AAFFile
(path=None, mode='r', sector_size=4096, extensions=True, buffering=8192)¶ Bases:
object
AAF File Object. This is the entry point object for most of the API. This object is designed to be like python’s native open function. It is recommended to create this object with the aaf.open alias. It is also highly recommended to use the with statement.
Warning
If an exception is raised inside the with block and the file was opened as writable, the final file should be considered bad or corrupted.
Take this snippet as an example:
try: with aaf.open('/path/to/aaf_file.aaf', 'r+') as f: raise ValueError('asd') except: pass
in this case, even if the exception is properly handled, the content of
/path/to/aaf_file.aaf
shouldn’t be trusted anymore.For example. Opening existing AAF file readonly:
with aaf.open('/path/to/aaf_file.aaf', 'r') as f:
Opening new AAF file overwriting existing one:
with aaf.open('/path/to/aaf_file.aaf', 'w') as f:
Opening existing AAF in read and write:
with aaf.open('/path/to/aaf_file.aaf', 'rw') as f:
Opening in memory BytesIO file:
with aaf.open() as f:
