5105 AV输出FILTER, 解析源代码

/*****************************************************************************

File name  : testapp1.c

Description: Test application #1 (RODOW).This will perform the single AV decode
for feed from Packet Injector and satellite.The application supports normal mode
as well as debug mode.For Debug mode environment variable DEBUG_MODE needs to be
enabled.
