org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.avformat.AVIOContext

All Implemented Interfaces:

AutoCloseable

Enclosing class:

avformat

public static class avformat.AVIOContext
extends Pointer

Bytestream IO Context. New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. sizeof(AVIOContext) must not be used outside libav*. \note None of the function pointers in AVIOContext should be called directly, they should only be set by the client application when implementing custom I/O. Normally these are set to the function pointers specified in avio_alloc_context()
