MPEG-TS - Supplementary tasks

• Reading PCR values (contained in the Adaptation Field), PTS and DTS (contained in the elementary stream packet header extension)
• Parsing and writing the video stream to a file (.264)
• Reading information contained in the “MPEG Audio Frame Header”
• Decoding the audio stream using the mpg123 library (frame by frame, without writing intermediate results to disk) and writing to a WAVE file

Organizational Information

Requirements for passing the labs

• Implementation of a functional MPEG-2 transport stream parser

A working MPEG-2 transport stream parser is one that processes a single audio elementary stream from the transport stream and saves it to a file. This file must be playable by ffplay and sound correct (i.e., without distortion).

Grading system

• Implementation of a working MPEG-2 transport stream parser: Grade = 3.0
• Completion of each additional task: Grade += 0.5
