• static ffmpeg build error : dyld library not loaded libx264.164.dylib

  17 mars 2023, par Martin

  I am trying to build ffmpeg on my macos 10.13 computer. When I run my buildscript.sh file, I get an ffmpeg and ffprobe output, but when I try to use that final build ffmpeg file on a different macbook, I get an error saying the x264 library was not found :

  


  //running ffmpeg on macbook 2:
martins-iMac:Downloads martin$ chmod +x ffmpeg 

martins-iMac:Downloads martin$ ./ffmpeg 

dyld: Library not loaded: /usr/local/opt/x264/lib/libx264.164.dylib

  Referenced from: /Users/martin/Downloads/./ffmpeg

  Reason: image not found

Abort trap: 6


  


  When I build ffmpeg using my script on macbook1, I made sure to install x64 with brew install x264, but like the error says above, I think this x264 library is not being incuded in my static ffmpeg build, is there any flag im missing in my ./configure part, or do I need to specify the filepath for my local libx264 install location as a part of my build script ?

  


  buildscript.sh :

• FFMPeg : how to establish a mms connection on the iPhone ?

  29 décembre 2011, par Winston

  I'd like to use ffmpeg to connect to a live stream, using the mms:// protocol and afterwards decode the WMA file to play on the iPhone.

  Which one of the following function should I use ? And how do I use it ?

  1) MMSContext http://ffmpeg.org/doxygen/trunk/structMMSContext.html

  or

  2) URLContext http://ffmpeg.org/doxygen/trunk/structURLContext.html

• FFMPEG : MP4 videos are not palying properly in iPhone, iPod, iPad

  25 mai 2012, par Shakti Singh

  I am converting videos from m4v, flv to MP4 for iPhone, iPod, iPad.

  I am using the below command to convert these videos

  ffmpeg -y -i video_1336500693.m4v -vcodec libx264 -vpre slow -vpre
  ipod640 -b 250k -bt 50k -acodec libfaac -ab 56k -ac 2 -s 480x320
  video_1336500693.mp4

  The video part of this mp4 file is working fine but the audio is not working properly. I am using HTML5 for this.

  The audio works for first 8-10 seconds but after that audio does not work and the strange thing is if I jump to forward or backward the audio works.

  Can anyone suggest what's going wrong ?

  Thanks
