Implementations§

Source§

impl TSReader

Source

pub fn new( filename: &str, buf_reader: BufReader<File>, ) -> Result<Self, Box<dyn Error>>

Create a new TSReader instance using the given file.

This function also finds the first SYNC byte, so we can determine the alignment of the transport packets.

§Parameters
  • buf_reader: a buffered reader that contains transport stream data.
Source

pub fn next_packet_unchecked(&mut self) -> Option<TSPacket>

Read the next packet from the transport stream file.

This function returns None for any Err in order to prevent the need for .unwrap() calls in more concise code.

§Returns

Some(TSPacket) if the next transport stream packet could be parsed from the file. None if the next transport stream packet could not be parsed from the file for any reason. This includes if the entire file has been fully read.

Source

pub fn next_packet(&mut self) -> Result<Option<TSPacket>, Box<dyn Error>>

Read the next packet from the transport stream file.

§Returns

Ok(Some(TSPacket)) if the next transport stream packet could be parsed from the file. Ok(None) if there was no issue reading the file and no more TS packets can be read.

Source

pub fn next_payload_unchecked(&mut self) -> Option<Box<[u8]>>

Read the next payload from the transport stream file.

This function returns None for any Err in order to prevent the need for .unwrap() calls in more concise code.

§Returns

Some(TSPayload) if the next transport stream packet could be parsed from the file. None if the next transport stream payload could not be parsed from the file for any reason. This includes if the entire file has been fully read.

Source

pub fn next_payload(&mut self) -> Result<Option<Box<[u8]>>, Box<dyn Error>>

Read the next full payload from the file.

This function parses through all transport stream packets, stores them in a buffer and concatenates their payloads together once a payload has been complete.

Source

pub fn sync_byte_alignment(&self) -> u64

Return the alignment of the SYNC bytes in this reader.

Source

pub fn add_tracked_pid(&mut self, pid: u16)

Add a PID to the tracking list.

Only tracked PIDs are returned when running methods that gather packets or payloads. If no PID is specified then all PIDs are returned.

Source

pub fn remove_tracked_pid(&mut self, pid: u16)

Remove this PID from being tracked.

Only tracked PIDs are returned when running methods that gather packets or payloads. If no PID is specified then all PIDs are returned.
