Bear with me if this is a known issue, it's been 5 years since I last looked at OpenMAX IL. Not sure if my ex-colleagues Diego and Giulio are still in the loop. I am trying to quantify the overhead due to gst-openmax, compared to plain old existing gstreamer elements. On an Atom/Ubuntu platform in ST/GV3off, I get the following residencies: madplay: 13% C0 gst-launch filesrc ! mad ! audioconvert ! alsasink: 16% C0 (fine) gst-launch filesrc ! omx_mp3dec ! omx_audiosink: 63% C0 (not good) Any idea what's happening? All the three configurations rely on the same libmad and the same test file. Thanks for your help Pierre |
