d29aaf12f4 avcodec/v4l2_m2m_enc: Avoid ;; 
Inside a function, the second ; in a double ;; is a null statement, but
outside of functions a double ;; is simply invalid C that compilers
happen to accept. v4l2_m2m_enc.c contained several ;; as a result of
macro-expansion. So change the underlying macro so that it doesn't
happen any longer.

This fixes warnings when compiling with -pedantic: "ISO C does not allow
extra ‘;’ outside of a function".

d09c35677d libavcodec/jpeg2000_parser: Add jpeg2000 parser 
I have attempted to write a JPEG2000 Parser. Have tested
by generating a file containing 14 frames, as mentioned
by Micheal. Have also tried testing with various packet
sizes by setting -frame_size option. Additionally,
fixed a few formatting issues as pointed out by Micheal.
