cannot navigate in an mkv file - sumeet - 2016-05-25

hi
i am using open elec 6.0.3 kodi 15.2 isengard on raspberry pi b+
The video file in consideration has following codecs

Quote:Input #0, matroska,webm, from 'f:\epl.mkv':

I cannot fast forward to any minute in it . If I leave it running then playback is smooth till the end but if I try to move to any point in video the frame freezes while time slider keeps ticking .

How can I debug this issue ?

How can I debug this issue? Jesus does no one read before they post?

Got it nickr .
I will come back with logs .
BTW , my raspberry pi b+ has no internet access .
I can copy log file to usb stick and post.
I am reading http://kodi.wiki/view/Log_file/Advanced .
Can you tell me what component specific logging should I enable ?

Thanks.

RE: cannot navigate in an mkv file - McButton - 2016-05-30

It's an MKV error. Your container headers are damaged.
https://mkvtoolnix.download/
This will allow you to open the MKV, add or remove files...if you want... and really just re-mux it. That'll fix your issue. It's not Kodi.

RE: cannot navigate in an mkv file - sumeet - 2016-06-30

been a long time .
sorry .
log file at http://pastebin.com/DkArzNpJ for mkv file.
let me know if you can find the cause of error while navigating .
By the way , the file in question plays properly in vlc media player .
So I think the issue is with kodi OS .

Thanks.

I will make log for mp4 soon and also let you know if remuxing mkv helped.

RE: cannot navigate in an mkv file - PatK - 2016-06-30

VLC is somewhat more tolerant of errors, try another MKV or follow McButton's advice.

@sumeet that is a very old build:

Code:
00:00:40  40.550571 T:3040436224  NOTICE: Raspberry PI firmware version: Aug 12 2014 18:25:27

OpenELEC has been slow to update lately. I'd suggest trying with LibreELEC (Jarvis 16.1) v7.0.2

RE: cannot navigate in an mkv file - sumeet - 2016-07-01

ok popcornmix .

Meanwhile , here (http://pastebin.com/nvFJKYMs) is the log for mp4 file in which i cannot navigate in time scale . if I start it from beginning , it will play until the end smoothly but when I try to move forward or backward , the screen freezes .

Also , i will report about mkv issue as soon as remuxing using mkvtoolnix gets done .

Thanks.

RE: cannot navigate in an mkv file - sumeet - 2016-07-02

i have raspberry pi b+ model .
I am using berryboot to run multiple OS from single SD card .
got LibreELEC_7.0.1.img128 from https://sourceforge.net/projects/berryboot/files/os_images/ .
Unfortunately - got an empty screen (monitor appears full black) on using that image . audio works . pressed s and enter to shut down the seemingly headless OS .
Will get another sd card and install libre elec on it .

Meanwhile ,
McButton - I did following for mkv .
Used http://shana.pe.kr/shanaencoder_download in windows and did stream copy to mkv . the output file is almost same size as original mkv .
Will see if it is navigable ?
Please let me know if I am erring somewhere .

Thanks.

RE: cannot navigate in an mkv file - nickr - 2016-07-03

Why not use mkvtoolnix instead of something obscure from korea?

RE: cannot navigate in an mkv file - Ned Scott - 2016-07-03

ShanaEncoder is re-encoding the file, which shouldn't be necessary. Re-encoding will also reduce the video quality a little bit. mkvtoolnix should fix your issue without needing to re-encode.

RE: cannot navigate in an mkv file - sumeet - 2016-07-05

ok guys , i used mkvtoolnix on files (an mp4 and an mkv whose ffmpeg analysis is in older posts of this thread) under consideration .
The output by mkvtoolnix was mkv in each case . I just added file as input and clicked start muxing .
For convenience , i prefixed mkvtoolnix to output file names .
Then played these output files alongwith other mkv and mp4 that play well .
Here is the log -> http://pastebin.com/S526GqaV and http://pastebin.com/i9r3xkSf
In the log you can notice that files - /var/media/FreeAgent GoFlex Dri/video/movie/hollywood/How to Train Your Dragon 2 (2014) [1080p]/How.to.Train.Your.Dragon.2.2014.1080p.BluRay.x264.YIFY.mp4 and /var/media/FreeAgent GoFlex Dri/video/movie/hollywood/dukes-of-hazzard-2005/duke-of-hazard.mkv - played smoothly even when I jump to different times or fast forward them.
While in mkvtoolnix files (/var/media/FreeAgent GoFlex Dri/video/movie/hindi/mkvtoolnix-Ek Paheli Leela.mkv var/media/FreeAgent GoFlex Dri/video/movie/hollywood/dirty-harry-un-navigable/mkvtoolnix-dh.mkv) , the picture gets frozen when I try to jump to different time . media player shows status as playing but the timer does not increment . When I fast forward these files then screen is frozen but timer leaps by seconds as normal .

Please let me know , what you infer .
Thanks.
