Well it looks like this thread didn't get much traction!
I have a solution that seems to work alright. Here is some explanation. It might not all be completely correct or apply to other peoples situations but i figure spreading the knowledge is better than no one knowing what the options are.
Enigma2 media players are all based on the Gstreamer framework. The FFMPEG framework can do a better job of playing some media types such as internet streams and (I found) .ts files. FFMPEG is not a regular part of Enigma2. You have to install it along with a different media player and then activate that new player using a third tool.
From a command line window to the ZGemma install ffmpeg, exteplayer3 and serviceapp:
# opkg update
# opkg remove enigma2-plugin-systemplugins-serviceapp exteplayer3 ffmpeg
# opkg install ffmpeg exteplayer3 enigma2-plugin-systemplugins-serviceapp
Configure ServiceApp to make exteplayer3 the default media player in enigma2:
Now from OpenVix… Menu > Setup > System > ServiceApp
Enigma2 playback system: serviceapp
Player: exteplayer3
I left all the options underneath unchanged except "Auto turn on subtitles" (I set this to false)
Update the advancedsettings.xml so kodi knows what the enigma2 default media player is:
/usr/share/kodi/system/advancedsettings.xml
Change... <defaultplayer>E2Player</defaultplayer>
To
<defaultplayer>exteplayer3</defaultplayer>
Update the Kodi SYSTEM playercorefactory.xml file so Kodi knows what the enigma2 default media player is:
/usr/share/kodi/system/playercorefactory.xml
Change… <player name="E2Player" type="Enigma2Player" audio="true" video="true">
To
<player name="exteplayer3" type="Enigma2Player" audio="true" video="true">
Now reboot the Zgemma.
Controlling playback of .ts files played through Kodi
When watching a movie from Kodi you use the same controls to pause/play/stop/skipforward the movie as though you were watching the movie from OpenVix.
You don't get nice Kodi style on screen controls as you do in other dedicated Kodi devices or OSs such as OSMC.
The fastforward >| and rewind <| buttons don't seem to work when playing a movie from Kodi but they DO work when playing the same movie from OpenVix.
The lack of ffwrd and rewind is a known limitation of exteplayer3.
A workaround is to simply skip forward and back by a fixed number of seconds using the number buttons on the remote: 1/3=15 secs, 4/6=60 secs, 7/9=300 secs.
These durations can be changed in: OpenVix Menu > Setup > Recordings, playback & timeshift > Recording & Playback > Custom skip time for.....
You can also long press the left and right arrow buttons (either side of the OK button) and then additional presses skip forward or back by a time that is configurable in:
OpenVix Menu > Setup > Recordings, playback & timeshift > Recording & Playback > Seekbar sensibility
I found that 1 = 9 seconds and 10 is 65 seconds in Kodi,
After I did all of this, I am able to play movie recordings (.ts files) I made in OpenVix on the ZGemma H7S though the Kodi plugin. So far Kodi 18.7 in OpenVix 5.3 on the ZGemma H7S seems to work ok for this purpose.
Hope this helps someone,
