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... | |
