Comment (by baituxp):

 I have tested 4 cases:

 1, encoding : x264, output : network,       memory leak: 60M/min,
 2, encoding : x264, output : null -,        memory leak: 60M/min,
 3, encoding : mpegvideo, output : network,  memory leak: 60M/min,
 4, encoding : mpegvideo, output : null - ,  memory leak: 27M/min,

 so, I think the memory leak exists in the input part of the ffmpeg.

 5.
 whats more, I guess the memory leak is caused by the exception handling of
 the input part .
 because we find that if the input video stream is "good"( "good" means no
 error messages output on the ffmpeg screen when ffmpeg is used to
 transcode a realtime ts stream), the memory does not leak, however, if the
 input video stream is "bad" ( "bad" means many error messages is printed
 on the screen ... ), the memory leaks very fast.
