Most of the episodes work fine now, but i still have some problems.
There are a few which load fine but produce a horrible noise. You can get one of these here.
Also there is one that doesn't load at all : link.

The hiss is a side effect of the decoder running out of memory... :) The other one is a file parsing problem; don't know what just yet.
--- Quote ---And there's one last thing I'd like to mention, it's that your commit said "accept M4B files". Maybe it's not what you meant but I thought I would actually be able to play files with an M4B extension... Maybe as most of them are now playable you could add support for that extension in the browser ?

No, that M4B thing I referred to is something that can be found inside the file. Adding support for the extension could be a good idea.
NicolasP:
How come the decoder runs out of memory on some files and not others ? This is even more surprising as these episodes used to play fine after being modified by my script...

The size of various tables used for seeking (and playback). Your script can change the file layout, and also make some tables more compact. This can reduce the size of the tables, making it possible to load the file.
Btw, the file that didn't load fails because the file isn't streaming friendly (which Rockbox currently requires); the metadata comes after the audio data.
NicolasP:
Thanks for the explanation :) Is there any chance these files will work in the future, or should I just run them through my script ?
Also about the one that wasn't streaming friendly, foobar corrected it perfectly so now it works fine.
Now there is something else I noticed, about replay gain : the value is taken into account (there is a distinct volume jump when I enable/disable replay gain), but in the ID3 info screen, the value shown under "track gain" is the track title ;D I haven't tried album gain...
Finally, would you have any idea on how to read the bookmark time tags stored in these M4B files ? It would be a very nice feature to add and maybe I'd try doing so.
Yotto:
Do the producers of the show not produce a non-enhanced version of their show? As a podcaster (though as one who does not produce an enhanced version) I can't imagine producing ONLY an enhanced podcast, and not also provide a good old fashioned mp3 file as well.
