Hi

I have just finished compiling everything on Ubuntu 16.04. When I try to run ffmpeg I get:

error while loading shared libraries: libavdevice.so.57: cannot open shared object file: No such file or directory

On a new kubuntu 16.04 kvm gpu passthrough install, I ran into a couple problems. First, I had to install git to use the script. Please add that to the list of programs to install via apt. After everything compiled, I could not use nvenc as ffmpeg gave me the following error:
error while loading shared libraries: libavdevice.so.57: cannot open shared object file: No such file or directory
I had libavdevice-ffmpeg56 installed, but I suppose it wants libavdevice-ffmpeg57.

When I try to build it shows an error.

Found no assembler
Minimum version is nasm-2.13
If you really want to compile without asm, configure with --disable-asm.

Error.txt

I've received two reports that the script fails to build on some system with ffmpeg being unable to find libx264. Here is a detailed report of the errors below:

The error I get appears to be during the configure for ffmpeg:

2016-07-27 13:53:19 (1.72 MB/s) - ‘ffmpeg-3.1.tar.bz2’ saved [9329359/9329359]
ERROR: libx264 not found

I've looked at source/ffmpeg-3.1/config.log and determined that the x264 headers were not in place:

/tmp/ffconf.J7WYN2Vg.c:1:18: fatal error: x264.h: No such file or directory

compilation terminated.

I was able to correct this by adding "make install-lib-dev" to the x264 install after "make install" but I still have an issue finding libx264:

/usr/bin/ld: cannot find -lx264

The only file I could find that I think might match is libx264.a which does not get installed by x264's makefile. I think this might be a bug on x264's end. I added a simple cp after the "make install-lib-dev" added above and the build gets further:

cp libx264.a $build_dir/lib/

Now I get the following when building:

/usr/bin/ld: /home/redkrieg/nvenc/ffmpeg-nvenc/lib/libx264.a(common.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC

library.mak:99: recipe for target 'libavcodec/libavcodec.so.57' failed
make: *** [libavcodec/libavcodec.so.57] Error 1
make: *** Waiting for unfinished jobs....

OS: Ubuntu 16.04

Had to do "Installing the libx264-dev package is a workaround but it shouldn't be needed, we already provide it from our script"

But now when I launch OBS there is no option for window or desktop capture, unlike if I just installed ffmpeg & OBS through CLI

Tried installing OBS-Studio to enable nvenc on ubuntu 16.04 using build script provided here. After installation, obs-studio nvenc encoder lists in the drop-down, but fails when I start recording.

Now, I am unable to uninstall obs-studio. Tried below options.

1. Not able to see this in Ubuntu software list.
2. This does not get identified with "sudo apt-get remove --purge OBS*"
3. Tried sudo make uninstall - says uninstall script is not available.

However, when I search for OBS-Studio, it shows up and I am able to open the application as well.

Please help with the uninstallation steps.

I ran into an audio sync problem with staxrip that traced back to nvenc (3.23 (r667)).

Input file was originally bitstream-encoded to .iso using dvdfab 6, later converted .iso was to .mkv using MakeMKV and plays fine (good audio sync) in mpc-hc, etc:

Bug is the framerate detected by nvenc is 30p when mediainfo reports 24p. This issue reproduces in other (all) 24p files.

Adding --fps 23.976 to the command line changes input & output framerates to 24p and fixes the audio-sync problem.

Thanks for sharing nvenc, its a great tool.

i downloaded the scrip and even did the extra mile to get the newer codecs from nvidia but when the time comes to compile x264 it fails, attaching log file of the build, ignore the nvidia codec part, it's a dummy address.

Part of the terminal messages that are not in the log:

In line 225 of build.sh we execute "./configure" within the "build" subdirectory we just created within the clone from https://github.com/MaartenBaert/ssr.git. But shouldn't it be "../configure", as we are not in the main dir where the configure script resides, but rather in a subdir we just created?

I ran the script but when I run FFmpeg I get the error

Hi guys,

I'm trying to build ffmpeg version 3.4.4 in a docker container using node:6-slim image.

However, I'm hitting the following error.
I tried adding --extra-cflags="-I$BUILD_DIR/include -fPIC" without any success.

Any ideas?

why is this old version used?

I tried compiling on my Debian stretch and i got this error when executing the ffmpeg binary

./ffmpeg: error while loading shared libraries: libavdevice.so.58: cannot open shared object file: No such file or directory
the worst thing is that this dependency is only available on the testing and unstable debian repo :(

Here's the log.
config.log

./obs: error while loading shared libraries: libobs-frontend-api.so.0: cannot open shared object file: No such file or directory

I'm trying to install ffmpeg on a ubuntu 17.10
i follwed the the steps https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu given in the link

while running make

this error is shown.kindly share your views to solve the issue

It seems that ffmpeg removed the nvidia headers from their source so you'll have to do it yourself or add it to the make script

git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
make
sudo make install

as documented in this post
