My code like that:

 

 

bool Player::InitPipe()

{

    if (!is_init_){

        /* initialization */

        gst_init (NULL, NULL);

        printf("gst_init\n");

        is_init_ = true;

    }

 

 

    if (NULL == pipeline_) {

        /* create elements */

        GstElement *fakesink;

        pipeline_ = gst_pipeline_new ("pipeline");

        bus_ = gst_pipeline_get_bus (GST_PIPELINE (pipeline_));

        gst_object_unref (bus_);

 

 

        /* create elements */

        playbin_ = gst_element_factory_make ("playbin2", "bin");

        fakesink  = gst_element_factory_make ("fakesink", "videosink");

        printf("playbin_ = [%p], fakesink = [%p]\n", playbin_, fakesink);

        if (!playbin_ || !fakesink) {

            g_print ("one element could not be found \n");

            return false;

        }

 

 

        /* configure elements */

        g_object_set (G_OBJECT (fakesink), "sync", TRUE, "signal-handoffs", TRUE, NULL);

        g_signal_connect (fakesink, "handoff", G_CALLBACK (CB_Handoff), this);

 

 

        g_object_set (G_OBJECT (playbin_), "video-sink", fakesink, NULL);

        gst_bin_add (GST_BIN (pipeline_), playbin_);

    }

    return true;

}

 

 

 

 

void Player::CB_Handoff(GstElement *object, GstBuffer *buf, GstPad *pad, Player *pThis)

{

    if (pThis != NULL) {

        gst_buffer_ref (buf);

        if (pThis->picture_session_ == NULL) {

            GstStructure *s;

            GstCaps *caps;

            caps = GST_BUFFER_CAPS (buf);

            s = gst_caps_get_structure (caps, 0);

            gst_structure_get_int (s, "width", &(pThis->width_));

            gst_structure_get_int (s, "height", &(pThis->height_));

 

 

            guint32 fourcc;

            gst_structure_get_fourcc (s, "format", &fourcc);

            pThis->format_ = gst_gl_vivante_get_gl_format(gst_video_format_from_fourcc(fourcc));

            const GValue *value = gst_structure_get_value(s, "format");

            printf("format value: %s.\n", g_strdup_value_contents(value));

            pThis->buf_size_ = buf->size;

            pThis->InitRender();

        }

        UpdateTextureData(pThis->render_id_, pThis->picture_session_, GST_BUFFER_DATA(buf), pThis->buf_size_, pThis->format_);

        gst_buffer_unref (buf);

    }

}

 

 

 

 

 

 

InitRender like that:

char *GetTexturePtr(GLuint texture, int width, int height, int format, void* data_ptr[])

{

    if (texture == 0) {

        return NULL;

    }

 

 

    char *ptr = NULL;

    glBindTexture(GL_TEXTURE_2D, texture);

    if (glGetError() != GL_NO_ERROR) {

        printf("\n\n[%s:%s:%d]glErrno = [%d]\n\n", __FILE__, __FUNCTION__, __LINE__, glGetError());

  return NULL;

  }

    if (-1 == format) {

        format = GL_BGRA_EXT;

    }

    glTexDirectVIV(GL_TEXTURE_2D, width, height, format, (GLvoid **)data_ptr);

    if (glGetError() != GL_NO_ERROR) {

    printf("\n\n[%s:%s:%d]glErrno = [%d]\n\n", __FILE__, __FUNCTION__, __LINE__, glGetError());

    return NULL;

    }

    return ptr;

}

 

 

UpdateTextureData like that:

void UpdateTextureData(GLuint texture, void *texPtr[], char *data, int w, int h, int format)

{

    if ((texture == 0)/* || (texPtr == NULL)*/ || (data == NULL)/* || (dataSize < 1)*/) {

        printf("exit:[%s:%s:%d]\n", __FILE__, __FUNCTION__, __LINE__);

        return ;

    }

 

    glBindTexture(GL_TEXTURE_2D, texture);

    if (glGetError() != GL_NO_ERROR) {

        printf("\n\n[%s:%s:%d]glErrno = [%d]\n\n", __FILE__, __FUNCTION__, __LINE__, glGetError());

        return ;

    }

   

    if (-1 == format) {

  format = GL_BGRA_EXT;

  }

 

 

  glTexDirectVIV(GL_TEXTURE_2D, w, h, format, (GLvoid **)texPtr);

  if (glGetError() != GL_NO_ERROR) {

  printf("\n\n[%s:%s:%d]glErrno = [%d]\n\n", __FILE__, __FUNCTION__, __LINE__, glGetError());

  return ;

  }

 

 

    copy_data_to_gpu(format, data, texPtr, w, h);

 

 

    glTexDirectInvalidateVIV(GL_TEXTURE_2D);

    if (glGetError() != GL_NO_ERROR) {printf("error!\n");}

}
