Comment (by Nick):
I asked on zeranoe.com to build a version of ffmpeg with '''--enable-
iconv''' to support option '''-sub_charenc'''
A new Windows build of ffmpeg built with --enable-iconv is now available:
[http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-20130406-git-7775992-win32-static.7z]
[http://ffmpeg.zeranoe.com/builds/readme/win32/static/ffmpeg-20130406-git-7775992-win32
-static-readme.txt]
Thanks to zeranoe.com!
I tested this version and now -sub_charenc is working ''(more or less)''!
The ''(first)'' characters are converted correctly from Windows ANSI to
UTF-8 but now I found another problem. If -sub_charenc option is used to
convert an srt file then the last character of every subtitle paragraph is
missing or not correct converted! (see screenshot)
It seems a problem of the "subtitles character encoding conversion"
function!
This problem seems independent whether the last character is an "ordinary"
character or a special character. Furthermore it is independent whether
the imported srt file is a Windows/DOS or Unix text file.
Could somebody please check this problem using option "-sub_charenc" with
an Linux build of ffmpeg and/or avcodec created with --enable-iconv?
Command line:
{{{
ffmpeg -i input.mp4 -sub_charenc CP1252 -i subtitle_test_2.srt -map 0:v
-map 0:a -c copy -map 1 -c:s:0 srt -metadata:s:s:0 language=ger
ffmpeg_srt-subtitle_2.mkv
}}}
