Fields

name: *const i8

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.

mime_type: *const i8

extensions: *const i8

< comma-separated filename extensions

audio_codec: u32

< default audio codec

video_codec: u32

< default video codec

subtitle_codec: u32

< default subtitle codec

flags: i32

can use flags: AVFMT_NOFILE, AVFMT_NEEDNUMBER, AVFMT_GLOBALHEADER, AVFMT_NOTIMESTAMPS, AVFMT_VARIABLE_FPS, AVFMT_NODIMENSIONS, AVFMT_NOSTREAMS, AVFMT_ALLOW_FLUSH, AVFMT_TS_NONSTRICT, AVFMT_TS_NEGATIVE

codec_tag: *const *const AVCodecTag

List of supported codec_id-codec_tag pairs, ordered by “better choice first”. The arrays are all terminated by AV_CODEC_ID_NONE.

priv_class: *const AVClass

< AVClass for the private context

next: *mut AVOutputFormat

priv_data_size: i32

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

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

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

Write a packet. If AVFMT_ALLOW_FLUSH is set in flags, pkt can be NULL in order to flush data buffered in the muxer. When flushing, return 0 if there still is more data to flush, or 1 if everything was flushed and there is no more buffered data.

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

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

A format-specific function for interleavement. If unset, packets will be interleaved by dts.

query_codec: Option<unsafe extern "C" fn(u32, i32) -> i32>

Test if the given codec can be stored in this container.

@return 1 if the codec is supported, 0 if it is not. A negative number if unknown. MKTAG(‘A’, ‘P’, ‘I’, ‘C’) if the codec is only supported as AV_DISPOSITION_ATTACHED_PIC

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

control_message: Option<unsafe extern "C" fn(*mut AVFormatContext, i32, *mut c_void, u64) -> i32>

Allows sending messages from application to device.

write_uncoded_frame: Option<unsafe extern "C" fn(*mut AVFormatContext, i32, *mut *mut AVFrame, u32) -> i32>

Write an uncoded AVFrame.

See av_write_uncoded_frame() for details.

The library will free *frame afterwards, but the muxer can prevent it by setting the pointer to NULL.

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.

data_codec: u32

< default data codec

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

Initialize format. May allocate data here, and set any AVFormatContext or AVStream parameters that need to be set before packets are sent. This method must not write output.

Return 0 if streams were fully configured, 1 if not, negative AVERROR on failure

Any allocations made here must be freed in deinit().

deinit: Option<unsafe extern "C" fn(*mut AVFormatContext)>

Deinitialize format. If present, this is called whenever the muxer is being destroyed, regardless of whether or not the header has been written.

If a trailer is being written, this is called after write_trailer().

This is called if init() fails as well.

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

Set up any necessary bitstream filtering and extract any extra data needed for the global header. Return 0 if more packets from this stream must be checked; 1 if not.
