Would implementing the AVParser be useful and how simple a task would 
this be? Also I will take a look through the roundup to see what I can 
do there.

This is only fair and I understand, implementing the SVC decoder would 
be helpful to my current research but is not essential. If the mentors 
are not keen on the idea then I wouldn't mind picking another project of 
more relevance to FFMPEG.
