Member Function Documentation

nsresult sbDeviceTranscoding::FindTranscodeProfile ( sbIMediaItem *  aMediaItem,
sbITranscodeProfile **  aProfile,
CompatibilityType *  aDeviceCompatibility 
)

Returns the profile for the given media item

Parameters
aMediaItemThe media item to find the profile for
aProfilethe profile found or may be null if no transcoding is needed.
aDeviceCompatibilityWhether this item is supported directly by the device, or if transcoding is needed. Will be set even if no profile is found.
Note
NS_ERROR_NOT_AVAILABLE is returned if no suitable profile is found but transcoding is needed

Here is the caller graph for this function:

nsresult sbDeviceTranscoding::PrepareBatchForTranscoding ( Batch &  aBatch)

aBatch The batch to process

Prepare a batch for transcoding. This processes items in the batch and determines which of them require transcoding and/or album-art transcoding.

Process a batch in preparation for transcoding, figuring out which items need transcoding.

Here is the call graph for this function:

nsresult sbDeviceTranscoding::SelectTranscodeProfile ( PRUint32  aTranscodeType,
sbITranscodeProfile **  aProfile 
)

Select a transcode profile to use when transcoding to this device.

Parameters
aTranscodeTypeThe type of transcoding profile to look for.
aProfileThe profile found or may be null if no transcoding is needed.
Note
This selects the best available transcoding profile for this device for arbitrary input - even if the thing to be transcoded is directly supported by the device.
NS_ERROR_NOT_AVAILABLE is returned if no suitable profile is found

nsIURI **  aTranscodedDestinationURI = nsnull 
)

Transcode a media item to the destination specified by aDestinationURI. If aTranscodedDestinationURI is not null, return the final destination URI with transcoded file extension in aTranscodedDestinationURI.
