Detailed Description

 This section documents all error codes used in the GPAC framework. Most of the GPAC's functions will use these as

return values, and some of these errors are also used for state communication with the different modules of the framework.

Enumeration Type Documentation

enum GF_Err

GPAC Error

 positive values are warning and info, 0 means no error and negative values are errors

Enumerator
GF_SCRIPT_INFO	Message from any scripting engine used in the presentation (ECMAScript, MPEG-J, ...) (Info).
GF_PACKED_FRAMES	Indicates an data frame has several AU packed (not MPEG-4 compliant). This is used by decoders to force multiple decoding of the same data frame (Info).
GF_EOS	Indicates the end of a stream or of a file (Info).
GF_OK	Operation success (no error).
GF_BAD_PARAM	One of the input parameter is not correct or cannot be used in the current operating mode of the framework.
GF_OUT_OF_MEM	Memory allocation failure.
GF_IO_ERR	Input/Output failure (disk access, system call failures)
GF_NOT_SUPPORTED	The desired feature or operation is not supported by the framework
GF_CORRUPTED_DATA	Input data has been corrupted
GF_SG_UNKNOWN_NODE	A modification was attempted on a scene node which could not be found
GF_SG_INVALID_PROTO	The PROTO node interface does not match the nodes using it
GF_SCRIPT_ERROR	An error occured in the scripting engine
GF_BUFFER_TOO_SMALL	Buffer is too small to contain decoded data. Decoders shall use this error whenever they need to resize their output memory buffers
GF_NON_COMPLIANT_BITSTREAM	Bitstream is not compliant to the specfication it refers to
GF_CODEC_NOT_FOUND	No decoders could be found to handle the desired media type
GF_URL_ERROR	The URL is not properly formatted or cannot be found
GF_SERVICE_ERROR	An service error has occured at the local side
GF_REMOTE_SERVICE_ERROR	A service error has occured at the remote (server) side
GF_STREAM_NOT_FOUND	The desired stream could not be found in the service
GF_ISOM_INVALID_FILE	The IsoMedia file is not a valid one
GF_ISOM_INCOMPLETE_FILE	The IsoMedia file is not complete. Either the file is being downloaded, or it has been truncated
GF_ISOM_INVALID_MEDIA	The media in this IsoMedia track is not valid (usually due to a broken stream description)
GF_ISOM_INVALID_MODE	The requested operation cannot happen in the current opening mode of the IsoMedia file
GF_ISOM_UNKNOWN_DATA_REF	This IsoMedia track refers to media outside the file in an unknown way
GF_ODF_INVALID_DESCRIPTOR	An invalid MPEG-4 Object Descriptor was found
GF_ODF_FORBIDDEN_DESCRIPTOR	An MPEG-4 Object Descriptor was found or added to a forbidden descriptor
GF_ODF_INVALID_COMMAND	An invalid MPEG-4 BIFS command was detected
GF_BIFS_UNKNOWN_VERSION	The scene has been encoded using an unknown BIFS version
GF_IP_ADDRESS_NOT_FOUND	The remote IP address could not be solved
GF_IP_CONNECTION_FAILURE	The connection to the remote peer has failed
GF_IP_NETWORK_FAILURE	The network operation has failed
GF_IP_CONNECTION_CLOSED	The network connection has been closed
GF_IP_NETWORK_EMPTY	The network operation has failed because no data is available
GF_IP_SOCK_WOULD_BLOCK	The network operation has been discarded because it would be a blocking one
GF_IP_UDP_TIMEOUT	UDP connection did not receive any data at all. Signaled by client services to reconfigure network if possible
GF_AUTHENTICATION_FAILURE	Authentication with the remote host has failed
GF_SCRIPT_NOT_READY	Script not ready for playback
GF_INVALID_CONFIGURATION	Bad configuration for the current contex
GF_NOT_FOUND	The element has not been found
GF_MISSING_REQUIREMENTS	The filter is missing at least one requirement
GF_WRONG_DATAFORMAT	Unexpected format of data
