Hi!

I have made a test application to transcode to vorbis format (webm
container).

So far, based on FFmpeg examples, things are somewhat working, and output
file plays properly, but sound in right channel is missing. I tried looking
at different possibilities, but so far could not find any answer.

For reference, this is the code I am using:

https://gist.github.com/anonymous/a3ac583194050081f5bc

Working under Windows 7, Zeranoe FFmpeg 32 bit build:

  libavutil      52. 62.100 / 52. 62.100
  libavcodec     55. 47.101 / 55. 47.101
  libavformat    55. 22.103 / 55. 22.103
  libavdevice    55.  5.102 / 55.  5.102
  libavfilter     4.  1.100 /  4.  1.100
  libswscale      2.  5.101 /  2.  5.101
  libswresample   0. 17.104 /  0. 17.104
  libpostproc    52.  3.100 / 52.  3.100

Input file "test.mp2", is attached as well.

Could anyone point to the place where I might be misunderstanding things?

Thanks in advance for your time...
