Does Deepstream support .png?

[johnminho]

I have a .png image, but when I run Deepstream-app with this image, I got an error

ERROR from pngparse0: Internal data stream error.
Debug info: gstbaseparse.c(3611): gst_base_parse_loop (): /GstPipeline:pipeline/GstBin:multi_src_bin/GstBin:src_sub_bin0/GstURIDecodeBin:src_elem/GstDecodeBin:decodebin0/GstPngParse:pngparse0:

Here is info of the image

  Duration: N/A, bitrate: N/A
    Stream #0:0: Video: png, rgb24(pc), 1280x960, 25 tbr, 25 tbn, 25 tbc

I know that some DS versions until now do not support YUV444 jpeg images, and not infor for .png images.

I using Docker container with DS6.0, TRT8.2. Thanks.

Try add the below item to [source0]

video-format=NV12

PNG is compressed from rgb data. Default hareware pipeline works on NV12, adding data conversion might work

@junshengy
After adding video-format=NV12, the error was same.
I have a workound: convert to jpeg image and the error is gone. But jpeg and .png is a little bit different.

Is there anyway to directly load .png image in Deepstream?

[junshengy]

Can you update to DS 6.2 ? I have tried png image on my version 6.2,It work normally.

Maybe some bugs in DS 6.0.

@junshengy
