Wrong duration in TS container

[Heesuk Jung]

Summary of the bug:

In some TS file case, libavformat get wrong duration
and so there are some problem when the file is played.

1. 1st problematic file case
   • link : ​https://docs.google.com/open?id=0B6r7ZfWFIypCN0Q2VmZiUHdsQW8
   • incorrect duration based on libavformat : 24:08:38.61
   • correct duration : 00:01:12.00

2. 2nd problematic file case
   • link : ​https://docs.google.com/open?id=0B6r7ZfWFIypCNFVuWHowMFBBN0E
   • incorrect duration based on libavformat : 00:03:15.50
   • correct duration : 00:00:21.30

How to reproduce:
% ffprobe 473_TP_MPEG2[Main@High@1419Kbps@1080p@29.970fps]_AC3[384Kbps@48kHz@16bit@2ch].tp

[Carl Eugen Hoyos]

To make this a valid ticket, please add the complete, uncut console output of "ffmpeg -i \[2\]\ trp_MPEG2_MP2.trp -f null -" and / or "ffmpeg -i 473_TP_MPEG2\[Main\@High\@1419Kbps\@1080p\@29.970fps\]_AC3\[384Kbps\@48kHz\@16bit\@2ch\].tp -f null -"
(The output will show both the calculated duration and the actual duration.)

Hi Liu,

Please check your problematic file with 0001-Wrong-duration-in-TS-container-Ticket-1836.2.patch. I did regression test for 472 files and tried to transcode from some MKV file according to your ffmpeg comand.
All test result is OK and it does not happen "Floating point exception ".
If you still have some problem, let me know problematic file link.
(I recommend that you did test with latest master. Because I submitted other related patch for this issue)

Thanks !

Hi Liu,

Please check update latest patch.

Is this problem fixed?

[Heesuk Jung]

This problem is partially fixed and 2nd problematic file is not fixed.
(I found solution resolving 2nd problematic file but the solution makes some side effect in other files.)
I am trying to consider other approach.

Thanks.

Both files seem to get a good duration with latest ffmpeg.
Dont know which commit fixed the second file though

[Carl Eugen Hoyos]

First file fixed in 5442c6c, second file fixed in faa0068, see ticket #2018
