Я создал файл mp4 с помощью gstreamer.
gst-launch-1.0 videotestsrc num-buffers=10 ! "video/x-raw, format=(string)NV12, width=(int)1280, height=(int)720, framerate=(fraction)30/1" ! videoconvert ! avenc_mpeg4 ! avmux_mp4 ! filesink location=/tmp/test.mp4
И я могу воспроизвести его с помощью Mplayer, VL C et c. Но я не могу воспроизвести его на Windows Media Player.
Я установил флажок MP4. но кажется, что у него нет проблем. Как я могу попробовать другой способ?
