Functions
int32_t	appCodecInit (app_codec_wrapper_params_t *prm)
	Launches the CODECPipeline described by user defined parameters. Initializes the codec_wrapper and calls gst_parse_launch() on the command string. More...
int32_t	appCodecSrcInit (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 CODECPipeline. Wraps the given allocated memory as CODECBuffers to push. The input parameters (in_*) must be properly initialised. More...
int32_t	appCodecSinkInit (void *data_ptr[CODEC_MAX_BUFFER_DEPTH][CODEC_MAX_NUM_CHANNELS][CODEC_MAX_NUM_PLANES])
	Initializes the AppSink elements to be able to pull buffers from the CODECPipeline. Registers the data_pointers that will map to the bufferpool of pulled CODECBuffers. The output parameters (out_*) must be properly initialised. More...
int32_t	appCodecStart ()
	Starts the CODECPipeline that was launched previously. More...
int32_t	appCodecEnqAppSrc (uint8_t idx)
	Push a buffer from the bufferpool to the AppSrc element. More...
int32_t	appCodecDeqAppSrc (uint8_t idx)
	Wait for a previously pushed buffer to be consumed by the CODECPipeline. More...
int32_t	appCodecEnqEosAppSrc ()
	Push EOS (End Of Stream) to the AppSrc element. Signals the elements to stop processing buffers after this. More...
int32_t	appCodecDeqAppSink (uint8_t idx)
	Pull a buffer from the AppSink element into the bufferpool. More...
int32_t	appCodecEnqAppSink (uint8_t idx)
	Release a previously pulled CODECBuffer back to GStreamer and cleanup. More...
int32_t	appCodecStop ()
	Stops the CODECPipeline that was in playing state. If there is no AppSink element, waits to recieve EOS before cleaning up. More...
void	appCodecDeInit ()
	Unmaps all buffers that were mapped and destroys all GStreamer or OpenMAX objects. More...
void	appCodecPrintStats ()
	Prints the current count of the numbers of buffers pushed/pulled to/from the CODECPipeline. Not multi-thread safe. More...
