How Do I encode incoming Video using the MerlinIP SDK?
For simple record and playback the best examples in the SDK are CRecHD and CPlayHD. These are console (command line) applications. There are several C++ files used by CRecHD and CPlayHD that you don’t need to understand. CRecHD.cpp and CPlayHD.cpp should be all you need to familiarize yourself with. Those files are only about 20 lines of code each. A version of CPlayHD with a TCP socket interface is available and a version of CRecHD with TCP can be provided as well.
Lowest level encoding and capture control can be accomplished by programming of hardware register settings, using the MerlinIP board’s regmap documentation. For uncompressed capture and custom ingest applications, the urec.exe (simplerec) program may be used.
CRecHD work with the following codecs:
MPEG-2 (4:2:0 & 4:2:20
DVCpro100
H.264
For control of JPEG-2000 firmware based encoding and decoding, a different software interface is used.

More sophisticated control of the playout, including queuing and back-to-back playout, may be accomplished with the MerlinIP Playout dll program. This code is also available in the Skymicro SDK library; documentation may be found in the Skymicro SDK Dropbox folder.

How do I implement Genlock settings on the MerlinIP board?
The code that controls the BRec genlock dialog box is in fucntion videsethd.cpp in the BRecs source code. It controls every setting possible for genlock. Line 203 of videsethd.cpp shows exactly how to set the genlock to the analog source.
Run BRec and open the Video/Genlock Settings dialog box to see all the setting possible as far as genlocking goes. Then look in function vidsethd.cpp to see what code clicking a button in the dialog box causes to execute.
