6.2 Enabling and using debug information

1) debugTraceLevel
2) lastNFramesToLog
This section describes the debug trace feature supported by codec and its
usage.
This section explains the approach and overall design that will be adopted
for enabling a trace from a video codec.
The primary use of Debug Trace Usage are:
details about the history of executing a particular instance of the codec
codec in case of a failure. A failure might even be a hang or crash but in
general can be defined as any unacceptable or erroneous behavior
Such a feature is targeted at providing more visibility into the operation of
the codec and thus easing and potentially accelerating the process of
debug.
To enable debug information, following two parameters are added to the
create time parameters
Hence the MPEG4 decoder create time parameters are modified as
typedef struct IMPEG4VDEC_Params
{
IVIDDEC3_Params viddec3Params;
XDAS_Int32 outloopDeBlocking;
XDAS_Int32 errorConcealmentEnable;
XDAS_Int32 sorensonSparkStream;
XDAS_UInt32 debugTraceLevel;
XDAS_UInt32 lastNFramesToLog;
