    Hi I am trying to compile ffmpeg but this error shows :

If you think configure made a mistake, make sure you are using the latest
    
version from Git.  If the latest version fails, report the problem to the
    
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
    
Include the log file "config.log" produced by configure as this will help
    
solving the problem.

  • Avconv : Select german stream not highest quality one

    15 novembre 2013, par mblaettermann

    I am converting some input stream from my DVB S2 Card to RTMP.

    Everything works fine after switching to recent avconv and x264 :)

    The only thing I couldn't find out is, how do I select the right audio stream ?

    The source sometimes has up to 6 audio tracks. Avconv automatically chooses the one with the highest bitrate. However I want to select the "ger" one :

    Here are the streams of ARTE german/french TV Channel for example :

    Input #0, mpegts, from 'http://192.168.1.50:9981/stream/channelid/1035':
    
  Duration: N/A, start: 19083.694722, bitrate: 15576 kb/s
    
  Program 1
    
    Stream #0.0[0xa8], 127, 1/90000: Video: mpeg2video (Main), yuv420p, 544x576 [PAR 32:17 DAR 16:9], 1/50, 15000 kb/s, 25 fps, 90k tb50 tbc
    
    Stream #0.1[0x70](fre), 204, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 192 kb/s
    
    Stream #0.2[0x71](ger), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
    
    Stream #0.3[0x72](eng), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
    
    Stream #0.4[0x73](qaa), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
    
  No Program
    
    Stream #0.5[0x3b], 126, 1/90000: Audio: mp1, 0 channels, s16p

    libav Docs are really not that helpful. Who does now the right syntax ?

    EDIT : I found the -map option : http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20use%20-map%20option But it is not possible to map by name ? Only by index ?

    Maybe I need to use avprobe then, to find the corrent stream index for "ger".
