  • Looking for video libraries for editing video on windows/ios/azure service [on hold]

    17 juillet 2015, par sanyam

    Which library would be a good bet in terms of ...
    1. Richness in features (I want to create a video from short clips and images with effects and filters). Think auto videos created from Google Photos.
    2. Extensibility - I would prefer using similar tech on IOS and Windows apps. Might have to offload some processing to a web service on Azure (windows or linux).
    3. Programmability - An API is preferred over command line as it gives more flexibility and better error handling.

    Given all these options, what is my best bet ? I’ve only looked at ffmpeg till now, is there a better alternative ?

  • ffmpeg copy video in video with a specific time

    13 février 2017, par Alkl

    Im new in this topic (beginner) and Im german... So it’s a bit difficult to find the correct words...

    I’ll try to explain what I’ve done and what I want to do :

    1. Extract video area from the original video converted in PRORES codec :

      ffmpeg.exe -i test.mkv -ss 00:06:21.99 -t 00:00:01.94 -async 1 -strict -2 -c:v prores_ks -pix_fmt yuva444p10le -profile:v 4444 -bits_per_mb 8000 -s 1920x1080 cut_video.mov

    2. Edit the cut in After Effects

    3. Convert the PRORES in Matroska

      ffmpeg.exe -i "C :\Users\Alex\Desktop\ffmpeg-20170202-08b0981-win64-static\bin\cut_video\cut_video.mov" -vcodec ffv1 -acodec pcm_s16le temp.mkv

    4. Replace the video area in the originale video file at the time 00:06:21.99...

    I spend 4 hours for the two commands...
    So I despair at the fourth step. Is it possible ? Can you help me ?

    I made a picture, so you can understand better what Im doing... : http://i.imgur.com/HqlNxzW.jpg

  • How can I allow my users to combine audio and video tracks for downloading a youtube video ? [closed]

    1er décembre 2023, par Faizan Ahanger

    I have a website which, along a bunch a text, has a embedded youtube videos to play. I want to allow my users to also a be able to download those videos. There are too many videos there to store on my own server and I know that there are already website like y2mate.com and savefrom.net which do this.

    


    I used yt-dlp and using the --print-json parameter I can get the urls for downloading the files but the audio and video tracks are not combined for higher videos. Using ffmpeg seems to be the obvious solution but I don't understand where the videos should be combined. Should I download both needed tracks on my server and combine them before serving it to users ? This seems very inefficient as it take a lot of bandwidth for handling all download requests. There is also this library ffmpeg.wasm which according to them is "a pure WebAssembly / JavaScript port of FFmpeg enabling video & audio record, convert and stream right inside browsers !"

    


    This should work but it will require the users to download a 30MB webapp before they can download any video. This is also not very efficient, especially if they are downloading a video which is only a few MBs in size.

    


    Are these the only two options that I have or is there a better way to do this ?
