Avisynth not refferecing subtitles

[azz]

Hi

the avisynth scripts are not passing through DVD subtitle stream info in the inbound mkv file.

FFMPEG works directly with the following filter.

-filter_complex "[0:v]scale=640:480[video];[1:s:0]scale=640:480[sub];[video][sub]overlay[out]" -map [out]

The ffmpeg action FFAStrans is failing with the following output error in the ffmpeg pipe:
Input #0, avisynth, from '\\VBOXSVR\SharedFolder\_Scratch\20160525110551\20160525-111139-778-6EFBEFD4458F\enc_av_customff_20160525-111151-429-2642A432E8E1.avs':

There is no subtitle track in AviSynth so you have to specify an external file to stream 1 and use that. You do this by adding "-i X:\MyCoolSub.srt " to your custom ffmpeg options.

I was getting an input error when i added the input mkv into my custom ffmpeg, as i gave this a go. I'll experiment some more.

thanks
