No Audio in output file if -ss is specified after -i in newer builds

Description
Summary of the bug: With the newer builds, some files (I've replicated with TS and WTV so far) don't have or have corrupted audio in the output file if the -ss is specified after -i. If it's specified before -i the audio is fine.
The sample file is too large to upload here (that itself is cut from the original file which is much larger).
It can be downloaded from:

I'm using WMP 12 (Windows 7) and there is no Audio when I put -ss after -i but I get audio when I put -ss before -i
I noticed you're using a Dec 13th build - I will try it again and let you know.

Replying to ramitbhalla:

I noticed you're using a Dec 13th build - I will try it again and let you know.
It will be sufficient if you test with ffmpeg to see that audio is only missing in WMP.
Could you do the bisect to find the change introducing the regression?
comment:4 by , 12 years ago
The Dec 13th Build is not yet released for Windows.
Unfortunately, regarding Bisect, I googled it but don't know how to use it. I also don't have the ability to build ffmpeg, I rely on Zeronae static builds.
I'll be happy to test the versions and let you know what works and what doesn't but will need to reply on your skills for the "bisect" :)
comment:5 by , 12 years ago
Please run "ffmpeg -i test1.ts" to clarify that your problem is only reproducible with WMP, not with any other player / application.

When you say run "ffmpeg -i test1.ts", what exactly am I looking for in the output? The output looks the same for the working version and the broken version of ffmpeg. However it's the WMP player that unable to play.

I don't think so / complete, uncut console output missing.
However it's the WMP player that unable to play.
You mean the file that you produced with 2f74f8d and that does not play with WMP decodes fine with ffmpeg? It did not work for me.

That's correct, when play test1.ts in WMP 12, I get no audio, in between there are a few squeaks but no audio for the most.
When I run the command, here is what get:

This does not look like an audio stream that FFmpeg can decode and should answer the question what you are looking for in the console output.

Okay, so here's the issue, one side of the problem has been fixed but it ended up breaking the other.
Now specifying -ss after -i works fine, but using -ss before -i now breaks ffmpeg.
See below:
