[Libav-user] Why (c->frame_size = 0) ?

[Joe Flowers]

In the decoding_encoding.c file, I have changed


codec = avcodec_find_encoder(AV_CODEC_ID_MP2);
to
codec = avcodec_find_encoder(AV_CODEC_ID_PCM_S16LE);


but now I get


"Could not allocate -22 bytes for samples buffer"

back from

buffer_size = av_samples_get_buffer_size(NULL, c->channels,
c->frame_size, c->sample_fmt, 0);


Anyone know how I can fix this problem?

Thanks!

Joe
