Transcoding Files

Hello, I have one question about transcoding.
I have a LG TV and use the lg tv profile. When I want to play a mkv file it says me thatthe file is an invalid format. But the transcoding file went bigger and bigger, but playback stops. Why went the file bigger?

The ffmpeg process (that does the transcoding) will continue even after it has failed on your TV. The file will get bigger until it is fully transcoded. It will be deleted eventually.

Post details of the file that doesn't play and we may be able to help you with that. See here for how to provide this info - MediaInfo will provide the better information.

Ah ok, thanks for info. I was only wondering that after failing the file is getting bigger.
Here is the file, that won't play..
Other files with dts would play with transcoding.

What about the file?

Sorry, I lost track of this thread.

Have you edited your profile (the standard LG profile in 1.2.1 doesn't do any transcoding, but your OP suggests that the mkv file was being transcoded)? Anyway, assuming its the standard profile....

Some LG TV's do not support DTS audio. The standard LG profile in Serviio has some code commented out that transcodes DTS. Try my post: viewtopic.php?f=5&t=10355&p=68933#p68933 and see if this rectifies the problem for this file. If that doesn't work then post the details of the file using MediaInfo (see viewtopic.php?f=5&t=4510).

Yeah I commendet that out, that dts is transcoding. Other files play normally, but they are a little smaller! Maybe this is the problem!
I provide Media Info File later.

Sorry for the long delay, but here is the mediainfo:

As a test, you can try reducing the video bitrate for the file - change your present LG profile to (lines 2 to 4 are new, the rest should already be there):

  Code:

<Transcoding>
   <Video targetContainer="mpegts" targetVCodec="mpeg2video" maxVBitrate="12000" targetACodec="ac3" aBitrate="384">
      <Matches container="matroska" vCodec="h264" profile="high" levelGreaterThan="4.0" />
   </Video>
   <Video targetContainer="mpegts" targetACodec="ac3" aBitrate="384">
      <Matches container="matroska" aCodec="dca" />
   </Video>
   <Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" aBitrate="384" >
      <Matches container="flv" />
      <Matches container="asf" vCodec="wmv2"/>
      <Matches container="rm" />
   </Video>
</Transcoding>

If it works then try varying the maxVBitrate to "15000" and then "17000" to find how high we can go before failing. The problem with this is it will transcode files that may not need to be, but lets work out what's happening first.

No it says again, invalid file. And with this Profile, encoding is very slow!! So other video files won't work or are very very slow.

[DenyAll]

That's fine. This was only designed to test whether bit rate was the issue - it may pay to do one more test with a low bit rate, say 4000 to rule it out all together.
If you remove lines 2-4 in the above do you end up back with the profile you started with? If not can you please post your profile just so we are on the same page.
How many files are failing?

Here is my current profile. It workes fine (til now) with all video files except the one above from me.

  Code:

<Profile id="8" name="LG TV / player" extendsProfileId="1">

Given that it is only one file, and that I can't see anything obvious from MediaInfo for the file, it could simply be that this file is malformed in some way. It may be simpler to re-mux this file - try, from the command prompt:

"path\ffmpeg.exe" -i "\\10.0.0.1\video\movies\8 Mile (2002)\8 Mile_(2002)_1080p.mkv" -map 0 -vcodec copy -acodec copy test.mkv

substituting path to where your copy of the ffmpeg command is (in Windows 7 this is C:\Program Files\Serviio\lib\). This will simply re-mux the video and audio to a new mkv container (test.mkv). See if that plays or has the same error.

Failing this you may want to look at MakeMKV to recreate the mkv file.

thx for the tip, but with this command I get something like this:

  Code:

[matroska @ 0xfa85c0] st:0 PTS: 6626325 DTS: 6626325 < 6626353 invalid, clipping
[matroska @ 0xfa85c0] st:0 PTS: 6626335 DTS: 6626335 < 6626353 invalid, clipping
[matroska @ 0xfa85c0] st:0 PTS: 6626345 DTS: 6626345 < 6626353 invalid, clipping
frame=158908 fps=165 q=-1.0 Lsize=15093964kB time=01:50:27.71 bitrate=18656.5kbits/s

And I think this "invalid" is something bad.

I cannot create a new mkv file wih MakeMKV.. It said, that he had failed.

Can you actually watch this movie direct eg. On your PC.

Yes on my notebook with VLC it works. Because of that I'm asking why only that video isn't working

[DenyAll]

You should be able to re-package the file using MakeMKV. As you can't, and because of the errors you have when ffmpeg'ing it, it looks like this file is stuffed in some way. Have you played it all the way through in VLC (looks like the error could be late in the movie)?

In any case, it seems to be a one off, so you wouldn't change the Serviio profile to cater for it (even if you could work it out, you'd likely make all other mkv's unplayable). I'd try to get the file from its source again.

MakeMKV starts to convert, and in middle of the process it fails!! At start it says, track 4-6 were skipped because of an error or because of the type.
And I think I remember, that I played the file over Seagate GoFlex TV.
I played it everytime with VLC.

Don't worry about the one file. Something is wrong. I can download it again xD

Thanks for the help
