Ask VideoLAN President and Lead VLC Developer Jean-Baptiste Kempf Your Questions 204

VLC remains one of the most popular applications. First released over 15 years ago, VLC is open-source, and is available across multiple platforms including Windows, OS X, Linux, Android, ChromeOS, iOS, and it's coming to the Xbox One later this year. We thought it would be great to have Jean-Baptiste Kempf, President of VideoLAN non-profit organization (the maker of VLC media player). In addition, he is also a lead developer of VLC.

Leave your questions in the comments section below. Let's get this going.

    I recently installed the VLC app for FireTV stick and figured out how to stream from VLC on my PC. But I found that the VLC app couldn't work with a stream; it could only play files from network accessible storage like an SMB shared drive.

    I'm not necessarily asking the developers here - can anyone tell me how to stream to my three FireTV sticks across the house? Do I need to replace the FireTV sticks with some other more capable device? Will the FireTV VLC app ever support streaming?

      Apples and oranges. VLC is a client for playing video and audio files. What you want is a DLNA server and DLNA client software.
      Many "Smart Televisions" have DLNA clients built in to play streaming video but the DLNA standards are not implemented in a standard manner and it still takes experimentation to find compatible software with the hardware you have.
      Is FireTV set up to be a generic DLNA streaming client? I don't know. Probably not. Manufacturers want things proprietary so you have

        There's a VLC client app for FireTV. The description page says it plays network streams, but if that's true, there's no visible way to use this functionality in the app.

        Meanwhile, the VLC on my PCs can stream and be received by VLC on other PCs. I'd like to do similarly with the VLC app on the FireTV stick.

    Although VLC is excellent in many areas the subtitle system I believe needs a lot of improvement. Why does the end user have to select the decoding of a particular subtitle, can it not be autodeteted?

    Is it possible to make these requests to the VLC developer community and is it likely anyone would develop these specific feature enhancement?

    • There are other problems, For example that you can't have a black background bar around each line of the subtitles, just around the complete subtitle, which makes it way too large. My guess is that most developers don't care about subtitles much or come from countries where TV doesn't care about doing them right, either.

It would be great if there were some way to make VLC the player that worked with Power Point.

    Currently, we live in an era where media players have become quite a bit more sophisticated. For example, Windows Media Player or iTunes offer some pretty advanced features for managing large libraries, integrate heavily within their ecosystems, and some even come with complete stores, where you can buy songs with a single click. On the other end, there's players such as Audacious that focus on playing music, and only on that - and the result is that you get a very speedy and lightweight player, and the support of winamp skins makes it possible to heavily personalize. What role do you think VLC plays in the ecosystem, and more specifically, where do you think you want to take the project in the future?

    Would you consider implementing:
    1) Step back one frame (useful when paired with step forward one frame).
    2) Rewind (especially variable speed rewind, and with audio).
    3) Manually seek to location even if media doesn't support seeking (by simply playing the file up to that point).
    4) Finish at set time (automatically adjust play rate so that media will end at requested time) - I saw this on a DVD player once.

    #1 and #3 I find myself wanting on a fairly regular basis.
