Can't capture video from dshow device. FFmpeg finish immediately resulting empty file I'm digitizing my old tape recordings from usb dongle. Everything been ok, I digitized several tapes, but I'm abandoned this project for a while and reinstalled windows. Keeping on secondary drive the same ffmpeg binaries and noted .txt file with recording options.

Now I tried to return to work, but in attempts to start recording ffmpeg just finishing immediately:

D:\video&gt;ffmpeg -f dshow -crossbar_video_input_pin_number 2 -video_size 720x576

I'm stuck and have no idea what can it be. Please help.

P.S. Sorry for my bad english.
Either remove the -copyts or switch -t 06:00 to -vframes 9000
