Windows XP compatible non-SSE2 FFmpeg binaries

[FranceBB]

@Liisachan... After a few tests and wrapping my head around this, it looks like I got it wrong.
Basically you're absolutely right and it's effectively the other way round, namely that the ffms2 C plugin here only supports UTF-8 Script + UTF-8 Avisynth, but it doesn't support ANSI WinLatin.

As per the finding of the post in the AVSPmod mod topic, I updated the list with the new proper tests and it's actually more interesting than I initially thought:



Version: AvsPmod 2.7.6.0 x64
OS: Windows 10 Enterprise x64
Avisynth: 3.7.3 r4013 x64

Test file: àèéìòù.mkv

Script Encoding: ANSI
Script Avisynth encoding: System locale mbcs

FFVideoSource() r1387 ok
LWLibavVideoSource() v1156 ok
DirectShowSource() ok

Script Encoding: UTF-8
Script Avisynth encoding: System locale mbcs

FFVideoSource() r1387 ok
LWLibavVideoSource() v1156 ok
DirectShowSource() ok


Script Encoding: UTF-8
Script Avisynth encoding: UTF-8

FFVideoSource() r1387 ok
LWLibavVideoSource() v1156 ok
DirectShowSource() fail




Version: AvsPmod 2.7.6.0 x86
OS: Windows XP Professional x86
Avisynth: 3.7.3 r4013 x86

Test file: àèéìòù.mkv

Script Encoding: ANSI
Script Avisynth encoding: System locale mbcs

FFVideoSource() 2.40 (C Plugin) 2023-09-04 fail
LWLibavVideoSource() 2015-03-16 ok
DirectShowSource() ok


Script Encoding: UTF-8
Script Avisynth encoding: System locale mbcs

FFVideoSource() 2.40 (C Plugin) 2023-09-04 fail
LWLibavVideoSource() 2015-03-16 ok
DirectShowSource() ok


Script Encoding: UTF-8
Script Avisynth encoding: UTF-8


FFVideoSource() 2.40 (C Plugin) 2023-09-04 ok
LWLibavVideoSource() 2015-03-16 ok
DirectShowSource() fail



So, to recap:


ffms2 r1387
- Supports ANSI Script + mbcs Avisynth
- Supports UTF-8 Script + mbcs Avisynth
- Supports UTF-8 Script + UTF-8 Avisynth

ffms2 c plugin 2023-09-04 (the one from this topic)
- Supports UTF-8 Script + UTF-8 Avisynth
(anything else will only work if the file doesn't have accents)

libav v1156
- Supports ANSI Script + mbcs Avisynth
- Supports UTF-8 Script + mbcs Avisynth
- Supports UTF-8 Script + UTF-8 Avisynth

libav 2015-03-16
- Supports ANSI Script + mbcs Avisynth
- Supports UTF-8 Script + mbcs Avisynth
- Supports UTF-8 Script + UTF-8 Avisynth


DirectShowSource
- Supports ANSI Script + mbcs Avisynth
- Supports UTF-8 Script + mbcs Avisynth



So the question for Reino now actually shifted to whether he's willing to support Enhanced ANSI like WinLatin ANSI via system locale (mbcs) for the ffms2 C plugin by doing what StvG is doing in the normal ffms2 r1387 plugin or not.


Apologies for the whole mess, but it was actually far more complicated than I originally anticipated.
