Hi Luca,

* technical: For the double buffer output, i shunt my process when i
obtain the ouput AVFrame and use it's data. Is it the recommended way?
if you feed the avframe to the avresample yes, otherwise you should
treat that data as quasi-opaque.
BTW, is there a recommended way to do what i want?
demux -> decode -> resample -> your application
That should be enough.
Thanks for your answer
Indeed, i feed the AVFrame to the avresample. And after that, i convert
to double data using the following code
uint8_t* data = oframe->data[0];
for (int i = 0; i < oframe->nb_samples; ++i) {
//divide by uint8_max to transform into double between 0 and 1
_outBuffer[i] = (double) (data[i] - (UINT8_MAX / 2)) /
(double) (UINT8_MAX/2);
}
Hence i get double values ranging from -1 to 1. But I think that's not
the right way to do this.
Should i do something like:
avresample_convert(avr, (double*)oframe->data, oframe->linesize[0],
frame->nb_samples, frame->data, frame->linesize[0], frame->nb_samples);
to let the avresample do the conversion? Is there any helper function?
Thanks
Florian
