Description

This element decodes .sid files to raw audio. .sid files are in fact small Commodore 64 programs that are executed on an emulated 6502 CPU and a MOS 6581 sound chip.

This plugin will first load the complete program into memory before starting the emulator and producing output.

Seeking is not (and cannot be) implemented.

Example pipelines

1	gst-launch-1.0 -v filesrc location=Hawkeye.sid ! siddec ! audioconvert ! audioresample ! autoaudiosink

Decode a sid file and play it back.
