Parse a packet.
s | parser context. |
avctx | codec context. |
poutbuf | set to pointer to parsed buffer or NULL if not yet finished. |
poutbuf_size | set to size of parsed buffer or zero if not yet finished. |
buf | input buffer. |
buf_size | input length, to signal EOF, this should be 0 (so that the last frame can be output). |
pts | input presentation timestamp. |
dts | input decoding timestamp. |
pos | input byte position in stream. |
