FFmpeg: AVFormatContext Struct Reference

void* AVFormatContext::priv_data

Format private data.

This is an AVOptions-enabled struct if and only if iformat/oformat.priv_class is not NULL.

unsigned int AVFormatContext::max_index_size

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. This can lead to slower or less accurate seeking (depends on demuxer). Demuxers for which a full in-memory index is mandatory will ignore this.

• demuxing: set by user

unsigned int AVFormatContext::nb_chapters

Number of chapters in AVChapter array.

When muxing, chapters are normally written in the file header, so nb_chapters should normally be initialized before write_header is called. 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.

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.

Muxing only, set by the caller before avformat_write_header().
