warn when loading corrupted file

[Be]

I was playing a FLAC file that I did not know was corrupted and the audio suddenly stopped. Mixxx kept scrolling the waveform. I tried playing the file with mplayer and confirmed that it was corrupted. It would be great if Mixxx could detect this when a track is loaded and warn the user.

Decoding is done on demand in chunks and decoded chunks are cached. Each decoding operation is preceded by a random seek operation in the audio stream.

We are not able to determine in advance if one of the seek and following decoding operations might fail. This would only be possible by decoding and buffering the whole audio stream in advance.

Is there anything to be done here? I think if we detect corruption while loading it (bad headers, etc.) then we already bail on loading it w/ a warning. In Bug #1793387 we're actually making MP3 decoding more likely to bail on the fly by stopping decoding the moment we detect something bad.

What else can we do? If we detect corruption ever, we can set a flag in the library to warn users about future uses?

Do you still have that corrupt FLAC? It would be nice to test what Mixxx does with it now.

Can this be considered as fixed?
