Core errors are errors inside the core GStreamer library.
GST_CORE_ERROR_FAILED |
a general error which doesn't fit in any other category. Make sure you add a custom message to the error call. |
GST_CORE_ERROR_TOO_LAZY |
do not use this except as a placeholder for deciding where to go while developing code. |
GST_CORE_ERROR_NOT_IMPLEMENTED |
use this when you do not want to implement this functionality yet. |
GST_CORE_ERROR_STATE_CHANGE |
used for state change errors. |
GST_CORE_ERROR_PAD |
used for pad-related errors. |
GST_CORE_ERROR_THREAD |
used for thread-related errors. |
GST_CORE_ERROR_SCHEDULER |
used for scheduler-related errors. |
GST_CORE_ERROR_NEGOTIATION |
used for negotiation-related errors. |
GST_CORE_ERROR_EVENT |
used for event-related errors. |
GST_CORE_ERROR_SEEK |
used for seek-related errors. |
GST_CORE_ERROR_CAPS |
used for caps-related errors. |
GST_CORE_ERROR_TAG |
used for negotiation-related errors. |
GST_CORE_ERROR_NUM_ERRORS |
the number of core error types. |
typedef enum { GST_LIBRARY_ERROR_FAILED = 1, GST_LIBRARY_ERROR_TOO_LAZY, GST_LIBRARY_ERROR_INIT, GST_LIBRARY_ERROR_SHUTDOWN, GST_LIBRARY_ERROR_SETTINGS, GST_LIBRARY_ERROR_ENCODE, GST_LIBRARY_ERROR_NUM_ERRORS } GstLibraryError;
Library errors are for errors from the library being used by elements (initializing, finalizing, settings, ...)
GST_LIBRARY_ERROR_FAILED |
a general error which doesn't fit in any other category. Make sure you add a custom message to the error call. |
GST_LIBRARY_ERROR_TOO_LAZY |
do not use this except as a placeholder for deciding where to go while developing code. |
GST_LIBRARY_ERROR_INIT |
used when the library could not be opened. |
GST_LIBRARY_ERROR_SHUTDOWN |
used when the library could not be closed. |
GST_LIBRARY_ERROR_SETTINGS |
used when the library doesn't accept settings. |
GST_LIBRARY_ERROR_ENCODE |
used when the library generated an encoding error. |
GST_LIBRARY_ERROR_NUM_ERRORS |
the number of library error types. |

Resource errors are for any resource used by an element: memory, files, network connections, process space, ... They're typically used by source and sink elements.
GST_RESOURCE_ERROR_FAILED |
a general error which doesn't fit in any other category. Make sure you add a custom message to the error call. |
GST_RESOURCE_ERROR_TOO_LAZY |
do not use this except as a placeholder for deciding where to go while developing code. |
GST_RESOURCE_ERROR_NOT_FOUND |
used when the resource could not be found. |
GST_RESOURCE_ERROR_BUSY |
used when resource is busy. |
GST_RESOURCE_ERROR_OPEN_READ |
used when resource fails to open for reading. |
GST_RESOURCE_ERROR_OPEN_WRITE |
used when resource fails to open for writing. |
GST_RESOURCE_ERROR_OPEN_READ_WRITE |
used when resource cannot be opened for both reading and writing, or either (but unspecified which). |
GST_RESOURCE_ERROR_CLOSE |
used when the resource can't be closed. |
GST_RESOURCE_ERROR_READ |
used when the resource can't be read from. |
GST_RESOURCE_ERROR_WRITE |
used when the resource can't be written to. |
GST_RESOURCE_ERROR_SEEK |
used when a seek on the resource fails. |
GST_RESOURCE_ERROR_SYNC |
used when a synchronize on the resource fails. |
GST_RESOURCE_ERROR_SETTINGS |
used when settings can't be manipulated on |
GST_RESOURCE_ERROR_NUM_ERRORS |
the number of library error types. |

Stream errors are for anything related to the stream being processed: format errors, media type errors, ... They're typically used by decoders, demuxers, converters, ...
GST_STREAM_ERROR_FAILED |
a general error which doesn't fit in any other category. Make sure you add a custom message to the error call. |
GST_STREAM_ERROR_TOO_LAZY |
do not use this except as a placeholder for deciding where to go while developing code. |
GST_STREAM_ERROR_NOT_IMPLEMENTED |
use this when you do not want to implement this functionality yet. |
GST_STREAM_ERROR_TYPE_NOT_FOUND |
used when the element doesn't know the stream's type. |
GST_STREAM_ERROR_WRONG_TYPE |
used when the element doesn't handle this type of stream. |
GST_STREAM_ERROR_CODEC_NOT_FOUND |
used when there's no codec to handle the stream's type. |
GST_STREAM_ERROR_DECODE |
used when decoding fails. |
GST_STREAM_ERROR_ENCODE |
used when encoding fails. |
GST_STREAM_ERROR_DEMUX |
used when demuxing fails. |

#define GST_ERROR_SYSTEM ("system error: %s", g_strerror (errno))
Generates an human readable error message out of an errno number.
gchar* gst_error_get_message (GQuark domain, gint code);
domain : |
the GStreamer error domain this error belongs to. |
code : |
the error code belonging to the domain. |
Returns : | a newly allocated string describing the error message in the current locale. |
