[FFmpeg-user] "Using AVStream.codec ... deprecated, use AVStream.codecpar instead" on output to wav

[Ashley Hooper]

Hi all,
I'm trying to convert an mp3 to wav for input to neroAacEnc as below. This
has always worked in the past, but with the current version of
ffmpeg/avconv in Debian Testing (version 3.1.3-1+b3) no longer does.

The command line I'm using is:

ffmpeg -i "test.mp3" -f wav - | neroAacEnc -ignorelength -if - -q 0.25 -of
"test"


The output looks fine until here, and alas nothing is piped:

[wav @ 0xdb6540] Using AVStream.codec to pass codec parameters to muxers is
deprecated, use AVStream.codecpar instead.
Error code 127 on test.mp3

Is there another way to generate the wav input for piping to neroAacEnc ?

Thanks,
Ash
