Okay, I tried using swr_convert, but it always crashes when trying to
divide by 0.
Basically, I have the same problem as those two guys:
http://stackoverflow.com/questions/14448413/why-am-i-getting-fpe-when-using-swresample-1-1
and
https://ffmpeg.org/trac/ffmpeg/ticket/1834
However, I DO call swr_init() and there is no error whatsoever.
And it never reaches the point in swr_init() where context->postin would
be set so it HAS to crash there.
Here is the code I use to init and to the swr_convert:
// Init context
SwrContext* swrContext = swr_alloc_set_opts(NULL,
audioCodecContext->channel_layout, AV_SAMPLE_FMT_S16P,
audioCodecContext->sample_rate,
audioCodecContext->channel_layout,
audioCodecContext->sample_fmt, audioCodecContext->sample_rate,
0, NULL);
int result = swr_init(swrContext);
// Conversion
int outputSamples = swr_convert(swrContext,
&p_destBuffer, 2048,
(const
uint8_t**)p_frame->extended_data, p_frame->nb_samples);
As I said, I receive no errors, but the crash when FFmpeg tries to
divide by 0 inside |swri_realloc_audio|.
What am I doing wrong?

Well. I don't.
I was assuming that decode_audio4(...) was already giving output in
that format. I mean, after decoding, the data has to be in SOME
format, so I assumed it was a standard format. Possibly a bit naive on
my part.
But then again, not a single sample with FFmpeg & OpenAL I found was
using aresample, so this is the first time I actually hear of it.
I will try using it now and see how well that goes.

Where do you call libswresample or aresample to convert
from AV_SAMPLE_FMT_FLTP to AV_SAMPLE_FMT_S16 ?
