Detailed Description
Context used by codec threads and stored in their AVCodecContext thread_opaque.
Member Enumeration Documentation
| anonymous enum |
| Enumerator | |
|---|---|
| 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_GET_FORMAT |
Set when the codec calls get_format(). State is returned to STATE_SETTING_UP afterwards. |
| STATE_SETUP_FINISHED |
Set after the codec has called ff_thread_finish_setup(). |
