If I want to convert a lot of eps files into pdf from a batch file (approx. 3200) then it happens again and again that some pdfs are invalid. If I convert them individually, a valid pdf will come out. What can this be?
epstopdf log entry for an invalid pdf (file paths shortened):
2021-01-14 15:48:29,303+0100 INFO epstopdf - this process (24156) started by 'cmd' with command line: C:\miktex-portable\texmfs\install\miktex\bin\x64\epstopdf.exe "auto61.eps" --pdf-version=1.5 --nocompress 2021-01-14 15:48:29,487+0100 INFO epstopdf.core - start process: mgs.exe -dUseFlateCompression=false -q -sDEVICE=pdfwrite -dSAFER -dAutoRotatePages=/None -dPDFSETTINGS=/prepress -dMaxSubsetPct=100 -dSubsetFonts=true -dEmbedAllFonts=true -dCompatibilityLevel=1.5 "-sOutputFile=auto61.pdf" - -c quit 2021-01-14 15:48:30,948+0100 INFO epstopdf - this process (24156) finishes with exit code 0
and the pdf looks like this (I have replaced the stream content with XXX)
%PDF-1.5 %Çì¢ 5 0 obj <</Length 6 0 R/Filter /FlateDecode>> stream XXX endstream endobj 6 0 obj 2039 endobj
EDIT:
Non "working" epstopdf version:
MiKTeX EPS-to-PDF Converter 4.0 (MiKTeX 20.12)
"Working" version:
