Hi all, I'm not sure if this has been discussed before, but I have the following problem. My Java app executes FFmpeg with linked librtmp (as an external command) like this: ffmpeg.exe -i "rtmp://xxxxxx" to retrieve information about a stream. While this works perfectly as a standalone command, it fails (FFmpeg crashes) if the Java app runs as a Windows service under Local System Account user. This is the Windows error log: Faulting application name: ffmpeg.exe, version: 0.0.0.0, time stamp: 0x4e1f6fc9 Faulting module name: msvcrt.dll, version: 7.0.7600.16385, time stamp: 0x4a5bda6f Exception code: 0xc0000005 Fault offset: 0x000143f9 Faulting process id: 0x1f28 Faulting application start time: 0x01cc5b3fc2d942c4 Faulting application path: d:\ffmpeg.exe Faulting module path: C:\Windows\system32\msvcrt.dll Report Id: 008b5ba2-c733-11e0-b15f-001d09292815 It works well again if the Service runs under an actual user. As this only happens when retrieving rtmp feed information I assume the same problem would appear with rtmpdump. Is this a bug or is this an expected behaviour? Thanks, Petr
