I do have a 96000 Hz FLAC file which I would like to convert to DTS and
preserve the sample rate. But it seems only 41000 and 48000 is supported.

Thanks, this did the trick! Now it builds as expected. Yippee! But why
does an older ffmpeg build without this extra-ldflag?

I do. This dependencies are so many, because I need them for other
projects. There are not all related to FFmpe
Can nobody help me with my problem? I am really lost here.The only thing
I didn't try until now is to install the dependencies via Homebrew
instead of Macports. But this should not make a difference, I think.

Yes, I also found this out just now. Installing pkg-config via Macport
I don't know what was happening, but I'm not able anymore to build

As I read on wikipedia and some forums, a DTS bitstream, based on the
Coherent Acoustics compression algorithm, is actually encapsulated in
each PCM audio track, which is a "pseudo 2-channel wav".
I've tried a combination of both current suggestions, but this gives me
an error:

Hi, ffmpeg user list. I have a problem that I can not solve and hope you
can help me.
I found out, that I can listen to 5.1 surround music over iTunes /
Airplay if the music is an dts-encoded WAV file (44.1 kHz, 16 Bit). This
means I have to convert all my surround music, mostly *.dts, *.flac or
