I’m using deepstream-app, deepstream-test4-app and different derivatives from those.
When I process a “normal” h264 file, 16:9 ratio, 1920x1080, it works great.
This is the mediainfo output for such file:
General
Complete name : una.h264
Format : AVC
Format/Info : Advanced Video Codec
File size : 38.6 MiB

Format : AVC
Format/Info : Advanced Video Codec
Format profile : Baseline@L4
Format settings : 1 Ref Frames
Format settings, CABAC : No
Format settings, ReFrames : 1 frame
Format settings, GOP : M=1, N=30
Width : 1 920 pixels
Height : 1 080 pixels
Display aspect ratio : 16:9
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive
But what I have to process is a wider image, which is a stitch from 3 cameras, resulting in a 3840x720 image.
This is the mediainfo output of such file:
General
Complete name : ../filename.h264
Format : AVC
Format/Info : Advanced Video Codec
File size : 103 MiB

Format : AVC
Format/Info : Advanced Video Codec
Format profile : Baseline@L5

Format settings, GOP : M=1, N=30
Width : 3 840 pixels
Height : 720 pixels
Display aspect ratio : 5.333
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive
Both files are similar in quality, resolution, etc. And composed of the same features.
But in the second case the inference is really poor. It only detects a couple of the bigger persons and nothing more. There are about 10-15 persons on the image, which are perfectly detected on the single image test.
So I guess my question here is: What do I have to tune in the inference config files in order to detect ok on the wider image? That am I doing wrong?
Thanks a lot.
