I do not have any Fire devices (for reasons), but on
other<br>
forums it has been stated that the 4K Max (but not the
4K)<br>
has some issues (with MPEG2 decode) that require one<br>
to use software playback for (at least) some types of
content.<br>

<div>That meshes with what I've found. I set the Max to
OpenGL 4CPUs Low Quality Deinterlace and the picture
is great if you don't skip. In fact on the regular
FireTV 4K I do the same and it's a little poorer
picture, but usable. However, You can skip all you
want.</div>

<div>I did some testing on the FireTV 4K Max this morning and
This included Android Medicodec. MediaCodec is
definitely worse on MPEG2 content. The Max will not play a
video with sound unless the Audio Read Ahead is at least
800. If you try to skip forward it will fail on the first
skip. With Read Ahead set to 1000, you might get 2 skips,
with Read Ahead at 2000, you might get 2 or 3 before the FPS
goes to 40 or 50 instead of 30. </div>

</div>
<div>I did a factory reset on the MAX and only install
mythfrontend and the results were the same. All of this was
on the V32 version.</div>
<div><br>
</div>
<div>If there is something wrong with my MAX it doesn not
affect playing Prime Video at 4K or Leanfront on v32
content.</div>
<div><br>
</div>
<div>Peter, I can capture any log you want or you can email me
directly and we can see how I can loan you my Max for
testing?</div>
<div><br>
</div>
<div>I'm going to switch back to my FireTV 4K regular and
continue testing there. I also have a Shield TV (2017) to
test with.</div>

<p>Actually I am not using mythfrontend on android at the moment,
just building it and posting the package when necessary. There was
some problem with the ffmpeg interface to mediacodec that affected
mpeg2 on the fire stick. I do not remember if that was ever
resolved. Perhaps there are other problems with it now. Since
leanfront works fine, mediacodec must be ok. Leanfront only uses
mediacodec, it does not have a software decode method for video.</p>
<p>The problem with skipping on mythfrontend - does if affect
recordings and videos the same? Recordings have a seek table on
the database to speed up jumps, videos do not (unless you have
done something to delete, change or create a seek table). When
there is a seek table mythfrontend uses that to skip. When there
is no seek table it uses ffmpeg to skip.<br>
</p>
<p>At some point I may get a fire stick 4K Max but I do not have
time to deal with it now.</p>
