• no c compiler found libx264 build [closed]

  24 août 2012, par kerim yucel

  I have been trying to build ffmpeg for Android and I have managed to do so by using roman10's tutorial.

  However, I needed x264 and I enabled libx264 in the configurations but it wasn't able to find the library. A quick internet search led me to the answer that I have to build x264 seperately and include it to ffmpeg config by editing ExternalLibs flags.

  Currently I am using this script to build x264. Everything is fine except the fact that the error saying "No working C compiler is found" pops up. I have updated and installed build-essential and my gcc version is up to date.

  Any help will be appreciated. Thanks a lot.

  P.S. I am using ndk 4 just to make everything compatible with the tutorial link given above. I am running Ubuntu with VirtualBox from Windows 7.

  Edit : I have been trying this tutorial as well, I am getting the same error along with unknown options error for each configuration options.

  Another edit :
  I have tried this code and obtained the following.

  echo 'int main() return 0 ;' > main.c && arm-eabi-gcc main.c || echo $ ?

  I have checked the flags as well, flags seem ok or I can't see the faulty line. Above you may find the build script I am using.

  Problem solved. It was just a mistake related to typos. It works well now.

• FFMPEG "Invalid data found when processing input" MP4 to MP3

  10 février 2014, par CubeBoy69

  I have a question. I'm converting videos from youtube to mp3. From 1000 files around 150 files this message is in the log.

  /home/desktop/www/tmp/314629.mp4 : Invalid data found when processing input

  The thing is it's only about 10% of the conversions. How can i solve this issue ?

  I'm converting like this

  ffmpeg -y -i /home/desktop/www/tmp/'.$random_flv_name.'.'.$download_format.' -vn -map_metadata -1 -ab 192k /home/desktop/www/audio/'.$yt_video_id.'/songtitle.mp3
