Bug Description

Binary package hint: soundconverter

I have about 6000 flac files laid out in artist/album fashion. I am using Lucy 64 bit on an 8 core machine with 8 Gig mem. I have configured Soundconverter to output to my Music folder in my home account. I navigate to the top of my flac music collection using Nautilus then select all the albums with a CTRL-A. I then drag this set onto Soundconverter. The UI becomes very sluggish - but within about 5 seconds allows me to press the 'Convert Button'. I see many folders created in the destination directory and I see that Soundconverter is indeed producing ogg files. However, after a little more than 1 minute, Soundconverter reports 'Conversion done, in 1 m 12 s'. Is is not done. And the UI remains extremely slow. I do not know if it is continuing as there is no load on my CPUs. Perhaps there is a race condition that is not CPU bound? Some of the items in the list indicate 'loading tags...' I see network traffic in a regular pattern. Then, the status went to 'Ready' and there are still plenty of files that are not converted. At this point I hit 'Convert' again. Then told it to skip files that were already there and apply that to entire queue. A guess is that the conversion activity only applies to the files that have had their tags loaded at the moment the convert button is pressed? Perhaps one queue should back-fill the other? As tracks become available for conversion they are posted to the conversion queue?

SoundConverter was designed to converter hundred of files, not thousands.
And you are absolutely right, SoundConverter can only convert files when their tags have been read.
Even if they are not used. This will be fixed in 2.0.
For now, wait for all the tags to be read (the status will display "Ready"). Maybe we should de-sensitive the convert button when loading?

I didn't see you were using 1.4, so:

The loading of thousands of files is massively faster and better optimized for multiple cores, you should try it.
