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. |
