[BUG] Pressing `s` gives `Error writing screenshot` if long filename.#146

Hi, Context: 1. `mpv` has been assigned as a backend to `pipe-viewer` in `~/.config/pipe-viewer/pipe-viewer.conf ``` video_player_selected => "mpv", video_players => { mpv => { arg => "--really-quiet --force-media-title=*TITLE* --no-ytdl --vo=gpu --hwdec=cuda", audio => "--audio-file=*AUDIO*", cmd => "/usr/bin/mpv", fs => "--fullscreen", novideo => "--no-video", srt => "--sub-file=*SUB*", }, ``` 2. When `mpv` is configured to grasp screenshot to the $PWD plays well with `pipe-viewer` 3. When `mpv` is asked to save the screenshot to a specific location in `~/.config/mpv/mpv.conf` ``` screenshot-template="~/Pictures/screenshots/mpv/%F/%p__%tm-%tY" local utils = require("mp.utils") local basedir = mp.get_property("options/screenshot-directory") mp.register_event("file-loaded", function() local filedir = mp.get_property("filename/no-ext") local dir = utils.join_path(basedir, filedir) mp.set_property("options/screenshot-directory", dir) end) ``` `mpv` standalone (outside `pipe-viewer) captures the screenshot as desired in the relevant folder specified above.** But `pipe-viewer` fails to screenshot with `Error writing screenshot!` when pressed `s`! Any idea? Thanks!
