Got stream-status message
Opening in BLOCKING MODE
NvMMLiteOpen : Block : BlockType = 277
NVMEDIA: Reading vendor.tegra.display-size : status: 6
NvMMLiteBlockCreate : Block : BlockType = 277

what does this mean ?? why pipeline prints this after every 30 images ??

Hi,
These are the prints to show decoding instance is created. Generally we will see it in beginning of playing a video file. It seems strange if you see it keep printing. Probably the h264 stream changes resolution every 30 frames.

oh okay. thanks!

yes, I checked. I’m using images which have different size. does it cause overhead ?
if I make the size of all the images equal, will it give perf boost ?

HI,
If the h264 steam does not change resolutions dynamically, it will not destroy and re-create decoding instance in runtime. This should have better performance.

Besides, there is option for enabling maximum performance in decoder. Please also enable it.

okay,thanks!!
