1374026 - getUserMedia recording (video/webm) done in chrome not playable in firefox.

Status: RESOLVED INVALID

(Core :: WebRTC: Audio/Video, defect)

Description

[trevordowdle]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170518000419

Steps to reproduce:

Recorded a video in Chrome (getUserMedia - video/webm) uploaded video to amazon s3 storage. 

Load the video using firefox using the direct url to the video/webm file.

See:

https://s3-us-west-2.amazonaws.com/boldvue-video-dev/VideoBlob/6ECCgXnZYC9cujaat/6c6caa44f60f56ce027b0ae3.webm


Actual results:

I get an error:

1.  from the logs:
Media resource https://s3-us-west-2.amazonaws.com/boldvue-video-dev/VideoBlob/6ECCgXnZYC9cujaat/6c6caa44f60f56ce027b0ae3.webm could not be decoded.

2.  In the browser I see the following:
No Video with supported format and MIME type found.
or 
Video format or MIME type is not supported.


Expected results:

I would expect it to play the the video/webm file generated by chrome.

Load the same url in chrome and it plays:
https://s3-us-west-2.amazonaws.com/boldvue-video-dev/VideoBlob/6ECCgXnZYC9cujaat/6c6caa44f60f56ce027b0ae3.webm

This is causing major issues with cross browser functionality.  I can only support chrome or firefox but not both, chrome users who upload videos won't be accessible by firefox users.  Though firefox recordings are loadable in chrome.

Can you tell why the video recorded on Chrome does not work on firefox?

This isn't a valid webm, it has a h264 track.

Per spec, webm is to contain only opus, vorbis, vp8, vp9 (and now av1)

Replace

mimeType: 'video/webm',
to
mimeType: 'video/webm;codecs=vp9',

Chrome Save webm video data with codecs=h264

firefox webm is to contain only opus, vorbis, vp8, vp9
