Dragon player behaves differently on the same video files. What to use? Vlc is not an option.

Dragon player behaves differently on the same video file.
I request playing the file 0405.mp4.
1. It can play the file as expected.
2. It can't play the file. In this case , it just start the process. After 5-25 second process is terminated without any video playing.

After some time it can play the same file normally. It can switch its behaviour in any direction at any time.

Probably your videocard supports just single VAAPI or VDPAU or Xv(MC) surface, so one video at the time.
vlc would fall back to less performant playback in case the good one seems unavailable.

But I attempt to start only one video at the time. Audio is present, video is absent. That's the issue.

So you are missing codecs.

Still get this error while opening VLC

No suitable decoder module:
VLC does not support the audio or video format "h264". Unfortunately there is no way for you to fix this.

However there is an audio track is playing ok

vlc does not use gstreamer. that is for dragon player.
official VLC build (one in rpmfusion as linked from videolan.org) comes with H264 support (aka BluRay encoding).
