 I use the command is:ffmpeg.exe -f gdigrab -framerate 24 -i title="" -f
 dshow -i audio=virtual-audio-capturer-sm -b 2000k -pix_fmt yuv420p -tune
 zerolatency -preset ultrafast -acodec libmp3lame -ab 64k -async 1 -ar
 22050 -f mpegts udp://234.6.8.135:9786?localaddr=127.0.0.1

 ----
 I found the problem in the file ffmpeg-2.4.2\libavdevice\gdigrab.c,at
 static int gdigrab_read_packet(AVFormatContext *s1, AVPacket *pkt);

 This function calls in ffmpeg-2.4.2\libavformat



 ----
 the dbgview is show error:
