• FFmpeg error : ratecontrol_init : can't open stats file

  6 octobre 2017, par oldo.nicho

  I’ve setup an AWS EC2 instance running Ubuntu 14.04 and have installed FFmpeg so that I can compress and transcode video.

  I’m trying to do a two pass conversion with the following code :

  ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 1 -an -f mp4 ~/encoded/null

  and second pass :

  ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 2 -codec:a libfdk_aac -b:a 128k -f mp4 output-file.mp4

  However I get the following error :

• How to Compile FFmpeg with x264 and libfdk-aac for Android

  12 novembre 2016, par Codeveloper

  Everyone.

  Please understand that i use the wrong english.

  I want to make encoding application using FFmpeg.

  I was successfully building NDK with FFmpeg.

  However, to encode H.264 video made had failed( Codec not found.. ).

  I was learned that libx264 is need encode H.264 and libfdk-aac is need encode AAC.

  so I tried to build the libx264 and libfdk-aac, But does not easily cross-compile.

  Please tell me what I did wrong.

  I cannot understand that error !! I was confirmed that arm-linux-androideabi-gcc is found in the directory..

  I want to borrow you wisdom. Please tell me how to ’ffmpeg+x264+fdk-aac’ build for android.

  Thanks.. :-)
