Audio Player: actions

[qtipee]

Implementation of the following actions:

• Next
• Rewind
• Previous
• Repeat
• Random

[qtipee]

The « Next » and « Previous » actions are implemented (see issue #5).

[qtipee]

A constant defines from which currentTime the « Previous » action rewinds the current audio file (3 seconds) ; when the currentTime is smaller than this constant, the previous audio file is set and then played.

A click on the « Random » button plays a random audio file, and keeps playing another random audio file whenever the « on ended » event is triggered. To cancel it, just click on an audio file. Each randomly played audio file is pushed in a history list ; it allows to play back the previous audio files. However, I'm not satisfied with the current behaviour of the « Random » action ; I think it would be better to have something similar to Spotify : the « Random » action is like a checkbox and there is a « Play/Listen » button to start the tracks.

I'm also not satisfied with the code ; it needs to be reviewed, refactored and simplified.

I have spent too much time on this issue ; I'm letting it open and will come back to it as soon as possible to improve the random behaviour and the corresponding code.
