Corrupt avi help

[wild-paradox]

My suggestion would be to just search the internet for a shareware version of an avi program. Im sure this is a common enough program that there is already a solution to it. Good luck.

The 4GB file size limitation doesn't have anything to do with AVI files in particular but is purelly caused by Windows due to the FAT32 filesystem's inabillity to address pointers larger than 32bit.
Furthermore your video is not corrupted, your filesystem just has problems accessing it.

You can try opening it with VirtualDub, and you can also use the same program to chop the video into small chucks.

That was what the capture program I used said, but you're right it's a FAT32 disk and I should have thought of that in advance :/ Anyway, the file contained no headers, no nothing except the first frame header and the actual data, so i wrote this python script to extract the data, and here it is, should anyone need it:

import sys, os, struct

infile = open("f:\\kunst\\TimelyOrder\\TimeLapse.avi","rb")

while 1:
data = infile.read(4)
if data == "00db":
print data,
for i in range(0,4660):
data = infile.read(4)
data = infile.read(640*480*3)
print "Writing file %d" % (i)
outfile = open("frame%.4d.raw" % (i),"wb")
outfile.write(data)
outfile.close()
data = infile.read(4)
break

infile.close()

You might need to replace 00db in if data == "00db": with whatever header is used in the file. Also it only works for uncompressed AVI's with no sound... No time to make it userfriendly either, which also means it writes RAW files, sorry :)

Use at your own risk.

Oh, and thanks anyway :)
