Really I have no luck: For months I try to find fix for ffmpeg with
alsa, as I got statics in the audio. Ubuntu, Ubuntu studio, Mint,
Centos, Stella, Fedora, have the same issue (New OS install on a spare
HD for each of them).

This month, I found out that with pulse, audio is good. I was happy.

Now I have an error with Duration...
I tried -ts abs then -ts mono2abs, (wallclock is the same as abs)

Duration: N/A, start: 1437900701.356327
Duration: N/A, start: 1437900702.504357
...
Cliping frame in rate conversion by 0.000008
Cliping frame in rate conversion by 0.199486
...
Past duration 0.600685 too large


I even tried -force_key_frames 00:00:00.000 (found in another forum),
same issue.
Same issue with alsa (+ statics)

So, I am a bit hopeless, and it's raining again outside. :-(
I am sorry, I don't want to take advantage of your kindness, Carl,
Moritz, but I'll need your help again.

So, what do you want I do?
