• libx264 encoder error in ffmpeg android build

  26 décembre 2013, par kerim yucel

  Right now, I have a ffmeg build script which recognizes libx264 and compiles succesfully. I have also compiled x264 and obtained libx264.a library. Both ffmpeg and libx264 are built from source. I can build ffmpeg without libx264 succesfully as well. Below you may find my script which tries to build ffmpeg with libx264.

  #!/bin/bash

  Above script doesn’t give me libx264.a in ffmpeg output builds.Several other scenarios are as follows.
  If I enable x264 encoder, I get undefined reference errors to some variables in x264.c (in libavcodec).
  If I enable shared in ffmpeg configure, I get an error which says it can’t cd to my prefix directory (no permission issues by the way).

  I am using latest releases of ffmpeg and x264 (cloned the git today) and ndk 7. Ubuntu runs on VM, installed on Windows 7. For further details about my adventure of ffmpeg/x264 porting to Android, you may refer here.

  What should I do to use libx264 with ffmpeg ? I kept on trying this script with different configurations, removed all ffmpeg x264 folders and reinstalled them, but to no avail.

  Thanks a lot in advance.

  EDIT
  Below is my x264 build script. It builds fine, gives me the static library and the headers.

• FFMPEG and -crf on Android

  12 juin 2014, par mister-viper

  yesterday I managed to build a newer Version of FFMPEG for Android. I directly created a binary which allows me to invoke commands per commandline. I builded the Version using NDK r9d and the 4.8 linux_x86_x64 toolchain.

  After including everything in my Application my goal was to execute the command for which I did the whole effort.

  My goal is to run :

  ffmpeg -i example.mp4 -r 30 -vcodec libx264 -crf 0 output.mp4

  Running this command on the command line via python works absolutly fine. However, running this command on Android does not work.

  1) I get the error that I have to add

  -strict experimental

  After reading FFMPEG docu I found out, that this is due to the libx264. However, I do not understand why I have not to add this comment in the Python version.

  2) After adding the parameter above, I was able to convert the video. However, the result was horrible. The transcoded images were just some noisy blinking green stuff. Thus, I looked for the problem. The problem is the parameter :

  -crf 0

  Due to this parameter, the result was so horrible. However, if I change the parameter to

  -crf 1

  everything is working as expected. BUT : I really want a lossless encoding here. That was the reason for choosing -crf 0. Moreover, this parameter works fine in my python version.

  Can anybody explain to me :
  1) What are I’m doing wrong ?
  2) How can I use -crf 0 on Android ?

  Best regards,
  André

• Script timing with FFMPEG and PHP

  23 juin 2014, par egekhter

  I’m running into a very strange bug.

  Here’s my command console output :

  ffmpeg -i /transcodes/original/883_1000_1403436916_00001.MTS -y -vcodec libx264 -tune zerolatency -

  I’ve tried adding sleep(5) after :

          exec($cmd, $out, $ret);

  to give the script time to move the moov atom to the front before uploading the local file to s3 and then deleting the local file, but it is not 100% reliable.

  Any ideas ?
