  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

  • Create animation video or applying different effect on video from set of images [on hold]

    9 janvier 2016, par Mehul Dudhat

    I tried with FFmpeg but it’s not showing any effect with created video.

    I tried below command with FFmpeg lib :

    ffmpeg -f image2 -r 1/5 -i /&lt;<dir path="path">>/img/img%d.jpg -vcodec libx264 /&lt;<dir path="path">>/output_video.mp4
    
</dir></dir>

    The image generated video :

    Is there any other library available to add effect or animation on video during the creation from set of images ?

    I would like to give this type of animation or effect :

  • FFMpeg : how to merge video and audio and tail align video to audio length ?

    28 septembre 2021, par Bobby

    I have a video file and an audio file to merge together. Audio duration is shorter than video. I want to align them at tail and cut off the head part of the video.

    &#xA;

    Graph illustration :

    &#xA;

    [xxxx------] video&#xA;    [------] audio&#xA;    [======] merged&#xA;

    &#xA;

    Where "x" parts of the video is removed.

    &#xA;

    The duration of the video/audio is unknown but the audio duration is guaranteed to be shorter than video. The reason of it being unknown is because I'm generating video dynamically and pipe to FFmpeg, so it is not possible to know the duration beforehand.

  • Cutting HEVC video results in parts stating with no video (black image) but correct audio for a few seconds

    8 juin 2020, par Oliver

    i have large HEVC video files and want to cut out parts of them. I use ffmpeg for that with the following command :

    &#xA;&#xA;

    ffmpeg -i input.mp4 -ss 01:18:47.040 -c:v copy -c:a copy -to 01:18:42.640 output.mp4&#xA;

    &#xA;&#xA;

    i know that there can be problems when copy is used and no re-encoding, that is why i checked before that the frames specified in the -ss and -to parameters where keyframes (i-frames).

    &#xA;&#xA;

    So iam expecting to get a clean cut at the beginning and at the end. But what i get is 10 seconds of black image with normal audio in the beginning until the video starts. To make this clear : 10 seconds of video are missing in the beginning but the audio is fine.

    &#xA;&#xA;

    Btw : when moving the -ss part before the -i there seem to be no problems with the video (at least in the beginning). I know about the differences of putting -ss before and after the -i, but i also know, that using -ss after the -i should be slower (and was more accurate in the past) but should not make any differences in the final result. That is why I am so irritated.
