Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
| # TURN OFF HDMI if not in use | |
| # Get the current video output type and strip away the unimportant bits | |
| video="$(tvservice -s | sed "s/^.*\[\([^ ]*\) .*$/\1/" )" | |
| if [ "$video" != "HDMI" ]; then | |
| printf "HDMI not detected. Turning off.\n" | |
| tvservice -off > /dev/null | |
| else | |
| printf "HDMI detected.\n" | |
