Recording crash over 3 mins on 720p

@zang can you include the video.js config so I can give it a try? And as always, does this happen with RecordRTC-only examples as well?

[zang]

Here you go:

var player = videojs('myVideo', { controls: true, loop: false, plugins: { record: { audio: true, video: { mandatory: { minWidth: 1280, minHeight: 720, maxWidth: 1280, maxHeight: 720 } }, maxLength: 600 } } });

I tried on the following page and works fine for long recording but apparently it's 480p as I don't see any option to switch to 720p. :)

What page?

@zang with chrome 49 on OSX I've tried with the default settings (320x240) and this created a video/webm -> 74.1 MB file for 9:10 minutes. When I record more than 9:30 the browser crashes, even with 320x240. Need to figure out how to view the crash log.

I've logged a crash report here: https://bugs.chromium.org/p/chromium/issues/detail?id=595442

Thanks @thijstriemstra
I just recorded a 5-min 720p on Firefox (98mb) and it worked. So, I think it's a Chrome issue.

@muaz-khan are you aware of this issue? I vaguely remember you have an example of 60-min recording. If so, how did you do it?

[thijstriemstra]

FYI a Blob in Chrome cannot be bigger than 500MB at the moment according to this bug report and this piece of code but we're not hitting that limit yet are we? An overview of the blob limits for the various browsers is listed here.

@muaz-khan on Chromium I see an actual error and it seems related to RecordRTC: https://bugs.chromium.org/p/chromium/issues/detail?id=595442#c1

[thijstriemstra]

@muaz-khan added a change related to this issue it seems (muaz-khan/RecordRTC@b1e63b0).

[zang]

Thanks @thijstriemstra , and I will try.

I just tried again in Chrome stable 49 and created video/webm -> 173 MB for 10:10 minutes and I didn't get a crash. Tested on:

[zang]

Tested on my machine and it works perfectly. (Closing this ticket)

Chrome 51 introduces async blob construction that should be able to work around this problem, which is enabled in Chrome 57! See https://bugs.chromium.org/p/chromium/issues/detail?id=375297#c107
