Subject [jira] [Commented] (CB-6051) video / audio won't play from cdvfile:// urls

Claudius Coenen commented on CB-6051:
-------------------------------------

I can't verify it right now, but looking at the filenames in those chagesets, i'd like to
ask if this fixes video and audio, or if it's fixing Audio only.
I am just asking, because the changed files are CDVSound and AudioHandler.

>                 URL: https://issues.apache.org/jira/browse/CB-6051
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Plugin File, Plugin Media
>    Affects Versions: 3.3.0
>         Environment: iOS
>            Reporter: Claudius Coenen

> We have an application that used to work in Cordova 2.9, we think we have traced down
the error to cdvfile://. Here's what's happening:
> *The Application*
> We're loading a few videos and a HTML-File referencing those videos into the app, using
{{FileTransfer}}. This transfer is fine now, and we _can_ access and display the HTML-File
and other assets like images. The videos on this page however won't play. They display as
"broken" (strike-through play symbol on iOS). We know the videos to run, it's not the video's
encoding, we also triple-checked all the filenames as well. If we pre-package the video into
the app, the same setup _does_ play just fine.
> *Behaviour Cordova 2.9*
> We're getting the just-downloaded html file from the filesystem and call {{toURL()}}
on that entry. In 2.9 this will return a lengthy (but working) {{file:///}}-url. We're basically
setting
> {{window.location = entry.toURL(); // returns file:///...}}
> *Behaviour Cordova 3.3*
> When calling {{toURL}}, we're now getting a {{cdvfile://}} URL, and (since the video
file is referenced relatively) the video is also loaded from a {{cdvfile://}} URL.
> *Why i believe the cdvfile:// to be at fault*
> Basically "it used to work". We're suspecting that the file-protocol emulates a lot of
the iOS-y stuff when it comes to video. Possibly the Content-Type-Header and the Range-Header
that iOS uses extensively for streaming the video from a webserver.
> For an audio file, we're getting log-lines reading "_itemFailedToPlayToEnd: {kind = 1;
new = 2; old = 0;}"
> I did not find any way to get a {{file:///}}-URL out of cordova 3.3, but i am pretty
sure that this would cure my immediate problem.
