Optimized v4l2src gstreamer plugin for I.MX8

nissim_beja — Sun, 19 Jan 2020 08:11:31 GMT

Dear All,

Is there an optimized v4l2src gstreamer plugin, that utilizes the I.MX8 hardware blocks like DMA component (to reduce video pipeline latency) for the I.MX8 processors? if not, is there any plan to provide such in the future?

I found that there is such plugin for the I.MX6 (imxv4l2video).

Thanks,

Nissim.

Hi Nissim

MX8 specific plugins are listed in Table 15. i.MX GStreamer 1.0 plugins

attached Release Notes. Example with v4l2src :

gst-launch-1.0 v4l2src ! video/x-raw,width=640,height=480 ! \
v4l2h264enc extra-controls="controls,h264_entropy_mode=0,video_bitrate=245000;" ! \
h264parse ! v4l2h264dec ! queue ! waylandsink sync=false

Best regards

Hi Igor,

Does it mean that the I.MX8 uses the standard v4l2src plugin?

if its true are there plans to provide such plugin that utilizes the hardware of the I.MX8 Processor (like in I.MX6)?
