Description

Apparently sample rate in the header of the mkv of recording doesn't match the contents which makes it impossible to watch it on players like omxplayer.

Please find attached the example file: "Lanterna-Verde.2013-12-29.mkv".

ffmpeg -i Lanterna-Verde.2013-12-29.mkv claims the audio tracks are Audio: aac, 48000 Hz, stereo, fltp (default)
mkvinfo Lanterna-Verde.2013-12-29.mkv claims the audio tracks are Sampling frequency: 24000

What does the recording log say about the sample rate? does it happen every time, or just occasionally?

The log displays sample 2400 and it does happen every time.

Here's an example of the recording log:
"DiBcom 7000PC", network: "TDT Continente", mux: "TDT Continente: 754,000 kHz", provider: "", service: "RTP 2"

Okey, could you provide us with a mux dump or a pass through recording (pmt/pat rewrite disabled).

Sorry to dig up this issue...
Here is the mux dump. I've noticed that the sample error only happens when using mkv (and not with the pass through).

thanks

I believe that it's fixed in recent release. Create a new issue,if this problem exists for 4.x.
