  • YUV to RGB by Shader on iPhone

    27 octobre 2012, par user1333656

    Currently I am developing a video player using FFMPEG.
    I'm trying to convert YUV420P to RGB by Shader to reduce performance hit and I could see it works fine. The problem is caused when I try to change image size.

    Case 1. YUV to RGB is perfect. but the image is not exactly fit to Texture Bounds.
    For example, if i play 640x360 video, right (640-512) part is cropped and bottom (512-360) is filled with green colored rectangle.

    FRAME_X=512; //This is texture size
    
FRAME_Y=512;
    

    
    avpicture_fill((AVPicture *) f, [currentVideoBuffer.data mutableBytes],
    
               enc->pix_fmt,
    
               FRAME_X, FRAME_Y);
    

    
    av_picture_copy((AVPicture *) f, (AVPicture *) avFrame,
    
                enc->pix_fmt,
    
                enc->width, enc->height);

    ....

    int yuvWidth= FRAME_X ;
    
int  yuvHeight= FRAME_Y;
    
glBindTexture ( GL_TEXTURE_2D, textureIdY );
    
glTexImage2D(GL_TEXTURE_2D, 0, GL_LUMINANCE, 
    
yuvWidth, yuvHeight, 0, GL_LUMINANCE, GL_UNSIGNED_BYTE, y_channel);
    

    

    
glBindTexture ( GL_TEXTURE_2D, textureIdU );
    
glTexImage2D(GL_TEXTURE_2D, 0, GL_LUMINANCE,
    
yuvWidth/2, yuvHeight/2, 0, GL_LUMINANCE, GL_UNSIGNED_BYTE, u_channel);
    

    
glBindTexture ( GL_TEXTURE_2D, textureIdV );
    
glTexImage2D(GL_TEXTURE_2D, 0, GL_LUMINANCE, 
    
yuvWidth/2, yuvHeight/2, 0, GL_LUMINANCE, GL_UNSIGNED_BYTE, v_channel);

    Case 2. If i set actual image size to texture size, then image is exactly fit to texture but the color of image is a little bit strange. It has too much green color.

    Does anybody give me some clues for this ??
    Thanks in advance.

  • How to convert iphone's caf to ogg on ubuntu

    24 novembre 2012, par Amure Pinho - Syncmobile

    i really need your support to solve that problem :

    We developed an iOS application that sends a sound file to our server and then, we share this audio.

    The problem is we didnt find any solution to convert the audio inside the iOS.

    We tought : Ok, thats a problem, but we can still convert the audio in the server right ?

    We are trying to make this using afconvert, ffmpeg but with no sucess.

    Do you have any basic guide or hint so we can write this in our server application and convert all the .CAF files to another format like OGG or MP3 ?

    Thanks a lot !
