Connection drop while playing online video with Samsung c630

Hi,
First of all I would like to say thanks for developing very good DLNA media server. Especially recently added "online content streaming" is very promising.

Unfortunately I am having problem with streaming any online feeds. My TV stops playing with “Network Disconnected” error. I am having zero problems with my local files playback. Can someone help me with this?

P.S.
I have looked into Serviio temp directory and it contains transcoding-temp-*-MPEG2TS.stf file with video of online feed that I am trying to play. When I am moving that file into Library folder and changing extension to .mp4 file it can be played with no problems. Also I have noticed that connection drops for different files at different time. Short files can’t be played at all. It seems that there is some buffers synchronization issue. When I am changing profile to transcode online recourses by using forceVTranscoding="true" *.stf file size in temp directory is increased and feed plays longer.

Hi,

I have the exact same type of problem as you and use Samsung UE46C6005. Long online videos usually works until the last couple of minutes before I get network error. Very shot ones 10-15sec does not start at all. I have not mange to play any online content until the video ends.

I have done some testing.
Changing Profile to Samsung B series and generic profile does not help. (I read on the forum that B-series profile always transcode online content.)
Watching from XBMC works so I guess this is related to Samsung.

sounds to me as if you hitting the files size limit, and that why it stops. Try lowering the quality of the online content from high to medium. ( in serviio console )

I have tried all:low/medium/high noting helps.
P.S it is looks like in high plays longer.
Low plays longer too. Because of transcoding involved?

there is no transcoding in the C/D series profiles.

I have added flowing on
<OnlineTranscoding>
<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" aBitrate="384">
<Matches container="mp4"/>
<Matches container="flv" />
</Video>
<Audio targetContainer="lpcm">
<Matches container="flv"/>
</Audio>
</OnlineTranscoding>

and as well as I know for example youtube for low bit-rates video streams flv files.

BTW I was not able to play online video till end using low/medium/high and even before I have changed profile.

wow that sucks, im running mine with no transcoding and it play everything i through at it, (40c750 LCD TV) wonder why the C630 are so bad, very strange.

Same result for me. Changing quality does not help.
Serberus: Does online video work on your Samsung LE40C750? It would be interesting if this is a general Samsung problem or related only to the C and 6 series..

Any other tests or recommendation to narrow down the problem?

yes it works perfectly with NO transcoding, im one that beta tested the C series for serviio 0.6

If I am not mistaken, there are two types of 6 series TV with internet@tv and without it. They have different firmware and hardware. C630 is most like to 5 series TV. It is interesting to know how Serviio works with 5 series TV. By the way I believe that this issue can be solved in Serviio. I have iMediaShare android app and with it I have no problem to stream YouTube videos.

There could also be 2 types of mainboards on the same model with different firmwares. T-VAL6DEUC and T-MSX6DEUC. I have T-MSX6DEUC on my Samsung C6005.
Which one do you have on your C630? I have also tested out with iMediaShare and it works OK.

I have T-MSX6DEUC too.

ok this make no sense to me as i should work fine, ok let go back to basic's can you guy provide me withh ffmpeg -i result for a working online feed and one that fails please, so i can try and work out whats going on, also to keep it simple and rule out plugin problem can you do it with youtube feeds as tehy dont use a plugin.

OK. First of all to keep it simple I have reverted changes on profiles and restarted server to apply changes. Unfortunately I did not know any online feed that can be played till end. Almost all of them can be started but disconnects about 40 second till end. Feeds that shorter then ~40 second event can’t be started. If I am not mistake YouTube requires plugin. BTW here is YouTube result for “charlie bit my finger” video that even can’t be started. Probably this one http://www.youtube.com/watch?v=_OBlgSz8sSM
In *-cmd.txt I have attached command line that ffmpeg starts by server when I am trying to play video on TV
In *-out.log I have attached ffmpeg –I “url” stdout. Is it what you asking for?
If you need .stf files. There are big I can’t attach.

Please let me now if you need anything else.
Thanks for trying to help.

P.S I have hit the limit. Let me know if you need TED-out.log as well.

ok so they are FLV files

try this online transcoding section and see if that solves the issue

  Code:

<OnlineTranscoding>
   <Video targetContainer="mpegts" targetACodec="ac3">
      <Matches container="mp4" aCodec="lpcm" />
      <Matches container="flv" vCodec="h264" />
   </Video>
</OnlineTranscoding>

      <Matches container="flv" vCodec="h264" />
   </Video>
</OnlineTranscoding>

Following is my version that i have reverted to simplify as you suggested.

<OnlineTranscoding>
<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" aBitrate="384">
<Matches container="mp4"/>
<Matches container="flv" />
</Video>

is there differences that can make work?

[Cerberus]

you cant simplify my code, it need to be added exactly as i wrote it as all you will do with your profile is hammer the pc running serviio with transcode job that are NOT required.

OK. I have tried exactly what you say. Still can’t play till end of video. TED video can’t be played at all.
Please let me know if you want to try something else.

BTW: I don’t think that it is something related to transcending. Please see why.
Suppose we have online video “some video”. Let’s say it has ~180 second length and factory default profile for c series Samsung TV.
1. Start play “some video” video.
a. Server starts ffmepg. ffmpeg.exe -i " video url" “something else” D:\tmp\Serviio\transcoding-temp-1000000000160006-MPEG2TS.stf
b. TV stars showing video and disconnects at ~140 second.
2. Start play “some video” video again.
a. Server dose not start ffmepg since it already has generated transcoding-temp-1000000000160006-MPEG2TS.stf file
b. TV stars showing video and disconnects at ~140 second. Same as before.
3. Move transcoding-temp-1000000000160006-MPEG2TS.stf D:\video\transcoding-temp-1000000000160006-MPEG2TS.mp4
4. Force refresh and start play transcoding-temp-1000000000160006-MPEG2TS.mp4
a. TV plays till end with no problem.

So maybe I am not correct but I can assume that TV has no problem with video format. Only problem is streaming .stf file.

Can I affect on ~140 second playing time. Make it play longer or shorter. Yes.
To make it play longer
<OnlineTranscoding>
<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" aBitrate="384" forceVTranscoding="true">
<Matches container="mp4"/>
<Matches container="flv" />
</Video>
</OnlineTranscoding>

Please notice that I am using forceVTranscoding="true".
Now video plays till ~160 second
To make it shorter use this one
<OnlineTranscoding>
<Video targetContainer="mpegts" targetVCodec="mpeg2video" maxVBitrate="512" targetACodec="ac3" aBitrate="384" forceVTranscoding="true">
<Matches container="mp4"/>
<Matches container="flv" />
</Video>
</OnlineTranscoding>

Please notice that I am using maxVBitrate="512".
Now video plays till ~130-135 second
What is a different? I don’t know. Maybe generated *MPEG2TS.stf file size?

OK. I have tried exactly what you say. Still can’t play till end of video. TED video can’t be played at all.
Please let me know if you want to try something else.

i wont even discussed TED as there system is pure crap and id have to use so much transcoding to make it work it would make every other feed look crap too.

as for the not play to the end something has to be basicly wrong with the setup cause this simplely isnt possible as i have it working myself.

[moltra]

Try this after you try to play a file and it disconnects copy the file generated by ffmpeg to your serviio video directory and see if it will play fully.

This will help make sure there is not an error with the transcoding.

Also you did not specify your network setup, but if it is wireless please run the tool from this thread to rule out any other network interferences.
