To extract metadata it's possible to use the RidgeRun Gstreamer element seiextract. Once you have the pipeline with a seiextract element it is going to take the metadata in the h264 buffer and add it as a GstMeta to the output buffer. Also includes a signal property for the metadata message. | To extract metadata it's possible to use the RidgeRun Gstreamer element seiextract.
