## Description

## Functions

### GstGLAsyncDebugLogGetMessage ()

    gchar *
    (*GstGLAsyncDebugLogGetMessage) (gpointer user_data);

### gst_gl_async_debug_new ()

    GstGLAsyncDebug *
    gst_gl_async_debug_new (void);

Free with `gst_gl_async_debug_free()`

[skip]

#### Returns

a new GstGLAsyncDebug

Since: 1.8

### gst_gl_async_debug_free ()

    void
    gst_gl_async_debug_free (GstGLAsyncDebug *ad);

Frees `ad`

#### Parameters

ad | a GstGLAsyncDebug |

Since: 1.8

### gst_gl_async_debug_init ()

    void
    gst_gl_async_debug_init (GstGLAsyncDebug *ad);

Initialize `ad` . Intended for use with GstGLAsyncDebug's that are embedded in other structs.

#### Parameters

ad | a GstGLAsyncDebug |

Since: 1.8

### gst_gl_async_debug_unset ()

    void
    gst_gl_async_debug_unset (GstGLAsyncDebug *ad);

Unset any dynamically allocated data. Intended for use with GstGLAsyncDebug's that are embedded in other structs.

#### Parameters

ad | a GstGLAsyncDebug |

### gst_gl_async_debug_freeze ()

    void
    gst_gl_async_debug_freeze (GstGLAsyncDebug *ad);

freeze the debug output. While frozen, any call to `gst_gl_async_debug_output_log_msg()` will not output any messages but subsequent calls to `gst_gl_async_debug_store_log_msg()` will overwrite previous messages.

#### Parameters

ad | a GstGLAsyncDebug |

Since: 1.8

### gst_gl_async_debug_thaw ()

    void
    gst_gl_async_debug_thaw (GstGLAsyncDebug *ad);

unfreeze the debug output. See `gst_gl_async_debug_freeze()` for what freezing means

#### Parameters

ad | a GstGLAsyncDebug |

Since: 1.8

### gst_gl_async_debug_output_log_msg ()

    void
    gst_gl_async_debug_output_log_msg (GstGLAsyncDebug *ad);

Outputs a previously stored debug message.

#### Parameters

ad | the GstGLAsyncDebug to store the message in |

### gst_gl_async_debug_store_log_msg ()

    void
    gst_gl_async_debug_store_log_msg (GstGLAsyncDebug *ad,
                                      GstDebugCategory *cat,
                                      GstDebugLevel level,
                                      const gchar *file,
                                      const gchar *function,
                                      gint line,
                                      GObject *object,
                                      const gchar *format,
                                      ...);

Stores a debug message for later output by `gst_gl_async_debug_output_log_msg()`

#### Parameters

ad | the GstGLAsyncDebug to store the message in |
cat | the GstDebugCategory to output the message in |
level | the GstLevel |
file | the file where the debug message originates from |
function | the function where the debug message originates from |
line | the line in `file` where the debug message originates from |
object | a GObject to associate with the debug message. | [allow-none]
format | a printf style format string |
... | the list of arguments for `format` |

Since: 1.8
