selenide-video-recorder 7.10.0 error when try to start ffmpeg software

[Vincent Daburon]

Hi,

I try the selenide-video-recorder v7.10.0 on my Windows 11 PC

But i have an exception because the binary ffmpeg is not find, see Exception Stack.

Did i need to install manually the ffmpeg software on my PC and change the PATH ?

Ok i read only 

https://github.com/selenide/selenide/releases/tag/v7.10.0

not
https://selenide.org/2025/08/20/selenide-7.10.0/

i don't see :

Important:

1. Now the video recorder requires ffmpeg to be installed on the computer.
2. The video file extension has changed from webm to mp4.

Hi,

To use ffmpeg without change the PATH.

In my maven project i add :

1) ffmpeg binary in my project in the src/test/resources : <PROJECT_HOME>/src/test/resource/ffmpeg-8.0-essentials-win-x64.exe

2) create profiles :

<profile>
<id>ffmpeg_windows</id>
<properties>
    <ffmpeg.binary.path>${project.build.directory}/test-classes/ffmpeg-8.0-essentials-win-x64.exe</ffmpeg.binary.path>
</properties>
</profile>
<profile>
<id>ffmpeg_linux</id>
<properties>
   <ffmpeg.binary.path>${project.build.directory}/test-classes/ffmpeg-8.0-essentials-linux</ffmpeg.binary.path>
</properties>
</profile>

3) And declare the environment variable  FFMPEG in my pom.xml

groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.5.3</version>
<configuration>
<systemPropertyVariables>
<org.slf4j.simpleLogger.showDateTime>true</org.slf4j.simpleLogger.showDateTime>
...
</systemPropertyVariables>
<environmentVariables>
<FFMPEG>${ffmpeg.binary.path}</FFMPEG>
</environmentVariables>
</configuration>
</plugin>

4) When i launch the test, i select a profil likes ffmpeg_windows

It's work on Windows but not yet test on Linux 

Regards.

Use ffmpeg without change the PATH and not pre-install ffmpeg tool.

For Linux (Almalinux 9.x)

I use the binary static compile from releases :  
https://github.com/btbn/ffmpeg-builds/releases

ffmpeg-master-latest-linux64-gpl.tar.xz  (only binary ffmpeg-n7.1-linux64-x64)

I add this binary in the src/test/resources/ffmpeg-n7.1-linux64-x64
but i need change the permission execute for this binary => use a ant task  chmod

The maven profile is :

<profile>
            <id>ffmpeg_linux</id>
            <properties>

                <ffmpeg.binary.path>${project.build.directory}/test-classes/ffmpeg-n7.1-linux64-x64
                </ffmpeg.binary.path>

Hi,

I see in the Java Classe : 
https://github.com/bramp/ffmpeg-cli-wrapper/blob/master/src/main/java/net/bramp/ffmpeg/FFmpeg.java
You could declare a system variable  FFMPEG to set the path to the ffmpeg binary.

public class FFmpeg extends FFcommon {

  public static final String FFMPEG = "ffmpeg";
  public static final String DEFAULT_PATH = firstNonNull(System.getenv("FFMPEG"), FFMPEG);

I put the ffmpeg.exe binary in the maven directory in src/test/resources => the binary will be copied in the target/test-classes directory

In my pom.xml i add this System variable with

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.5.3</version>
<configuration>
<systemPropertyVariables>
<org.slf4j.simpleLogger.showDateTime>true</org.slf4j.simpleLogger.showDateTime>

<org.slf4j.simpleLogger.dateTimeFormat>yyyy-MM-dd'T'HH:mm:ss:SSS</org.slf4j.simpleLogger.dateTimeFormat>
<org.slf4j.simpleLogger.showShortLogName>true</org.slf4j.simpleLogger.showShortLogName>
<selenide.headless>false</selenide.headless>
<selenide.downloadsFolder>target/downloads</selenide.downloadsFolder>
<selenide.timeout>20000</selenide.timeout>
<selenide.browser>${browser}</selenide.browser>
<selenide.video.enabled>${video.enabled}</selenide.video.enabled>
....
<FFMPEG>${project.build.directory}/test-classes/ffmpeg.exe</FFMPEG>

</systemPropertyVariables>

I see the the value in log
2025-08-27T10:22:11:477 [main] INFO PrTest - selenide.headless=false
2025-08-27T10:22:11:477 [main] INFO PrTest - selenide.browserBinary=C:\Program Files\Google\Chrome\Application\chrome.exe

2025-08-27T10:22:11:478 [main] INFO PrTest - FFMPEG=C:\dev\intellij_idea\tests_non_regression_auto\target/test-classes/ffmpeg.exe

But when i launch the test, i have an error :

Caused by: java.io.IOException: Cannot run program "ffmpeg": CreateProcess error=2, Le fichier spécifié est introuvable
        at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1143)

1) Why my System variable FFMPEG is not used ?

2) How set the PATH to ffmpeg binary without change the Windows PATH ?

3) How can i add the ffmpeg.exe directly in my maven project ?

The main problem will be how to launch ffmpeg in a GitLab Runner in docker with java maven and chrome without ffmpeg?

Regards.
