A quick guide on how to read/write/modify ID3 metadata tags for audio / media files using ffmpeg.
FFmpeg has a free-form command line option that allows the user to specify key-value-pairs for encoding metadata. Let's take a look.
To list all global metadata tags for a media file, just set an input but no output file.
| [general] | |
| version = 4 | |
| name = Anet A6_settings | |
| definition = custom | |
| [metadata] | |
| setting_version = 5 | |
| type = definition_changes | |
| [values] |
This walks you through installing JACK, connecting a USB sound card, and copying the audio on the input port onto the output port. The result: you will hear what you say played back immediately from the headphones.
sudo pip install setuptools
sudo apt-get install python-dev
sudo apt-get install libffi-dev
Make sure the if value is correct! If doing this over SSH then open a TMUX session first... or else...
dd if=/dev/YOUR-DEVICE conv=sync,noerror bs=64K | gzip -c > /home/portaj/macbook.img.gz
NOTE: You might not want to compress the image. It just means you have to uncompress it later to mount it. If you're planning to access the data soon, or frequently, don't compress it.
Save it in the same directory as the compressed image so later on if you decide you want to mount or extract data from the image you can see the partition structure without having to decompress the whole image. There might be some other ways to mount a compressed image.
