#MPEG Problem
2 messages in this thread
Hi,
I was wondering about MPEG playback cards and their drivers. I have a need to
be able to pull up an MPEG file onto a blue background. The frame of the
video I'm seeking to is also blue.
I'm doing this with a MCI string commands using
OPEN
LOAD
SEEK
WINDOW STATE SHOW
Normally, with .AVI files, the file loads, opens, seeks to a frame and then is
put in a window on the screen, paused.
When I try this with the RealMagic MPEG card, I always get a black flash on
opening the file. I still show a paused frame in the .MPG file, except that I
always get a black flash, then the frame in question.
I heard this was the driver's fault, not MPEG as a platform. Is there anyone
who has any info on this? Maybe a MPEG card with a good driver?
Thanks,
John
Hi Jon,
I think the problem is in the MCI driver of the RellMagic. Video for Windows
uses the AVIVideo MCI-command set, the ReelMagic uses neither the AVIVideo nor
the MPEG MCI-command set. It uses OVERLAY MCI-command set. There is a little
bit difference between these command sets. I have had a similar problem, now it
works, I think you should read the specs and you will see what's necessary.
Regards,
Martin
