Field Documentation

◆ name

const char* AVInputFormat::name

A comma separated list of short names for the format.

New names may be appended with a minor bump.

Definition at line 554 of file avformat.h.

Referenced by av_dump_format(), av_find_input_format(), av_probe_input_format3(), avformat_find_stream_info(), estimate_timings(), hls_read_header(), hls_read_packet(), ifile_open(), LLVMFuzzerTestOneInput(), print_times(), probe(), read_gab2_sub(), read_thread(), set_codec_from_probe_data(), show_format(), show_formats_devices(), and show_help_demuxer().

◆ long_name

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.

Definition at line 561 of file avformat.h.

Referenced by show_format(), show_formats_devices(), and show_help_demuxer().

◆ flags

int AVInputFormat::flags

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

Definition at line 568 of file avformat.h.

Referenced by assert_file_overwrite(), av_probe_input_format3(), avformat_find_stream_info(), dump_stream_format(), estimate_timings(), ff_img_read_header(), ifile_open(), print_times(), probe(), read_thread(), show_stream(), and ts_discontinuity_detect().

◆ extensions

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

Definition at line 575 of file avformat.h.

Referenced by av_probe_input_format3(), LLVMFuzzerTestOneInput(), and show_help_demuxer().

◆ codec_tag

const struct AVCodecTag* const * AVInputFormat::codec_tag

Definition at line 577 of file avformat.h.

◆ priv_class

const AVClass* AVInputFormat::priv_class

AVClass for the private context.

Definition at line 579 of file avformat.h.

Referenced by avformat_find_stream_info(), ff_alloc_input_device_context(), format_child_class_iterate(), ifile_open(), next_input(), show_format_opts(), show_formats_devices(), show_help_demuxer(), and show_stream().

◆ mime_type

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

Definition at line 586 of file avformat.h.

Referenced by av_probe_input_format3().

◆ raw_codec_id

int AVInputFormat::raw_codec_id

Raw demuxers store their codec ID here.

Definition at line 598 of file avformat.h.

Referenced by ff_img_read_header(), ff_img_read_packet(), hls_read_header(), and rawvideo_read_header().

◆ priv_data_size

int AVInputFormat::priv_data_size

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

Definition at line 603 of file avformat.h.

◆ flags_internal

int AVInputFormat::flags_internal

Internal flags.

See FF_FMT_FLAG_* in internal.h.

Definition at line 608 of file avformat.h.

◆ read_probe

int(* AVInputFormat::read_probe) (const 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.

Definition at line 615 of file avformat.h.

Referenced by av_probe_input_format3(), ff_img_read_header(), and probe().

◆ read_header

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.

Definition at line 622 of file avformat.h.

Referenced by ff_img_read_header().

◆ read_packet

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. Upon returning an error, pkt must be unreferenced by the caller.

Definition at line 632 of file avformat.h.

Referenced by ff_img_read_packet().

◆ read_close

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

Close the stream.

The AVFormatContext and AVStreams are not freed by this function

Definition at line 638 of file avformat.h.

◆ read_seek

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_index	Must not be -1.
flags	Selects which direction should be preferred if no exact match is available.

Returns: >= 0 on success (but not necessarily the new offset)

Definition at line 648 of file avformat.h.

◆ read_timestamp

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

Definition at line 655 of file avformat.h.

Referenced by ff_seek_frame_binary().

◆ read_play

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

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

Definition at line 662 of file avformat.h.

◆ read_pause

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

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

Definition at line 668 of file avformat.h.

◆ read_seek2

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.

Definition at line 676 of file avformat.h.

◆ get_device_list

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.

Definition at line 682 of file avformat.h.
