Playing video with "?play=true"

[marcchapeau]

Thank you for this good meteor package.

When I upload a video file and I try to play it on Google Chrome (Desktop), it works perfectly but with an other browser, for example Mozilla Firefox, you can just read the first few seconds an it stops. And with Safari it just does not work.

You can experiment that with the Meteor-Files live demo. Upload the demo video file of the VideoJS website (playing well on all the browser mobile/desktop).

Thx.

Hi @marcchapeau ,
I'm glad you like this package.

I believe your issue is related to #53
Please confirm you're converting video to required formats to support all browsers, see caniuse video

But at the same time it is not explains why video stops. In terms of demo app (hosted on meteor) it may be speed issue, as meteor platform for demo apps is not good in performance and speed. Have you tested it locally?

[marcchapeau]

Thx for your answer.

Yes, I tested it locally and on production with my own dedicated server with the same result. As I said, the demo video file of VideoJS works on all browser so it is probably not a video format issue. The only difference i can see is that on VideoJS, the video is directly served from server and with your package and the "?play=true" request the video is manually served with partial-range http request. Of course, I tried to directly put the same video file in the meteor public folder and it works perfectly (without using your package).

Maybe this is due to the implementation of the "partial-range" between the different browsers...

Thanks for your help.

partial-range is tested on most browsers in major version. If wrong part or length of chunk is returned in headers, you should see error in "Network" tab of dev-tools (in Chrome for example). Are you sure file is served by Meteor (nodejs), not a proxy server, like nginx or Apache?

1. Do you have any errors, js or network, or any other?
2. You're playing video by build-in video tag or with using third-party js-video-player?

[marcchapeau]

With Chrome in network tab of dev-tools i can see each partial-range request without problem. With Firefox, it's strange because there is no line representing the partial-range request.
When i try this on my own environnement, i get exactly the same result with your live demo. I just uploaded the video on your demo website.

I think this is not an environnement problem.

Sorry for your time but I try to solve this problem without success and your package is the only one working good to upload and serve video file with meteor (except this little problem ^^)

[dr-dimitru]

Confirmed, only in FF.
What I see right now, the FF is not requesting next chunk from server after receiving 206 response code, and keeps playing first chunk. On screenshot you can see correct response and headers.

Could you please try third-party player, it should fix this issue, as they know how to handle such cases.
Or try to use link without ?play=true query, and/or try to use ?download=true query (both methods will increase sever's CPU and memory usage).

Sorry, I but I don't have time now to code and play around with settings. But I'm able to answer for any further questions. And do not forget to tell about your solution.

Hey @marcchapeau ,
Any news on your end?

[marcchapeau]

Sorry, I was working on another project.

But yes, I have some news. I tried a third party player (videoJs) and there is the same problem. With Chrome, it works perfectly and with FF always the same first chunk.

I tried with and without ?play=true, and with ?download=true but there is always the problem. The only difference is with ?download=true, you can right click on the video player to download the file. Without ?download=true or with ?play=true, the dowloaded file is an empty file.

So sorry but i did not find a solution to solve this problem...

@marcchapeau I've called for help of community, you may would like to spread it bigger (as i don't have much followers).
Or/and aside to it, you can ask on SO. Reference this thread, with tags of firefox, node.js, a/v streaming, meteor

[dr-dimitru]

@marcchapeau any news around this issue?

[dr-dimitru]

Hi @marcchapeau could you please check on your end, if this issue is solved at latest release?

[marcchapeau]

Sorry but unfortunately the problem does not seem to be resolved.
With Chrome it works well, but with FF only the the first chunk is sent to the browser.

Thank you for the support of Meteor 1.3.

[dr-dimitru]

Heads up, this issue was solved in 1.4.0, could you please confirm on your end?

BTW if you're curious what it was caused by, read:

• Mozilla Bug 1182869
• Mozilla Bug 570755
• In a short form: Do not use Content-Length within Content-Encoding: chunked and 206 response code
