Reads stream from file with meta-data headers. Headers are parsed into tags.

The information in the metadata headers includes: Any item inside of the extra header dictionary is ready out and made into a stream tag.


(R): Run-time adjustable

File (R)
Name of the file to read from
Repeat (R)
Repeats file when EOF is found.
Detached header
Set to true if header info is stored in a separate file
Header file
Name of detached header file if used. Defaults to 'filename.hdr' if detached_header is true but this field is an empty string.

Example Flowgraph[edit]

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
