How to increase performance of bitmap drawing on Android
20 avril 2012, par vitakotI created a movie player based on FFmpeg. It works fine. The decoding is quite fast, on LG P970 (Cortex A8 with Neon) I have an average 70 fps with 640 x 424 resolution video stream including YUV2RGB conversion. However, there is one bottleneck. It is drawing on Canvas.
I use jnigraphics native library to fill picture data into the bitmap in the native side and then I draw this bitmap on Canvas in SurfaceView. It is quite simple and common approach, but the drawing takes 44 ms for bitmap with 640 x 424 resolution which reduces fps to 23 and makes this technique unusable... It takes a lot more then the whole A/V frame decoding !
Is there any method how to draw bitmaps significantly faster ? I would prefer to render completely in the native code using OpenGLES 2, but I have read it also could be slow. So what now ?...
How can I render bitmaps as fast as possible ?

YUV to RGB by Shader on iPhone
27 octobre 2012, par user1333656Currently 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. -
Getting Error during executin native android code
3 avril 2013, par dilipkaklotarError on my console
bash : cannot set terminal process group (-1) : Inappropriate ioctl for device
bash : no job control in this shell
Your group is currently "mkpasswd". This indicates that your
gid is not in /etc/group and your uid is not in /etc/passwd.The /etc/passwd (and possibly /etc/group) files should be rebuilt.
See the man pages for mkpasswd and mkgroup then, for example, runmkpasswd -l [-d] > /etc/passwd
mkgroup -l [-d] > /etc/groupNote that the -d switch is necessary for domain users.
