Its fractional part is the time in microseconds, which is what you want. 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)?. In conjunction with stream copying (-c copy), ffmpeg will seek to the closest seek point before the position (e. nginx-rtmp-vod-ffmpeg Public Simple RTMP docker server that stream /dev/video0 InSoundz/nginx-rtmp-vod-ffmpeg’s past year of commit activity.

As ack-inc indicated, it makes a difference whether -ss is placed before (input option) or behind (output option) the -i. ffmpeg interprets the input as local time, then converts it to and stores it as UTC. * -to: The position of where the command is going to cut to. Examining AVOptions. mmm format. strftime() that will return you the milliseconds. Additionally, it looks like you can use the strftime() function to format the timespan calculation in order to render the time however makes you happy. I am using ffmpeg to record a camera stream using rtsp protocol. strftime option relies on system's implementation of a C function with the same name. (dot) you have the simple options from other answers combining %(asctime)s, and %(msecs)03d like so (using logging. Improve this question. As far as I know ffmpeg's strftime template does not support creating files with millisecond resolution. increment_tc. The "milli" means "thousandths", as in 3 digits. I suggest to number the frames sequentially and maybe overlay the time on the video, or just below it. Such structs in FFmpeg are e. strftime() on the other hand has %f. See also ctime(3). 82. Note that. (so ffmpeg strftime with milliseconds support. vg. 17. de: State: New: Headers: show Afaict, there is no way to get the current time with a higher precision than seconds in POSIX on which FFmpeg depends.

The default is 15000 (15s). the closest keyframe), if used as an input option. If it gets to a certain point then I want to seek to a later point in the video. strftime, and time. For the log output, you can call av_log_set_callback () to provide a custom callback which includes a more verbose date/time that includes millisecond resolution.
