(Linux) libavcodec.so.54: cannot open shared object file: No such file or directory [school project] #442

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
*What steps will reproduce the problem?*
1. Using IntelliJ
2. Add javacv libraries to project as well as having ffmpeg and opencv 
installed on the machine
3. Trying to initialize FFmpegFrameRecorder results in error

*What is the expected output? What do you see instead?*
I am attempting to use the RTMP protocol to stream video feed from my webcam
{{{
      recorder = new FFmpegFrameRecorder("rtmp://127.0.0.1:8107/live/test.flv", 640, 480, 1);
}}} 

The above statement results in
{{{

*What version of the product are you using? On what operating system?*
I am using Javacv0.7, FFmpeg 2.2.1, OpenCV
I am currently running Arch Linux 64 bit. I ran the command 'locate 
libavcodec.so', a few others are returned, but not #54.

Please provide any additional information below.
I directly downloaded the Jars from the downloads page

I just wanted to add that I tried the same thing on my Macbook Air and the same 
error occurs, however a different file is missing.

I am doing this project for an Undergraduate Research symposium presentation. 
So I appreciate any help.

I want to report this issue as solved! 
All I needed to do was install a package called 'ffmpeg-compat2' which provides 
version 54 of libavcodec. 

I still am not sure about what the solution for Mac is, but it is irrelevant 
for me at this moment, but I will come back to it.

Have you tried adding the JAR files from the "CPPJARs" archive to your 
CLASSPATH?

I have a similar problem on Windows 8.1 using the Maven module in IntelliJ 
13.0.2 via Gradle like this:

repositories {
    mavenCentral()
    maven {
        url "http://maven2.javacv.googlecode.com/git"
    }
}

dependencies {
    compile 'com.google.code.findbugs:jsr305:2.0.+'
    compile 'com.google.guava:guava:15.0'
    testCompile 'org.apache.commons:commons-lang3:3.1'
    testCompile 'junit:junit:4.+'
    testCompile 'org.assertj:assertj-core:1.5.0'
    testCompile 'com.googlecode.javacpp:javacpp:0.7'
    testCompile 'com.googlecode.javacv:javacv:0.7'
}

They appear on the CLASSPATH like this, which seems correct:

C:\Users\rphelps\.gradle\caches\modules-2\files-2.1\com.googlecode.javacpp\javac
pp\0.7\ff8f2a518e524ae8de093d6556fc21a6ab8f05b2\javacpp-0.7.jar;
C:\Users\rphelps\.gradle\caches\modules-2\files-2.1\com.googlecode.javacv\javacv
\0.7\310927e25b52136954b65608f341dfd5e5ad9d64\javacv-0.7.jar

I unzipped the FFmpeg and OpenCV libraries to:

C:\Users\rphelps\ffmpeg-2.1.1-win64-shared\
C:\Users\rphelps\opencv248\

I add those folders to my java.library.path like this:
-Djava.library.path=C:\Users\rphelps\opencv248\opencv\build\java\x64;C:\Users\rp
helps\ffmpeg-2.1.1-win64-shared\bin

Resulting in:

java.lang.UnsatisfiedLinkError: no jniavcodec in java.library.path

    at java.lang.Runtime.loadLibrary0(Runtime.java:849)

    at com.googlecode.javacv.cpp.avcodec.<clinit>(avcodec.java:39)
    at com.googlecode.javacv.FFmpegFrameGrabber.<clinit>(FFmpegFrameGrabber.java:103)

I can't find jniavcodec anywhere at all.

@ryancerium It's in javacv-windows-x86_64.jar, so try adding that to your 
CLASSPATH. And please ask your questions on the mailing list if possible, not 
here, thank you.

Please try again with JavaCV 0.9 and let me know if this problem still occurs, 
thanks!

Given the lack of feedback, I am guessing you figured out what was wrong, but 
please let me know if you still cannot get it running, thanks!
