video frames render slow using opengl and ffmpeg in iphone
17 février 2012, par resident_I'm developing an video player for iPhone. I'm using ffmpeg libraries to decode frames of video and I'm using opengl 2.0 to render the frames to the screen.
But my app is very slow render the frames and some videos played slowly.
I have played AVI, MOV, FLV, MP4 and WMV, and only several AVI files are correct played.
I don't have much idea of ffmpeg and opengl, and I have used a tutorials and examples until now. But I think that the problem can be two things :
-
The render method is very slowly. I don't use correctly the glTexSubImage2D function.
-
I don't scale the frames correctly. I don't use correctly the sws_getContext function.
I'm here parts of my code, to see if anyone can help me.
So I use sws_getContext
ctx->p_sws_ctx = sws_getContext(ctx->p_video_ctx->width,
ctx->p_video_ctx->height,
ctx->p_video_ctx->pix_fmt,
ctx->p_video_ctx->width,
ctx->p_video_ctx->height,
PIX_FMT_RGB565, SWS_FAST_BILINEAR, NULL, NULL, NULL);
// Framebuffer for RGB data
ctx->p_frame_buffer = malloc(avpicture_get_size(PIX_FMT_RGB565,
ctx->p_video_ctx->width,
ctx->p_video_ctx->height));
avpicture_fill((AVPicture*)ctx->p_picture_rgb, ctx->p_frame_buffer, PIX_FMT_RGB565,
ctx->p_video_ctx->width,
ctx->p_video_ctx->height);My render method of opengl 2.0
- (void) render: (uint8_t*) buffer
[EAGLContext setCurrentContext:context] ;
glBindFramebuffer(GL_FRAMEBUFFER, defaultFramebuffer);
glViewport(0, 0, backingWidth, backingHeight);
glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
// OpenGL loads textures lazily so accessing the buffer is deferred until draw; notify
// the movie player that we're done with the texture after glDrawArrays.
glTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, mFrameW, mFrameH, GL_RGB,GL_UNSIGNED_SHORT_5_6_5, buffer);
glDrawArrays(GL_TRIANGLE_STRIP, 0, 4);
[moviePlayerDelegate bufferDone];
glBindRenderbuffer(GL_RENDERBUFFER, colorRenderbuffer);
[context presentRenderbuffer:GL_RENDERBUFFER];Someone, can I Help me ?
Thanks,
