hi Philippe, Thank you for your reply. In some functions of MediaPlayerPrivateGStreamer.cpp, I can get output of printf. But when I add printf in some functions just like isAvailable, I cannot get anything output in all of the functions of MediaPlayerPrivateGStreamer.cpp. After many tests, I found only in* *MediaPlayerPrivateGStreamer.cpp the statement "printf()" not always work for me. I don't know why this happen and what's wrong with MediaPlayerPrivateGStreamer.cpp, but anyway, fflush seems to work for me now.
