  • Cut the stream at specific clock time in FFMPEG

    14 juin 2017, par Fearhunter

    I use the following command from ffmpeg to cut my live stream from VLC :

    ffmpeg -i InputStreamURL -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls -hls_time 20 /var/www/html/ts/1.m3u8

    Now I want to cut the stream at a specific time like for example 09:00 am till 12:00 PM. I was reading about the segment muxer in the FFMPEG documentation. I read the following command :

    segment_atclocktime 1|0
    If set to "1" split at regular clock time intervals starting from 00:00 o’clock. The time value specified in segment_time is used for setting the length of the splitting interval.
    For example with segment_time set to "900" this makes it possible to create files at 12:00 o’clock, 12:15, 12:30, etc.

    Default value is "0".

    Is there a other command to specify a timestamp to record the stream ? This is my my interface I am gonna build :

    Live

    The scenario is :

    1 : enter stream URL
    2 : begin time = 15:00 pm
    3 : end time = 17:00 pm
    4 : pieces = 3

    Conclusion :

    15:00 - 17:00 = 2 hours
    2 hours * 3600 = 7200 seconds
    7200 / 3 = 2400 seconds for each sliced video

    How can I use segment_atclocktime for this scenario ?

  • Add sound effects at particular time in a Video file

    13 janvier 2017, par G Singh

    I have a video file and I need to add multiple audio effects to it at particular time.

    How can this be achieved ?

    Using FFMPEG only audio can be merged with video file but how to add a small audio effect at particular time.

    I tried the following way,

    ffmpeg.exe -i video.mp4 -i audio.mp3 -map 0:v -map 1:a -c copy -y output.mp4

    Is there any other open source or paid library to do this task ?

    Any kind of guidance will be appreciated.

    Thanks.
