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...

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.

Is there any way to send data to GPU for decoding, other than web cam? I do not have Raspi camera.

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...

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 ! ...

Hi Richard, This is the command i am running from pi connected via ssh. pi@raspberrypi ~ $ gst-launch-1.0 v4l2src device=/dev/video0 ! omxh264enc ! "video/x-h264,profile=high" ! h264parse ! queue max-size-bytes=10000000 ! matroskamux ! filesink location=test.mkv Data type - /x-h264, width ...

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 ! ...

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.

Hi, I have Logitech, Inc. Webcam Pro 9000. And able to capture image, video capturing by uvccapture motion softwares. Help me to do the below tasks... (I am new to this, expect step by step procedure would help for faster result) 1. How do i send raw data from camera to pi for encoding? 2. Decoding ...

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
