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

[Andrey Filippov]

Sebastian,

It is probably limitation of the directory size, camera can not handle that
many files.

Bader,

quicktime is not a right tool to split MOV file, we use simple PHP scripts
to split image sequences, including Eyesis camera. Did you try it?
