• Seeking Ideas : How Can I Automatically Generate a TikTok Video from a Custom Song Using C# [closed]

  14 mai 2024, par Jamado

  Im creating a c# program which creates a video of the from a song and posts it on tiktok.

  


  Right now my program

  


  


  1. Uses spleeter to split the song into stems

     


  


  2. uses a script of GitHub to create waveform images of the stems

     


  


  


  I want my end video to look like this :

  


  https://vm.tiktok.com/ZMM7CDmUt/ - only one song will play per video

  


  https://vm.tiktok.com/ZMM7Xdw8b/

  


  https://vm.tiktok.com/ZMM7CcGtE/ - no webcam or that hitting animations

  


  basically I want the stems of the songs to be placed on top of a FL studio timeline, synced to the song, then I want to overlay a image on top of the video. and then to contribute for todays gen's 3 second attention span, add some audio virtualisations ontop of the fl studio recording (the music making app in the video) and a little shake to the image

  


  I've tinkered with ffmpeg before, and I reckon it could do the trick here. I'd use the waveform pictures and mix them with a pre-recorded FL Studio video using ffmpeg's filters, like VStack to stack images, Scroll to slide them around and Blend. And then tweak the overlay filter for that shake effect. Plus, I found out ffmpeg can whip up some basic audio visualizations, which is neat. (https://gist.github.com/Neurogami/aeed8693f7ac375d5e013b8432d04d3f)

  


  But my main issue with this approach is, how the waveform images will look weird/out of place ontop of the fl studio video, because FL studio has a really spesific "theme". I could manually create a template and then use some other library to merge the template image and the waveform image. But, it feels a bit janky and would probably be a hassle to set up and implement.

  


  So, I'm curious if you folks have any nifty libraries, GitHub gems, or ideas to help me nail this video ?

  


• Visual C++ linker can't resolve FFmpeg's external symbols

  25 février 2016, par JustPingo

  I’m making a C++ program and I want to use FFmpeg pre-built for x64, which is a C-compiled library.
  I’m using this code in order to include its header :

  extern "C" {
  
      #include "libavcodec/avcodec.h"
  
      #include "libavformat/avformat.h"
  
  
  
      #pragma comment (lib,"G:/Documents/ffmpeg/lib/avcodec.lib")
  
      #pragma comment (lib,"G:/Documents/ffmpeg/lib/avformat.lib")
  
  }

  I’m then calling the symbols like I would do for a normal function, for example with av_interleaved_write_frame(out->formatContext, &packet);

  However, when I try to compile it with Visual Studio 2015’s built-in C++ compiler, I get a lot of error like

  Error   LNK2019 unresolved external symbol _av_write_trailer referenced in function "void __cdecl closeArenaVideo(struct VideoOutput *)" (?closeArenaVideo@@YAXPAUVideoOutput@@@Z)  Sparta2 c:\Users\Théo\documents\visual studio 2015\Projects\Sparta2\Sparta2\video.obj   

  for basically any of the symbols I’m refering to.

  I tried to import everything in Visual Studio, to compile with command-line, to manually put FFmpeg’s libraries in the default libraries path, without success.

  Thank you in advance !

• mp4 wont play in Chrome 17, but plays in Safari, IE etc

  12 janvier 2013, par marca

  File is from a Nikon D3s (mov) converted with ffmpeg to mp4.
  Working without problems with all other files (avi, flv, mp4 etc)

  Please see file : http://shootitlive.s3.amazonaws.com/output.mp4
  (Same non working result in Chrome when served from diffrent hosts, and always works in Safari and with flash in Firefox, Chromium)

  /usr/local/bin/ffmpeg -i nonworking.MOV -acodec libfaac -ab 128k -vcodec libx264 -preset slow -crf 30 -threads 0 -s 768x576 -aspect 1.33333333333 -ar 48000 output.mp4

  Cant find anything strange with (but dont really know what to look for) :

  ffmpeg -v 5 -i filename -f null - 2>error.log`

  Any ideas ?
