  • Displaying YUV420 data using Opengles shader is too slow

    28 novembre 2012, par user1278982

    I have a child thread called A to decode video using ffmpeg on iPhone 3GS, another thread called B to display yuv data, in thread B, I used glSubTexImage2D to upload Y U V textures, and then convert yuv data to RGB in shader, but the frame rate in the decode thread is only 15fps.Why ?

    Update :
    The frame size is 720 * 576.
    I also found something interesting that if I didn't start the thread displaying the YUV data, the frame rate calculated in the decode thread is 22 fps,otherwise 15 fps.So I think that my displaying method must be inefficient.the code as below.

    I have a callback in the decode thread :

    typedef struct _DVDVideoPicture
    
{
    
   char *plane[4];
    
   int iLineSize[4];
    
}DVDVideoPicture;
    

    
void YUVCallBack(void *pYUVData, void *pContext)
    
{
    
   VideoView *view = (VideoView *)pContext;
    
   [view.glView copyYUVData:(DVDVideoPicture *)pData];
    
   [view calculateFrameRate];
    
}

    The copyYUVData method extract the y u v planes separately. The following is displaying thread method.

  • FFmpeg flags for second input / audio source

    10 juillet 2015, par LouisK

    Reading FFmpeg docs it seems it’s totally possible to use two streams of buffer data to transcode. Is this wrong ?

    I’m trying to use 2 streamed inputs via a child process in node.js, but only have 1 working.

    Only appending 1 -i, 1 source piped in works for video only or an already combined stream :
    ffmpeg -i - -f mp4 -movflags frag_keyframe+faststart pipe:1

    two inputs, 2 piped sources fails :
    ffmpeg -i - -map 0:v -i - -map 0:a -ar 44100 -ac 2 -ab 96000 -f mp4 -movflags frag_keyframe+faststart pipe:1 pipe:2

    gives : Error opening input files : Invalid argument — what argument is invalid ? Is the data I’m sending it an issue ?
