How to convert .arf file into .mp4 or any other playable format? I went through this link
This was fine until I got this:
Converting {path to arf} to {destination}
Retrieving video data, fps=4...
At the destination no converted file appeared.

I am using Adobe Extract PDF and it works fine. I only have 1 problem when I try to save the result file:
result.save_as("./output/ExtractTextInfoFromPDF.zip")
Meaning that I am saving the file in Dir /output at root of current python app
Adobe's API responds with an OSError: [WinError 17] stating that temp file stored at AppData\Local\Temp\extractSdkResult\5b6dd24443b011ed9c77010101010000.zip cannot be moved to my local Dir on drive E:
What should I do ?
Thanks a lot,

I am trying to download and unzip a folder of files from GitHub into R. I can manually download the file at https://github.com/dylangomes/SO/blob/main/Shape.zip and then extract all files in working directory, but I'd like to work directly from R.
utils::unzip("https://github.com/dylangomes/SO/blob/main/Shape.zip")
# Warning message:
# In utils::unzip("https://github.com/dylangomes/SO/blob/main/Shape.zip", :
# error 1 in extracting from zip file
It says it is a warning message, although nothing has been downloaded or unzipped into my wd.
I can download the file to my machine:
utils::download.file("https://github.com/dylangomes/SO/blob/main/Shape.zip")
But I get the same message with the unzip function:
utils::unzip("Shape.zip")
And the downloaded file cannot manually be extracted. Here, I get the error that the compressed folder is empty. The unzip line works on the manually downloaded .zip file, which tells me something is wrong with the download.file line.
So if I add raw=TRUE to the end (which can make a difference in downloading data from GitHub):
utils::download.file("https://github.com/dylangomes/SO/blob/main/Shape.zip?raw=TRUE","Shape.zip")
utils::unzip("Shape.zip")
I get a different warning with, similarly, nothing being executed:
Warning message:
In utils::unzip("Shape.zip") : internal error in 'unz' code
I have tried most of the answers at Using R to download zipped data file, extract, and import data, but they appear to be for single files that are zipped and aren't helping here. I've tried the answers at r function unzip error 1 in extracting from zip file, which mentions the same warning message I am getting, but none of the solutions work in this case.
Any idea of what I am doing wrong?
You need to use:
download.file(
"https://github.com/dylangomes/SO/blob/main/Shape.zip?raw=TRUE",
"Shape.zip",
mode = "wb"
)
Without the query string ?raw=TRUE you are downloading the webpage and not the file.
(For Windows) R will use mode = "wb" by default when it detects from the end of the URL that certain file formats, including .zip, are being downloaded. However, the URL finishing with a query string instead of a file format means the check fails so you need to set the mode explicitly.
I'm trying to download the xlsx file that is available at the following url. If you go to the website and click the link, it will download as a file on your computer. However, I want to automate this process. I have tried the following:
library(RCurl)
download.file("https://dshs.texas.gov/coronavirus/TexasCOVID19DailyCountyCaseCountData.xlsx", "temp.xlsx")
library(readxl)
tmp <- read_xlsx("temp.xlsx")
# Error: Evaluation error: error reading from the connection.
This method does download a temp.xlsx file to my drive. However, if you try and manually click on it to open, excel fails to open it. It knows it's size, but is unable to open.
.
readxl::read_xlsx("https://dshs.texas.gov/coronavirus/TexasCOVID19DailyCountyCaseCountData.xlsx")
# Error: `path` does not exist: ‘https://dshs.texas.gov/coronavirus/TexasCOVID19DailyCountyCaseCountData.xlsx’
Both of these methods are my go-to for downloading excel files from websites. Is there some specific reason why these methods don't work here?
When downloading certain file formats on Windows you need to specify that it should be a binary rather than the (usual) default of a text transfer - from the download.file() documentation:
The choice of binary transfer (mode = "wb" or "ab") is important on
Windows, since unlike Unix-alikes it does distinguish between text and
binary files and for text transfers changes \n line endings to \r\n
(aka ‘CRLF’).
On Windows, if mode is not supplied (missing()) and url ends in one of
.gz, .bz2, .xz, .tgz, .zip, .rda, .rds or .RData, mode = "wb" is set
such that a binary transfer is done to help unwary users.
Code written to download binary files must use mode = "wb" (or "ab"),
but the problems incurred by a text transfer will only be seen on
Windows.
In this case so that the file is written correctly use:
download.file("https://dshs.texas.gov/coronavirus/TexasCOVID19DailyCountyCaseCountData.xlsx",
"temp.xlsx", mode = "wb")
I am trying to download a ncdf file using rCurl. Can anyone provide any advice on why this is not working?
require(RCurl)
require(ncdf4)
url <- "https://oceandata.sci.gsfc.nasa.gov/MODIS-Aqua/Mapped/Seasonal_Climatology/4km/sst/"
filename <-"A20021722014263.L3m_SCSU_NSST_sst_4km.nc"
download.file(paste0(url, filename),destfile = paste0("~/Desktop/", filename), method="curl")
setwd("~/Desktop/")
files<-dir(pattern="*.nc")
f<-nc_open(files[1])
Error in R_nc4_open: NetCDF: Unknown file format
Error in nc_open(files[1]) :
Error in nc_open trying to open file A20021722014263.L3m_SCSU_NSST_sst_4km.nc
It appears that the file downloaded is an error file in XML format? If you open it in Notepad, you'll see it contains stuff like
Sorry, an error has occurred. Use the back button to return to the previous page or go to the Ocean Color Home Page
Are you sure that the filename you're wanting to download actually exists in that URL?
I try to download an excel file using download.file().
If I go directly to the link using the browser, I can download the file without problems.
However, using download.file does only download a broken file with Excel error: "The file you are trying to open is in a different format than specified by the file extension."
Here is my code:
url <- "http://obieebr.banrep.gov.co/analytics/saw.dll?Download&Format=excel2007&Extension=.xlsx&BypassCache=true&path=%2Fshared%2fSeries%20Estad%c3%adsticas%2F1.%20Tasa%20Interbancaria%20%28TIB%29%2F1.1.TIB_Serie%20hist%C3%B3rica%20IQY&lang=es&NQUser=publico&NQPassword=publico&SyncOperation=1"
download.file(url, destfile = paste0(base_dir, "test.xls"), mode = "wb", method="libcurl")
Any ideas how to download this file?
Many thanks for your help!
Try this, it works for me:
download.file(url,destfile = "./second.xlsx",mode = "wb")
The file you are trying to download is simply not an excel file. Actually what you obtain is an html file (try to change the file extension to '.html', then open in your browser). So your code is not the problem.
