The file header reads:


This installation of bash has been set up to use an init system similar
to the tcsh installed by OS X.

In order to use this configuration:

 echo "source ~/.bashrc"  > ~/.bash_profile
 echo "source /sw/share/init/bash/rc" > ~/.bashrc
 echo "source /sw/bin/init.sh">> ~/.bashrc


here I am not sure whether one has to copy the exact line into the command 
line, i.e. actually pipe the echo commands into ~/.bash_profile (does not 
exist yet), and ~/.bashrc, or to input the echo commands into those files 
(i.e. without overwriting the rest)?

Actually, .bashrc is already being sourced on my system, which begins with 
a line

test -r /sw/bin/init.sh && . /sw/bin/init.sh

but not the actual source command. After manually sourcing these in a 
shell the "bash-3.2" has been replaced by something like [xdsl-somenumber] 
(and probably to something else when I'm offline), but the behaviour 
doesn't change.

I can also manually type "bash" (which refers to /sw/bin/bash), giving me 
a "bash.4.0". However, the missing command(s) are not yet available.

What else is necessary to get the missing commands like seq? Or are there, 
besides the naked version numbers, also different "flavours" of bash, some 
providing other sets of commands (of commands with different options) than 
others?

Sorry that I am not born with expert knowledge and thus bothering the 
list with such questions, but I am honestly confused now...

Best wishes,

Ingo

Just installing bash via Fink (Commander) doesn't set Fink's bash as
your default shell.  I last tried to set a Fink shell as default around
OS 10.3, and that required changing an entry in NetInfo (now Directory
Services) and rebooting.

- From "fink info bash":

...
Usage Notes:
 See /sw/share/doc/bash/README.Fink for configuration advice.
...

Check that out and see if it has information on how to make it your
default.

Thanks. According to this, ffmpeg 0.6 is running on my office computer
while 0.4.2 from Fink.

In particular, I am missing for example the seq command for easy renaming
of a bunch of files. I got the tip that an update to bash 4.0 might help.
However, even after this update the bash doesn't seem to be active now
(the prompt is still labelled "bash 3.2" and seq is still missing.
Probably I have to update some initialization, either /sw/bin/init.sh
(which is still of an older age, thus unchanged despite installation of
bash 4.0) or .profile or .bashrc. Or did I miss some important component
here (i.e. just installing bash via Fink Commander isn't enough)?

You're not comparing identical versions, however, so this isn't just a

Ah, strange. On Linux you also have to exactly specify the number format,
but if something's wrong, ffmpeg just complains about files that cannot be
found. So I did expect a similar error message here and concluded that
some component of ffmpeg is missing.

BTW I cannot really specify the version of the Linux version too.

ffmgep -version returns:

FFmpeg version SVN-r23334, Copyright (c) 2000-2010 the FFmpeg developers
  built on May 26 2010 13:01:16 with gcc 4.4.4

and many config details. I do not know how version "SVN-r23334" is related
to version "0.6...". I can only guess that it is a rather new version.
Therefore, it is very likely that there is currently no ffmpeg that can
deal with unformatted integer numberings. However, this is not an
uncircumventable obstacle.

Many thanks so far for the suggestions!

BTW I also have seen that Fink's bash is newer (4.0) than Apple's (3.2).
Does an update make sense or are the differences too marginal to bother
with?

Fink _deliberately_ does _not_ use its compiler packages to build
packages unless a package explicitly asks for that.  Otherwise packages
will build differently (or fail) depending on whether a Fink gcc package
is installed or not.

Hanspeter's installation uses Fink.  It will install within the Fink
tree, overwriting the ffmpeg version that you installed from the
official distribution.  No additional entropy.

I just tried this with Fink's current ffmpeg-0.4 and got the same 
result.  However, there is a solution.

This is perfectly normal and expected.  Most Fink packages use XCode's 
gcc unless they absolutely need to use one of Fink's newer GCCs.

> Does anyone have any hints what's going on here?

Actually, I do now :)

- For pic.png.1 --> pic.png.%d: could not find codec parameters

- For pic.png.001 --> pic.png.%d: I/O error occured. Usually that means 
that input file is truncated and/or corrupted.

You need to pad %d as %03d for 001, 002, etc. thought that will still 
fail here at the end.

- For pic001.png --> Success!

So at least at Fink's current version, the file format extension 
apparently needs to be the last entry in a filename and %d must be 
padded appropriately.

Unfortunately not, and I am getting more and more the suspicion that the
installation is somewhat corrupted:

Actually, I tried the command

ffmpeg -f image2 -i sph.gif.%d sph.mp4

(the input files, from an exploded animated GIF with gifsicle, are
sph.gif.000, sph.gif.001 ...), and

ffmpeg -f image2 -i sph.gif.%d.jpg sph.mp4

after converting the sph.gif.*** into jpegs via convert (imagemagick). In

Usually that means that input file is truncated and/or corrupted.

The input file and its temporary .gifs and .jpgs can be easily processed
this way on a Debian Linux machine, so there is nothing corrupted about
these files.

What concerns me first is that Fink obviously tried to compile the stuff
via Apples overaged GCC 4.0.1 instead of Fink's GCC 4.4. After all, ffmpeg
obviously does not know its own version.

Does anyone have any hints what's going on here? Before I try an
independent installation (like the one mentioned by Hans Peter) without
knowing where it will spread its components over the system (I am usually
trying to minimize this to keep the system's entropy as low as possible
;-)).

Me too.  The instructions from here

The example command I gave above works with the ffmpeg-0.5.1 in my 
experimental tree, you shouldn't need to wait for the 0.6 version for that.

Ah, I'm a bit surprised about this. I'd have thought that combining images 
into a movie would be among the very first features of ffmpeg since 
creating movies seems to be more basical than converting existing ones.

Maybe, when I find time.

Unfortunately, I currently don't have too much time to make some big 
experiments on my system (does this version spread its components over the 
whole standard system paths as most installations do?) unless I am forced 
to.

Ah, thanks, if this is really no big deal, this would be fine!

Fink's ffmpeg is currently 2 years old, so it is possible that joining 
pictures into a movie doesn't work in that version.  The maintainer has 
been busy and unable to update to the newer version.

I have a test version of ffmpeg-0.5.1 available here 
 
that you can try (and it does join PNGs to a movie with this command: 
ffmpeg -f image2 -i pic%d.png foo.mp4).

FFmpeg 0.6 just came out and I'll try to make a version of it available 
for testing (maybe this weekend).
