Member Function Documentation

◆ DetectAndAddMissingItemData()

void CVideoThumbLoader::DetectAndAddMissingItemData ( CFileItem & item )

protected

Tries to detect missing data/info from a file and adds those.

Parameters

item	The CFileItem to process

Returns: void

Todo:: in case of too many false positives due to using the full path, extract the filename only using string utils

◆ FillLibraryArt()

bool CVideoThumbLoader::FillLibraryArt ( CFileItem & item )

overridevirtual

helper function to fill the art for a video library item

Parameters

item	a video CFileItem

Returns: true if we fill art, false otherwise

Todo:: Is m_artist set other than musicvideo? Remove this fallback if not.

Reimplemented from CThumbLoader.

◆ FillThumb()

bool CVideoThumbLoader::FillThumb ( CFileItem & item )

virtual

Fill the thumb of a video item First uses a cached thumb from a previous run, then checks for a local thumb and caches it for the next run.

Parameters

item	the CFileItem object to fill

Returns: true if we fill the thumb, false otherwise

◆ GetArtFromCache()

const ArtMap & CVideoThumbLoader::GetArtFromCache	(	const std::string &	mediaType,
		const int	id
	)

protected

◆ GetArtTypes()

std::vector< std::string > CVideoThumbLoader::GetArtTypes ( const std::string & type )

static

return the available art types for a given media type

Parameters

type	the type of media.

Returns: a vector of art types.

See also: GetLocalArt

◆ GetEmbeddedThumb()

bool CVideoThumbLoader::GetEmbeddedThumb	(	const std::string &	path,
		const std::string &	type,
		EmbeddedArt &	art
	)

static

◆ GetEmbeddedThumbURL()

std::string CVideoThumbLoader::GetEmbeddedThumbURL ( const CFileItem & item )

static

helper function to retrieve a thumb URL for embedded video thumbs

Parameters

item	a video CFileItem.

Returns: a URL for the embedded thumb.

◆ GetLocalArt()

std::string CVideoThumbLoader::GetLocalArt	(	const CFileItem &	item,
		const std::string &	type,
		bool	checkFolder = `false`
	)

static

Find a particular art type for a given item, optionally checking at the folder level.

Parameters

item	the CFileItem to search.
type	the type of art to look for.
checkFolder	whether to also check the folder level for files. Defaults to false.

Returns: the art file (if found), else empty.

◆ IsArtTypeInWhitelist()

bool CVideoThumbLoader::IsArtTypeInWhitelist	(	const std::string &	artType,
		const std::vector< std::string > &	whitelist,
		bool	exact
	)

static

◆ IsValidArtType()

bool CVideoThumbLoader::IsValidArtType ( const std::string & potentialArtType )

static

◆ LoadItem()

bool CVideoThumbLoader::LoadItem ( CFileItem * pItem )

overridevirtual

Look for a thumbnail for pItem. If one does not exist, look for an autogenerated thumbnail. If that does not exist, attempt to autogenerate one. Finally, check for the existence of fanart and set properties accordingly.

Returns: : true if pItem has been modified

Reimplemented from CBackgroundInfoLoader.

◆ LoadItemCached()

bool CVideoThumbLoader::LoadItemCached ( CFileItem * pItem )

overridevirtual

Reimplemented from CBackgroundInfoLoader.

		bool	success,
		CJob *	job
	)

overridevirtual

Callback from CThumbExtractor on completion of a generated image.

Performs the callbacks and updates the GUI.

See also: CImageLoader, IJobCallback

void CVideoThumbLoader::OnLoaderFinish ( )

overridevirtual

Reimplemented from CThumbLoader.

◆ OnLoaderStart()

void CVideoThumbLoader::OnLoaderStart ( )

overridevirtual

Reimplemented from CThumbLoader.
