  • FFmpeg native AAC decoder

    30 juillet 2015, par Tran Toan

    I’m working on a commercial C\C++ app on Windows that need to decode AAC. I have looked at this question AAC Codec Library (libFAAC alternative)
    From the answer, it seems that FFmpeg has a native LGPL AAC decoder. However, when I looked at FFmpeg home page, I found no information about this decoder or what AAC object type it supports (only information about encoder). I have been searching for this for 2 days but I found almost nothing. So my questions are :

    1. What type of object type does native FFmpeg AAC decoder support or does it even exist ?
    2. If the above decoder does not exist then is there any alternative free library ? I have also looked at FDK AAC but I don’t understand its license, can I use it for commercial product ?

    Please help I’m new to audio codec.

  • Unwarping 180 VR Footage with FFmpeg v360 Filter

    5 avril 2021, par Ted Wilmont

    I am struggling at present. I have searched high and low for days and can't find a command that achieves what we want to do.

    


    We have stereoscopic 180 degrees VR footage in a side-by-side equirectangular format that we want to convert to flat so we can process using further AI software.

    


    We have already split the file in half across the width using FFmpeg so we have a "right" eye and a "left" eye video file.

    


    For each video file, we need to convert the 180-degree equirectangular footage to a flat, unwarped video file using FFmpeg (and the v360 filter).

    


    We've tried the following for example :

    


    ffmpeg -i 2LEFT.mp4 -vf "v360=input=equirect:ih_fov=180:iv_fov=180:output=flat" 2LEFTTEST.mp4


    


    However, this results in a very warped/misaligned video.

    


    Some command examples, tips, suggestions as to convert the now monoscopic 180-degree equirectangular footage to a flat video file will be greatly appreciated.

    


    Thank you for your help in advance.

    


  • Live website to video

    25 janvier 2016, par Asaf Nevo

    I have a website which shows a slideshow of pictures using JS.

    The pictures objects are coming from a web service and are being updated from time to time.

    In few days, I doing a test with a potential client to present the pictures slideshow on his big LED screen.

    He’s using BSPlayer for the content on screen, an able to present a website, but it will never be a clean full screen (the X button and such will always be presents).

    He’s the most comfort with presenting a video rather than a website.

    One of my ideas of solutions was to check if there is a way to stream a content of a website.

    Googling it got me to a solution combined ImageMagic and FFMPEG which you can read about here

    My problem is that this solution only creates a slide show out of static pictures - which I can do, but i’m losing the dynamic part of my live slideshow.

    Is there a tool for capturing websites and converting them into a stream of videos ?

    Or maybe a workaround to achieve the same functionality ?
