 > Can you upload a sample?

 Unfortunately not without copyright infringement. What I am currently
 doing to circumvent this is
 {{{
         if(stream->codecpar->codec_id == AV_CODEC_ID_PCM_VIDC)
             stream->codecpar->codec_id = AV_CODEC_ID_PCM_U8;

 }}}

 The ARMovie header is:
 {{{
 ARMovie
 RPLFAKE movie

 No description
 124        video format
 320        x size in pixels
 120        y size in pixels
 24         bits per pixel RGB
 15         frames per second
 1          sound format
 44100      Hz Samples
 2          channel
 8          bits per sample (LINEAR UNSIGNED)
 1          frames per chunk
 2714       number of chunks
 180068     even chunk size
 180068     odd chunk size
 32409868   offset to chunk cat
 720        offset to sprite
 60         size of sprite
 0          (no keys)
 }}}

 Hope this helps.
