  • Ticket #9422 – Description

    initial v6  
    11Summary of the bug:
    2 I have a mpegts sample that a PMT's descriptor overflows resulting in incorrect streams. I wasn't able to connect to the FTP upload.ffmpeg.org server to send this sample. (What should I do?)

    44In that sample, the PMT has a program_info_length of 12 bytes. First, there is a descriptor ID 5, 4 bytes long. Then, it appears like there is an ID 1 descriptor, 15 bytes long. This overflows the program_info_length of 12 bytes.
