AM62A3: Can AM62A3 support HW H264 codec 4K ENCODE /DECODE at the same time?

Hi Daniel,

You should be able to decode and encode H.264 4K@30fps easily on AM62Ax.

Also please see section 3.7.11 in the below link to increase the cma in order to have 4k decode and encode working together.

https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/08_06_00_45/exports/docs/linux/Foundational_Components_Multimedia_wave5.html

In my case, I increased the cma to 1000M and was able to run this pipeline successfully:

gst-launch-1.0 -v filesrc location=jellyfish-4k30-h264.mkv ! matroskademux ! h264parse ! v4l2h264dec capture-io-mode=4 ! v4l2h264enc output-io-mode=5 ! filesink location=jellyfish.264

Hope this helps.

Hi Suren

The Encode/Decode application will need Real-Time.

(it will be similar to the following application, which is to receive and send video streaming at the same time)

Video Streaming use-caseServer (imx219 rawcamera->isp->encode->streamout) :   target $gst-launch-1.0 v4l2src device=/dev/video2 io-mode=dmabuf ! video/x-bayer,width=1920,height=1080, framerate=30/1, format=bggr ! tiovxisp sensor-name=SENSOR_SONY_IMX219_RPI dcc-isp-file=/opt/imaging/imx219/dcc_viss.bin sink_0::dcc-2a-file=/opt/imaging/imx219/dcc_2a.bin sink_0::device=/dev/v4l-subdev2 ! video/x-raw,format=NV12 ! v4l2h264enc output-io-mode=dmabuf-import extra-controls="controls,h264_i_frame_period=60" ! rtph264pay ! udpsink port=5000 host=<ip_address> Client (streamin->decode->display :   target $gst-launch-1.0 -v udpsrc port=5000 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtpjitterbuffer latency=50 ! rtph264depay ! h264parse ! v4l2h264dec capture-io-mode=dmabuf ! queue ! fpsdisplaysink text-overlay=false name=fpssink video-sink="kmssink driver-name=tidss sync=true show-preroll-frame=false" sync=true -v

However, it is mentioned in the document that depending on the resolution, not all can be Real Time

Our goal is to achieve at least 1080p30 Encode/Decode Real-Time

Will AM62A3 meet my goals?

Thanks

Daniel

Hi Daniel,

Video Streaming is possible on AM62A3. 4k@30fps encoding and decoding is possible as I mentioned earlier, so streaming should also be possible, provided camera sensor can throw 4K data.

1080p30 streaming (Encode + Decode) is definitely possible in real-time.

Hope this helps.
