The patch was affecting the 'recording time' (-t) functionality. Sorry for not conducting fate tests before submitting the patch. I have updated the patch and have run the fate tests. Apart from the issue fix updates, I have modified the commit name and message for better clarity. Please find the revised version here https://patchwork.ffmpeg.org/patch/8814/ .
