Functions | |
GstQuery * | gst_nvquery_batch_size_new (void) |

Determines whether a query is a batch size query. More... | |
void | gst_nvquery_batch_size_set (GstQuery *query, guint batch_size) |
Sets the batch size, which is used by the elements responding to the batch size query. More... | |
gboolean | gst_nvquery_batch_size_parse (GstQuery *query, guint *batch_size) |
Parses the batch size from a batch size query. More... | |
GstQuery * | gst_nvquery_numStreams_size_new (void) |

void | gst_nvquery_numStreams_size_set (GstQuery *query, guint numStreams_size) |
Sets the number of input sources. More... | |
gboolean | gst_nvquery_numStreams_size_parse (GstQuery *query, guint *numStreams_size) |

GstQuery* gst_nvquery_batch_size_new | ( | void | ) |
Creates a new batch-size query, which can be used by elements to query upstream the number of buffers in the batched buffer.
gboolean gst_nvquery_batch_size_parse | ( | GstQuery * | query, |
guint * | batch_size | ||
) |
Parses the batch size from a batch size query.
params[in] query A batch size GstQuery
. params[out] batch_size A pointer to an unsigned integer in which the function will places the batch size.
return A boolean indicating whether the query was successfully parsed.
void gst_nvquery_batch_size_set | ( | GstQuery * | query, |
guint | batch_size | ||
) |
Sets the batch size, which is used by the elements responding to the batch size query.
This function fails if the query is not a batch size query.
params[in] query A batch size GstQuery
. params[in] batch_size The batch size to be set.
gboolean gst_nvquery_is_batch_size | ( | GstQuery * | query | ) |
Determines whether a query is a batch size query.
params[in] query The GstQuery
to be checked.
gboolean gst_nvquery_is_numStreams_size | ( | GstQuery * | query | ) |
Determines whether a query is a number of streams query.
params[in] query The GstQuery
to be checked.
GstQuery* gst_nvquery_numStreams_size_new | ( | void | ) |
Creates a number of streams query, which can be used by elements to query upstream the number of input sources.
gboolean gst_nvquery_numStreams_size_parse | ( | GstQuery * | query, |
guint * | numStreams_size | ||
) |
Parses the number of streams from a number of streams query.
params[in] query A number of streams GstQuery
. params[out] batch_size A pointer to an unsigned integer in which the function is to place the number of streams.
return A boolean indicating if the query was successfully parsed.
void gst_nvquery_numStreams_size_set | ( | GstQuery * | query, |
guint | numStreams_size | ||
) |
Sets the number of input sources.
This is used by the elements responding to a number of streams query. The function fails if the query is not of the correct type.
params[in] query A number of streams GstQuery
. params[in] numStreams_size The number of input sources.
