Cannot turn off (redirect) the logs properly about amazon-kinesis-video-streams-producer-sdk-cpp

@liuyangedward Thanks for your comments. The PIC (Platform Independent Codebase) layer has been designed with full portability in mind. The logging in your case gets defaulted to the system output - the logging is built using the macros which eventually result in a log API call with the right information level. This is the API that we are not exposing through the plumbing yet.

• We are working on exposing the logging API through the callbacks so the C++ layer can implement it using log4cpp.
• In the interim, you can modify the PlatformUtils.h to map LN:28
  #define __LOG(p1, p2, p3, ...) printf(p3, ##__VA_ARGS__) to a logger you need - in your case log4cpp call.

However, if you simply want to disable the metrics logging (which for the diagnostics purposes we print out on each key frame) you can modify the code in KinesisVideoStream.cpp LN 37 and simply remove this if block or put an unconditional false statement - something like this

if (FALSE && (frame.flags & FRAME_FLAG_KEY_FRAME) == FRAME_FLAG_KEY_FRAME) {
