491410 - Unsupported .wav formats cause "ABORT: Invalid state transition:" assertion failure.

Status: RESOLVED DUPLICATE of bug 481057

(Core :: Audio/Video, defect)

Description

[Sylvain Pasche]

Attachment: ITU G.711 mu-law, mono 8000 Hz sample .wav file

I noticed this when trying to open a .wav file from bug 491385 (dup of 475110).

The wave file in question is compressed PCM:

file 8kulaw.wav 
8kulaw.wav: RIFF (little-endian) data, WAVE audio, ITU G.711 mu-law, mono 8000
Hz

Then you get:
WARNING: WAVE is not uncompressed PCM, compressed encodings are not supported: file mozilla/content/media/video/src/nsWaveDecoder.cpp, line 1019
###!!! ABORT: Invalid state transition: 'IsValidStateTransition(mState, aState)', file mozilla/content/media/video/src/nsWaveDecoder.cpp, line 819

In a non-debug build, the spinner keeps spinning. Ideally there should be some kind of UI notification when the .wav file is broken instead.

We need to fire decode errors for this case, but some of the code isn't implemented yet.  There's a bug for doing so: bug 481057.

Once we fire these events, the UI should show the "broken file" icon, since it is already wired up to do this for the other types of media errors that can happen.
