[Subtitle bug] I can't burn srt subtitles into the video

[bordon]

Summary of the bug:
When I transcode video (with a separate srt subtitle) on windows x64,it can't work correctly.

My environment is as follows:
ffmpeg version: the offical 64-bit static for windows
​https://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20160718-a49ed9e-win64-static.zip

OS: Win2008 x64
CPU: Intel i7 4770K with iGPU driver
GPU: Nvidia Geforce GTX 750 Ti with 368.81 driver

How to reproduce:
D:\ffmpeg\bin>ffmpeg.exe -i E:\movie\KB11-11-00.辛白林.Cymbeline.2014.1080p.BluRay.x264.DTS-WiKi\Cymbeline.2014.1080p.BluRay.x264.DTS-WiKi.mkv -vf "su
btitles=:filename=E:\movie\KB11-11-00.辛白林.Cymbeline.2014.1080p.BluRay.x264.DTS-WiKi\Cymbeline.2014.1080p.BluRay.x264.DTS-WiKi.srt" -c:v h264_nvenc

-s 1280X720 -gpu 0 -b:v 1400k -c:a aac -b:a 65k -f mp4 E:\output\Cymbeline.2014.1080p.BluRay.x264.DTS-WiKi.mp4

Return results：

[Parsed_subtitles_0 @ 0000000002c0f840] Shaper: FriBidi 0.19.6 (SIMPLE)

If transcode video only, it can work correctly.
After that, I consider perhaps i should use a slash in subtitle file path, so I try to use the following command:

D:\ffmpeg\bin>ffmpeg.exe -i E:\movie\KB11-11-00.辛白林.Cymbeline.2014.1080p.BluRay.x264.DTS-WiKi\Cymbeline.2014.1080p.BluRay.x264.DTS-WiKi.mkv -vf "su

But it return the following error:

Is the issue reproducible if you rename the subtitle file to sub.srt? Please attach the subtitle file here.

Please provide command line including complete, uncut console output to make this a valid ticket.

I have found the reason of the problem，It's the reason of libass library.
When I put the subtitle file in the same directory with the ffmpeg.exe program,it work correctly. But when I put the subtitle file in a different directory with the ffmpeg.exe program,it didn't work and return the following errors:

[Parsed_subtitles_0 @ 0000000002bef840] Unable to open /movie/KB11-11-00.杈涚櫧鏋?Cymbeline.2014.1080p.BluRay?.x264.DTS-WiKi/Cymbeline?.2014.1080p.BluRay?.x264.DTS-WiKi?.srt

I'm looking forward the offical can solve the problem as soon as possible.

Please reopen this ticket if you can provide the command line you tested together with the complete, uncut console output and the subtitle file as an attachment for this ticket.

Opening subtitles files in another directory works fine here with current FFmpeg and the subtitle filter.

My command line is as follows:

You need to fix the colons in your command line.

Replying to Cigaes:
Can you give me the correct command line?
Thanks.
