  • why cannt render video frame via openGLES2 with Android NDK

    15 août 2013, par wolfz

    i made a bin code with NDK to get video frames by ffmpeg decoding ,and rendered to opengles ,but the screen had nothing changed ,it still displayed the launcher.

    my render code as below :

    int m_rgbBufferSize = pPicture->iDisplayWidth*pPicture->iDisplayHeight*4;
    m_rgbBuffer = new unsigned char[m_rgbBufferSize];

    struct SwsContext *m_sw_context=NULL;
    m_sw_context = m_dllSwScale.sws_getCachedContext(m_sw_context,
                                                     pPicture->iWidth, pPicture->iHeight, PIX_FMT_YUV420P,
                                                     pPicture->iWidth, pPicture->iHeight, PIX_FMT_RGBA,
                                                     SWS_FAST_BILINEAR, NULL, NULL, NULL);

    uint8_t *psrc[] = { pPicture->data[0], pPicture->data[1], pPicture->data[2], 0 };
    int srcStride[] = { pPicture->iLineSize[0], pPicture->iLineSize[1], pPicture->iLineSize[2], 0 };
    uint8_t *dst[]  = { m_rgbBuffer, 0, 0, 0 };
    int dstStride[] = { pPicture->iDisplayWidth*4, 0, 0, 0 };
    m_dllSwScale.sws_scale(m_sw_context, psrc, srcStride, 0, pPicture->iDisplayHeight, dst, dstStride);
    //LOGV("swscale OK");
    glEnable(GL_TEXTURE_2D);
    glPixelStorei(GL_UNPACK_ALIGNMENT,1);
    if(textureid == 0)
       glGenTextures(1, &textureid);
    glActiveTexture(GL_TEXTURE2);
    glBindTexture(GL_TEXTURE_2D, textureid);
    glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0,
                   pPicture->iDisplayWidth, pPicture->iDisplayHeight, GL_RGBA, GL_UNSIGNED_BYTE, m_rgbBuffer);

    why does nothing to display ? should I use abk not bin file to run ?

  • Programmatically get non-overlapping images from MP4

    16 novembre 2019, par Carlos F

    My ultimate goal is to get meaningful snapshots from MP4 videos that are either 30 min or 1 hour long. "Meaningful" is a bit ambitious, so I have simplified my requirements.

    The image should be crisp - non-overlapping, and ideally not blurry. Initially, I thought getting a keyframe would work, but I had no idea that keyframes could have overlapping images embedded in them like this :enter image description here

    Of course, some keyframe images look like this and those are much better :

    enter image description here

    I was wondering if someone might have source code to :

    Take a sequence of say 10-15 continuous keyframes (jpg or png) and identify the best keyframe from all of them.

    This must happen entirely programmatically. I found this paper : http://research.microsoft.com/pubs/68802/blur_determination_compressed.pdf

    and felt that I could "rank" a few images based on the above paper, but then I was dissuaded by this link : Extracting DCT coefficients from encoded images and video given that my source video is an MP4. Of course, this confuses me because the input into the system is just a sequence of jpg images.

    Another link that is interesting is :

    Detection of Blur in Images/Video sequences

    However, I am not sure if this will work for "overlapping" images.
