I am trying to pipe an output from avconv to grep but somehow the pipe is not working correctly. The following ways are not working:
avconv -i MOVIE.mkv | grep SOMETHING
- Which should show only the lines from the avconv that have SOMETHING in them.
avconv -i MOVIE.mkv pipe: | grep SOMETHING
- Which should show only the lines from the avconv that have SOMETHING in them.
avconv -i MOVIE.mkv pipe:1 | grep SOMETHING
- Which should show only the lines from the avconv that have SOMETHING in them.
How can I output the information from avconv to pipe?
Why is it not working?
Piping something like this works, but not the -i
information parameter: avconv -codecs | grep "264"
Tested on 12.04 and 12.10
SOMETHING
