The problem is that your shift is effectively dividing by 16... so you end up losing information. You can't exactly represent any values which aren't exactly divisible by 16 (i.e. values which don't have the bottom four bits as 0000.) If... more 1/22/2014 6:20:49 PM

You haven't specified any parameters in your SQL, or a VALUES section - you're saying "I want to insert into these fields..." but not what you want to insert. It should be something like: string insCmd = "Insert into Accounts... more 1/22/2014 2:35:53 PM

It sounds like the problem is that ffmpeg is writing log information, and you're not reading it in the Java code. There will be a small buffer between the processes, and when that buffer fills up, ffmpeg will block when it tries to write... more 1/22/2014 1:20:49 PM
