— Function: gst-type-find-peek (self <gst-type-find*>) (offset int64) (size unsigned-int)   (ret <guint8*>)

Returns the size bytes of the stream to identify beginning at offset. If offset is a positive number, the offset is relative to the beginning of the stream, if offset is a negative number the offset is relative to the end of the stream. The returned memory is valid until the typefinding function returns and must not be freed.

find

The <gst-type-find> object the function was called with

offset

The offset

size

The number of bytes to return

ret

the requested data, or NULL if that data is not available.

— Function: gst-type-find-suggest (self <gst-type-find*>) (probability unsigned-int) (caps <gst-caps>)

If a <gst-type-find-function> calls this function it suggests the caps with the given probability. A <gst-type-find-function> may supply different suggestions in one call. It is up to the caller of the <gst-type-find-function> to interpret these values.

find

The <gst-type-find> object the function was called with

probability

The probability in percent that the suggestion is right

caps

The fixed <gst-caps> to suggest

— Function: gst-type-find-get-length (self <gst-type-find*>)   (ret unsigned-int64)

Get the length of the data stream.

find

The <gst-type-find> the function was called with

ret

The length of the data stream, or 0 if it is not available.

— Function: gst-type-find-register (plugin <gst-plugin>) (name mchars) (rank unsigned-int) (func <gst-type-find-function>) (possible_caps <gst-caps>) (data <gpointer>) (data_notify <g-destroy-notify>)   (ret bool) (extensions mchars)

Registers a new typefind function to be used for typefinding. After registering this function will be available for typefinding. This function is typically called during an element's plugin initialization.

plugin

A <gst-plugin>.

name

The name for registering

rank

The rank (or importance) of this typefind function

func

The <gst-type-find-function> to use

extensions

Optional extensions that could belong to this type

possible-caps

Optionally the caps that could be returned when typefinding succeeds

data

Optional user data. This user data must be available until the plugin is unloaded.

data-notify

a <g-destroy-notify> that will be called on data when the plugin is unloaded.

ret

TRUE on success, FALSE otherwise
