avformat.AVFormatContext (JavaCPP Presets for FFmpeg 2.7.1-1.0 API)

java.lang.Object
- org.bytedeco.javacpp.Pointer
- - org.bytedeco.javacpp.avformat.AVFormatContext

Enclosing class:

avformat
```
public static class avformat.AVFormatContext
extends Pointer
```
Format I/O 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(AVFormatContext) must not be used outside libav*, use avformat_alloc_context() to create an AVFormatContext.

```
    Maximum amount of memory in bytes to use for the index of each stream. If the index exceeds this size, entries will be discarded as needed to maintain a smaller size.

Some muxers (e.g. mov and mkv) can also write chapters in the trailer. To write chapters in the trailer, nb_chapters must be zero when write_header is called and non-zero when write_trailer is called. - muxing: set by user - demuxing: set by libavformat

  - max_interleave_delta
```
public long max_interleave_delta()
```
    Maximum buffering duration for interleaving. To ensure all the streams are interleaved correctly, av_interleaved_write_frame() will wait until it has at least one packet for each stream before actually writing any packets to the output file. When some streams are "sparse" (i.e. there are large gaps between successive packets), this can result in excessive buffering. This field specifies the maximum difference between the timestamps of the first and the last packet in the muxing queue, above which libavformat will output a packet regardless of whether it has queued a packet for all the streams. Muxing only, set by the caller before avformat_write_header().
