Play video from Memory Stream

RE: Play video from Memory Stream
If User Account Control (UAC) is bugging you on windows 7 you can turn that off, easy google.

In your case you want to decompress the JPEG-stream, how where or when you do this is up to you. That ought to produce frames, probably in some buffer, then you read that framebuffer into a TVCLVideoBuffer and you make the VLGeneric-Gen/Filter send it to an ImageDisplay.

A VLGenericGen is probably the easiest, in the OnGenerate event you'd get something like:

------------------------
Read+decompress stream
Frame ready? No - return (do nothing)
Yes
|
TVLCVideoBuffer myBuffer(320,240,vfRGB24); // your frame width, height and videoformat
unsigned char *ptr=myBuffer.Write();
CopyMemory(ptr,(void *)JPegFrame,sizeof(JPegFrame)); // might need some different casting
OutBuffer=myBuffer;

Hope that gets you somewhere. Perhaps if you read the JPegFrame directly into myBuffer, if possible, it could even save some time.

Regards,
Dave
