  • Add audios according to their timestamps with ffmpeg

    27 novembre 2020, par user14706760

    I tried this :

    


    ffmpeg -i first.mka -i second.mka -i third.mka -i fourth.mka
       -filter_complex
         "[1]adelay=184000|184000[b];
          [2]adelay=360000|360000[c];
          [3]adelay=962000|962000[d];
          [0][b][c][d]amix=4"
merged.mka


    


    But it turned out that amix scales each input's volume by 1/n where n = no. of active inputs. A normalization workaround is unacceptable in my case because I have hundreds of inputs. Is the any alternative way to add audio files according to their timestamps ?

    


  • FFprobe Check Stream Link

    13 novembre 2020, par Krasic

    I am trying to use FFprobe to test if a streaming link is active or not.

    



    For example this is a working streaming link :

    



    ffprobe -loglevel quiet -show_streams rtmp://Lrmh0w.cloud.influxis.com/yoy/_definst_/185


    



    I do get output which mean link is active.

    



    However, once I change link to something not work :

    



    ffprobe -loglevel quiet -show_streams rtmp://Lrmh0w.cloud.influxis.com/yoy/_definst_/18555555555


    



    The command keeps running in background with no result.

    



    Is there a way to bypass this, or is there any ffprobe timeout parameter ?
I couldn't find it from the official website documentation.

    


  • Place FFMPEG videos side by side, allign by frame number

    4 mars 2017, par Eduardo Perez

    So, I have 2 videos I would like to place side by side. I would like to align them by a frame number that I know for each video, assuming both videos have the same FPS. The frame numbers were found using the following command.

    ffmpeg -i "input.mp4" "output/%08d.jpg"

    So, let’s say I know the frame number I want to align for Video A is 126, while for Video B the frame number is 179. I want to align the videos side by side with these two frames lining up, so that the resulting video would be displaying Video A frame 126 at the same time as Video B frame 179. The resulting video also shouldn’t have any pieces from either video removed, so if one of the videos hasn’t started or isn’t finished, the resulting video keeps playing the active video, rather than having only the times when both videos are supposed to be playing. I also want to align both audio tracks as well.

    For this question I would prefer a single-command solution where I only need to input the videos and frame numbers I want to align, rather than having to do several steps manually.
