[FFmpeg-user] mcompand

[Martin Rouillard]

Thanks Paul, This helped but I still have an error on the attack and decays
count, here is my command :

-af "mcompand=0.1 0.2 6 -47/-40 -34/-34 -17/-33 100 | 0.1 0.2 6 -47/-40
-34/-34 -17/-33 400 | 0.1 0.2 6 -47/-40 -34/-34 -15/-33 1600 | 0.1 0.2 6
-47/-40 -34/-34 -31/-31 -0/-30 6400 | 0.1 0.2 6 -38/-31 -28/-28 -0/-25
22000"

and the error I get is :

[Parsed_mcompand_0 @ 0x5294d40] number of attacks rate plus decays rate
must be even
[Parsed_mcompand_0 @ 0x5294d40] Failed to configure output pad on
Parsed_mcompand_0
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
Conversion failed!

Best Regards,
