20948 2013-02-11 14:32:35 +0000 timestampOffset should reopen media source just like append 2013-02-19 01:03:29 +0000 1 1 1 Unclassified HTML WG Media Source Extensions unspecified All All RESOLVED FIXED P2 normal --- 1 adrianba acolwell acolwell mike public-html-media public-html-bugzilla oldest_to_newest 82897 0 adrianba 2013-02-11 14:32:35 +0000 Currently step 5 of the appendArrayBuffer|Stream methods reopens the media source if its state is "ended". However, the timestampOffset throws INVALID_STATE_ERR in this situation. This means that if you can't set the timestamp offset and then append without doing something else to cause the media source to be reopened first. Proposal: Change step 3 of the timestampOffset property setting to match steps 4 and 5 of appendArrayBuffer: "If the readyState attribute of the parent media source is not in the "open" state, then throw an INVALID_STATE_ERR exception and abort these steps." becomes "If the readyState attribute of the parent media source is in the "closed" state then throw an INVALID_STATE_ERR exception and abort these steps. If the readyState attribute of the parent media source is in the "ended" state then run the following steps: 1.Set the readyState attribute of the parent media source to "open" 2.Queue a task to fire a simple event named sourceopen at the parent media source." 82918 1 1326 adrianba 2013-02-11 17:57:58 +0000 Created attachment 1326 Proposed patch Proposed patch updating the steps for timestampOffset. 83298 2 acolwell 2013-02-19 01:03:29 +0000 Changes committed. https://dvcs.w3.org/hg/html-media/rev/d5956e93b991 Proposed patch applied. 1326 2013-02-11 17:57:58 +0000 2013-02-11 17:57:58 +0000 Proposed patch timestampOffset-reopen.patch text/plain 2146 adrianba ZGlmZiAtciA3Nzk3NWFiZWVjNDEgbWVkaWEtc291cmNlL21lZGlhLXNvdXJjZS1yZXNwZWMuaHRt bAotLS0gYS9tZWRpYS1zb3VyY2UvbWVkaWEtc291cmNlLXJlc3BlYy5odG1sCVRodSBKYW4gMzEg MTQ6MjA6NTQgMjAxMyAtMDgwMAorKysgYi9tZWRpYS1zb3VyY2UvbWVkaWEtc291cmNlLXJlc3Bl Yy5odG1sCU1vbiBGZWIgMTEgMTI6NTY6NTQgMjAxMyAtMDUwMApAQCAtMSw0ICsxLDQgQEAKLTwh RE9DVFlQRSBodG1sIFNZU1RFTSAiYWJvdXQ6bGVnYWN5LWNvbXBhdCI+Civvu788IURPQ1RZUEUg aHRtbCBTWVNURU0gImFib3V0OmxlZ2FjeS1jb21wYXQiPgogPGh0bWw+CiAgIDxoZWFkPgogICAg IDxtZXRhIGh0dHAtZXF1aXY9IkNvbnRlbnQtVHlwZSIgY29udGVudD0idGV4dC9odG1sOyBjaGFy c2V0PXV0Zi04Ij4KQEAgLTY4MCw3ICs2ODAsMTYgQEAKICAgICAgICAgICA8b2w+CiAgICAgICAg ICAgICA8bGk+SWYgdGhpcyBvYmplY3QgaGFzIGJlZW4gcmVtb3ZlZCBmcm9tIHRoZSA8YSBkZWYt aWQ9InNvdXJjZUJ1ZmZlcnMiPjwvYT4gYXR0cmlidXRlIG9mIHRoZSA8YSBkZWYtaWQ9InBhcmVu dC1tZWRpYS1zb3VyY2UiPjwvYT4sIHRoZW4gdGhyb3cgYW4gPGEgZGVmLWlkPSJpbnZhbGlkLXN0 YXRlLWVyciI+PC9hPiBleGNlcHRpb24gYW5kIGFib3J0IHRoZXNlIHN0ZXBzLjwvbGk+CiAgICAg ICAgICAgICA8bGk+SWYgdGhlIDxhIGRlZi1pZD0idXBkYXRpbmciPjwvYT4gYXR0cmlidXRlIGVx dWFscyB0cnVlLCB0aGVuIHRocm93IGFuIDxhIGRlZi1pZD0iaW52YWxpZC1zdGF0ZS1lcnIiPjwv YT4gZXhjZXB0aW9uIGFuZCBhYm9ydCB0aGVzZSBzdGVwcy48L2xpPgotICAgICAgICAgICAgPGxp PklmIHRoZSA8YSBkZWYtaWQ9InJlYWR5U3RhdGUiPjwvYT4gYXR0cmlidXRlIG9mIHRoZSA8YSBk ZWYtaWQ9InBhcmVudC1tZWRpYS1zb3VyY2UiPjwvYT4gaXMgbm90IGluIHRoZSA8YSBkZWYtaWQ9 Im9wZW4iPjwvYT4gc3RhdGUsIHRoZW4gdGhyb3cgYW4gPGEgZGVmLWlkPSJpbnZhbGlkLXN0YXRl LWVyciI+PC9hPiBleGNlcHRpb24gYW5kIGFib3J0IHRoZXNlIHN0ZXBzLjwvbGk+CisgICAgICAg ICAgICA8bGk+SWYgdGhlIDxhIGRlZi1pZD0icmVhZHlTdGF0ZSI+PC9hPiBhdHRyaWJ1dGUgb2Yg dGhlIDxhIGRlZi1pZD0icGFyZW50LW1lZGlhLXNvdXJjZSI+PC9hPiBpcyBpbiB0aGUgPGEgZGVm LWlkPSJjbG9zZWQiPjwvYT4gc3RhdGUgdGhlbiB0aHJvdyBhbiA8YSBkZWYtaWQ9ImludmFsaWQt c3RhdGUtZXJyIj48L2E+IGV4Y2VwdGlvbiBhbmQgYWJvcnQgdGhlc2Ugc3RlcHMuPC9saT4KKyAg ICAgICAgICAgIDxsaT4KKyAgICAgICAgICAgICAgPHA+SWYgdGhlIDxhIGRlZi1pZD0icmVhZHlT dGF0ZSI+PC9hPiBhdHRyaWJ1dGUgb2YgdGhlIDxhIGRlZi1pZD0icGFyZW50LW1lZGlhLXNvdXJj ZSI+PC9hPiBpcyBpbiB0aGUgPGEgZGVmLWlkPSJlbmRlZCI+PC9hPiBzdGF0ZSB0aGVuIHJ1biB0 aGUgZm9sbG93aW5nIHN0ZXBzOjwvcD4KKyAgICAgICAgICAgICAgPG9sPgorCSAgICAgICAgPGxp PlNldCB0aGUgPGEgZGVmLWlkPSJyZWFkeVN0YXRlIj48L2E+IGF0dHJpYnV0ZSBvZiB0aGUgPGEg ZGVmLWlkPSJwYXJlbnQtbWVkaWEtc291cmNlIj48L2E+IHRvIDxhIGRlZi1pZD0ib3BlbiI+PC9h PgorICAgICAgICAgICAgICAgIDwvbGk+CisJICAgICAgICA8bGk+CisgICAgICAgICAgICAgICAg ICA8YSBkZWYtaWQ9IlF1ZXVlLWEtdGFzay10by1maXJlLWFuLWV2ZW50LW5hbWVkIj48L2E+IDxh IGRlZi1pZD0ic291cmNlb3BlbiI+PC9hPiBhdCB0aGUgPGEgZGVmLWlkPSJwYXJlbnQtbWVkaWEt c291cmNlIj48L2E+IC48L2xpPgorICAgICAgICAgICAgICA8L29sPgorICAgICAgICAgICAgPC9s aT4KICAgICAgICAgICAgIDxsaT5JZiB0aGlzIG9iamVjdCBpcyB3YWl0aW5nIGZvciB0aGUgZW5k IG9mIGEgPGEgZGVmLWlkPSJtZWRpYS1zZWdtZW50Ij48L2E+IHRvIGJlIGFwcGVuZGVkLCB0aGVu IHRocm93IGFuIDxhIGRlZi1pZD0iaW52YWxpZC1zdGF0ZS1lcnIiPjwvYT4gYW5kIGFib3J0IHRo ZXNlIHN0ZXBzLjwvbGk+CiAgICAgICAgICAgICA8bGk+VXBkYXRlIHRoZSBhdHRyaWJ1dGUgdG8g dGhlIG5ldyB2YWx1ZS48L2xpPgogICAgICAgICAgIDwvb2w+Cg==
