All three work fine (on Windows 7 x64).
Generally when a media file plays, but you can only see the video OR hear the
audio the problem is a codec issue.
If it were a media player issue the media would not play at all.
Since the media plays and you can hear the sound I suspect a codec issue on
your computer.
It appears that LibreOffice tries to determine which codecs are supported on
each OS.
But it does not always get it right, and some format/codec combinations do not
work.
Each OS does not support all codecs which are allowed in a particular format
(MP4, MPEG, WEBM, etc.)
So issue may be a codec issue on your particular computer, and/or a LibreOffice
format/codec combo support guessing issue.
I tested your original file and some recoded different format/codec
combinations.
- Original MPG - MPEG-2, MP2
(MPG format, MPEG-2 video codec, MP2 audio codec)
Works fine for me in LO
Also tested in Windows Media Player - works fine
- MP4 - MPEG-2, MP2
(I direct-copied the streams into an MP4 container, not recoded)
Video stream plays, audio stream does not play in LO
Also tested in Windows Media Player - no sound, video plays
So my Win7 does not support MP2 audio in an MP4 container.
- MP4 - AVC-x264, AAC
(recoded into MP4 container, AVC-x264 video codec, AAC audio codec)
Plays fine in LO
Plays fine in Windows Media Player
- WEBM - VP8, OPUS
LO says "The format of the selected file is not supported."
Win7 does not support this natively.
- WEBM - VP8, Vorbis
LO says "The format of the selected file is not supported."
Win7 does not support this natively.
- WMV - WMV2, WMA2
(Windows Media Video format, WMV2(8) video codec, WMA2(8) audio codec)
Plays fine in LO
Plays fine in Windows Media Player
If you want I can attach some of the test files.
There was another Win10 user in the Ask LO forum with a similar issue.
He had a video stop playing in LO on one Win10 machine,
and still played fine on a different Win10 machine.
He fixed it with a codec repair tool.
So something damaged his codec configuration.
Encoding applications, media players, media editors, etc. - all may install
codecs.
There are now two testers with no issues, and two testers with playback issues.
The fix may be related to codecs on your machine.
Does the original video play in Windows Media Player on your machine?
Another option may be to use a more popular format/codec combination.
