Google was my friend, as I found a thread off messages with this subject
from back in August 2006. Glenn Anderson was describing what sounds like my
problem using the QTControl - after some number of files assigned to the
control, "bad things" happen - instability, crashes, access violation
messages, etc. I'm also using Delphi (Delphi 7 currently).
I tried the suggested remedy of making sure that I don't assign '' as an
empty string to the URL property. I put that in, but after a "while" (and
that's variable between machines), I get an access violation message
referring to Quicktime.qts. I'm going to try and dig through that today and
see if I can figure out what's actually being addressed - the message does
give a location within the file.
Is the QTControl stable enough for long-term use in a program? I've reverted
to using the plugin approach that I used with Quicktime 6. The quality is
worse - lots of tearing in video playback - but it runs. I use the SkyLight
library to access the Quicktime plugin - that works well.
However, people have seen the quality difference and would prefer to use the
newer version. But I need it to last more than a "short time". Some machines
play video "loops" for hours at trade shows, etc., and I need it to stay
running without access violation dialogs.
Thanks.
