Thermimage - convertflirVID, Warning messages: 1- in system2, 2- in file.remove

[gtatters]

hmm. I'm not sure. It works on my machine.

Could you provide more information on where you have the file stored, since the error looks like system2 is unable to write files to the location. This might be a windows problem since you need to keep the files in user locations where you have write permission. It also might be related to white space in your folder names, but I cannot tell since the since I do not know what path your system has.

Maybe ignore my SampleSEQ.seq file and just put your file on your home desktop and try from there. Please let me know if that works.

[shaktalerv]

thank for your reply

Could you provide more information on where you have the file stored
C:\Users\Rr\Documents\FLIR

I tried differents locations in my harddisc and others disc (C:, D:, E:)
now I proved
C:\Users\Rr\Desktop
setwd("C:/Users/Rr/Desktop")

same warning with the "SampleSEQ.seq" and my file in this location.

Note: My Windows account is Administrator.

[gtatters]

and you have installed ffmpeg?

[gtatters]

so, it's possible the problem was in how I detect OS of user and then call ffmpeg. I have added functionality to detect the OS and then call either 'ffmpeg" or "ffmpeg.exe", the latter being the windows version.

If you can re-install Thermimage from github, the updated functions should be in v 4.0.1 and I'd be happy to hear if they fixed the problem.

[shaktalerv]

and you have installed ffmpeg?
yes, in:
C:\ffmpeg and add FFmpeg to Windows Path, ffmpeg V4.2

If you can re-install Thermimage from github, the updated functions should be in v 4.0.1 and I'd be happy to hear if they fixed the problem.

same problem, I tried re installed pearl to W 64x (strawberry, ActivePerl. latest version) and ImageMagick. same Warning messages.

[gtatters]

can you post the precise error message again. My changes should have led to something new happening.

[gtatters]

next time you try, please set verbose = TRUE, and post the entire output

let me try it all out on a windows machine to troubleshoot. I'll get back with an answer once I figure it out. the error above should say "running command "ffmpeg.exe" not "ffmpeg" for a windows machine. I'll see if I can work out why, and update here. Might take me a day.

[gtatters]

making progress, but the problem is how windows handles system pipe commands and the perl scripts. Thermimage was designed for mac / unix environments, and so these windows issues pop up. I'm going to have to re-write the perl script to work with little endian more effectively between OSs. I managed to replicate most of your issues above on a windows 7 machine, so now I have a path forward. But other things have arisen that might delay a fix.

[gtatters]

So I think I have a working version now. Still v4.0.1 if you want to re-install and try again. I edited the perl script, and tried to simplify matters for myself in the future. I have tested on Windows 10, R 3.6.1. I had to remember how to add perl and ffmpeg to the path before I could get it all working.

I'll close the comment for now, but please respond if I have created new problems.

[shaktalerv]

I updated to v4.0.1
Same problem

convertflirVID(f, exiftoolpath="installed", perlpath="installed",

               outputfiletype="avi", outputfolder="output", verbose=T)
fff files merged into thermalvid.raw file in temp folder. 


Break thermalvid.raw video into separate files in temp folder:
perl.exe  -f C:/Users/Rr/Documents/R/win-library/3.6/Thermimage/perl/split_tiff.pl < temp/thermalvid.raw

i don't think the update is taking effect. I made changes to the output so I could keep track of error messages, and the text above is from 4.0.0. Are you removing the old package and then installing using devtools::install_github("gtatters/Thermimage")?

Alternatively, could you consider downloading the convertflirVID.R function from here, https://github.com/gtatters/Thermimage/blob/master/R/convertflirVID.R, rename it to convertflirVID2 locally, place into your local environment (i.e. run the function to save to memory), and see if your code above works in place of the one in the package?

[gtatters]

another idea is could you run the following from your Rstudio environment and tell me what the output is:

Sys.info()["sysname"]

I am assuming it is "Windows" but maybe I've made an assumption about different OS.

[shaktalerv]

reinstalled v4.0.1. (devtools::install_github("gtatters/Thermimage"))

output png

1st stage completed.

Thanks a lot!

[shaktalerv]

I am assuming it is "Windows" but maybe I've made an assumption about different OS.

Sys.info () ['sysname']
sysname
"Windows"

[gtatters]

excellent!! Phew. Hope it stops giving you grief. I guess the package didn't fully install/overwrite the older version.
