Re: Raw data encoding and decoding through GPU on Raspberry
Hi ghans, 1. How do i make sure that encoding is happening through GPU? Any command like "top" for CPU usage. 2. The below gstreamer command i optimized for low resolution 320x240, 10fps with CPU load 9.4%. screen-shot : pi@raspberrypi ~ $ gst-launch-1.0 v4l2src device=/dev/video0 ! omxh26...

Re: Raw data encoding and decoding through GPU on Raspberry
Hi Jamesh,
I understood that without Raspi cam, encoding/decoding on GPU core not supported.
What is the possible way to use GPU for processing of data? I can't buy a raspi cam now.

Re: Raw data encoding and decoding through GPU on Raspberry
Is there any way to send data to GPU for decoding, other than web cam? I do not have Raspi camera.

Re: Raw data encoding and decoding through GPU on Raspberry
Hi Jamesh, My interest here is to check encoding/decoding of h.264/raw data through hardware acceleration. I understood from forum posts, g-streamer + openMAX uses GPU core for encoding. Am i correct? Currently i am getting raw data from web cam connected to pi and using g-streamer for streaming and...

Raw data encoding and decoding through GPU on Raspberry pi
Hi Dom/JamesH How to check encoding is happening through H/W acceleration? when i run this command from pi connected through ssh, using pre-built binaries of gstreamer1.0. pi@raspberrypi ~ $ gst-launch-1.0 v4l2src device=/dev/video0 ! omxh264enc ! "video/x-h264,profile=high" ! h264parse ! ...

CPU occupancy during hardware encoding
Hi, I am running below commands to encode data from web cam using hardware acceleration. I observed almost 93% CPU occupancy. pi@raspberrypi ~ $ gst-launch-1.0 v4l2src device=/dev/video0 ! omxh264enc ! "video/x-h264,profile=high" ! h264parse ! queue max-size-bytes=10000000 ! matroskamux ! ...

Re: How to stream raw data to the Raspberry Pi for encoding
Hi jbeale,
Thanks for your reply.
I have code for implementing RFC 3984 H.264 frames over RTP/IP/Ethernet. For the time-being, what procedure to be followed to do encoding/decoding through ffmpeg?
Later will concentrate on real-time encoding/decoding.

How to stream raw data to the Raspberry Pi for encoding ?
Hi,
I have Raspberry pi booted using NOOBS software with OS Raspbian.
I want to test the following without using camera.
1. Streaming raw data to Raspberry pi to encode
2. Decoding of h264 and M-JPEG video formats on pi
Thanks,
Anita
