  • ffmpeg override the same file for every second of the video [on hold]

    5 février 2017, par Dorin Pleava

    I want to get one image for every 10 seconds from a livestream/video, but the image should have the same name, meaning I want to override it every cycle.

    This is my command :

    ffmpeg.exe -i http://iphone-streaming.ustream.tv/uhls/17074538/streams/live/iphone/playlist.m3u8 -bt 20M -s 480x300 -vf fps=1/10 -y photo.jpg

    This code works for one image but for the next I get this

    "Could not get frame filename number 2 from pattern ’photo.jpg’ (either set updatefirst or use a pattern like %03d within the filename pattern)
    av_interleaved_write_frame() : Invalid argument"

    If I replace photo.jpeg with photo%03d.jpg I get photo001.jpec, followed by photo002.jpeg, etc.

  • Issue regarding concatenate videos ffmpeg

    8 février 2021, par Mayank Thapliyal

    I want to concatenate 3 videos using ffmpeg. So I did a research on the net and got the required code. But later on I realized that it will not work as the attributes of the video are different and hence I will have to re-encode the videos

    


    So I got this on the internet :-

    


    ffmpeg -i 1.mp4-i 2.mp4 -i 3.mp4 -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4

    


    But when I ran it,it was SUPER slow. And ffmpeg recommended to add vsync 2 in the code. I added it in the following manner :-

    


    ffmpeg -i 1.mp4-i 2.mp4 -i 3.mp4 -vsync 2 -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4

    


    Now the video was processed on time and the result was also fine. But I don't know the meaning of the code. Will someone be kind enough to explain what exactly is happening ? (in this way I would be sure that the code will always work for me for all videos)

    


  • What do the special characters in an ffmpeg file output format mean ?

    3 février 2016, par Dan

    I need to process some videos with ffmpeg, and I found an example command that does almost everything I need it to :

    ffmpeg -i example.avi -vf fps=1/30 example_%03d.jpg

    I’ve figured out what all of this command does, but I’ve been unable to figure out the meaning of %03d in the output file format. What does %03d mean in a ffmpeg file output format mean ? What other special sequences are allowed in an ffmpeg output ?
