[FFmpeg-user] swr_convert from packed to planar

[Livio Tenze]

Dear all,

I am trying to use the swr_convert function to convert (format and
resample) an audio stream with dual channels from AV_SAMPLE_FMT_U8
to AV_SAMPLE_FMT_FLTP.

The problem is that the samples, after calling swr_convert, are all zeros.
I checked the source samples and they differ from zero.

885->0.00

691->0.00

1116->0.00

783->0.00

1067->0.00

885->0.00

875->0.00

855->0.00

993->0.00

878->0.00
Is it possible to use swr_convert to resample and convert audio
samples from AV_SAMPLE_FMT_U8 to AV_SAMPLE_FMT_FLTP?

Thanks in advance.
Livius
