  • Fast seeking ffmpeg multiple times for screenshots

    14 septembre 2021, par user3786834

    I have come across https://askubuntu.com/questions/377579/ffmpeg-output-screenshot-gallery/377630#377630, it's perfect. That has done exactly what I wanted.

    



    However, I'm using remote URLs to generate the screenshot timeline. I do know it's possible to fast seek with remote files using https://trac.ffmpeg.org/wiki/Seeking%20with%20FFmpeg (using -ss before the -i) but this only runs the once.

    



    I'm looking for a way to use the

    



    ./ffmpeg -i input -vf "select=gt(scene\,0.4),scale=160:-1,tile,scale=600:-1" \
-frames:v 1 -qscale:v 3 preview.jpg


    



    command but using the fast seek method as it's currently very slow when used with a remote file. I use PHP but I am aware that a C method exists by using av_seek_frame, I barely know C so I'm unable to implement this into a PHP script I'm writing. So hopefully, it is possible to do this directly with ffmpeg in the PHP system() function.

    



    Currently, I run seperate ffmpeg commands (with the -ss method) and then combine the screenshots together in PHP. However, with this method it will be refetching the metadata each time and a more optimized method would be to have it all happen in the same command line because I want to reduce the amount of requests made to the remote url so I can run more scripts in sequence with each other.

    



    Thank you for your help.

  • why doesn't ffmpeg name files with sequence after using strftime ?

    5 décembre 2016, par user2030856

    I would like to know why ffmpeg stops naming my files with a sequence number (%03d) when using -strftime 1 ?

    for example : filename_%Y-%m-%d_%03d.ts

    I need to get filename_YEAR_MONTH_DAY_SEQUENCE#.ts
