The Smacker demuxer reads four consecutive 32bit values from the file

This is mainly about improving legibility of the code and getting rid of
overlong lines by using variables for st->codecpar instead of accessing
the codec parameters via st->codecpar->.
Also, some code has been moved to better fitting places.

Hello,
I had gone through ticket #7445 and it mentions about JPEG2000 parser.
What exactly does a parser do and how is it different from a decoder?
I am unable to understand the exact use case of a parser.

This is my WIP patch for GSoC and I worked on transformations involved in
encoding/decoding FLIF images. I have created a module under libavcodec and
as guided by my mentors I have tried to use pixel data from AVFrame structs.
