I don't know about that - there seems to be spare, but then I don't
really trust top.

The sample is quite short, so could be misleading, but looking at the
fps counter doing -

ffmpeg -i infile -an -sn -f null -

I get around 89 for your sample but 134 for the first bit of a similar
bitrate dvb sample I have.

I guess so if it decodes slower.
