That seems very > unfair to the API user.
libavformat/isom.h is needed only for MOVElst, which is the following:
typedef struct MOVElst {
int64_t duration;
int64_t time;
float rate;
} MOVElst;
About the bytestream, that's kind of the same issue you will have for parsing
kind of any bytestream, I don't think it is really unfair since most multimedia
app will probably already have that.
