MMAL Reziser input sets to opaque
Posted: Thu Oct 25, 2018 12:52 pm
Is possible to set the resizer input encoding to opaque?

Is another output of splitter used? Based on that pipe I fail to see why you need either splitter or resize - you may as well ask for your desired resolution out of the camera and feed it direct to video_encode.longo92 wrote: ↑Thu Oct 25, 2018 1:27 pmI mean "vc.ril.resize". Also can i set the output to the opaque and tunnel to the mmal vidoe encoder? I'm using the firmware of 25 May 2018, it's safe to use or shall i update to eliminate possible bugs?
I have a simple application where a camera is tunneled to a splitter, the splitter tunneled to a resizer and the resizer tunneled to an encoder:
I want use opaque encoding and zero-copy for maximum performance.
Everything has limitations.
I haven't added any option for resizing at the front end of video_encode, although in theory it would be possible.longo92 wrote:When yuoi said that now the encoder uses isp for conversion, it means that can it can perform resizing inside (also format conversion)? So there is no need to tunnel isp->encoder?
