flac tracks skipped after playing a few seconds

[jlcharrier]

Hello
I'm using UPnP/DLNA
My encoder is Exact Audio Copy (EAC).
Has ffmpeg something to do with UAPP ?
My problem is that I have thousands of encoded flac files. I cannot afford to rencod them. (One CD takes about 8 minutes or more...).
Is there a solution to reencode them from file to file (i;e; not from the cd) ?
Any other solution ?
Thanks
