/*When it is not a planar arrangement, data[1] is empty,
and all the data is interleaved in data[0].
This can result in a segmentation fault when accessing data[ch] .*/
//So I delete the code below:
for (i = 0; i < frame->nb_samples; i++)
for (ch = 0; ch < dec_ctx->ch_layout.nb_channels; ch++)
fwrite(frame->data[ch] + data_size*i, 1, data_size, outfile);
//And I write this instead
// L R data order
if (av_sample_fmt_is_planar(dec_ctx->sample_fmt))
{
// planar：LLL...RRR... in different data[ch]
for (ch = 0; ch < dec_ctx->ch_layout.nb_channels; ch++)
{
fwrite(frame->data[ch], 1, frame->linesize[0], outfile); // only
linesize[0] has data.
}
}
else
{
// not planar：LRLR...all in data[0]
fwrite(frame->data[0], 1, frame->linesize[0], outfile);
}
