int32_t | appGstInit (app_codec_wrapper_params_t *prm) |
Launches the GstPipeline described by user defined parameters. Initializes the gst_wrapper and calls gst_parse_launch() on the command string. More... | |
int32_t | appGstSrcInit (void *data_ptr[CODEC_MAX_BUFFER_DEPTH][CODEC_MAX_NUM_CHANNELS][CODEC_MAX_NUM_PLANES]) |
Initializes the AppSrc elements to be able to push buffers to the GstPipeline. Wraps the given allocated memory as GstBuffers to push. The input parameters (in_*) must be properly initialised. More... | |
int32_t | appGstSinkInit (void *(*data_ptr)[CODEC_MAX_NUM_CHANNELS][CODEC_MAX_NUM_PLANES]) |
Initializes the AppSink elements to be able to pull buffers from the GstPipeline. Registers the data_pointers that will map to the bufferpool of pulled GstBuffers. The output parameters (out_*) must be properly initialised. More... | |
int32_t | appGstStart () |
Starts the GstPipeline that was launched previously. More... | |
int32_t | appGstEnqAppSrc (uint8_t idx) |
Push a buffer from the bufferpool to the AppSrc element. More... | |
int32_t | appGstDeqAppSrc (uint8_t idx) |
Wait for a previously pushed buffer to be consumed by the GstPipeline. More... | |
int32_t | appGstEnqEosAppSrc () |
Push EOS (End Of Stream) to the AppSrc element. Signals the elements to stop processing buffers after this. More... | |
int32_t | appGstDeqAppSink (uint8_t idx) |
Pull a buffer from the AppSink element into the bufferpool. More... | |
int32_t | appGstEnqAppSink (uint8_t idx) |
Release a previously pulled GstBuffer back to GStreamer and cleanup. More... | |
int32_t | appGstStop () |
Stops the GstPipeline that was in playing state. If there is no AppSink element, waits to recieve EOS before cleaning up. More... | |
void | appGstDeInit () |
Unmaps all buffers that were mapped and destroys all GStreamer objects. More... | |
void | appGstPrintStats () |
Prints the current count of the numbers of buffers pushed/pulled to/from the GstPipeline. Not multi-thread safe. More... | |
