Fields

name: *const i8

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

long_name: *const i8

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.

flags: i32

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.

extensions: *const i8

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

codec_tag: *const *const AVCodecTag

priv_class: *const AVClass

< AVClass for the private context

mime_type: *const i8

Comma-separated list of mime types. It is used check for matching mime types while probing. @see av_probe_input_format2

next: *mut AVInputFormat

raw_codec_id: i32

Raw demuxers store their codec ID here.

priv_data_size: i32

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

read_probe: Option<unsafe extern "C" fn(*const AVProbeData) -> i32>

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.

read_header: Option<unsafe extern "C" fn(*mut AVFormatContext) -> i32>

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

read_packet: Option<unsafe extern "C" fn(*mut AVFormatContext, *mut AVPacket) -> i32>

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). @return 0 on success, < 0 on error. Upon returning an error, pkt must be unreferenced by the caller.

read_close: Option<unsafe extern "C" fn(*mut AVFormatContext) -> i32>

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

read_seek: Option<unsafe extern "C" fn(*mut AVFormatContext, i32, i64, i32) -> i32>

Seek to a given timestamp relative to the frames in stream component stream_index. @param stream_index Must not be -1. @param flags Selects which direction should be preferred if no exact match is available. @return >= 0 on success (but not necessarily the new offset)

read_timestamp: Option<unsafe extern "C" fn(*mut AVFormatContext, i32, *mut i64, i64) -> i64>

Get the next timestamp in stream[stream_index].time_base units. @return the timestamp or AV_NOPTS_VALUE if an error occurred

read_play: Option<unsafe extern "C" fn(*mut AVFormatContext) -> i32>

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

read_pause: Option<unsafe extern "C" fn(*mut AVFormatContext) -> i32>

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

read_seek2: Option<unsafe extern "C" fn(*mut AVFormatContext, i32, i64, i64, i64, i32) -> i32>

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.

get_device_list: Option<unsafe extern "C" fn(*mut AVFormatContext, *mut AVDeviceInfoList) -> i32>

Returns device list with it properties. @see avdevice_list_devices() for more details.

create_device_capabilities: Option<unsafe extern "C" fn(*mut AVFormatContext, *mut AVDeviceCapabilitiesQuery) -> i32>

Initialize device capabilities submodule. @see avdevice_capabilities_create() for more details.

free_device_capabilities: Option<unsafe extern "C" fn(*mut AVFormatContext, *mut AVDeviceCapabilitiesQuery) -> i32>

Free device capabilities submodule. @see avdevice_capabilities_free() for more details.
