-pattern_type glob -i '*' fails with " *: No such file or directory"

[dE_logics]

I'm trying to get input of all files (mix of jpg and png images) with
the following --

-pattern_type glob -i '*'

However I get --

*: No such file or directory

[Carl Eugen Hoyos]

To make this a valid ticket, please provide your failing command line together with the complete, uncut console output.

I have never used glob, is "*" a valid pattern with the usual meaning?

'*' is a valid ​glob.

This looks quite outdated, is the problem also reproducible with current FFmpeg git head?

This cannot (currently) work:
Changing codecs in a stream is not supported.

Generally, in your command line * does not indicate a demuxer (but glob only works for the image2 demuxer), so you have to specify it with -f image2. If you don't provide a suffix on the command line, the image2 demuxer doesn't know which codec to use (there is no image codec autodetection), so for * you have to specify the codec with something like -vcodec targa.

Thanks for clarifying.

Autodetection of image file codecs was implemented, it unfortunately does not work for jpeg.

Changing codecs in a stream is still not supported, see ticket #3661.
