Callback used by devices to communicate with application.
typedef struct AVFormatContext AVFormatContext |
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.
typedef struct AVFormatInternal AVFormatInternal |
typedef struct AVIndexEntry AVIndexEntry |

typedef struct AVProbeData AVProbeData |
This structure contains the data a format has to probe a file.
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(AVProgram) must not be used outside libav*.
Stream structure. 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(AVStream) must not be used outside libav*.
typedef struct AVStreamInternal AVStreamInternal |

int av_append_packet | ( | AVIOContext * | s, |
AVPacket * | pkt, | ||
int | size | ||
) |
Read data and append it to the current content of the AVPacket. If pkt->size is 0 this is identical to av_get_packet. Note that this uses av_grow_packet and thus involves a realloc which is inefficient. Thus this function should only be used when there is no reasonable way to know (an upper bound of) the final size.

pkt | packet |
size | amount of data to read |
enum AVDurationEstimationMethod av_fmt_ctx_get_duration_estimation_method | ( | const AVFormatContext * | ctx | ) |

int avformat_alloc_output_context2 | ( | AVFormatContext ** | ctx, |
AVOutputFormat * | oformat, | ||
const char * | format_name, | ||
const char * | filename | ||
) |
Allocate an AVFormatContext for an output format. avformat_free_context() can be used to free the context and everything allocated by the framework within it.
