Functions | |
| GstQuery * | gst_nvquery_batch_size_new (void) |
| Creates a new batch-size query, which can be used by elements to query the number of buffers in upstream elements' batched buffers. More... | |
| gboolean | gst_nvquery_is_batch_size (GstQuery *query) |
| 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, used by the elements responding to the batch size query. More... | |
| gboolean | gst_nvquery_batch_size_parse (GstQuery *query, guint *batch_size) |
| Parses batch size from a batch size query. More... | |
| GstQuery * | gst_nvquery_numStreams_size_new (void) |
| Creates a number of streams query, used by elements to query upstream the number of input sources. More... | |
| gboolean | gst_nvquery_is_numStreams_size (GstQuery *query) |
| Determines whether a query is a number-of-streams query. More... | |
| 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) |
| Parses the number of streams from a number of streams query. More... | |
| GstQuery * | gst_nvquery_preprocess_poolsize_new (guint gieid) |
| Creates a preprocess poolsize query, used by elements to query preprocess element for the size of buffer pool. More... | |
| gboolean | gst_nvquery_is_preprocess_poolsize (GstQuery *query) |
| Determines whether a query is a preprocess poolsize query. More... | |
| void | gst_nvquery_preprocess_poolsize_set (GstQuery *query, guint preprocess_poolsize) |
| Sets the preprocess poolsize as a reponse to query. More... | |
| gboolean | gst_nvquery_preprocess_poolsize_parse (GstQuery *query, guint *preprocess_poolsize) |

| gboolean | gst_nvquery_is_update_caps (GstQuery *query) |
| Checks if a query is update_caps query. More... | |
| void | gst_nvquery_parse_update_caps (GstQuery *query, guint *stream_index, const GValue *frame_rate) |
| Parses the update_caps query. More... | |
