H264 Hi10p / 10-bit transcoding

Hey there! I did a search already and didn't find anything on this topic yet. Does Serviio support transcoding of H264 Hi10p files? I run XBMC on an ION box and with the current VDPAU profile Hi10p is not supported (which means that 1080p or 720p files in Hi10p stutter badly). I was hoping to use the power of my core i5 desktop to transcode these types of files to XBMC but I need to know if Serviio supports this. Thanks!

If there is no mention on the forum, then its probably that no one has had a problem/doesn't use them. If I was you I would simply try it, install serviio add the files and try to play them. Serviio will support transcoding from pretty much anything provided ffmpeg can read it.
If they don't work (it is quite likely that serviio won't try to transcode them) then http://wiki.serviio.org/doku.php?id=file_np and we can setup a working profile for them. You could also try the Direct TV profile that transcodes almost everything, although it is always nicer to transcode only the videos that really need it.

Edit, looking at a profile we can select to transcode based on the profile and level, so far I've only seen profile main and high, so would need zip to confirm if we could use 'high 10' in the profile field.

  Code:

<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" aBitrate="192">
   <Matches container="matroska" vCodec="h264" profile="high" levelGreaterThan="4.1" />
</Video>


OK I have installed serviio and the problem that I see streaming from XBMC remains. Namely I am getting like 8FPS on a file which has 24FPS :-/

My desktop is a core i5-2400, 16GB ram, windows 7 64-bit, dual ATI radeon HD 5670 (crossfired).

I would really like to be able to transcode these 1080p and 720p H264 Hi10p files by taking advantage of the computing power of the machine upon which they reside, rather than asking my little Atom N330/ION box to do it...

Can you try the DirecTV HD-DVR profile (select it in the console).

  Code:

Format profile                           : High 10@L5.1

was what I was expecting, If we can select the High 10 in the profile then we can only transcode what is needed. Otherwise, we might be able to get away with just using the level to filter out those files. Failing that, we can certainly get it to transcode all h264 content.

I'd be thrilled with only transcoding the hi10p stuff.

Can you try the DirecTV HD-DVR profile (select it in the console).

Where is that setting?

EDIT: never mind - I found it. Yeah that totally worked. 1080p 10bit file playing cleanly and perfectly, with one exception. Subtitles not working LOL

reading up a little in the forums, it looks like I have to make a tradeoff - either MKV gets transcoded OR MKV doesn't get transcoded but embedded subtitles work.

Is there no way to transcode MKV but retain the embedded subs?

[zip]

not at the moment.

Oh poo. is that something that I could contribute to?

Waiting for ffmpeg https://bitbucket.org/xnejp03/serviio/i ... -subtitles

ticket opened over a year ago. Responsible: nobody. Version: None. Priority: Major...

any ETA on that?

[will]

Sadly we are waiting on ffmpeg supporting this feature, once it does it will hopefully be intergrated into serviio pretty quickly.

I would love this as my player doesn't allow fastforwarding if I don't enable transcoding, but then I loose subtitles, i've had a look a few times for an intermediate solution, but I don't think there is one.

It's shockingly hard to find exactly what google search on FFMPEG will describe exactly this use case. I'm trying to determine if there's already a ticket on FFMPEG's trac for this problem. Any ideas?

[will]

So i've looked for ffmpeg burn in sub or ffmpeg hard code subtitles etc for embeding the subtitles into the video as text.

FFmpeg devs discuss it for example here: https://lists.ffmpeg.org/pipermail/ffmp ... 17059.html
I'm following their mailing list so should know once this becomes available
