FFMpeg unable to determine video length with streams outside of programs

Description

Summary of the bug:
FFMpeg is unable to determine the length of a mpegts stream when there are streams detected outside of programs.

It seems that having 1 tiny section of the stream that has these streams outside of programs can causes the whole stream to be effected.

I have split a 8.39gb stream with the problem into 31.5mb chucks and was able to find a specific chuck with the problem (all the other chunks reported fine).

I have attached the effected part, but can provide other parts if necessary.

How to reproduce:

  • Component changed from FFmpeg to avformat
  • Keywords mpegts added; No Program removed

This depends at the moment on ticket #2441.

However, please upload a sample that allows to reproduce your original problem to http://www1.datafilehost.com/
Is this also reproducible with current git head?

  • Version changed from 1.2 to git-master

I wonder if there is a bug:
FFmpeg reports "max_analyze_duration reached" and raising the value fixes the issue:

The teletext streams are empty afaict, so misdetecting them is no bug imo.

Both programs contain a teletext stream with subtitles.

comment:6 Changed 4 years ago by cehoyos

  • Resolution set to invalid
  • Status changed from new to closed

If I cut the sample in a 10M and a 20M segment, both segments show the whole scene for one of the two programs. Afaict, this indicates that two independent transport streams were concatenated, I don't think "duration" makes sense for such a file.
Please reopen if you think my analysis is wrong.
