Transcoding issue with WTV files

[atc98092]

Using the standard Samsung H series profile on my JU set. I previously had WTV transcoding working, but after a clean install it now gives a playback error. Here is the FFMPEG command line Serviio is sending:

  Code:

2015-11-10 16:16:10,298 DEBUG [ProcessExecutor] Starting C:\Program Files\Serviio\bin\\..\lib\ffmpeg.exe -fflags +genpts -threads auto -i D:\Movies\Werewolf in a Girl's Dormitory (1961).wtv -y -threads auto -c:v copy -c:a copy -map 0:0 -map 0:1 -sn -f mpegts C:\Windows\TEMP\Serviio\transcoding-temp-123-sam_h-ORIGINAL.stf


And of course, if I rename the file with an MPG extension I can play the file on both the TV and computer. Any ideas why it's not working? Attached is a portion of the log, in case there's something besides the command line that is throwing it off.

Here's the media info for one file, but none will play:

  Code:

My gut feeling is that something has changed between the H series and J series. No idea what.

OK, here's another one. Here's the FFMPEG command:

  Code:

ffmpeg.exe -fflags +genpts -threads auto -i D:\Movies\Alias Jesse James (1959).wtv -y -threads auto -c:v copy -c:a copy -map 0:0 -map 0:1 -sn -f mpegts C:\Windows\TEMP\Serviio\transcoding-temp-10-sam_h-ORIGINAL.stf

When Serviio runs the command, it must be failing. I can run the command myself, and the entire file is transcoded in less than 30 seconds. If I change the file extension to MPG, I can play the video on my computer as well as on the TV with Serviio.

The only difference between my manual execution of the command and Serviio's is that I enclose the file name in quotes because of the spaces in the name. However, Serviio can transcode the file just fine to other players, such as my Roku or Visio E Series TV. Why is it only failing on the Samsung? I also have other files with spaces in their name that are not WTV files, and Serviio can transcode them for the Samsung just fine.

In the past, I had WTV files working just fine, but I forgot to save the profiles file with the changes I made, and now have no idea what I did. This should be working, and I'm completely puzzled by this. I had to remove some of the early lines in the log, as it just barely exceeded the 500k size limit.

As a reminder, this is my Samsung JU7100 using the Samsung H series profile.

Try to change

  Code:

<AllowChunkedTransfer>false</AllowChunkedTransfer>

to

  Code:

<AllowChunkedTransfer>true</AllowChunkedTransfer>

in the sam_h profile (or if you have a custom j profile)

Zip, tried it on my test server, no luck. I'll try the main server tonight, since they're on different versions of Serviio.

When you suggested that, I seem to remember you had me change that before, but can't remember the reason. Maybe this was the reason!

[atc98092]

Tried my main server, same result. File error when playback is attempted.

Seems your first post shows both the mpg and the stf always failing on playback thru Serviio. "[WebServer] I/O error: Connection reset by peer: socket write error"
This contradicts your statement " If I change the file extension to MPG, I can play the video on my computer as well as on the TV with Serviio.
Your second post only shows the stf failing. The mpg was not tried.

So it seems the ffmpeg command did not fail and the transcoded file renamed to mpg plays on your computer but fails on your TV when sent by Serviio.

I would suggest posting the ffmpeg output for the .mpg file which works on your computer, and also try playing it directly on the TV via USB.

You also have not indicated if this problem exists with all wtv's or just these 2, nor have you posted any info on the audio which may also be the cause of the failure.

In my mind the Samsung TVs have not been designed to play transcoded files (ie files with unknown file size) because their own AllShare server doesn't transcode.

So it's quire possible that at some point it'll stop working, especially if the J series changed operating system (now on Tizen, AFAIK). It's hard for me to fix if I don't have one here to play with.

That does not explain why the transcoded file renamed to .mpg does not play via Serviio on the TV. It looks like it also fails with [WebServer] I/O error: Connection reset by peer: socket write error

The renamed stf file (to .mpg) will play on the TV via Serviio. I didn't include a log that shows that. It's only while trying to transcode that it fails. It was working before, but my own fault for not saving a copy of the Profile file before I updated Serviio.

I can't connect to my MediaBrowser from work (they seem to be blocking my DDNS URL at the proxy), so I'm opening it on my iPad over 4G to see if it plays there. Can't seem to get a WTV file to play there either. I'll have to try from a home computer to ensure it's not an iOS issue. I can't seem to get anything to play right now with Media Browser on the iPad.

Yes, starting with the 2015 Samsung sets, they are all using Tizen now. Like I mentioned, it was working before on this set. And other transcoded files will play, although I'd have to search to see what others require transcoding. Just wish I could remember what it was. I could have sworn it was the Chunked command!

I had a J TV for a week and only managed to get subtitles working. Transcoding is currently no-go. First they didn't properly implement time-based DLNA seeking (included a hack for it), but even then they make weird requests to the server and eventually give up failing the file. So it looks like the TVs can't cope with transcoded files.

Unless someone can find a working server to give me some guidance what the TV expects.

Dang. I had it working before I updated to 1.5.2, but I can't remember what it was that fixed it. I really thought it was the chunked transfer. I'll try some more on my test server.
