  • ffmpeg - how can I get a specific channel using channel masks (e.g. : get only surround left channel)

    26 novembre 2013, par awfulcode

    I'm trying to build a mixer that allows users to toggle specific channels on and off. I know that different codecs encode those channels in different orders (it's not as simple as getting channel #3 as the center channel every time), so the challenge is to properly identify the channel position in surround audio tracks.

    ffmpeg does list the in the beginning of libavutil/channel_layout.h :

    #define AV_CH_FRONT_LEFT             0x00000001
    
#define AV_CH_FRONT_RIGHT            0x00000002
    
#define AV_CH_FRONT_CENTER           0x00000004
    
#define AV_CH_LOW_FREQUENCY          0x00000008
    
#define AV_CH_BACK_LEFT              0x00000010
    
#define AV_CH_BACK_RIGHT             0x00000020
    
#define AV_CH_FRONT_LEFT_OF_CENTER   0x00000040
    
#define AV_CH_FRONT_RIGHT_OF_CENTER  0x00000080
    
#define AV_CH_BACK_CENTER            0x00000100
    
#define AV_CH_SIDE_LEFT              0x00000200
    
#define AV_CH_SIDE_RIGHT             0x00000400
    
#define AV_CH_TOP_CENTER             0x00000800
    
#define AV_CH_TOP_FRONT_LEFT         0x00001000
    
#define AV_CH_TOP_FRONT_CENTER       0x00002000
    
#define AV_CH_TOP_FRONT_RIGHT        0x00004000
    
#define AV_CH_TOP_BACK_LEFT          0x00008000
    
#define AV_CH_TOP_BACK_CENTER        0x00010000
    
#define AV_CH_TOP_BACK_RIGHT         0x00020000
    
#define AV_CH_STEREO_LEFT            0x20000000  ///< Stereo downmix.
    
#define AV_CH_STEREO_RIGHT           0x40000000  ///< See AV_CH_STEREO_LEFT.
    
#define AV_CH_WIDE_LEFT              0x0000000080000000ULL
    
#define AV_CH_WIDE_RIGHT             0x0000000100000000ULL
    
#define AV_CH_SURROUND_DIRECT_LEFT   0x0000000200000000ULL
    
#define AV_CH_SURROUND_DIRECT_RIGHT  0x0000000400000000ULL
    
#define AV_CH_LOW_FREQUENCY_2        0x0000000800000000ULL

    But looking over the header files and whatever little documentation about ffmpeg I couldn't find anything that tells me how to assign a specific channel position (or mask, as it's described in the header file) to a specific bus in a mixer audio unit.

    Do you know how to do that ? Please let me know if you want to look at the code I'm using right now.

    And as always, thank you so much.

  • ffmpeg get the audio stream from mp4 and send it to speech recognition

    12 juillet 2013, par user1896859

    I have few .mp4 video files in which at the start of each video file there is a word, I want to load these files get the audio check what is the spoken word and rename the file accordingly.

    Currently what i am doing is, converting all the mp4 files to wav and then sending the to speech recognition and then doing the renaming stuff.

    Is there a way to cut short the "converting to wav" part out and directly send the mp4 audio stream to speech recognition ??

    Thanks,
