RasPi V4L4J driver does not start for the second time
See original GitHub issueThis is in regards to V4L4J driver used on Raspberry Pi with CSI camera module.
At the first time driver works well, but every next run fails with the following stack trace and camera module power turned on.

Hi @haoyun1129,
Here is the fork I used to build v4l4j JAR used by webcam capture driver:
https://github.com/sarxos/v4l4j
After you clone it into your local git repo, please replace these files with the ones you compiled on your RasPi:
https://github.com/sarxos/v4l4j/tree/master/src/main/resources/META-INF/native/linux-armhf
After this is done go to the repository root directory and run
mvn clean install. This will create JAR intargetdirectory. Just put this JAR in your application’s classpath and remove the old one beforehand.That is all.
@sarxos I have download and built the v4l4j on my Pi but how to replace it in webcam-capture?
