Making a simple WAV player

[jj2007]

little secret - that also works for VOB files   :P
although - i didn't have any luck with that player - lol

You mean the one I posted? I just tried my luck with Hutch's suggestion but no luck - even renaming to *.mpg just gave a message "damaged file". It opens fine in other players, though, meaning the codecs are there but mci is not able to find them.
For my own private *.avi files instead, renaming to *.mpg helps. If I use them as *.avi, there is a message "video not available", sound works (!), and the mouse is almost blocked.
The whole video business is very, very messy on Windows. I remember that frequently Windows doesn't know about its own formats. Greetings to Redmond :wink

i tried a variety of file types - mp4, m4v, flv, and so on - all of which i have codecs for
many of them would not play with your player
by renaming them to mpg, they did play
it did not work for vob's - although, i have had success with that when i did not have a full set of codecs

Dave I have a copy of Richard Hammond's BBC documentry of Evil Knievel in VOB format (last he ever gave) its an hour long and it plays perfectly on my Win 7 machine from that simple media player example of mine. I'm quite certain using the MPEGVideo type you can play most any media file if the correct codec is installed on a machine even VOB's.

yah - VOB files are containers for MPEG video information   :P

Dave,

Well to be honest about it I'm not all that savvy about all that media shit, I get an idea for an example I want to create and I start digging into Microsoft's SDK. That's how I derive every example I've created over all these years and at the same time having one hell of a lot of fun doing so. :bg

i hear ya, Bill
i am a novice, too - lol
i do have some interest - i'd like to learn more about it
for now, i am just trying to learn my way around the API   :P
