AVFormatContext (JavaCPP Presets for FFmpeg 6.1.1-1.5.10 API)

All Implemented Interfaces:

AutoCloseable
```
@Properties(inherit=avformat.class)
public class 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. Fields can be accessed through AVOptions (av_opt*), the name string used matches the associated command line parameter name and can be found in libavformat/options_table.h. The AVOption/command line parameter names differ in some cases from the C structure field names for historic reasons or brevity.

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
```
@Cast(value="int64_t")
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().

Flags must be cleared by the user once the event has been handled. - muxing: may be set by the user after avformat_write_header() to indicate a user-triggered event. The muxer will clear the flags for events it has handled in av_[interleaved]_write_frame().
