• Cannot use FFmpeg in Xcode iOS Project (file .h not found)

  19 mars 2016, par BlackBox

  I followed almost step by step this guide.

  Almost because I downloaded, as a user suggested, ffmpeg ios library already built from here

  I followed from "Linking static libraries in Xcode" but I cannot import anyway the header files of ffmpeg. (So I got the .a files)

  For example

  #include "avformat.h"
  
  // or
  
  #import "libavformat/avformat.h"
  
  // or
  
  #import <libavformat></libavformat>avformat.h>

  Everything that I use does not work.

  I specify that those .a files are currently in my project directory, indeed, if I import the .a file, it doesn’t complain that it isn’t found, but when compiling, it complains about UTF-8 stuff because .a files are object libraries and cannot be imported that way.

  I put also the Header Search Paths for the project as it was suggested and the config.log file but nothing.

  Also I see libraries are missing from every project example of FFmpeg I was able to find on GitHub.

  Any ideas ?

• using FFmpeg converter from .mov format from portrait to landscape mode

  30 juin 2014, par Sohail Yasmin

  I have a critical problem. I am sharing the details with you.

  Problem : - I have a video file in .mov format, taken from the IPhone. This video is in portrait mode, I want to play this video on the webpage in landscape mode and vice versa.

  Please suggest me, should I convert my video from portrait to landscape mode using FFMPEG. Does FFMPEG provide this conversion feature ? If yes, Please send the exe and the command line for converting portrait video into landscape mode and vice versa.
  i am using these commands

  ffmpeg -i "Inputname.mov" -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k output.webm
  
  ffmpeg -i "Inputname.mov" -b 1500k -vcodec libx264 -vpre slow -vpre baseline -g 30 output.mp4
  
  
  
  ffmpeg -i "Inputname.mov" -b 1500k -vcodec libtheora -acodec libvorbis -ab 160000 -g 30 output.ogv

  any one can help to solve this issue

• Stream .mov to .flv with ffmpeg

  30 mars 2018, par Wise Colt

  When I run the following code, the flv file is being created. But it does not play. (File size 0 kB)

  var ffmpeg = require('fluent-ffmpeg');
  
  var fs = require('fs');
  
  
  
  var write = fs.createWriteStream('output.flv');
  
  var stream = fs.createReadStream('video.mov');
  
  
  
  ffmpeg(stream).format('flv').pipe(write, {end: true});

  It works when I change the code like this :

  var ffmpeg = require('fluent-ffmpeg');
  
  var fs = require('fs');
  
  
  
  var write = fs.createWriteStream('output.flv');
  
  
  
  ffmpeg('video.mov').format('flv').pipe(write, {end: true});

  I’m looking for a way to convert a .mov file to a .flv file using ffmpeg and createReadStream. Support.

  Notes : .mov files created with iPhone / iPad
