  • Space Adventure CD-ROM

    1er octobre 2011, par Multimedia Mike — Game Hacking

    I acquired a CD-ROM entitled Space Adventure by Knowledge Adventure (I like these people ; they make decent, entertaining educational games). The physical media displays a copyright date of 1993, very early in the multimedia era.



    This 1993 CD-ROM makes proud use of multimedia files. What kind ? There’s a movies/ directory with 17 .mov files. It would be way too simple if these were QuickTime files, though. These represent a custom format, and video-only since a separate sounds/ directory contains .snd files with filenames corresponding to the .mov files. The .snd files are actually Creative Voice (a.k.a. VOC) files. As for this MOV format, wiki page and samples.



    I was also surprised to find the binary ultrasnd.exe file among the drivers on the disc. The Gravis UltraSound was released in 1992. The sound setup utility does not have an option for the GUS, however. No matter since DOSBox has great SB/Pro/16 emulation.

    I’m also a bit puzzled about why the DOSBox screenshots are 720 x 480 (posted here are various cropping and resizings).

  • FFmpeg stream dynamic png

    13 avril 2017, par Azarus

    I would like to know if its possible to stream a png or any kind of image using ffmpeg. I would like to generate the image contiously using nodejs that updates every 10 seconds. I would like to display game stats with this in a corner and mix it with some background music or pre recorded commentary on it. Additionaly i would like to mix a video and the image should act like an overlay.

    I am also not sure if using a transparent png image its possible to do

    I couldn’t get my head around doing the mixing with ffmpeg and its looks very complicated so i would like to get some help on it.

    I have video files stored in a folder that i would like to continously stream and mix different music and an image on it. I would like to have it all continously working without stopping the stream.

    Is it possible with ffmpeg cli on linux or i cant avoid using a desktop windows pc for such thing ?

  • FFmpeg - How to encode raw screen buffers (frame arrays) into a bitstream ?

    23 mars 2021, par bbasaran

    I have thousands of frame arrays (NumPy) with shape (3, 225, 400), which were obtained from game screens.

    


    Each one of those frame buffers has a label (screen class and timestamp). I'd like to create a bitstream from those arrays, to be used for analysis with an RNN or similar ML technique.

    


    Can I use FFmpeg to create a bitstream (e.g. bitrate on the y-axis, timestamp on the x-axis) ?

    


    I appreciate any help, thanks !
