I'd say so. While at Nokia I had to attend few legal training and if you plan to circumvent author's desire you're mostly in trouble. If VLC had that to avoid people to use it in proprietary software they can bug you and court may agree. This is the case with any IPC, often considered "safe", is not 100%. moreover... is your VIDEO PLAYER app that complex that can't get code released? I recall your boss (or it was you?) talking to me at ELC-E last year and you have a very, VERY, specific domain thing, likely releasing the code would not harm your business as it depend on a series of things (hw) to be valuable. At least release the video player if you want to use VLC and be safe. If you make your video player app GPL and do the communication with that using IPC, then you're safe as you're complying with VLC and you have the option to sue yourself on the other side, of course you won't ;-) BR, -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -------------------------------------- MSN: barbi...@gmail.com Skype: gsbarbieri Mobile: +55 (19) 9225-2202 ------------------------------------------------------------------------------ Download new Adobe(R) Flash(R) Builder(TM) 4 The new Adobe(R) Flex(R) 4 and Flash(R) Builder(TM) 4 (formerly Flex(R) Builder(TM)) enable the development of rich applications that run across multiple browsers and platforms.
