sometimes when I play a video at the beginning ffplay resizes window from
640x480 to actual
resolution of the video because code enters for first frame to "else"
statement
(the rest of the 4 queued frames are displayed with correct size under
(vp->width) statement),
so if possible I would like to see this unnecessary resize (flickering)
for first frame removed.
this seems to remove (or reduce) the problem, but the first frame is not
displayed at all
(so it fails for images)
{{{
display:
/* display picture */
- if (!display_disable && is->show_mode == SHOW_MODE_VIDEO)
- video_display(is);
pictq_next_picture(is);
+ if (!display_disable && is->show_mode == SHOW_MODE_VIDEO)
+ video_display(is);
if (is->step && !is->paused)
stream_toggle_pause(is);
}}}
No FFplay's output since it happens randomly with various video files
(sometimes easier to reproduce when -lowres option is enabled)
