  • How to downloaded embedded videos on Instagram that have multiple media network requests ? (ffmpeg / curl)

    21 octobre 2022, par flhu

    I was wondering whether it is still possible to download the stories on Instagram that have multiple media network requests nowadays. Previously, I could simply download them using the Firefox Media Page Info View. This is still possible for some content such as reels or by using ffmpeg / curl. I have posted the network behaviour when I load a story on Instagram and a Reel on Instagram. I could not figure out which of the network requests is the relevant one (assuming it is the request with the biggest size) and when downloading it, the VLC player does not recognise the video.

    


    Instagram Reel Network Request

    


    Instagram Stories Network Request

    


    When using the Firefox Media Page Info View, it is possible to download the content from the reel directly whereas the mp4 media file is greyed out.

    


    I tried to copy the URL from the network request using :

    


    ffmpeg -i  -c copy  


    


    Copying the corresponding curl request but also only works for the Reel where the HTTP response status codes is 206 (Reel) instead of 200 (Story).

    


  • FFmpeg : how to make video out of slides and audio

    17 juillet 2014, par Muhammad Umer

    So i have several images some png and some jpgs. And i have mp3 audio. I want to make a video file don’t care what format.

    So i want either :

    A video made up of xyz size meaning images are centered and cropped if they go beyond dimensions coupled with audio in mp3 format..

    or just one image centered or and cropped, still image, video with audio.

    I have tried copying and pasting things and even modifying them after reading documents but in the end i got a blank video with audio and huge file that took forever to complete.

    I have windows 7.

  • How can I use FFMPEG to fix a mpeg.ts file

    29 septembre 2017, par Tim McClure

    I have an mpegts file that has some minor quality issues. Can I use ffmpeg to create an mp4 file from it and the mp4 file plays fine - meaning the transmuxing to mp4 corrected the problem. I am trying to use ffmpeg to re-encode the mpegts file to another mpegts file and through the transmuxing have the video file fixed. The script I am using :

    ffmpeg -re -i 20170925T214300_S051-0001.ts -pix_fmt yuv420p -vcodec libx264 -r 25 -vf "scale=1024:576" -threads 0 -b:v: 2048k -bufsize 2244k -maxrate 2560k -profile:v baseline -g 50 -x264opts no-scenecut -x264opts force-cfr -an -f mpegts mcclure.ts

    Is what I am trying to do possible ?
