• Horizontally show two videos side by side and export to one video

  15 juin 2015, par Michael Liberman

  What I am trying to achieve :
  Programmatically (using some kind of script) combine two different videos to one video where the videos are shown side by side and sound from both videos is played simultaneously.

  I found at least two ways I could display two videos side by side but in each one I have a different problem that makes it difficult to complete the process :

  1. Avisyth and Avs2Avi :
     Avisyth really makes the process easy. With a simple Avisyth script like this you should be able to play two videos side by side :

     video1=AVISource("d:\file1.avi")<br />
video2=AVISource("d:\file2.avi")<br />
StackHorizontal(video1,video2)

     The creation of a new output file can be done with avs2avi.
     The problem here is that i am not able to play even one avi file with avisyth because I get "AviSource couldn’t locate a decompressor for fourcc xvid" message. I googled for the solutions to that problem but nothing helped. GSpot says that i have all the codecs needed and it seems I can not do anything. Because I can not get to running real videos, I dont know if the final video plays sounds from both videos. Avisyth installed correctly and I am able to run the following script StackHorizontal(version ,version).

  2. ffmpeg
     Works like a charm with two videos and the final file BUT i do not get the sounds from both videos but only the first one. I found out that the solution to add sound from the second video will be by using the libfaac in the command line, like that :
     

     ffmpeg.exe -i video1.mp4 -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; movie=video2.mp4, scale=iw/3:ih/3 [right]; [left][right] overlay=main_w/2:0 [out]" -c:a libfaac -b:v 768k Output.mp4

  but i always get an error that the encoder libfaac can not be found. I downloaded the libfaac.dll but still no result.

  Is there a solution to any of these problems ? Is there another way to programmatically make one video from two videos that are played side by side ? Thanks in advance.

• Server-side generated video with custom texture - Where to start ?

  12 février 2014, par opznhaarlems

  I am working on a project in which a user can upload an image and then after uploading the image, a video is generated and then displayed, containing the image which was uploaded as some sort of texture/mask. (Like they do in Elf Yourself).

  The original video should contain some sort of placeholder for the image to allow it to move around and be transformed on a matrix.

  I'm not really sure where to start off or how I should even call such a merging/blending process in the first place.

  A few requirements I've came up with so far :
  - The server runs PHP
  - I am able to use GD, Imagick and FFMPEG
