Every then and now ffmpeg tells me

myfile.avi: Protocol not found
Did you mean file:myfile.avi

if executing ffmpeg -i myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4.

Using ffmpeg -i file:myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4 then fails:

file:myfile.avi: Protocol not found
Did you mean file:file:myfile.avi

Executing the same (out of bash history) after reboot (normally I just go into pm-suspend-hybrid) works, converting from .avi to .mp4 like expected.

Any ideas what might be the reason and how to fix this?

complete in-/output:

$ ffmpeg -i myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4

The comment of @andcoz lead me onto the right way: the problem exists as long as /usr/lib/chromium-browser/libffmpeg.so is loaded.

In my case this happens in some special use case:

The libffmpeg.so is used by the Vivaldi browser for showing proprietary video formats (H.264).

If I download a file via Vivaldi, and then go to its download panel, right click on the downloaded file and select 'Show in file manager', my file manager opens. It runs in the 'context' of the browser, so when I go a step further, and open a terminal out of that file manager session, this also runs in the context of Vivaldi.

For me this means, that there are a few environment variables set, which are not there, if I start a normal terminal session (not out of Vivaldi context).

These environment variables contain (among others) a LD_PRELOAD=/usr/lib/chromium-browser/libffmpeg.so. As that one causes libffmpeg.so to be loaded when running my conversion with ffmpeg, I tried an unset LD_PRELOAD in the terminal session and after that my conversion ran again fully normal.

So this is where the 'then and now' problem came from, I just was not aware of the case I am in a different environment variable context when starting my program chain out of Vivaldi.

Thx everyone for helping out.

Since you have this unpredictable behavior of ffmpeg (does not work first, but works after reboot), I would think that the program installation is somehow broken. The message

WARNING: library configuration mismatch

which you supply says that there is some problem in the installation. Googling this warning gives a feeling that the problem has existed for years, even with clean installations, but was never fully resolved. The most reasonable explanation, which I found, is following

Well, the warning is printed whenever you use a copy of the 'ffmpeg' binary with a copy of libavcodec (or any other library provided by the ffmpeg source package) that has been built with a different configuration. Which is the whole point of the 'libavcodec-extra*' packages: Enable additional functionality. (source)

If you follow this link you'll find some recipes how to resolve this issue. The most frequent one is (1), (2)

sudo apt remove libavcodec-ffmpeg-extra56

but it does not work for everybody. So may be the best solution would be to reinstall ffmpeg and/or the needed libraries.

p.s. Do not judge me too strict if I am wrong in my understanding of your situation and please let us know if any of this helps.

I came to this topic for the message, just to add one tip for users, I found out that if the filename itself has ':' in it would cause the problem, as some programs generate files with the time stamp like "audio 12:34:14.ogg"
