• 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

• 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 ?

• Nginx video streaming - ffmpeg convert to flv, but requsted is mp4

  18 juin 2012, par abrahab

  I am converting videos from different sources with ffmpeg to mp4 with libx264 codec.
  The following command (simplified) :
  ffmpeg -i 1.mp4 -y -f mp4 -vcodec libx264 -crf 28 -threads 2 -strict experimental -acodec aac -ab 56k -ar 44100 -ac 2 temp.mp4

  Then, I can not stream the output file (500 Internal Server Error) with nginx mp4-streaming solution (aka http pseudo streaming). My system administrator found, that if rename file to flv it stream well, so, seems the output file is not mp4, but flv ? Why ? How to correctly convert ? Or, please, suggest how to stream video properly ? I think that mp4 is much better then flv... therefore I choose mp4.

  In other words, the problem is to stream output file like mp4.

  ps i also need to be sure that this video will always work at ipad after convertation. thanks and sorry for my bad english.

  EDIT : I found that if convert video with the same string but without -vcodec libx264 - nginx can serve the output .mp4 file well. where may be the problem ?
