Gdi capture window title, then I close the window, ffmpeg send don't automatically stop. Version 2.3 will stop the capture.

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:

Replying to rogerdpack:

Yes. What I use is full version ( failing [2.4] and succeeding [2.3] ).

git bisect to determine the offending commit possible? Barring that you could use gdb on an ffmpeg_g.exe file and have it break on the failure line, then trace it out to see what's happening maybe?

no feedback from OP, recommend just closing this...
