- * @note You might have to align the input buffer avpkt->data.
- * The alignment requirements depend on the CPU: on some CPUs it isn't
- * necessary at all, on others it won't work at all if not aligned and on others
- * it will work but it will have an impact on performance.

- * In practice, avpkt->data should have 4 byte alignment at minimum.

* @note Codecs which have the CODEC_CAP_DELAY capability set have a delay
* between input and output, these need to be fed with avpkt->data=NULL,
* avpkt->size=0 at the end to return the remaining frames.
