avcodec/aptxdec: Process data in complete blocks only The APTX (HD) decoder decodes blocks of four (six) bytes to four output samples. It makes no sense to handle incomplete blocks: They would just lead to synchronization errors, in which case the complete frame is discarded. So only handle complete blocks. This also avoids reading from the packet's padding and writing into the frame's padding.
