | zewt / jwalden - wondered what your thoughts on drawImage(video)/getImageData(...) on a hidden canvas context were - does that add any performance improvements or is it effectively just the same |
| 10:16 | <robman> | or if anyone else has a view on that too 8) |
| 14:46 | <sanxiyn> | Hi! |
| 14:46 | <sanxiyn> | This may be of your interest: https://github.com/sanxiyn/csstty |
| 14:46 | <sanxiyn> | Started today. |
| 15:02 | <sanxiyn> | Hi |
| 15:44 | <zewt> | robman: don't have to even put the canvas in a document |
| 21:23 | <zewt> | must resist the urge to reply "what about triggering standards mode?" |
| 23:57 | <robman> | zewt - thanks for the tip about the DOM-less canvas - will that save much overhead? |
| 23:57 | <zewt> | compared to it being hidden? probably not (but you'd have to try it) |
