The low limit of Encoder and Decoder supported resolution


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?

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.
