Crash when calling 'run()'

[bkatgithub]

Hi,

I am doing a build based on the instructions in your blog. When I run it, it crashes when calling 'run(String[])'. I added some debug statements in the run function and it seems to be in the call to 'main(argc, argv)' in ffmpeg_controller.c. Logcat has the following messages. Am I missing something in my setup?

Can you share the command you are trying to execute?

Thanks.

I added sanityCheck function in ffmpeg_controller.c to return a string to make sure calls are getting to the jni function. And that call works - and I get the return value back in java. The call to run() causes the crash.

` String filesDir = "/storage/sdcard0/Download/"; Controller c = new Controller();

// sanity check to make sure calls are reaching jni funciton. // This works. String sanity = c.sanityCheck(); System.err.println("RESPONSE FROM SANITYCHECK: " + sanity);

// call to run() causes a crash c.run(new String[] { "-y",
"-i", filesDir + "in.mp4", "-vcodec", "copy", "-an",
filesDir + "out.mp4" });

`

Do you have write access on the directory? Do you have external write permissions?

Also please use "Controller.getInstance()" instead of "new Controller()". Controller is a singleton class. Using "new Controller" doesnot load the FFMPEG libs.

Thanks Madhavan! My external write permission was not enabled. Setting that and changing how Controller is instantiated has helped me get past that issue. I am able to work with ffmpeg now.
