Problem getting ffmpeg

I was trying to install ffmpeg on a human server and I am having trouble compiling it. I used both the .5 version on the site’s download page and the latest copy of svn, but it still won’t compile.

It should be noted that I was logged in as root when compiling. First of all,

The problem is that if I run the ./configure script, this
may spit out:

Unable to create and run archives in / tmp. Set the TMPDIR
environment variable to a different directory and make sure this type of noexec is not mounted.
Reasonable play with him failed. You

If you think configure has made a mistake, be sure to use the latest SVN version. If the latest version doesn’t work, please report the problem to
ffmpeg on the mplayerhq.hu mailing list or IRC #ffmpeg about irc.freenode.net.
Add the “config.err” log file generated with skew as it helps
solve the problem.

Now, mainly because I am logged in as root, I should really be having trouble accessing / tmp, so I suspect this is just oshibca in the canceled vbulletin. Not seriously. So, I defined most of the
TMPDIR variables in another directory and checked the configuration. Now it seems to be ok to generate config.h and not generate any errors.

However, when I run make, it starts compiling normally, and then suddenly
stops with the following error:

File included in libavdevice / v4l.c: 33:
/usr/include/linux/videodev.h:56: Error: Syntax error before “ulong”
/ usr / include / linux / videodev. h: 72: Error: Syntax error before token
libavdevice / v4l ‘}’. c: In function ‘grab_read_header’:
libavdevice / v4l.c: 75: Error: known memory size for ‘tuner’
libavdevice / v4l is’t.c: 133: Error: Invalid use of `sizeof ‘on incomplete

libavdevice / v4l.c: 140: Error: invalid financial application` sizeof’ too incomplete
enter `video_tuner ‘
libavdevice / v4l Warning: c: 75: tuner variable not used ‘
make: *** [libavdevice / v4l.o] error 1

This happens regardless of whether I am using svn version 0.5 or the latest.
The main reason I am trying to install the latest version is because one of our users Your
should be able to convert QuickTime movies. There is a way to use the specific version that we have now installed (SVN-r12192), which would be great.
Or if someone can tell me what is wrong with the installer. I’ll be here, glad to the latest version.

PS I have posted this on ffmpeg.issues, but not sure if it will show up there
so I am posting here as a bon.

Add a line at the beginning under “v41.c”
#define ulong unsigned long

Hello
I was trying to install ffmpeg on our server and I am having problems compiling

. I used both version 2 of the.5 on the download page – online copy and the latest copy of svn and it still doesn’t compile an event when trying to compile.
The first problem was when I ran the ./configure script, the program gives a message: Unable to create and run while / tmp files. Set the TMPDIR
environment variable to a different directory and make sure anything not mounted is set to noexec.
The sanity test did not pass.
If you think you have made a wrong configuration, you mustPlease use the latest version of
provided by SVN. If the latest version doesn’t work, report the problem to
ffmpeg mplayerhq.hu by pointing it or IRC to
irc # ffmpeg.freenode.net.
Frequently add the “config.err” log file generated by configure as it helps to solve the problem.
Now I’m thinking about getting rooted in the script. Not seriously. So I set the
TMPDIR variable in a different directory and ran the installer. It seems to be working fine now as it generates config.h and has no flaws.
However, when I run make, compilation starts fine and then suddenly
/ usr / include / linux / videodev .h: 56: Error: Syntax error before “ulong”
/ usr / include / linux / videodev.h: 72: Error: Formatting error before token
libavdevice / v4l ‘}’ .c: 75: Error: Known memory size of “Tuner”
libavdevice / v4l unknown. c: 133: Error: Applying `sizeof ‘to incomplete
type` video_tuner’
libavdevice /v4l.c:140: Error: Application terminated by `sizeof ‘to incomplete
type` video_tuner’
libavdevice / v4l.Warning: c: 75: Variable `tuner ‘thrown
make: *** [libavdevice / v4l.Error o] 1
This means I am using version 0.5 or later The latest version of svn.
The main reason I try to install most versions is because one of our
users should be able to convert QuickTime images. The version we installed right away (SVN-r12192) has a way, which would be great.
Or if a friend or relative could tell me what was wrong, including the installer, I would be here dear
to see the latest version.
Thank you.
PS I posted this on ffmpeg.issues, but I’m not sure if it should be visible there, so I post there too.

Hello,

Enter these? sh libs? (they have the option to install the complete required packages
required by ffmpeg) for.

Run this process command? sh configure? Will be (this allows each option to convert
to ffmpeg).

Then try converting all world class video formats and see if most
work, should it work.

Hello,
I was trying to install ffmpeg on our internet and I am having trouble collecting
. I have used both 0 the.5 options on the website download page, the specific and most recent copy of svn, and it doesn’t compile when I want to compile.
First problem when I do this ./ run configure script it spits out
Unable to build and run in / tmp folders. Set the time of the TMPDIR
environment variable to a different directory and make sure it is not connected to the SVN version. If the latest version does not work, please report the problem to the ffmpeg-user mplayerhq.hu mailing list or IRC On
irc # ffmpeg.freenode.net.
Add the entry file “config. get it wrong.” one “produced by configure as a special help – the solution will fix the problem.
Now that I am logged in as root, I should not have access to / tmp, so I guess that this is definitely a bug in the script. It doesn’t really matter. So I set the TMPDIR variable
when you need to change directory and run configure, now it looks like it works
fine as this tool generates config.h and does not give out no errors.
But while you run make, compilation starts normally and then suddenly
/usr/include/linux/videodev.h:56: Error: Syntax error before “ulong”
/ usr / include / linux / videodev.h: 72: Error: Formatting error before token
libavdevice / v4l ‘}’. c: 75: Error: known memory size with “Tuner”
libavdevice / v4l is’t.c: 133: Error: Invalid application, mostly related to “sizeof” too incomplete
type` video_tuner ‘< br> libavdevice / v4l.c: 140: Error: invalid after applying `sizeof ‘to incomplete
type` video_tuner’
libavdevice / v4l Warning: c: 75: new variable `tuner ‘
make: ** * [libavdevice / v4l.Error o] 1
This happens regardless of whether I am currently using version 0.5 or the latest svn.
The main reason I’m trying to install the latest version is because one of our
needs help converting QuickTime movies. There is a way to do this with the version we have installed (SVN-r12192), that would be great.
Or, if in many cases someone can tell me what is wrong with someone’s installer, I would like to have the latest version here.
Thank you.
PS I posted this to ffmpeg.issues, on the other hand, I don’t know if there will be a little more there, so I am posting here compared to a good one.
