Extra flags that can be used in pw_stream_connect()
| Enumerator | |
|---|---|
| PW_STREAM_FLAG_NONE | no flags |
| PW_STREAM_FLAG_AUTOCONNECT | try to automatically connect this stream |
| PW_STREAM_FLAG_INACTIVE | start the stream inactive, pw_stream_set_active() needs to be called explicitly |
| PW_STREAM_FLAG_MAP_BUFFERS | mmap the buffers |
| PW_STREAM_FLAG_DRIVER | be a driver |
| PW_STREAM_FLAG_RT_PROCESS | call process from the realtime thread. You MUST use RT safe functions in the process callback. |
| PW_STREAM_FLAG_NO_CONVERT | don't convert format |
| PW_STREAM_FLAG_EXCLUSIVE | require exclusive access to the device |
| PW_STREAM_FLAG_DONT_RECONNECT | don't try to reconnect this stream when the sink/source is removed |
| PW_STREAM_FLAG_ALLOC_BUFFERS | the application will allocate buffer memory. In the add_buffer event, the data of the buffer should be set |

| int pw_stream_flush | ( | struct pw_stream * | stream, |
