siddec

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

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

Decode a sid file and play it back.
