Member Data Documentation

const struct AVCodecTag* const* AVInputFormat::codec_tag
int(* AVInputFormat::create_device_capabilities) (struct AVFormatContext *s, struct AVDeviceCapabilitiesQuery *caps)

Initialize device capabilities submodule.

See also
avdevice_capabilities_create() for more details.
const char* AVInputFormat::extensions

If extensions are defined, then no probe is done. You should usually not use extension format guessing because it is not reliable enough

int AVInputFormat::flags

Can use flags: AVFMT_NOFILE, AVFMT_NEEDNUMBER, AVFMT_SHOW_IDS, AVFMT_GENERIC_INDEX, AVFMT_TS_DISCONT, AVFMT_NOBINSEARCH, AVFMT_NOGENSEARCH, AVFMT_NO_BYTE_SEEK, AVFMT_SEEK_TO_PTS.

int(* AVInputFormat::free_device_capabilities) (struct AVFormatContext *s, struct AVDeviceCapabilitiesQuery *caps)

Free device capabilities submodule.

See also
avdevice_capabilities_free() for more details.
int(* AVInputFormat::get_device_list) (struct AVFormatContext *s, struct AVDeviceInfoList *device_list)

Returns device list with it properties.

See also
avdevice_list_devices() for more details.
const char* AVInputFormat::long_name

Descriptive name for the format, meant to be more human-readable than name. You should use the NULL_IF_CONFIG_SMALL() macro to define it.

const char* AVInputFormat::mime_type

Comma-separated list of mime types. It is used check for matching mime types while probing.

See also
av_probe_input_format2
const char* AVInputFormat::name

A comma separated list of short names for the format. New names may be appended with a minor bump.

struct AVInputFormat* AVInputFormat::next
const AVClass* AVInputFormat::priv_class

AVClass for the private context.

int AVInputFormat::priv_data_size

Size of private data so that it can be allocated in the wrapper.

int AVInputFormat::raw_codec_id

Raw demuxers store their codec ID here.

int(* AVInputFormat::read_close) (struct AVFormatContext *)

Close the stream. The AVFormatContext and AVStreams are not freed by this function

int(* AVInputFormat::read_header) (struct AVFormatContext *)

Read the format header and initialize the AVFormatContext structure. Return 0 if OK. 'avformat_new_stream' should be called to create new streams.

int(* AVInputFormat::read_packet) (struct AVFormatContext *, AVPacket *pkt)

Read one packet and put it in 'pkt'. pts and flags are also set. 'avformat_new_stream' can be called only if the flag AVFMTCTX_NOHEADER is used and only in the calling thread (not in a background thread).

Returns
0 on success, < 0 on error. When returning an error, pkt must not have been allocated or must be freed before returning
int(* AVInputFormat::read_pause) (struct AVFormatContext *)

Pause playing - only meaningful if using a network-based format (RTSP).

int(* AVInputFormat::read_play) (struct AVFormatContext *)

Start/resume playing - only meaningful if using a network-based format (RTSP).

int(* AVInputFormat::read_probe) (AVProbeData *)

Tell if a given file has a chance of being parsed as this format. The buffer provided is guaranteed to be AVPROBE_PADDING_SIZE bytes big so you do not have to check for that unless you need more.

int(* AVInputFormat::read_seek) (struct AVFormatContext *, int stream_index, int64_t timestamp, int flags)

Seek to a given timestamp relative to the frames in stream component stream_index.

Parameters
stream_indexMust not be -1.
flagsSelects which direction should be preferred if no exact match is available.
Returns
>= 0 on success (but not necessarily the new offset)
int(* AVInputFormat::read_seek2) (struct AVFormatContext *s, int stream_index, int64_t min_ts, int64_t ts, int64_t max_ts, int flags)

Seek to timestamp ts. Seeking will be done so that the point from which all active streams can be presented successfully will be closest to ts and within min/max_ts. Active streams are all streams that have AVStream.discard < AVDISCARD_ALL.

int64_t(* AVInputFormat::read_timestamp) (struct AVFormatContext *s, int stream_index, int64_t *pos, int64_t pos_limit)

Get the next timestamp in stream[stream_index].time_base units.

Returns
the timestamp or AV_NOPTS_VALUE if an error occurred
