    Fixes compilation of libavformat when librtmp is enabled but all the
    
relevant protocols are disabled.

  • FFMPEG zoompan only applies and shows 3 images out of the many

    26 mai 2018, par Sanjyot Shah

    I am trying to generate a video from images using FFMPEG 4.0 windows built on AWS windows instance using PHP.

    $command2="ffmpeg -r 1/5 -i https://<path>/$images%d.jpg -c:v libx264 -r 5  -t $total_video_time -y  ".trim($video_name)." -i http://<path>/$audio ";
    
</path></path>

    The above generates the correct video output with all the input images (50 in this case) but without the zoompan effect on the images.

    Now I try to add the zoompan effect for the images using -

    $command2="ffmpeg -r 1/5 -i https://<path>/$images%d.jpg  -filter_complex zoompan=z='zoom+0.002':d=25*4:s=1280x800 -pix_fmt yuv420p  -c:v libx264 -r 5  -t $total_video_time -y  ".trim($video_name)." -i http://<path>/$audio ";
    
</path></path>

    This will only pick up the first 3 images and apply the zoompan to the first two images or so.

    Can you please help me with this issue ? Any inputs, pointers are welcome too.
