FS#11124 - Flac decoding of large/high quality file fails

My Ipod 5G (30GB) won’t play a flac file.
The file is very large, 3.12GB since it is encoded as 96kHz and 24bit and almost 3 hours long.
My Rockbox Version is: r25117M-100311

Hi, the rockbox flac decoder is limited to a max blocksize of 4608 samples. could you cjeck the maximum blocksize in this file?
This can be done with the “flac” utility like this “flac -a file.flac” this will write a file.ana file which contains a lot of info from your file, search this file for lines containing blocksize=<something> where <something> is larger than 4608

edit: you can losslessly re-encode your file to a smaller blocksize if this is the case
