| Input packet (for decoding) or output (for encoding). | |
| int | allocated_buf_size |
| Size allocated for avpkt.data. | |
| AVFrame | frame |
| Output frame (for decoding) or input (for encoding). | |
| int | got_frame |

| int | result |
| The result of the last codec decode/encode() call. | |
| enum PerThreadContext:: { ... } | state |
| AVFrame | released_buffers [MAX_BUFFERS] |
| Array of frames passed to ff_thread_release_buffer(). | |
| int | num_released_buffers |
| volatile int | progress [MAX_BUFFERS][2] |

Definition at line 93 of file pthread.c.
| anonymous enum |
| STATE_INPUT_READY | Set when the thread is awaiting a packet. |
| STATE_SETTING_UP | Set before the codec has called ff_thread_finish_setup(). |
| STATE_GET_BUFFER |
Set when the codec calls get_buffer().
State is returned to STATE_SETTING_UP afterwards. |
| STATE_SETUP_FINISHED | Set after the codec has called ff_thread_finish_setup(). |
Size allocated for avpkt.data.
