I'm trying to write bash script, which I can use to start encode of my video for web player, and also log to file when it started / finished.
It looks like this:
#!/bin/bash
>/var/www/stat/encode.txt
echo "on $(date +%s)" > /var/www/stat/encode.txt
ffmpeg -i 'suzumiya.mkv' -preset slow -crf 18 -c:v libx264 -c:a aac -strict -2 -movflags faststart -tune animation -profile:v baseline -vf "ass=suzumiya.ass" 'suzu.mp4'
echo "off $(date +%s)" > /var/www/stat/encode.txt
When I run it, it tells me:
'NULL @ 0x20ad4c0] Unable to find a suitable output format for 'suzu.mp4
: Invalid argument
When I just copypaste the ffmpeg code to console, it works well, no error. Where can be problem?
Full output:

You shouldn't need to, but try adding
-f mp4
before the output filename. – stib – 2014-06-23T08:32:20.053Please note that you have to indent code by 4 spaces (use the code button in our editor and check the preview). For your issue: Are you absolutely sure the script is exactly as you posted here? Nothing else apart from the quotes? Try replacing single with double quotes. It shouldn't really matter but you might have some special character there. – slhck – 2014-06-14T18:48:22.300
