  • Use FFmpeg to compare the same videos with different lenght

    5 mai 2016, par user3043703

    I have two videos taken from the same multimedia file, with identical video codec, bitrate, width x height, audio codec, etc... It would be possible, for example, to see if one video includes the second and to get the time where the second video starts to differentiate from the first ? I think that this job should be done by FFmpeg and the right process would be to compare just video or audio frames. I know some basic commands but really cannot understand how to perform this kind of comparison.

  • Quickly split videos into parts with ffmpeg

    20 avril 2021, par RewossKy

    I'm doing splitting on FFMPEG. I divide 1.5 hour videos into 30 minutes. I have two ways of partitioning, the first is the method of rendering by recodecing on the top, I do not have any problem in this, but the time is quite long despite the GTX 1660s graphics card and the ryzen5 3500x processor.

    


    At the bottom, the time is short, but the first 3-4 seconds of the second part videos are frozen. Sometimes this causes problems like not reading in video editing programs.

    


    With recodec (slow, no problem)
ffmpeg -i 1.mp4 -vcodec libx264 -crf 30 -ss 00:00:00 -t 00:29:30 s1.mp4
ffmpeg -i 1.mp4 -vcodec libx264 -crf 30 -ss 00:29:31 -t 00:29:30 s2.mp4
ffmpeg -i 1.mp4 -vcodec libx264 -crf 30 -ss 00:59:01 -t 00:29:30 s3.mp4
ffmpeg -i 1.mp4 -vcodec libx264 -crf 30 -ss 01:28:30 -t 00:29:30 s4.mp4

    


    Without recodec (fast but have problem sometimes)
ffmpeg -i 1.mp4 -vcodec copy -ss 00:00:00 -t 00:29:30 s1.mp4
ffmpeg -i 1.mp4 -vcodec copy -ss 00:29:31 -t 00:29:30 s2.mp4
ffmpeg -i 1.mp4 -vcodec copy -ss 00:59:01 -t 00:29:30 s3.mp4
ffmpeg -i 1.mp4 -vcodec copy -ss 01:28:30 -t 00:29:30 s4.mp4

    


  • Playing Several Videos in a Row From a Browser

    2 août 2014, par user18490

    It’s simple to play 1 video (using HTML5), but my question is, can you play 2 or more videos in a row.

    Basically I’d like to let the user select as many clips as he/she wants, and let him/her play them in the browser (or potentially an external player such as FFplay, but the browser is my goal for now). It’s similar to the concept of playlist in Youtube, ... there should be no cut between two consecutive clips (which is the case right now with playlist in Youtube).

    Is that possible with existing API/tools/techniques ?
