void vlc_thumbnailer_Cancel | ( | vlc_thumbnailer_t * | thumbnailer, |
vlc_thumbnailer_request_t * | request | ||
) |
vlc_thumbnailer_Cancel Cancel a thumbnail request
thumbnailer | A thumbnailer object |
request | An opaque thumbnail request object |
Cancelling a request will not invoke the completion callback. The behavior is undefined if the request is cancelled after its completion.

vlc_thumbnailer_RequestByTime Requests a thumbnailer at a given time
thumbnailer | A thumbnailer object |
pos | The position at which the thumbnail should be taken |
speed | The seeking speed |
input_item | The input item to generate the thumbnail for |
timeout | A timeout value, or VLC_TICK_INVALID to disable timeout |
cb | A user callback to be called on completion (success & error) |
user_data | An opaque value, provided as pf_cb's first parameter |
If this function returns a valid request object, the callback is guaranteed to be called, even in case of later failure. The returned request object must not be used after the callback has been invoked. That request object is owned by the thumbnailer, and must not be released. The provided input_item will be held by the thumbnailer and can safely be released after calling this function.
