  • Converting FFmpeg frame to OpenGL ES texture

    10 juillet 2015, par joe

    I’m trying to convert from a video using FFmpeg to an OpenGL ES texture in jni, but all that I get is a black texture. I have output the OpenGL with the glGetError(), but there is no error.

    Here is my code :

    void* pixels;
    
int err;
    
int i;
    
int frameFinished = 0;
    
AVPacket packet;
    
static struct SwsContext *img_convert_ctx;
    
static struct SwsContext *scale_context = NULL;
    
int64_t seek_target;
    

    
 int target_width = 320;
    
 int target_height = 240;
    
 GLenum error = GL_NO_ERROR;
    
 sws_freeContext(img_convert_ctx);  
    

    
i = 0;
    
while((i==0) && (av_read_frame(pFormatCtx, &packet)>=0)) {
    
        if(packet.stream_index==videoStream) {
    
        avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
    

    
        if(frameFinished) {
    
            LOGI("packet pts %llu", packet.pts);
    
            img_convert_ctx = sws_getContext(pCodecCtx->width, pCodecCtx->height, 
    
                   pCodecCtx->pix_fmt, 
    
                   target_width, target_height, PIX_FMT_RGB24, SWS_BICUBIC, 
    
                   NULL, NULL, NULL);
    
            if(img_convert_ctx == NULL) {
    
                LOGE("could not initialize conversion context\n");
    
                return;
    
            }
    
                sws_scale(img_convert_ctx, (const uint8_t* const*)pFrame->data, pFrame->linesize, 0, pCodecCtx->height, pFrameRGB->data, pFrameRGB->linesize);
    
                LOGI("sws_scale");
    

    
                videoTextures = new Texture*[1];
    
                videoTextures[0]->mWidth = 256; //(unsigned)pCodecCtx->width;
    
                videoTextures[0]->mHeight = 256; //(unsigned)pCodecCtx->height;
    
                videoTextures[0]->mData = pFrameRGB->data[0];
    

    
                glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
    

    
                glGenTextures(1, &(videoTextures[0]->mTextureID));
    
                glBindTexture(GL_TEXTURE_2D, videoTextures[0]->mTextureID);
    
                glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); 
    
                glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    

    
                if(0 == got_texture)
    
                {
    
                    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, videoTextures[0]->mWidth, videoTextures[0]->mHeight, 0, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)videoTextures[0]->mData);
    

    
                    glTexSubImage2D(GL_TEXTURE_2D, 0, 0,0, videoTextures[0]->mWidth, videoTextures[0]->mHeight, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)videoTextures[0]->mData);
    
                }else
    
                {
    
                    glTexSubImage2D(GL_TEXTURE_2D, 0, 0,0, videoTextures[0]->mWidth, videoTextures[0]->mHeight, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)videoTextures[0]->mData);
    

    
                }
    

    
                i = 1;
    
                error = glGetError();
    
                if( error != GL_NO_ERROR ) {
    
                    LOGE("couldn't create texture!!");
    
                       switch (error) {
    
                        case GL_INVALID_ENUM:
    
                        LOGE("GL Error: Enum argument is out of range");
    
                        break;
    
                        case GL_INVALID_VALUE:
    
                            LOGE("GL Error: Numeric value is out of range");
    
                        break;
    
                        case GL_INVALID_OPERATION:
    
                            LOGE("GL Error: Operation illegal in current state");
    
                        break;
    
                        case GL_OUT_OF_MEMORY:
    
                            LOGE("GL Error: Not enough memory to execute command");
    
                        break;
    
                        default:
    
                            break;
    
                       }
    
                }
    
        }
    
    }
    
    av_free_packet(&packet);
    
}

    I have succeeded in changing pFrameRGB to a java bitmap， but I just want to change it to a texture in the c code.

    Edit1 I have output the Texture ID, it is 0 ; could texture ID be zero ? I changed my code
    but it always be zero.

    Edit2
    the Texture display, but it is a mess.

  • Mixing audio and video with ffmpeg [closed]

    3 septembre 2013, par Narendra DroidWorm

    I am having an mp4 video (without audio), to which I want to add music using ffmpeg, and also want the output video to be of the same length as the input video.

    But, as a result, I am getting an video merged with audio, but consuming a little more time (abt 1-2 seconds) in the start with a black screen.

    I am using the following command for my desired output.

    ffmpeg -i audio.mp3 -i video.avi -acodec copy -vcodec copy output.avi

    Please suggest, what modifications should I do to get my desired output.

  • convert exr filesequence with ffmpeg and x264 [closed]

    29 novembre 2012, par user1863947

    When i convert a exr sequence into quicktime mov file using ffmpeg and x264 codec it codes the video but in quicktime player and windows media player its just black ! but when i open it up with vlc i can see the image and it looks fine. When i try the same thing with a jpg sequence instead of exr it works perfect ! does anyone have an idea what that could be ?

    here is my ffmpeg code :

    ffmpeg -y -i C:/seq_v001.%04d.exr -c:v libx264 -preset slow -crf 17 C:/out.mov

    Here is the console output :
