15:41:43 <franck> Req 6: "must work with open source browsers"
15:42:06 <franck> CS: make sure that open source browser can use this method to do ABR
15:42:08 <Zakim> + +1.908.848.aadd
15:42:49 <franck> CS: if we focus on unencrypted content, try to keep content protection elsewhere, req 6 should be fulfilled ?

15:43:23 <trackbot> Created ACTION-97 - Ping D. Singer on requirement 5 [on Clarke Stevens - due 2012-04-05].
15:43:47 <franck> MW: ask Chrome guys
15:44:58 <franck> CS: content protection: is there anything that would prevent open source browser to implement ABR with a proprietary decryption part ?
15:45:43 <franck> MW: need to make sure that jscript will be able to access segment info and timing info
15:46:02 <franck> MW: ...independently from how it has been encrypted

15:47:24 <franck> CS: Req 8: (linked to Req4), content must be identifiable
15:48:11 <franck> MW: HLS/DASH, which profile, or whatever, would be handled by the script, thus does not apply to media source extension

15:51:46 <franck> MW: talking about browser doing the feztching itself , instead of XHR
15:52:07 <franck> MW: some interactions there, maybe with errors ?
15:52:40 <franck> CS: We'll assume it's OK and somebody to speak if not
15:53:20 <Zakim> +Jason
15:53:25 <franck> MV: case where splicing ad into the media: ?
15:53:52 <franck> MW: use another media element to render the ad

15:54:36 <franck> CS: Please provide text on the wiki
15:54:42 <franck> MV: OK
15:55:24 <kaz> s/feztching/fetching/
15:56:10 <franck> MW: you would need some changes in the API to perform this use case
