finish

public void finish()
            throws IOException

Description copied from interface: Muxer

Finalize writing this file. This function needs to be called at the end of the muxing session since some muxers use global headers and those can only be known at the end of the coding session. After calling this method no further muxing is possible with this muxer though this check might not be enforced by individual muxers. Calling any muxer methods after this function returns yields an undefined behavior.

Specified by:

finish in interface Muxer

Throws:

IOException
