  • swresample, swr_convert() segementation fault

    27 mars 2021, par Abhinav Singh

    I m trying to convert audio data from AV_SAMPLE_FMT_S32P(32 bit planner to AV_SAMPLE_FMT_S16(16 bit non-planner). I m using swresample to convert it with below code

    


    int dst_channel_layout = av_get_default_channel_layout(avctx->channels);
    SwrContext* context = swr_alloc_set_opts(
        nullptr,
        dst_channel_layout,
        AV_SAMPLE_FMT_S16,
        avctx->sample_rate,
        avctx->channel_layout, //dest
        avctx->sample_fmt, //dest
        avctx->sample_rate, //dest
        0,
        NULL
    );
swr_init(context);
int dst_nb_samples = av_rescale_rnd(swr_get_delay(context,avctx->sample_rate)+avctx->frame_size,avctx->sample_rate,avctx->sample_rate,AVRounding(1));
uint8_t** dst_data = NULL;
    int dst_linesize = 0;
    int ret = av_samples_alloc_array_and_samples(&dst_data, &dst_linesize, avctx->channels,dst_nb_samples,avctx->sample_fmt,0);
.......
AVFrame* decodedAudioFrame;
swr_convert(context,dst_data,dst_nb_samples,(const uint8_t**)decodedAudioFrame->data[0],decodedAudioFrame->nb_samples);


    


    This is my AVFrame Data Structure
