Frame Rate change on LiveTV cause's stuttering playback

[JeremyFr79 228]

Ok so I've noticed an issue with transcoding liveTV playpack.  What I've noticed (and seen in the logs) is for instance you're watching a 1080i channel.  The channel itself is broadcasting at 1920x1080 60 interlaced frames (or 30FPS)  However said channel could be airing a movie which of course is shot at 24FPS.  What I'm seeing in the logs is that ffmpeg see's the channels native resolution/framerate however it's transcoding at the framerate of the material being played on the channel.  So for instance again I'm watching a channel that's broadcast in 1080i, but they're playing a movie, ffmpeg does the transcode at 25fps (which isn't even right as it should be 23.97 or 24) during playback of the movie and playback stops/stutters etc.

 

Now what's even more interesting is that a commercial will come on that's at the 30FPS of the channel and playback is smooth and perfect.  I've noticed in the transcode logs you can actually watch ffmpeg change on the fly as say a commercial come's on etc.  Is there any way to have ffmpeg lock to the native resolution/frame rate of the channel and avoid these transcode anomaly's that effect playback?

we preserve the input framerate unless the client device indicates it has a limit or requirement

Here's a recent log, if you notice the framerate never get's higher than 22 - 23fps,

I don't know that it's anything Emby is doing, as much as ffmpeg.  In reality I think ffmpeg is picking up on 2:3 pulldown and adjusting accordingly however this is breaking playback.

I can stream a different channel with the same properties to the same device and it plays fine with correct FPS etc.  But the minute the source material on a channel changes to something not channel native ffmpeg takes a big massive shit it seems.  Usually I notice this when commercials air vs. the other way around.
