I've been playing with Lakka (game emu focused) which I
think is also based on Kodi. It looks like Kodi charges
extra for MPEG decoding. Is this the case? Needed for Myth
playback on Raspberry Pi 1/2?

<div>I don't think it is Kodi that is charging extra for
mpeg2, but to get a license on the Rpi for hardware
acceleration of mpeg2 you have to pay a license fee (I
assume to Broadcom or to whoever does its graphics
coprocessor). <br>

What I'd like to know is how is 1080p playback in the MythTV tool on
Kodi on the Raspberry Pi? Is the hardware acceleration add-on
needed?</div></blockquote><div><br></div></div></div><div>Playback is great and yes, you do need/want the hardware acceleration if you playback HD mpeg2 content. If everything is mpeg 4, or only SD for mpeg2 (dvd's) than you shouldn't need it. there is also a license for VC-1 if you need that.</div><div><br></div><div>Both together will cost you about $5 USD. A small price for a huge performance jump. I was able to play content un-accelerated, but it wasn't smooth.</div><div><br></div><div>However if you transcode all your HD content to mpeg-4, or you use a device that records HD in mpeg-4 you can probably pass on them and save yourself $5.</div><div><br></div><div>Note: I have no experience with the rPi... just the rPi2. I suspect that the standard rPi may struggle to decode even SD mpeg 2... but the rPi2 plays it just fine in software (no license).</div></div></div></div></blockquote><div><br></div><div>The raspberry pi and the raspberry pi2 have the same GPU.</div><div><br></div><div>The GPU decodes h.264 in hardware out of the box.
