Enhancement? ni RD for info.

Comment 5

[David Flanagan [:djf]]

This line from the logcat is important:

12-17 14:03:02.360 E/GeckoConsole( 6419): Content JS ERROR at app://video.gaiamobile.org/gaia_build_defer_index.js:519 in getMetadata/offscreenVideo.onerror: Can't play video /sdcard1/NaviM11/meetthecubs-mp2-audio.mp4 [object Event]

This message comes from apps/video/js/metadata.js:184. It means that gecko is triggering an error event when we try to load the video into an offscreen element.

It is not a gaia bug. And desktop Firefox can play this video, so maybe it is not a gecko bug either. I'm not sure who could help with this.

This issue verified failed on nexus 5 2.2.

Comment 10

[Blake Wu [:bwu][:blakewu]]

I can take a look.

Comment 11

[Blake Wu [:bwu][:blakewu]]

From the logs shown below.
It looks Google's audio decoder failed to decoded this audio data. 
I believe nexus 5 with Android version can hit this problem as well.

Alissa, 
Per comment 11, could you help to check if the testing file can be played on nexus 5 (Android version) or not?

I will check it.

As I know, mpeg2 decoder is subject to a royalty fee. Google decoder doesn't support it.

Comment 15

[Blake Wu [:bwu][:blakewu]]

By checking with ffmpeg -i, the audio part is mp3 which should be supported by Google.

The same video can be recongnized on android nexus 5, but while we play it, it prompt "Can't play video"

Comment 17

[Blake Wu [:bwu][:blakewu]]

Hi djf,

IIRC for those files we cannot play or fail to generate thumbnail, there still would be an icon in the thumbnail list of video app to let user know there is some media file in the storage but cannot be played. 
I don't see that in v2.2 and v3.0. Has that been removed?

Comment 18

[David Flanagan [:djf]]

Blake: I've seen that requested as a feature, but it is not something that we ever implemented. All of the media apps just ignore any media files that they do not know how to play.

Got it. Thanks!

Comment 20

[Blake Wu [:bwu][:blakewu]]

Since the testing file is not a normal file which either contains the wrong mime type or its format not supported by the current Google's mp3 decoder which Android uses and FFOS currently uses as well, change the status of this bug to be wontfix.

It's weird that mediainfo show different result.

Audio
ID                                       : 2
Format                                   : MPEG Audio
Format version                           : Version 1
Format profile                           : Layer 2

Google use mp3 decoder for all tracks with mime type audio/mpeg.
