Decoder sample
|
|
================================
|
|
|
|
Demonstrates how to implement a decoder in Media Foundation.
|
|
|
|
This sample implements a "fake" MPEG-1 decoder. The decoder does not
|
|
actually decode the video streqam. Instead, it simply scans the
|
|
bitstream for start codes. Then it finds the time code for each
|
|
payload and outputs a blank video frame with the time code.
|
|
|
|
NOTE: An earlier version of this sample was built into the MPEG1Source
|
|
sample.

Sample Language Implementations
|
|
===============================
|
|
C++
|
|
|
|
|
|
|
|
To build the sample using the command prompt:
|
|
=============================================
|
|
1. Open the Command Prompt window and navigate to the Transcode directory.
|
|
2. Type msbuild Decoder.sln.
|
|
|
|
|
|
To build the sample using Visual Studio (preferred method):
|
|
===========================================================
|
|
1. Open Windows Explorer and navigate to the Decoder directory.
|
|
2. Double-click the icon for the Decoder.sln file to open the file in Visual Studio.
|
|
3. In the Build menu, select Build Solution. The application will be built in the default \Debug or \Release directory.
|
|
|
|
|
|
To run the sample:
|
|
=================
|
|
|
|
This sample builds a DLL that must be registered.
|
|
|
|
To register the DLL:
|
|
|
|
1. Open an elevated command prompt.
|
|
2. Naviage to the Debug or Release directory.
|
|
3. Type "regsvr32 decoder.dll"
|
|
|
|
To unegister the DLL, type "regsvr32 /u decoder.dll"
|
|
|
|
|
|
You can use the decoder DLL with the MPEG1Source sample to play an
|
|
MPEG-1 video file.
