Alternatives don’t seem to cut it: func_pts doesn’t > print date and does not take basetime into account, func_strftime > doesn’t take basetime into account, and uses current time rather than > PTS. The I've been through a truckload of various gmtime/strftime() attempts, and I'm stymied in part because it appears that only flt provides the fractional seconds part that I want, ffmpeg appears to keep this down to millisecond accuracy, so by manipulating this we can get the output we want. The drawtext filter mentioned in @stib's answer is the key to insert the time. strftime has no way of printing milliseconds , datetime. ffmpeg strftime with milliseconds support. How do I make FFMPEG use localized strftime with drawtext? I have a big mp3 file, which I started recording at 17:24. What are the arguments for ffplay to output the duration/time-stamp of the current frame in millisecond resolution (dumping it to stderr or stdout, not embedding or overlaying it into the video)?. I tried something like this: ffmpeg -y -f alsa -acodec pcm_s16le -ac 1 -i hw:0,0,0 -acodec mp2 -ar. Command Line Tools Documentation. Definition at line 97 of file segment. The "normal" expansion mode provides the gmtime and localtime functions which both interpret strftime() type expressions. If it's after the input it will split from that exact position.
