  • Keywords regression added; segmented recording removed

Is the issue reproducible with current FFmpeg git head? Do you believe that the information on https://ffmpeg.zeranoe.com/builds/ is unclear?

Is the issue only reproducible with dshow input or also with file (or lavfi) input?
Is the issue only reproducible with segment output or also with mp4 output?
Which commit introduced the regression?
