Hi, 

 

Is there a list anywhere of what formats the AppleTV version natively supports over having to transcode and any details on transcoding? Like if it's a h.264 in mkv does it just repack as mp4 (assuming mkv isn't supported).  Also any listing on what subs are supported?  I've looked around and haven't seen this info for the AppleTV version.  

 

Thanks

Good question. I'd like to know this also.

Right now it's basically the same as for iOS device. That means most H.264 profiles should play natively. Container is not important (MKV, MP4, MPEG TS, etc - they all will work, Air Video HD will remux them on fly). Subtitles can be embedded (SRT, SSA, TX3G) or external - as long as they are textual they will be shown without transcoding. DVD subtitles (vobsub) currently require transcoding.

That will be transparently transcoded by server. But transcoding xvid/dvix on fly is usually pretty cheap.

I have some m2ts files containing AVCHD at 1080i recorded by a video camera that I'm having trouble with.

 

1) the server analyzer seems to have trouble with a folder with several of these files.  on my apple tv client many of the videos remain blank and never get a thumbnail.  when I try to play ones that do have a thumbnail they often don't play - the screen just stays black with busy symbol.

 

2) when they do play they are being transcoded.  I don't understand why as I turn subtitles (DVD type) off so no need to burn them in, the video is h264, and the audio is stereo ac3.

Are they interlaced? I'm not sure why there are no thumbnails though, do you have those files stored on network drive? How big are they?

yes, as stated above they are 1080i AVCHD from a video cam.  will interlaced video always be transcoded?  if so, what's the purpose of the deinterlace option in video playback in the apple tv interface?

 

they are on an internal drive and vary in size but the largest one is less than 700mB

Sometimes it is not possible to tell upfront if the video is interlaced, so the option forces deinterlacing. However thinking about it, it is possible that the video is interlaced in PAFF  format, which recent iOS devices can't handle so we have to force transcoding. I haven't tried PAFF stream on tvOS without transcoding, will do that later.

I've been messing with codecs on my machine, cleaning things up.  I rely on LAV but was forcing it with my media player.  Directshow merit probably favored ffdshow for some things.

 

If I'm using 32bit server would testing with graphstudionext 32bit accurately show me the graph that the server would use to decode?  Or does it use windows media foundation?

We're using directshow (if VLC is not present), but not rely on on merit. Generally Air Video Server HD will prefer LAVfilters to ffdshow as it tends to perform better.

On my iPad there is a way to list the videos I want to play, for instance for name or date. Is there a way to do that on Apple TV?

When in a folder, slide your figer on the remote pad to the right to get a menu.

Thanks RXDI that works.   In the App on the iPad and also iPhone, there is a setting for date added. So I guess I would like to see that added.  Thanks again for the answer.

You can sort by "Date" added on that same menu when sliding to the right.

I know you can play vob files. I'm not sure about ISO, never tried.
