Hi,
I'm trying to read some files (video files) that seems to have some
errors in it. Basically, I cannot copy it out of discs as that gives me
an error message but I can still play the file using a media player like
VLC or QuickTime. I understand that copying a file will also invoke
checking routines as well, and I am guessing that the file may have some
parity-bit error or something.
Am I able to use Python to force read the entire file (full length)?
That is, do not check the read for errors. I know that this is insideous
in many uses but in media files, it may only result in a skipped frame
or something. What I've done is something like this:
>>> f = open('/Volumes/NEW/gameday/morning.dat', 'rb')
>>> data = f.read()
>>> o = open('/Users/mauriceling/Desktop/o.dat', 'wb')
>>> f.close()
>>> o.write(data)
>>> o.close()
What I've noticed is this:
1. sometimes it (Python) only reads to roughly the point of initial copy
error (I try to take note of how far drag-and-drop copying proceeds
before it fails)
2. sometimes it is able to read pass the drag-and-drop copying
fail-point but may or may not be full length.
What determines if Python is able to make it pass drag-and-drop copying
fail-point?
Is there anyway to do what I want, force read full length?
Thanks and cheers
Maurice
