• FFMPEG images to video + overlay video

  7 novembre 2018, par AK47

  I am trying to make 15 second video where the background layer is a video made up of 2 images, the first line creates a 15 second video from 2 images.

  I chose a small framerate so it renders an mp4 quickly. I then overlay a webm video (which has transparency) over the images. The final video seems to keep the framerate of 2, but i would rather keep the 24 framerate of the webm video.

  Is this possible ? & is it also possible to turn the below into 1 statement.

  ffmpeg -loop 1 -framerate 2 -t 11 -i image1.png -loop 1 -framerate 2 -t 4 -i image2.png -filter_complex "[0][1]concat=n=2" backgroundvideo.mp4;
  
  ffmpeg -i backgroundvideo.mp4 -c:v libvpx-vp9 -i overlayvideo.webm -filter_complex overlay newvid.mp4

• Crop layout for Videos using touch for a Video Editor like Video Show or Filmora Go in android studio [closed]

  26 août 2020, par Rayhan Khan

  I am new to the android studio (Java) and video editing application. I am developing a video editor in android studio with FFMpeg Library.

  


  I want to create a crop layout with a rectangle layer on top of it to measure the details like :

  


  

crop video width : 900
crop video height : 500
left distance (x value) : 190
top distance (y value) : 110

                                    1280

• Stream video and commands on same connection or split connections ?

  10 mai 2013, par bizzehdee

  Background

  I am in the middle of writing a client/server app that i will install on every machine within my office (roughly 30 - 35 machines). I currently have the client connecting to the server and it has an ability to send mouse movement, mouse clicks, key strokes and execute certain commands. The next step is to stream back a video output of the screen, i am using the GDI method from Fastest method of screen capturing to capture the entire screen and will be using the x264 encoder to compress the frames and transmit them back to the client which will then decode and display the stream.

  Question

  is it best (by means of reducing lag, ensuring all commands are delivered as fast as possible and that streaming is as live as possible) that i transmit back along the same connection that i established for the commands, or, should i establish a separate connection on the same port, or on a different port to stream back the video ?

  P.S.

  i am aware that VNC, RD and other things such as TeamViewer already exist and already do this sort of thing, but none of these support all the requirements needed for what we need within this system.
