v7 aevalsrc filter error

tikuma-lsuhsc commented 2 months ago

The following command with the aevalsrc filter as an input fails in Windows v7 build:

ffmpeg -f lavfi -i "aevalsrc=sin(420*2*PI*t)|cos(430*2*PI*t):c=FC|BC" -t 1  -

The filter definition is straight out of the documentation. The log reads as follows:

The CI for my ffmpegio Python package flagged this error only in Windows environment (more accurately the same test passes in Ubuntu and the CI hasn't reached MacOS run yet due to this error in Windows), and this same command has been working in the previous FFmpeg versions. For your reference, here is the link to the GitHub test summary for your reference.

Thanks for looking into this.

The API used to parse the channel layout changed in 7.0. Your Ubuntu CI uses 6.1.

Change to c=FC+BC

Ah. Thanks for the clarification. So the online documentation is behind too. Will fix the CI accordingly (or rather drop the channel option).
