In the console, it may be displayed:
SUB: Could not determine file format
Cannot load subtitles subtitle_file.srt.Causes and solutions
Wrong encoding
For example the .srt file is encoded in UTF-16 when the system expects UTF-8.
A simple way to test the validity of the file encoding, is to do:
$ cat -t subtitle_file.srtIf you get some garbage output like:
^@8^@9^@3^@
^@0^@2^@:^@2^@0^@:^@4^@3^@,^@9^@5^@0^@ ^@-^@-^@>^@ ^@0^@2^@:^@2^@0^@:^@4^@7^@,^@1^@5^@0^@
^@T^@h^@e^@r^@e^@ ^@w^@a^@s^@ ^@a^@ ^@b^@a^@r^@b^@e^@d^@ ^@w^@i^@r^@e^@
^@a^@n^@d^@ ^@t^@h^@i^@s^@ ^@G^@e^@r^@m^@a^@n^@ ^@c^@a^@m^@e^@ ^@u^@p^@ ^@t^@o^@ ^@m^@e^@.^@

The solution is to properly re-encode the file:
iconv -f UTF-16 -t UTF-8 subtitle_file.srt > subtitle_file_fixed.srtWrong format
