Serviio

Hi,

I noticed a line in C/D series profile which instructs serviio to transcode mpegts file with mp2 audio to ac3 audio:



However I have this rather big file:



and problem was that when transcoding this 32GB file my system couldn't keep up and concert was impossible to watch (a lot of bufferings, huge disk I/O operations).
However when I commented-out transcoding of mp2 audio the file played (and plays) with no transcoding/buffering and with perfect audio on my Samsung C6500 series TV.

Maybe this transcoding is only for D series TVs? As I encountered C series can play mp2 audio stream with no transcoding.

Interesting because according to my D series manual, only mpeg-ps will play mpeg and lpcm audio. mpeg-ts shows as only playing mp3.

Also seems strange that you can play a 50000kbps file over the network with no buffering. I've never achieved such bitrates.

You can of course use the maxVBitrate parameter to limit the transcoded bit rate. I limit mine to 30000.

another reason why we need to split the C and D series profiles.

I don't see that. I suspect this is a manual error for the D series. Doesn't make much sense that ts will not play mp2 when ps will. What other differences have you documented that require a split?

Well I wonder why this line was added in the first place. Actually it should say:



because m2ts files with pcm_bluray audio do not play audio on my TV without transcoding. When I added this line to transcoding profile everything is fine with audio as it is transcoded to ac3. C series manual also does not include mp2 or lpcm audio support for ts streams. It would be interesting to test another file with mp2 audio and ts container. Nevertheless this file also plays nicely directly from USB drive.

I stream through wireless connection using 5ghz band and 300mbps routers. I manage to squeeze a constant 8 MB/s which is in most cases enough for 1080i streams. However I'm still having trouble streaming 1080p content with high bitrate. I suppose I should upgrade to 450mbps to achieve that.

I should also say that I'm using beta 2 of 0.6.1. I did not check the profile of 0.6.0.1 version.

Cant see this supported in my D series LCD. I know there are "D" Tv's in samsungs LED, LCD and plasma models... I assume the hardware platforms would vary between these?

Table is identical to my C series TV. I don't know too much about video and audio compression standards but after some googling I think Samsung's mp3 audio decoder can also decode mp2 audio stream although it is not included in spec table. Actually it might be that TV can decode all three audio layers of mpeg-1 standard (mp1, mp2 and mp3) for ts stream with mpeg-2 video (at least). MP2 audio is ussualy used for broadcasting (and my concert is a hdtv rip) in DVB channels.

As I mentioned I'm not good at this but it can be that Samsung uses the same decoder for video files as it uses for DVB (T or C) television.
Excuse me for my technical ignorance if I'm wrong.

To wrap up I think default profile for Samsung C/D series should be altered and line after:

should be changed from

to

One more thing I noticed is that one mpegts file with lpcm audio was throwing an error and not playing while trying to transcode to ac3.

Problem is that lpcm stream of this file is 96000 Hz. Although aSamplerate default should be 48000 Hz (which I did not alter) ffmpeg.exe received a command to transcode to 96000 Hz ac3 which is out of ac3 "coverage" and therefore transcoding failed with an error and file was not able to play on my TV.

So I forced aSamplerate for ac3 to be 48000Hz in profile. Now my (I hope final) working profile for Samsung C/D series is changed from:

to:

So far this setup works.
I hope anyone else will find this useful.

I have a problem with BIG mkv/flac where it stops and loading every 10:th second. I have changed the profiles file due to that at first I did not get any sound in mkv/flac but it worked fine in mkv/dts. Now it working however loading for 3-4 seconds every 10:th second. I tried to lower audio bit to 128 without any change. It is all showing video withouit transcoding.

you're transcoding h264 to mpeg2video, which might be quite slow for HD videos, depending on the CPU. Any reason why you're not just remuxing h264 to mpegts?

If I don't have targetVCodec="mpeg2video" then I get Adio Codec not supported when I try to play the movie in my Samsung D7000... Any Idea?

Hi, my experience with Samsung C series TV showed that TV is rather slow while decoding ac3 streams in mpegts container (dunno why). Interestingely I even get better results (no bufferings) leaving ac3 audio but remuxing video into mpeg (not mpegts). To avoid bufferings and make these files compatible with TV I have the following config for matroska with flac (and others in that section):



mp3 is not the best format and sometimes may cause an audible degradation in audio quality (not to mention the loss of surround) but it works ok for my not-so-high-end stereo audio system. Another option would be to transcode to aac as it supports surround. It worked for most of my files but not for all so I was forced to choose mp3.

And there is no need to transcode video. Check if that works for you.

When it comes to the Video stream that works great now with that line, however I get a messege on the TV (D7005) saying; Audio Codec not supported...

Video works but no sound...

HI, maybe this would work:



I have one mkv/flac file and it works with mp3 transcoding for me fine on ue32c6500. There maybe something with FLAC stream. Can You post ffmpeg.exe -i of the file?

Noob here. I have a Samsung BD-C6500 Blu-Ray player. I've deduced it can't play (without the audio & video stuttering and breaking up) video files whose overall bitrates ever go over about 8 Mbps. I like to stream DVD .VOB files which sometimes exceed this limit, so I'm looking into my options. With the C/D series profile, Serviio is working OK with this player, but unless I've misconfigured something, it doesn't seem to correct this issue. I'm under the impression I need to edit the transcoding section in profiles.xml, but I don't see a way to toggle transcoding based on bitrate. I also don't want to lose any surround channels. What should I do?

Here's an example of one that breaks up badly. Although overall bitrate is low, according to VLC stats the bitrate goes above the stated 8 Mbps every so often, and the player never recovers. In this case it seems the audio is kind of a hog, but it's fairly representative.


Here's another with the same issue. In this one, the video is pushing the limits, too:


Let me know if you need more info. Thanks, and sorry if this is a FAQ; I tried searching but didn't come up with much other than this thread.

max bitrate is 20mbps, depending your network speed and setup.

It can be related to Your network setup. With mine I am able to watch mpeg-ts of ~48 mbps bitrate with no buffering or stuttering. Mine is TV UE32C6500 and according to manual it should only play up to 30mbps. Also, I get better results transcoding only audio stream for files with lpcm, dts streams (e.g. to ac3 as this will preserve surround if there is any) cause TV is somehow slow on decoding lpcm and dts streams and is buffering rather frequently.

If You cannot play files with over 8mbps bitrate, IMO You should first upgrade (fix) Your network hardware..

Interesting. Maybe we could have a section on the wiki related to certain devices/models with tips like these for ppl who want to tweak their profiles.

hes quoting the comment in teh profile.xml file i think but yer all profiles and information will be added to wiki once i can be bothered to
