After installing NOOBS you will have this sdcard partition table (eg. 16GB sdcard):
1 | root# sfdisk -d /dev/mmcblk0
|
1 2 3 4 5 6 7 8 9 10 | label: dos label-id: 0x00084f9c device: /dev/mmcblk0 unit: sectors /dev/mmcblk0p1 : start= 8192, size= 2280871, type=e /dev/mmcblk0p2 : start= 2289063, size= 28827225, type=5 /dev/mmcblk0p5 : start= 2293760, size= 65534, type=83 /dev/mmcblk0p6 : start= 2359296, size= 129024, type=c /dev/mmcblk0p7 : start= 2490368, size= 28625920, type=83 |
and we have to create another one like this (eg. 32GB sdcard):
1 2 3 4 5 6 7 | label: dos label-id: 0x00084f9c device: /dev/sdc unit: sectors /dev/sdc1 : start= 8192, size= 85405, type=c /dev/sdc2 : start= 94208, size= 62239744, type=83 |
save the last output to a file sdcard.ptable and:
1 2 3 4 5 6 7 8 9 10 11 12 13 | # write partition table sfdisk /dev/sdc < sdcard.ptable # format partitions mkfs.vfat -v /dev/sdc1 mkfs.ext4 -m 1 -b 4096 -O ^metadata_csum -v /dev/sdc2 mkdir src dst # copy partition 1 data mount /dev/mmcblk0p1 src mount /dev/sdc1 dst rsync -avihh --stats --progress --inplace --delete --delete-before --delete-excluded src/ dst/ |
edit cmdline.txt and set the correct boot partition with root=PARTUUID=00084f9c-02, then:
1 2 3 4 5 6 7 | umount src dst
# copy partition 2 data
mount /dev/mmcblk0p1 src
mount /dev/sdc1 dst
rsync -avihh --stats --progress --inplace --delete --delete-before --delete-excluded src/ dst/
umount src dst
|
and edit etc/fstab with the correct partition labels :
1 2 | PARTUUID=00084f9c-01 /boot vfat defaults 0 2 PARTUUID=00084f9c-02 / ext4 defaults,noatime 0 1 |
Note: Alternatively you can also update the NOOBS installer.

FFmpeg convert-all
Install ffmpeg:
1 2 3 4 5 6 | # debian 8 jessie apt-get install libav-tools alias ffmpeg=avconv # put this in your ~/.bashrc # debian 9 stretch apt-get install ffmpeg |
or just download a static build from the nice John Van Sickle (choose armhf-32bit for the raspberry pi).
Then use it to convert all your files:
1 2 3 | for f in *.flac , *.m4a , *.ogg ; do ffmpeg -i "$f" -ab 320k "${f%.m4a}.mp3" done |
Note: In case of Too many packets buffered for output stream error use -max_muxing_queue_size option with a higher number (start at 1000).
FLAC to MP3 via custom encoder
1 | flac -c -d in.flac | lame -m s -h -b 256 - out.mp3
