Play Video Directly from TMemoryStream - CapeCodGunny - 07-15-2014 07:51 AM
What are the steps needed to play a video using Delphi's TMemoryStream object instead of using the FileName property?
Thanks in advance.

I’d like to make the TMemoryStream the INPUT to TVLDSVideoPlayer.
There is no Filename.
The video is inside the database as a BLOB (BinaryLargeOBject).
The database outputs the video BLOB to a TMemoryStream.
The TMemoryStream becomes the INPUT to the TVLDSVideoPlayer.
How can this be done using Video Lab?

Hi! Instead of a TMemoryStream you may want to assign your blob to a TVLCVideoBuffer, the Read and Write methods might be of interest to you. The buffer can be fed to a VL(DS)ImageDisplay or using a VLGenericFilter to push it to a VideoPlayer. Hope that helps.

Dave

The buffer can be fed to a VL(DS)ImageDisplay or using a VLGenericFilter to push it to a VideoPlayer.I'm using Delphi XE4. Where can I find more information on the TVCLVideoBuffer?
