So popcornmix came up with a fix for this over at the RPi LibreElec thread: LibreELEC Testbuilds for RaspberryPi (Kodi 17.0)
Add the following to advancedsetting.xml
<advancedsettings>
<omx>
<omxdecodestartwithvalidframe>0</omxdecodestartwithvalidframe>
</omx>
</advancedsettings>Worked for me on the Olympics HD streams. Just in time for the closing ceremony.
I'm glad this isn't just me.
I think there's something CODEC related that the RPi hardware acceleration doesn't like because if you turn OMXplayer or MMAL off (in Settings/Player/Video) the affected streams will actually play albeit very slowly.
EDIT: Here is the CODEC information from the stream that won't play
