Bug 22432 - Allow SourceBuffer.appendBuffer to take ownership of the ArrayBuffer <acolwell> [18]https://www.w3.org/Bugs/Public/show_bug.cgi?id=22432 [18] https://www.w3.org/Bugs/Public/show_bug.cgi?id=22432 acolwell: this one we discussed in the past ... i thought our resolution was to do nothing but we didn't close the bug adrianba_: we don't plan to update our implementation currently ... the two choices we have are to change the spec (and risk it changing again) and maybe get stuck in CR because noone implements this ... or we could leave it undefined in this version of MSE and come back to it in future cyril: a clarification - i can't find a definition for neutered concept acolwell: i have only seen it in this comment - in Chromium we only use this in WebAudio and there is no way to unneuter buffers ... so i don't think it is formally defined yet cyril: the Typed Array spec says that the buffer is size 0 while neutered acolwell: basically the idea is to hide the content so you can't modify it during the append ... it doesn't seem like it is quite well defined - maybe it is in the Khronos spec - we should look ... since we allow ArrayBufferView to be appended does it neuter the parent buffer too? ... i can respond to this bug and outline some of the things we've discussed here and see what they say ... any other questions? Bug 23169 - reconsider the jitter video quality metrics again <acolwell> [19]https://www.w3.org/Bugs/Public/show_bug.cgi?id=23169 [19] https://www.w3.org/Bugs/Public/show_bug.cgi?id=23169 acolwell: this one was filed by dsinger to open the discussion again about the jitter metric ... mark and i also replied ... i was waiting for mark or dsinger to comment on my reply ... i need feedback to know if there is an action for me to take <markw> I haven't reviewed your response yet <markw> I wil do it now ;-) Bug 23272 - [MSE] Extra ; at the end of the totalFrameDelay declaration acolwell: this is done Any other business acolwell: anything else people would like to talk about ... next week is EME ... talk in two weeks Adjournment acolwell: adjourned Summary of Action Items [NEW] ACTION: acolwell to file bug about media format registry [recorded in [20]http://www.w3.org/2013/09/24-html-media-minutes.html#action 01] [End of minutes] -----Original Message----- From: Paul Cotton [mailto:Paul.Cotton@microsoft.com] Sent: Saturday, September 21, 2013 8:12 PM To: public-html-media@w3.org Subject: {agenda} HTML WG media telecon 2013-09-24 - MSE status and Last Call bug discussion The HTML WG media teleconference meeting will occur on 2013-09-24 for up to 60 minutes from 15:00Z to 16:00Z. http://timeanddate.com/s/2g02 Tokyo midnight, Amsterdam/Oslo 17:00, London/Dublin 16:00, New Jersey/York 11:00, Kansas City 10:00, Seattle/San Francisco 08:00.
