That causes flickering and invisibility of one or the other status line. As compromise set ffplay log level to warning, so it doesn't show the status line. The user is usually testing ffmpeg command lines and want's a preview of the result. This way the user can see the ffmpeg output and still see errors and warnings from ffplay, should they occur. --- libavdevice/opengl_enc.c | 2 +- libavdevice/sdl2.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/libavdevice/opengl_enc.c b/libavdevice/opengl_enc.c index 6f7a30ff9e..c50d02870a 100644 --- a/libavdevice/opengl_enc.c +++ b/libavdevice/opengl_enc.c @@ -1067,7 +1067,7 @@ static av_cold int opengl_write_header(AVFormatContext *h) av_log(opengl, AV_LOG_WARNING, "The opengl output device is deprecated due to being fundamentally incompatible with libavformat API.
