[FFmpeg-devel] [PATCH] avformat/adxdec: check avctx->channels for invalid values

[Andreas Cadhalpun]

Hi,

if avctx->channels is 0 in adx_read_packet, size gets set to 0, av_get_packet 
sets pkt->data to NULL and then AV_RB16(pkt->data) results in a null pointer 
dereference.

Attached patch fixes this.

Best regards,
Andreas
