I had a look at the above channel. xine reports a ratio of 13636.
But the current zoom code in input_vdr.c doesn't consider this to
be 4:3. Please replace the function adjust_zoom() by the
following code:
static void adjust_zoom(vdr_input_plugin_t *this)
{
pthread_mutex_lock(&this->adjust_zoom_lock);
if (this->image4_3_zoom_x && this->image4_3_zoom_y
&& this->image16_9_zoom_x && this->image16_9_zoom_y)
{
int ratio = (int)(10000 * this->frame_size.r + 0.5);
int matches4_3 = abs(ratio - 13333);
int matches16_9 = abs(ratio - 17778);
/* fprintf(stderr, "ratio: %d\n", ratio); */
if (matches4_3 < matches16_9)
{
xine_set_param(this->stream, XINE_PARAM_VO_ZOOM_X,
this->image4_3_zoom_x);
xine_set_param(this->stream, XINE_PARAM_VO_ZOOM_Y,
this->image4_3_zoom_y);
}
else
{
xine_set_param(this->stream, XINE_PARAM_VO_ZOOM_X,
this->image16_9_zoom_x);
xine_set_param(this->stream, XINE_PARAM_VO_ZOOM_Y,
this->image16_9_zoom_y);
}
}
pthread_mutex_unlock(&this->adjust_zoom_lock);
}
Bye.
