Greetings all,

I am trying to store H264 stream (x264) and Speex stream in a MKV container.
MKV file created without any errors but when I play the file ,I cannot hear
the audio.

ffmpeg command even gives following information about the MKV file.

Input #0, matroska,webm, from 'c:\work\container-test\h264-speex-2.mkv':
    ENCODER         : Lavf54.2.100
  Duration: 00:03:20.63, start: 0.000000, bitrate: 256 kb/s
    Stream #0:0: Video: h264 (High), yuv420p, 352x288, SAR 1:1 DAR 11:9, 25
 25 tbr, 1k tbn, 50 tbc (default)
    Stream #0:1: Audio: speex ([9][161][0][0] / 0xA109), 32000 Hz, 2
channels, s
16 (default)
At least one output file must be specified

any tips?
