Lately I mado some chnages , and now geting an critical error : like : “no space left on device”
" [af#0:1 @ 0x600001ad9cb0] Error sending frames to consumers: No space left on device [af#0:1 @ 0x600001ad9cb0] Task finished with error code: -28 (No space left on device) [af#0:1 @ 0x600001ad9cb0] Terminating thread with return code -28 (No space left on device)"

ffmpeg -i movies/$1.* -i ~/Documents/indianul3.png -filter_complex “[1][0]scale2ref=w=ohmdar:h=ih0.1[logo];[logo]overlay=x=main_w-overlay_w-(main_w0.04):y=main_h0.14,subtitles=subs/$1.srt:force_style=’FontSize=22,WrapStyle=0,MarginV=35″ -preset fast -s 720×480 -vcodec libx264 -shortest output/$1-sub.mp4

I run the funtion indianull and expected it to convert a video , in my desired format + add logo + add subtitles ! Takes the original Video from on folder , Subtitles from another folder , and converts the video , and saves it in another folder ..

the issue i see only is :
"[af#0:1 @ 0x600001ad9cb0] Error sending frames to consumers: No space left on device [af#0:1 @ 0x600001ad9cb0] Task finished with error code: -28 (No space left on device) [af#0:1 @ 0x600001ad9cb0] Terminating thread with return code -28 (No space left on device) [out#0/mp4 @ 0x600001dd8540] video:0KiB audio:0KiB subtitle:0KiB other streams:0KiB global headers:0KiB muxing overhead: unknown"

I do defenitly have over 400GB free on My SSD !
Is an an speciffic folder that is full ? and can not hold any files ?

Any idea how to solve this ? or any suggestion how to try to solve ?
