Struct rsmpeg::avformat::AVFormatContextInput

pub struct AVFormatContextInput { /* fields omitted */ }

Implementations

impl AVFormatContextInput

pub fn as_ptr(&self) -> *const AVFormatContext

pub fn as_mut_ptr(&mut self) -> *mut AVFormatContext

pub unsafe fn set_ptr(&mut self, ptr: NonNull<AVFormatContext>)

Safety

This function should only be called when the pointer is valid and the data it’s pointing to can be dropped.

pub unsafe fn from_raw(raw: NonNull<AVFormatContext>) -> Self

Safety

This function should only be called when the pointer is valid and the data it’s pointing to can be dropped.

pub fn into_raw(self) -> NonNull<AVFormatContext>

impl AVFormatContextInput

pub fn open(filename: &CStr) -> Result<Self>

Create a AVFormatContextInput instance of a file, and find info of all streams.

pub fn dump(&mut self, index: usize, filename: &CStr) -> Result<()>

Dump ffi::AVFormatContext’s info in the “FFmpeg” way.

The index and filename here is just for info printing, it really doesn’t matter.

pub fn read_packet(&mut self) -> Result<Option<AVPacket>>

Return the next packet of a stream. This function returns what is stored in the file, and does not validate that what is there are valid packets for the decoder. It will split what is stored in the file into packets and return one for each call. It will not omit invalid data between valid packets so as to give the decoder the maximum information possible for decoding.

Return Err(_) on error, Return Ok(None) on EOF.

pub fn find_best_stream(
    &self,
    media_type: AVMediaType
) -> Result<Option<(usize, AVCodecRef<'static>)>>

Return the stream index and stream decoder if there is any “best” stream. “best” means the most likely what the user wants.

impl<'stream> AVFormatContextInput

pub fn streams(&'stream self) -> AVStreamRefs<'stream>

Get Iterator of all AVStreams in the ffi::AVFormatContext.

pub fn iformat(&'stream self) -> AVInputFormatRef<'stream>

Get AVInputFormatRef in the AVFormatContextInput.

pub fn metadata(&'stream self) -> Option<AVDictionaryRef<'stream>>

Get metadata of the ffi::AVFormatContext in crate::avutil::AVDictionary. demuxing: set by libavformat in avformat_open_input() muxing: may be set by the caller before avformat_write_header()
