[FFmpeg-devel] Invalid block align in wmav2 encoder

[Sebastien Cote]

Hi,

I am encoding using FFMPEG's wmav2 audio codec and I think there is an error when calculating the block align value.

In wmaenc.c the block align is defined as:

avctx->block_align= s->block_align= avctx->bit_rate*(int64_t)s->frame_len / (avctx->sample_rate*8);


If the sampling rate is 44100 and I am encoding at 64kbps, I get 64000*2048 / (44100 * 8) = 371.5

Shouldn't this value be rounded up to the nearest integer instead of being rounded down?

Thanks,

Sebastien
