  • iPhone video PHP upload. Windows to HTML5 tag

    21 août 2012, par zeshin

    As those of you with an iPhone know, the iCloud uploads all pictures and videos taken on the iPhone to the cloud and, thereafter, your home PC.

    I am uploading videos to my web page through a PHP function, which are then displayed as embedded HTML5 videos with the tag. The problem I am running into is that videos taken on the iPhone in portrait are showing up on both my PC and website in landscape view.

    Due to the fact that uploads come from multiple sources, I need a sever-side solution to recognize the orientation of the video and rotate it as needed.

    Does anyone know of a way to accomplish this without using additional plugins such as ffmpeg ?

  • Generate video from images with ken burns effect using ffmpeg

    1er janvier 2014, par user1615796

    I am trying to generate video from images.

    The following code generates the video, 1 frames per 3 seconds.

         exec("ffmpeg -f image2 -r 1/3 -loop_input -shortest -y  -i tmp/image%3d.jpg -i tmp/ag1.mp3 -target ntsc-dvd -s 1280x720 tmp/video.mwv");

    I want to apply ken burns effect to it, I have searched a lot but couldn't find any solution.

    Can anybody help me out ? If can provide any code snippet, will be really appreciated.

  • ffmpeg Too many bits per frame requested

    18 novembre 2016, par GRaecuS

    I am using ffmpeg to convert videos to mp4 format. Everything works fine except with MOV format.

    The command I use for everything is :

    ffmpeg -i input.mov -strict experimental -sameq -s vga -aspect 1.7777 -vcodec libx264 -preset fast -crf 22 -y output.mp4

    but the output I keep getting is :

Stream mapping:
    
  Stream #0:0 -> #0:0 (mpeg4 -> libx264)
    
  Stream #0:1 -> #0:1 (pcm_mulaw -> aac)
    
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    It seems the problem is with audio’s bit per frame.
    Which might be the right solution ?
