android opengl版本太低,如何提高android中的opengl es显示性能

我正在努力提高Android视频会议项目的视频显示效率.视频显示以本机opengl代码实现. opengl代码以opengl版本1的原生实现.下面给出的代码用于显示视频的每个帧.

int ofi_vc_video_display::render_video_frame(unsigned char *frame_buffer)

{

// Check the frame is available or not. If available display the frame.

if (frame_buffer != NULL){

// Clear the screen buffers.

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

// Bind the frame data to the texture.

glTexSubImage2D(GL_TEXTURE_2D,

0,

0,

0,

frame_width,

frame_height,

GL_RGB,

GL_UNSIGNED_BYTE,

frame_buffer);

// Check for the error status.

while ((gl_error_status=glGetError()) != GL_NO_ERROR) {

error_status = gl_error_status;

}

// Transform and rotate the texture.

glMatrixMode(GL_TEXTURE);

glLoadIdentity();

glTranslatef(0
