IE11 Live stream playback issue #290
Comments
@neilRGS, |
@peyoh. Hi. I am using 1.6.3 |
Please revert to 1.6.2 and try again. |
@peyoh. Will do. I'll post the result of doing that, here. |
@peyoh. I have downloaded, built and tried 1.6.2 Thanks. |
@neilRGS Thank you for your time.
BRS, |
Hi @peyoh. I had a look at https://html5test.com/ and it shows that IE11 does not support Promise. As there are plenty of Promises in the Shaka code, perhaps that is a major issue. If so, I wonder why the Shaka docs suggest that IE11 is ok? Ultimately, as IE11 is a browser in use by a good many of our clients, I am going to have to find something else which will work without flash being installed. Many thanks again for your help and input, it is appreciated. Neil. |
Hi @peyoh. I have tried using a polyfill and this now shows in the support page that Required Features is 'OK'. I can rule out encoding issues, because I get successful playback in Firefox, Chrome & Edge with both live and VOD. In IE11 only VOD plays successfully. So, no further on really, but I wanted to add that extra info, for anyone else reading this, experiencing the same problem. Many thanks Neil. |
@neilRGS @peyoh Shaka support for live on IE11 starts with v2, which has not been released yet. In v1, we expect that we can set We expect v2 beta to be available in a week or two. Thanks! |
Hi @joeyparrish If it helps any, I have had a certain amount of success with Dash.js and IE11. It is not production quality though, as it will stream for a while and then seems to get stuck in a loop and then continues etc... Have a good weekend, Neil. |
Thanks, Neil. We are reasonably confident that v2 will solve this for you, since v2's |
Hi Joey. Any update on the release of v2 at all? Thanks in advance, Neil. |
We expect a beta by the end of the month, which we will announce on the mailing list. |
@neilRGS, can you please try with the latest from master? We just released v2-beta. If it still does not work for you, can you provide a link to your manifest? |
Will do, Joey |

Hi Joey. I have just spun up a demo to play with v2. I have followed the instructions at http://shaka-player-demo.appspot.com/docs/api/tutorial-basic-usage.html but am unfortunately stumped by this error: Has the shaka object been renamed to something else in an update, perhaps? Many thanks and best regards, |
UPDATE: Working. ☺ About to do more testing. Best regards, Neil. |
Hi Joey. The manifest is generated by our Wowza server and is this: +++++++++++++++++++++++++++++++++++++++++++++++ |
Hi, I am able to reproduce the issue on IE11 on Windows 10. I see that the content works on Chrome Linux and Chrome Windows. Also, I see that the default Wowza test asset works fine on IE11 too. Nothing obvious seems wrong, so I'll have to investigate further. |
I am able to reproduce in both IE11 and Edge, but on a system with known-bad clock-sync. If I hack a |
I'll take a look and see if I am able to do that. |
Without a UTCTiming element in the manifest, a client cannot synchronize its clock. This can easily lead to playback failures, so we warn application developers when we detect this. Issue #290 Change-Id: Idcb395f5ece67bf2c7d0d984ad277f552d030eb8
@neilRGS, we've added two things to help with this. One is a warning when UTCTiming is missing, and the other is a config option to specify a clock sync URI outside of the manifest. Please let us know if this helps. |
Hi.
I am having trouble with Live stream playback through IE11. The player loads on screen and then nothing further happens.
UPDATE:-----:
Looking in IE developer tools, I can see that the manifest is being read every 10s (approx)
VOD playback works fine.
Below is the output from the browser support page, viewed through IE11:
Thanks in advance for any advice you can give.
Neil.
