fix first-slice parsing with stap-a video frame #11

Open ArmstrongCN opened 1 year ago

ArmstrongCN commented 1 year ago

This PR mainly does tow things.

  1. fix the start_offset for H264BitstreamParser::IsFirstSliceInFrame while parsing with H264::NaluType::kIdr or H264::NaluType::kSlice in a stap-a packet.

In absl::optional ProcessStapAOrSingleNalu function, start_offset steps over nalu_type field.

start_offset += H264::kNaluTypeSize;

In H264BitstreamParser::IsFirstSliceInFrame, slice_reader steps over nalu_type field again.

  1. optimize the is_real_first_packet_in_frame assignment, remove duplicated bitstream parsing.
