Method Summary

int	close(AVFormatLibrary.URLContext h)
int	open(AVFormatLibrary.URLContext h, java.lang.String filename, int flags) Flags may be a combination of: AVFormatLibrary.URL_RDONLY, AVFormatLibrary.URL_WRONLY, AVFormatLibrary.URL_RDWR.
int	read(AVFormatLibrary.URLContext h, com.sun.jna.Pointer buf, int size)
long	seek(AVFormatLibrary.URLContext h, long pos, int whence) Implementations need to be very careful about returning -1.

Method Detail

open

int open(AVFormatLibrary.URLContext h,
         java.lang.String filename,
         int flags)

Flags may be a combination of: AVFormatLibrary.URL_RDONLY, AVFormatLibrary.URL_WRONLY, AVFormatLibrary.URL_RDWR.

read

int read(AVFormatLibrary.URLContext h,
         com.sun.jna.Pointer buf,
         int size)

write

int write(AVFormatLibrary.URLContext h,
          com.sun.jna.Pointer buf,
          int size)

seek

long seek(AVFormatLibrary.URLContext h,
          long pos,
          int whence)

Implementations need to be very careful about returning -1. Basically, they should support full seek capability, or not at all, because much code in ffmpeg never checks the return value of a seek.

close

int close(AVFormatLibrary.URLContext h)
