Functions

add_log_function

add_ring_buffer_logger

Adds a memory ringbuffer based debug logger that stores up to max_size_per_thread bytes of logs per thread and times out threads after thread_timeout seconds of inactivity.

get_default_threshold

Returns the default threshold that is used for new categories.

get_stack_trace

flags

is_active

Checks if debugging output is activated.

is_colored

Checks if the debugging output should be colored.

print_stack_trace

If libunwind, glibc backtrace or DbgHelp are present a stack trace is printed.

remove_default_log_function

remove_log_function

remove_ring_buffer_logger

Removes any previously added ring buffer logger with [debug_add_ring_buffer_logger()][crate::debug_add_ring_buffer_logger()].

ring_buffer_logger_get_logs

Fetches the current logs per thread from the ring buffer logger. See [debug_add_ring_buffer_logger()][crate::debug_add_ring_buffer_logger()] for details.

set_active

If activated, debugging messages are sent to the debugging handlers. It makes sense to deactivate it for speed issues.

set_colored

Sets or unsets the use of coloured debugging output. Same as gst_debug_set_color_mode () with the argument being being GST_DEBUG_COLOR_MODE_ON or GST_DEBUG_COLOR_MODE_OFF.

set_default_threshold

Sets the default threshold to the given level and updates all categories to use this threshold.

set_threshold_for_name

Sets all categories which match the given glob style pattern to the given level.

set_threshold_from_string

Sets the debug logging wanted in the same form as with the GST_DEBUG environment variable. You can use wildcards such as *, but note that the order matters when you use wild cards, e.g. foosrc:6,*src:3,*:2 sets everything to log level 2.

unset_threshold_for_name

Resets all categories with the given name back to the default level.
