Sorry, forgot the code:
void AVConverter::decode_audio()
{
out.audio.outbuf_size = AVCODEC_MAX_AUDIO_FRAME_SIZE * 2;
if ( ( out.audio.outbuf_size = avcodec_decode_audio2 (
in.audio.codec_ctx, out.audio.samples,
&out.audio.outbuf_size,
in.packet->data, in.packet->size ) ) <= 0
)
{
error = CouldNotDecodeAudioFrame;
}
if ( in.audio.codec_ctx->sample_rate != out.audio.codec_ctx->sample_rate
|| out.audio.codec_ctx->channels != in.audio.codec_ctx->channels )
{
int16_t* buffer = ( int16_t* ) av_malloc (
AVCODEC_MAX_AUDIO_FRAME_SIZE * 2 );
int isize =
av_get_bits_per_sample_format(out.audio.codec_ctx->sample_fmt)/8;
ReSampleContext *rsctx = av_audio_resample_init (
out.audio.codec_ctx->channels,
in.audio.codec_ctx->channels,
out.audio.codec_ctx->sample_rate,
in.audio.codec_ctx->sample_rate,
out.audio.codec_ctx->sample_fmt,
in.audio.codec_ctx->sample_fmt,
16, 10, 0, 0.8 );
int size = audio_resample ( rsctx, buffer, out.audio.samples, 2 );
AVResampleContext *avrsctx = av_resample_init (
out.audio.codec_ctx->sample_rate, in.audio.codec_ctx->sample_rate,
16, 10, 0, 0.8 );
int consumed;
if ( av_resample ( avrsctx, buffer, out.audio.samples, &consumed,
out.audio.outbuf_size/isize,
AVCODEC_MAX_AUDIO_FRAME_SIZE*2, 0 ) <= 0 )
{
return;
}
out.audio.samples = buffer;
out.audio.outbuf_size = size;
av_freep ( &buffer );
av_freep ( &rsctx );
}
}
thanks,
