A Falcon Pi Player fseq (v2) sequence file parser.

pip install fseq

To use the project:

import fseq

f = open('filename.fseq')
fseq.parse(f)

The parse function returns a Fseq object with the following properties:

• file: the underlying file object
• version: a 2-tuple of numbers containing major and minor version
• minor_version: the minor version number
• major_version: the major version number
• channel_count_per_frame: the amount of channels in each frame
• number_of_frames: the total number of frames in this sequence
• step_time_in_ms: the number of milliseconds between each frame
• unique_id: a unique indentified
• compression_type: the compression type used for frames, either none, zstd, zlib
• variable_headers: an array of 2-tuples containing key-value pairs describing additional headers for the sequence file

To access a single frame data use the get_frame(index) method on the Fseq object. Use index access to read channel values:

frame = fseq_file.get_frame(index)
value = frame[channel_num]

To run the all tests run:

tox

• Add support for fseq files without compression
• Add support for fseq files with Zlib compression
• Add support for fseq files with sparse ranges
• Add support for writing fseq files
