@baccola-- Could you please provide the sample url / test case ,that would help us in reproducing the issue .

Thanks!

IP multicast streams have to be generated from servers that are on the local network that the viewer is on and the network has to be configured to allow the IP multicast streams to be distributed (routers and switches have to allow for the RTMFP streams to pass through them).

We could certainly help set up an on prem AMS server to generate the streams and we could help run test streams for you.

Thank you for providing feedback. removing "Needs-Feedback" label.

This looks like out of scope for TE, hence adding the respective label for it to  triage further.

baccola@mediaplatform.com, please provide a repro url for us to repro. 

Hi Yini - 

Hdodda asked that earlier in the thread also.  You guys are missing a fundamental part of IP multicast and that is that video streams for IP multicast CAN NOT traverse the open internet.  IP multicast streams have to be created by a media server that is on the viewers network and the network that the viewer is on must be configured to allow the IP multicast streams to be distributed (so the routers and switches on the network have to be configured to allow for the multicast traffic to pass through them).

This means that I can't provide you with a stream URL to test with.  A couple of years ago there was a bug that broke IP multicast in Chrome all together.  Here is a link to the bug tracker on that:  https://bugs.chromium.org/p/chromium/issues/detail?id=243700

Maybe one of the people that worked on that bug could help on this one.  I know that some of the developers on that thread asked if we could provide a test stream then also.  To get that bug solved they had to have set up a test environment somewhere that you can use.

We are happy to help in anyway we can.  If you get an Adobe Media Server set up, we can help configure it and get test coming out of it for you.

Thank you for providing more feedback. Adding requester "yiningc@chromium.org" to the cc list and removing "Needs-Feedback" label.

I have this issue when using Chrome to view internal multicast streams sourcing from an AMS server.  We are using Adobe Flash to play the stream.  We view intermittent pixilation when viewing feeds. We have tried increasing the buffer but with no change in behavior. The buffer does not empty even with the additional buffer time.  Can we set up a time to show you the behavior? Thx

Chrome and multicast streaming is not an acceptable experience at GM.  WE have extremely long load up times( over 3 mins.) and heavy pixelization once stream starts ( see whenever there is high motion or change in stream).  I am at Chrome 56.   We are informing users not to use chrome because of this issue

Hdodda/Yini,


Hello, I would like to get this issue progressing towards a solution again as it seems to have stalled a bit. I have tested internally the Media Platform software using Google Chrome for Windows and Linux. I have found that this poor video playback issue is in fact only present in Chrome/Chromium on every OS tried when using Multicast as the stream source. 

Due to the nature of Multicast networking, we are unable to provide a stream for testing over the internet, this type of networking does not propagate over the internet with any reliability.

I think it would be best to setup a meeting to discuss this issue in further detail, and even demonstrate the problem for you to see. Also, if possible to help Google in setting up a lab environment to further test/diagnose this problem. 

I will be the primary point of contact for Media Platform on this, in the meantime I will continue some in house testing for workarounds/solutions to this problem, is there any further data that Google would like to see from this issue?

Adding Adobe folks.

Any updates on this?  We get asked at least weekly for progress updates.

@baccola@mediaplatform.com We are waiting for engineers from mediaplatform to continue the test. Last time, the test video streaming did not work on Chrome, only audio was played, I was told that they will fix the stream for Chrome first. So I am waiting until now.

I think there might be a miss understanding.  You might be waiting for Adobe staff to create the streams for you.

Issue has not been modified or commented on in the last 365 days, please re-open or file a new bug if this is still an issue.
