    include video files in OpenGL...

    As promised, video.cpp here attached plays a mp4 video whose codecs appear below. Based on http://dranger.com/ffmpeg/, running Windows x64, Visual Studio 2015, SDL2, ffmpeg 4.0 and C++. Hope it helps! Input #0, mov,mp4,m4a,3gp,3g2,mj2, from ‘crawl.mp4’: Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 creation_time : 1970-01-01T00:00:00.000000Z Duration: 00:00:29.00, start: 0.000000, bitrate: 689 kb/s Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 1344x680, 612 kb/s, 10 fps, 10 tbr, 10 tbn, 20 tbc (default) Metadata: creation_time : 1970-01-01T00:00:00.000000Z handler_name : VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, mono, fltp, 75 kb/s (default) Metadata: creation_time : 1970-01-01T00:00:00.000000Z handler_name : SoundHandler screen final size: 1344x680 video.cpp

    include video files in OpenGL...

    Thank you for your quick reply, Finalspace! Will look into it and keep you updated. ;-))) In fact, was trying to avoid extra dependencies but FFmpeg may be the way to go for my software to remain cross-platform, per a similar post on stackoverflow. Also posted in NeHe Productions forum concerning the null pointer in their tutorial. Copy both links here below for reference. https://stackoverflow.com/questions/39059959/vfw-avistreamgetframeopen-returns-null https://www.gamedev.net/forums/topic/697579-avistreamgetframeopen-returns-nullptr/
  3. Hey, hey, hey! Would like to include in my game 2 short avi videos I made in Blender. Went over NeHe lesson 35, it reads the supplied avi file but when I try to read my avi files, they both give nullptr for lpbi because of pgf being nullptr on line 106, see below. There is a similar post on stackoverflow, link here below as well. Would you, please, update the tutorial, please? Thank you so very much! ;-))) PS. Here attached one of the avi files I am trying to read. pgf=AVIStreamGetFrameOpen(pavi, NULL); // Create The PGETFRAME Using Our Request Mode if (pgf==NULL) { // An Error Occurred Opening The Frame MessageBox (HWND_DESKTOP, "Failed To Open The AVI Frame", "Error", MB_OK | MB_ICONEXCLAMATION); } https://stackoverflow.com/questions/39059959/vfw-avistreamgetframeopen-returns-null carve.avi
  4. Hi, first post here! Been reading png files in SDL and using them as textures... Now, would like to include in my game 2 short videos made in Blender, in dvi and mp4 formats. Went over NeHe lesson 35 but when I try to read the dvi file, it gives null pointer for lpbi, see below. Is it possible to include video files in OpenGL and how, please? ;-))) void GrabAVIFrame(int frame) // Grabs A Frame From The Stream { LPBITMAPINFOHEADER lpbi; // Holds The Bitmap Header Information lpbi = (LPBITMAPINFOHEADER)AVIStreamGetFrame(pgf, frame); // Grab Data From The AVI Stream pdata=(char *)lpbi+lpbi->biSize+lpbi->biClrUsed * sizeof(RGBQUAD); // Pointer To Data Returned By AVIStreamGetFrame // Convert Data To Requested Bitmap Format DrawDibDraw (hdd, hdc, 0, 0, 256, 256, lpbi, pdata, 0, 0, width, height, 0); flipIt(data); // Swap The Red And Blue Bytes (GL Compatability) // Update The Texture glTexSubImage2D (GL_TEXTURE_2D, 0, 0, 0, 256, 256, GL_RGB, GL_UNSIGNED_BYTE, data); }
