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 : [email protected] ~ $ gst-launch-1.0 v4l2src device=/dev/video0 ! omxh264enc ! "vi...

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...

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
