At least in this case, MPlayer seems to look at the codec tag rather
than the codec ID in order to determine the codec. Therefore, the
'fourcc' variable needs to be set to 'SVQ3' as well, which is later
copied to st->codec->codec_tag in matroskadec.c.

Subject: [PATCH] lavf/matroskadec: SMI to SVQ3
At least in this case, MPlayer seems to look at the codec tag rather
than the codec ID in order to determine the codec. Therefore, the
'fourcc' variable needs to be set to 'SVQ3' as well, which is later
