1427181 - Media Recorder API is not working correctly

Status: RESOLVED DUPLICATE of bug 1411857

(Firefox :: Untriaged, defect)

Description

[VladyslavZotov]

Attachment: firefox.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36

Steps to reproduce:

- start the recording like MediaRecorder.start(100)


Actual results:

receive handle data available event each 100ms, but with empty data and only 1-2 second time period I have data in dataAvailableEvent with data for this long time period

looks like 100ms is ignored during start(timeslice) method


Expected results:

should be like in Chrome, every event calls must have recording data for 100ms time period

You're right. Luckily we have another issue on file with a fix in the works for this one.

And technically the spec doesn't mandate that blobs be non-empty. Just that you need the concatenation of all blobs for a playable file. However, I agree it would be good for convenience.
