Sony Android TV 6.0.1 - Video playback is stuttering KD-55XD8005 / KD-55XE8505
So here is another one with the mpiet sample. [LOG] And this again is how playback looks like.
Quote: Yes it fixes the 25/50 stutter on shield, unfortunately mpiet samples play fine on all f my devices.
Funny that the 1080p25 sample plays fine on Sony ATV with both, new and old method, while mpiet's sample stutters with both.

Something seems to be wrong with my log. There is no useful information in there. Enabled only component-specific logging together with the Video component..

[EDIT]
@popy's log isn't more useful either though.

Here is another one with also debug logging enabled. Thought that had to be enabled anyway..

Thx for the hint regarding debugging. Will also make a log later when I am at home again.

That's actually how @peak3d wanted it to be. But I can't see any useful information in there...

Hmm, I got interested while reading this topic and wanted to see if this was also an issue on my Philips TV. And indeed it was with the "amcs_sync_sample (noaudio).mkv" file. But when I had a look at the actual clip, it's a bit of a strange one. To me it looks like it's p23.976 content put in a p25 MKV container...which doesn't make any sense...

So I remuxed the clip to a real p23.976 container and created a second clip into a p25 container (of course resulting in this clip playing slightly faster). Both of the clips played fine on my Philips TV (internal player and Kodi).

To be honest I don't think Kodi should be modified to handle these faulty clips. Instead they should be muxed correctly.

You are absolutely right. When parsing SPS of the H.264 ES, you will indeed find out that it is 23.976fps.

Hey guys, can you please explain how to remux my problematic video's to see if the issue is also in my case the wrong muxed videos?

PS: wouldn't it be good if kodi would take the Infos from the FixedFramerate field? Don't get me wrong, I don't understand much of these, just an idea

Thx pOpY

You can do so by using mkvtoolnix for example if source file is mkv:

I actually don't know why Kodi gets distracted by container information. Information within elemantary streams (timestamps) should be fine.

i can confirm that remuxing my problematic video with MKV Toolnix and setting the metadata fps to 24000/1001 fixed the playback issue in kodi on my android tv.
Like @CiNcH already mentiond, it seems kodi gets distracted by the container metadata information.

Here are the ourputs from mediainfo from booth videos.
@peak3d Maybe you could look into this? (kodi should take the infos from the stream rather than from Metadata, shouldn't it? )

Original, with set 25fps, but video stream is 24000/1001 (24p):

For me the 25fps is correct, some instance upsampled the video from 23.9 -> 25.
Not sure if MediaTek drivers look at the "original fps", if so, its IMO wrong.

MTK should not look at any fps, because kodi stears the timing.
Maybe worth a try providing this clip to MTK

MediaTek should know nothing about container fps. Video decoder only receives ES, no?

And how does SPMC17 fix it? Think we haven't really understood the real problem.

Could I see the spmc v17 log that was working correctly again? Pastebin is not existing anymore.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Nice - Nicely linear PTS fetched and output. Cool.
