  • How to concatenate two or more videos with different width in FFMpeg and to maintain the same aspect ratio ?

    23 octobre 2019, par Aarwil

    I have five video parts to concat all. Each five videos are in the same width and height. The second part is the hstack of another 2 videos and the third part is the hstack and vstack of another 3 videos. While concat all the five video parts the aspect ratio is not maintaining in the final video. Since I am new to ffmpeg help me to sort out the problem

    I have tried with the command with filter complex and to reduce the size I used frame per second.

    "ffmpeg -i
    RM356ce8c15f47cb07b7af885fd718a39f/final/RM356ce8c15f47cb07b7af885fd718a39f.mp4 -vf scale=1280:480 -filter:v fps=fps=30 E :\test\routes\public\assets\downloads\RM356ce8c15f47cb07b7af885fd718a39f/final/RM356ce8c15f47cb07b7af885fd718a39f.mp4"

    Only ’-vf fps=fps=30’ read, ignoring remaining -vf options : Use ’,’ to separate filters

  • Concatenate chunk containg headers to another chunk in h264

    18 novembre 2014, par Ortixx

    I’m trying to extract thumbnails from a torrent stream by downloading the first couple of chunks to get the headers, another set of chunks from the middle and then concat them to have a single video file.

    For this I’m using nodejs but I’m having trouble with the concatenation part. Obviously the headers include the length of the video so if I simply concat another chunk to the end of the headers chunk, it won’t work.

    In other words, I have 2 chunks of a video file : The first one contains the headers and some material and the other one is fully composed of a video stream. I want to combine the two to form a single video file
    So my question is how can I make this work properly if at all ?
