How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-bash
awk. The problem with pipingffmpeg -f metadatais that it doesn't output to the command line and asks for a filename to be stated, maybe people with moreffmpegknowledge knows a way to make it output to the command line. So I think I have to use a temporary file in this case, but only one rather than 3 thanks to you.-or/dev/stdoutas the file name.-should work for writing to standard output. I have updated the answer to use that.
