Package not found - add libav to PKG_CONFIG_PATH environment variable

19 mars 2019, par Brayton Larson

I am attempting to build the Parrot SDK and when running the command it continuously fails due to multiple libav package variants not being found. Below is the error message.

As I understand it libav has been replaced by ffmpeg but the build should still be able to reference the packages as libav. I’ve tried adding different paths to PKG_CONFIG_PATH using `export PKG_CONFIG_PATH=...’ but with no success. It is possible I’m not adding the correct path, I used ’dpkg -L ffmpeg’ to locate the package. The output of that is :

...of which I can assume the useful part is ’/usr/bin’ which i added to my PKG_CONFIG_PATH and still the same error when building. I am running Ubuntu 18.04 LTS. I’m at a loss and have been grinding at this for the past 2 days, any help would be GREATLY appreciated. Thank you and I’m happy to provide more needed information. As a small request, I am pretty new to Linux so if you could include as many details in command line operations as possible it would help alot.

Cutting whatsapp shared videos using FFMPEG

2 août 2015, par Bhuvnesh Varma

I am using hiteshsondhi88/ffmpeg-android library to time or cut videos.I have added below dependency.

compile 'com.github.hiteshsondhi88.libffmpeg:FFmpegAndroid:0.2.5'

I am using below command

execFFmpegCommand("-i " + path + " -ss " + startMs / 1000 + " -to " + endMs / 1000 + " -strict -2 -async 1 " + dest.getAbsolutePath());

to cut or trim videos.

private void execFFmpegCommand(final String command) {

        try {

            ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {

                @Override

                public void onFailure(String s) {

                    Log.e("Preview", "FAILED with output : " + s);

                }



                @Override

                public void onSuccess(String s) {

                    Log.e("Preview", "SUCCESS with output : " + s);

                }



                @Override

                public void onProgress(String s) {

                    Log.e("Preview", "Started command : ffmpeg " + command);

                    Log.e("Preview", "progress : " + s);

                }



                @Override

                public void onStart() {

                    Log.e("Preview", "Started command : ffmpeg " + command);



                }



                @Override

                public void onFinish() {

                    Log.e("Preview", "Finished command : ffmpeg " + command);







                }

            });

        } catch (FFmpegCommandAlreadyRunningException e) {

            // do nothing for now

        }

    }

Its working for most videos but for some videos its NOT working especially for videos that are shared from whatssapp.It gives below error..I am using Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_MOVIES ) for storage of videos.

Linking against ffmpeg libs on Rust gives `vdp_device_create_x11` (libvdpau-dev missing ?)

7 octobre 2020, par Guerlando OCs

I'm trying to link against ffmpeg libraries, in rust, and getting as the only error :

undefined reference to `vdp_device_create_x11&#x27;&#xA;

Here's the libs linked :

fn main() {&#xA;    println!("cargo:rerun-if-changed=build.rs");&#xA;    println!("cargo:rustc-link-lib=static=z");&#xA;    println!("cargo:rustc-link-lib=dylib=dl");&#xA;    println!("cargo:rustc-link-lib=static=X11");&#xA;    println!("cargo:rustc-link-lib=dylib=vdpau");&#xA;    println!("cargo:rustc-link-lib=dylib=va");&#xA;    println!("cargo:rustc-link-lib=dylib=va-drm");&#xA;    println!("cargo:rustc-link-lib=dylib=va-x11");&#xA;    println!("cargo:rustc-link-lib=dylib=xcb");&#xA;}&#xA;

On C++ I used to link with all these libs above + some for GTK and it worked. Don't know why it wont work now.

On errors when compiling c code with ffmpeg library it says that I should link against -lvdpau - libvdpau-dev

I tried adding

    println!("cargo:rustc-link-lib=dylib=vdpau-dev");&#xA;

but I get

  = note: /usr/bin/ld: cannot find -lvdpau-dev&#xA;

Even though I installed libvdpau-dev. Indeed,

ldconfig -p | grep vdpau&#xA;        libvdpau.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libvdpau.so.1&#xA;        libvdpau.so (libc6,x86-64) => /lib/x86_64-linux-gnu/libvdpau.so&#xA;

Why libdpau-dev is missing ? I'm on ubuntu 20, apt-get install -y libdpau-dev. Finny thing is that C++ compiles perfectly in this same docker container without any modifications and without libdpau-dev

UPDATE :

nm -D /lib/x86_64-linux-gnu/libvdpau.so | grep x11&#xA;0000000000001d50 T vdp_device_create_x11&#xA;

UPDATE :

note: /usr/bin/ld: /home/dev/orwell/liborwell_rust/target/debug/deps/libffmpeg_sys_next-109176c9182219d2.rlib(hwcontext_vdpau.o): in function `vdpau_device_create&#x27;:&#xA;          hwcontext_vdpau.c:(.text&#x2B;0x686): undefined reference to `vdp_device_create_x11&#x27;&#xA;

The file hwcontext_vdpau.o is from ffmpeg : https://ffmpeg.org/doxygen/trunk/hwcontext__vdpau_8c_source.html

My theory of why it worked for your case but not mine is that in your case you link these libraries after the code that uses vdp_device_create_x11. In my case, I think it links my code against the libs I provided + ffmpeg libs. So maybe ffmpeg libs come after or before the libs I provided.

Well, since I'm linking against the project that links with ffmpeg, I think this is what's happening :

my_code is being linked against ffmpeg-sys-next crate + libs I provided. Where ffmpeg-sys-next crate contains the ffmpeg libs. I just don't know if the order is

ffmpeg-sys-next crate + libs I provided

libs I provided + ffmpeg-sys-next crate.

If ffmpeg needs vdp_device_create_x11, then vdp_device_create_x11 should come before ffmpeg or after ?

Is it possible to control if the crate dependencies are linked after or before the libs I provided ?

UPDATE :

Running `rustc --crate-name liborwell_rust --edition=2018 src/main.rs --error-format=json --json=diagnostic-rendered-ansi --crate-type bin --emit=dep-info,link -Cembed-bitcode=no -C debuginfo=2 -C metadata=a40686dab33e6453 -C extra-filename=-a40686dab33e6453 --out-dir /home/dev/orwell/liborwell_rust/target/debug/deps -C incremental=/home/dev/orwell/liborwell_rust/target/debug/incremental -L dependency=/home/dev/orwell/liborwell_rust/target/debug/deps --extern ffmpeg_next=/home/dev/orwell/liborwell_rust/target/debug/deps/libffmpeg_next-c150275f8ec2ece5.rlib --extern liborwellprofile_protobuf_rust=/home/dev/orwell/liborwell_rust/target/debug/deps/libliborwellprofile_protobuf_rust-85a803bf8441d976.rlib --extern phf=/home/dev/orwell/liborwell_rust/target/debug/deps/libphf-0282e4d662343769.rlib --extern protobuf=/home/dev/orwell/liborwell_rust/target/debug/deps/libprotobuf-525fd12c456cb486.rlib -l static=z -l dylib=dl -l dylib=vdpau -l static=X11 -l dylib=va -l dylib=va-drm -l dylib=va-x11 -l dylib=xcb -L native=/home/dev/orwell/deps/ffmpeg/build/linux/x86_64/lib`&#xA;

Looks like the ffmpeg libraries are the last thing passed to the compiler/linker : -L native=/home/dev/orwell/deps/ffmpeg/build/linux/x86_64/lib
