PocReader

frame_source::h264_poc

Struct PocReader 

Source 
pub struct PocReader { /* private fields */ }
Expand description

Accumulates the H.264 parsing context (SPS/PPS) and the POC strategy as samples are read, so a whole file can be walked (in decode order) and each frame’s picture order count reconstructed the same way.

Implementations§

Source§

impl PocReader

Source

pub fn new() -> Self

Source

pub fn seed_from_container<H: SeekableH264Source>( &mut self, src: &H264Source<H>, ) -> Result<()>

Seed SPS/PPS from container-level metadata (MP4). No-op for Annex B, which carries them inline (handled in Self::poc_for_frame).

Source

pub fn poc_for_frame(&mut self, nals: &[Vec<u8>]) -> Result<i64>

Feed any inline SPS/PPS (Annex B) carried with this frame, then return the frame’s POC.
