25fps mkv judder on pana p50vt60

[Ladislav]

I'll redo this evening.
I have suspect that tv does not detect well pal/NTSC.
I have one other mkv , almost 22gb, and that one goes well, so there is no net problem,
Maybe il do both mkv play for to make compare.

[ExSport]

It depends on if file is streamed, remuxed or transcoded. So if your 22GB MKV is remuxed, bitrate can be about 15Mbit but in case of transcoding it can be easily 200Mbit
Btw. what is your connection? LAN 100Mbit, 1Gbit, WIFI, PowerCord,...?

[Ladislav]

I'm on 1gb LAN
But have no Ida if tv goes 1gb
It should be 100mb min

[Ladislav]

I made ne trace
I played also 2 different mkv for compareits all attached

[ExSport]

You are using forced streaming for mkv:

Code: Select all

Reading disable_transcode_for_extensions: default: "", current: "mkv,avi,divx,mp4,jpg,mov"

This is not good technique how to say UMS that MKV is supported. This setting makes that UMS loose the total control about this file so it is streamed as is without any internal control of file (audio/sub preference, incompatible audio/video codec or encoder settings, wrapping DTS etc.)
The best way is to configure supported= line for this purpose (in past it was like described above but not sure with newer UMS versions if they aren't more aware of this configuration --> but configuring supported= line is better in all cases )
In log I can see something is wrong. It can be your file or your ffmpeg version.
Log is full of nonstandard messages in very high number (about 700?)

Code: Select all

matroska,webm @ 0xb407f80] Unknown entry 0xF0

And this spam is only for generating two thumbnails.
Still your file is streamed as is, without usage of any video engine so it should not be root cause of stuttering (except the situation file is badly encoded).
Another problem is parsing the file:

Code: Select all

TRACE 2013-12-06 22:24:36.124 [New I/O worker #16] Could not parse bitrate from: unknown
TRACE 2013-12-06 22:24:36.124 [New I/O worker #16] The full error was: java.lang.NumberFormatException: For input string: "unknown"

But later in log it seems MediaInfo parsed correct bitrate...
What exactly is your problem? In log it seems like you are trying to rewind after a while or it does TV itself? Log shows starting the stream then immediately sending the end of file, later it starts again from almost the start, after few secs it asks for chunk far inside the video, few seconds after it asks for another chunk inside file minutes farther...weird if you didn't use FF/RW.
Do you have another file, more general for new test and also trying some encoder engine inside TRANSCODE folder? [MEncoder] one and [tsMuxeR] one?

[Ladislav]

Thx for your response.

First play log should be done by TV itself trying to show preview. (which i disabled)
Then I started film and did some fast play then I let it go for few seconds.
So it seems that UMS. don't recognize well MKV, Cause I set it like direct stream.
Is there any way how I can setup correct config for all supported formats for my TV.
doing naturally stream all time when TV know handle that format?.
My NAS have almost no computational power, so its hard to let it trans-code.
I have HP microserver so direct stream is preferred.

Thx again for your time.
P.S: I was following thread about Panasonic.conf, but its probably not my case cause VT60 is a bit new model
and many things it can handle itself.

[ExSport]

Then I understand why the log is so hard to read and finding correct part which is play time and not FF/RW or preview generation
To support MKV natively it is better to remove mkv extension from "StreamExtensions=" line and create new one as "Supported=" (MediaInfo=true must be used)

Code: Select all

Supported = f:mkv     m:video/x-matroska

Try using this one. It defines that all MKV files will be streamed as is, with MIME type "x-matroska"

Code: Select all

Supported = f:mkv      v:h264    a:aac|ac3    m:video/x-matroska

This one say the same as above but that only h264 video and aac+ac3 audio is supported only (so the rest will be transcoded, e.g. MKV with DivX video and DTS audio,...)

[Ladislav]

Now i list all my supprted formats and ill try make my personál conf, have to study it a bit.
Thx for info.
Ill keep you inforomed about my progress.

[Ladislav]

I install UMS 3.3.0 and i added just line for suported mkv video, I removed all transcode exceptions
but stil no way

UMS does not send to TV that played video is in EU 25fps so TV think that is 30fps based source and its judding


There is no transcode its just straming it.

But is strange cause TV can handle 24p all NTSC and PAL frame rates, from HDMI but from dlna no
any other ideas?

Thx.

[Ladislav]

one other strange thing. evidently I miss somthing ...
this is trace log: where is video mkv (ac1) with support line set, but not recognised
then in sequence there is exception about missing encoder
