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.

| int64_t AVFormatContext::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.

| int(* AVFormatContext::io_open) (struct AVFormatContext *s, AVIOContext **pb, const char *url, int flags, AVDictionary **options) |
A callback for opening new IO streams.
Whenever a muxer or a demuxer needs to open an IO stream (typically from avformat_open_input() for demuxers, but for certain formats can happen at other times as well), it will call this callback to obtain an IO context.
| s | the format context |
| pb | on success, the newly opened IO context should be returned here |
| url | the url to open |
| flags | a combination of AVIO_FLAG_* |
| options | a dictionary of additional options, with the same semantics as in avio_open2() |
