[Elphel-support] Odd Bug: Jpeg Sequence stops at 1909 frames on every attempt

Thu Mar 17 10:53:11 PDT 2011

Dear Bader,

Yes, we are not able to support programs on MS Windows that we do not use
ourselves, but it should be rather easy to do if you can find help from
somebody who can program for that system

The PHP script we use ourselves is here:
http://elphel.git.sourceforge.net/git/gitweb.cgi?p=elphel/miscellaneous;a=blob;f=split_mov.php(with
line number) or
http://elphel.git.sourceforge.net/git/gitweb.cgi?p=elphel/miscellaneous;a=blob_plain;f=split_mov.php-
for downloa
