  • 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.

  • .MKV to .MP4 choosing the audio and subtitles ?

    11 décembre 2016, par Leo Letto

    The following stream belongs to a .mkv file with dual audio ;

    Stream #0:0: Video: h264 (High), yuv420p(progressive), 1280x960 [SAR 1:1 DAR 4:3], 29.97 fps, 29.97 tbr, 1k tbn, 59.94 tbc (default)
    
Stream #0:1(eng): Audio: mp3, 48000 Hz, stereo, s16p, 256 kb/s (default)
    
Stream #0:2(por): Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s
    
Stream #0:3(eng): Subtitle: ass (default)

    Which ffmpeg command should I use to create an output with the language in Portuguese, already with the English subtitles ?

    I found some commands that can extract the language-based caption that I specify, but I didn’t find anything related to selecting the audio type.
