The low limit of Encoder and Decoder supported resolution

Hi,

What is the genuine lowest resolution of the Encoder and Decoder supported? In H264 and H265?

I saw (144,144) is the lowest in the printed info. However, I tried to encode (176,96), it worked.

Do height and width have their own limitation? Or there is some limitations like macroblocks?

Hi,
We verify the standard resolutions such as 640x480, 1280x720, … May not focus on small-resolution cases. Please try the resolution with videotestsrc:

$ gst-launch-1.0 videotestsrc num-buffers=300 ! video/x-raw,width=176,height=144 ! nvvidconv ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=a.mp4

176x144 is a valid resolution. If you need the smalled resolution, please replace the setting and give it a try.
