"Print a text file to STDOUT using ffmpeg" ffmpeg -v quiet -f data -i input.txt -map 0:0 -c text -f data - I tried this in a directory with input.txt with some random text Nothing.
So changed the verbosity to trace ffmpeg -v trace -f data -i input.txt -map 0:0 -c text -f data -
---snip-- [dost#0:0 @ 0x625775f0ba80] Encoder 'text' specified, but only '-codec copy' supported for data streams [dost#0:0 @ 0x625775f0ba80] Error selecting an encoder Error opening output file -. Error opening output files: Function not implemented [AVIOContext @ 0x625775f09cc0] Statistics: 10 bytes read, 0 seeks
I was expecting text to be written to stdout? What did I miss?
It's not working for me either, on FFmpeg 7.0.2. I suspect something has changed in FFmpeg since that command was shared on the Reddit post mentioned on the website. That was a few years ago.
However, from the same Reddit thread, this works:
ffmpeg -v quiet -f data -i input.txt -map 0 -f data pipe:1
EDIT: just verified the `-c text` approach works on FFmpeg major versions 4 and 5. From FFmpeg 6 onwards, it's broken. The `pipe:1` method works from FFmpeg 5 onwards, so the site should probably be updated to use that instead (also, FFmpeg 5.1 is an LTS release).
