Descriptions
Stream output
Doesn't do anything. Can be used to test other stream output chain modules without actually streaming anything.
Options
Dummy decoder
- dummy-save-es <boolean> : Save the raw codec data if you have selected/forced the dummy decoder in the main options. default value: disabled
Video output
- dummy-chroma <string> : Force the dummy video output to create images using a specific chroma format instead of trying to improve performances by using the most efficient one. default value: NULL
