DVB subtitles makes media player crash
« am: April 16, 2016, 18:52:49 »
Hello,

I have my Emtec media player DVB-T receiver since almost 7 years, and I am using TS-Doctor for the post-processing of recorded .TS files.

Since the 5th of April, DVB-T channels have been totally re-organized in France (all channels are now in HD).
Strange thing: for some channels, when I activate the DVB subtitles (live or on recording made after the 5th of April), my media player crashes.
I don't have the issue with the recordings made before this date.
And I never had this issue in the past with SD or HD channels (also with DVB subtitles).

Factory reset and latest firmware do not solve the problem.

So I was hoping TS-Doctor would detect any anomaly on the stream but this is not the case, and after cleaning my .TS file, media player still crashes when I active the sub-titles.

Do you have any idea ?
Would it be possible I upload this sample so you can check what could be the issue ?

Regards,

Hello,
Thanks for you reply

I just uploaded a 1mn sample name 20160406_0950_fixed.ts (2 audio tracks + 2 subtitles tracks), + the log files.
It reads perfectly with VLC media player, but crashes on my Emtec when I activate either the 1st or 2nd subtitle track.
Also, on my Sony Blu-Ray player (it can read TS), it shows 2 subtitles tracks available but when I activate them, no subtitles are displayed at all (but no crash).

I Hope you'll find what's weird with this stream  ;)
Thanks again

No, subtitles are good. Found no issues. Even TS-Doctor has no problem to decode this subtitles.
1
00:00:00,887 --> 00:00:03,487
Après les amuse-gueule,
on leur annonce

2
00:00:03,487 --> 00:00:05,607
la bonne nouvelle.

3
00:00:05,607 --> 00:00:07,687
On va annoncer à la famille

4
00:00:07,687 --> 00:00:09,567
qu'on va adopter un autre bébé.

5
00:00:09,567 --> 00:00:12,567
Oui. On est d'accord pour la jouer
plus sobre, cette fois-ci.

6
00:00:17,807 --> 00:00:19,207
Explique-moi.

7
00:00:19,207 --> 00:00:20,687
Ca, c'est sobre ?

8
00:00:20,687 --> 00:00:23,487
C'est une banderole
et un peu de musique.

9
00:00:23,487 --> 00:00:24,887
j'ai pas plus sobre.

10
00:00:24,887 --> 00:00:26,647
C'est un heureux événement.

11
00:00:26,647 --> 00:00:28,927
Contente d'avoir un frère, Lily ?

12
00:00:28,927 --> 00:00:31,927
Non, je déteste le bébé.

13
00:00:32,647 --> 00:00:33,927
On a du mal

14
00:00:33,927 --> 00:00:36,887
à faire accepter notre projet
à Lily.

15
00:00:36,887 --> 00:00:38,847
- "je hais le bébé."
- "Pas de bébé."

16
00:00:38,847 --> 00:00:40,487
"je veux qu'il meure."

17
00:00:40,487 --> 00:00:43,487
On devait pas la dire, celle-là.

18
00:00:43,487 --> 00:00:46,487
Le problème est qu'elle n'a pas
l'habitude d'être avec un bébé.

19
00:00:47,047 --> 00:00:49,167
Alors, on a voulu lui montrer

20
00:00:49,167 --> 00:00:52,007
que ce serait super d'en avoir un.

21
00:00:52,007 --> 00:00:54,807
- Il est trop chou.
- Et il ne pleure jamais.

22
00:00:54,807 --> 00:00:57,807
jamais.
C'est même un peu bizarre.

23
00:00:57,927 --> 00:01:00,927
Non. Ma soeur est née
avec toutes ses dents.

24
00:01:01,087 --> 00:01:02,087
- C'est pas vrai.
- Non ?

Regarding Bluray player and subtitles. Different subtitles types exists. DVB subtitles are different from DVD subtitles, Bluray subtitles or teletext subtitles.

Ok really strange they are crashing my media player, while previous ones don't.
Do you think that could be related to the size (in term of storage) of the subtitles bitmaps ?

About my Blu-Ray players, I talked about the media player section of it (my Sony can read .TS files from USB or NAS)

Thanks again

Bluray players using m2ts container format that is very similar to ts (just additional 4 bytes per packet). That the player can read ts just means, it can read the container format but you don't know if it can decode everything that is in the container.

A Bluray player needs the ability to decode DVD and Bluray subtitles because it's used on DVDs and Blurays. DVB subtitles are used only for broadcasting, so the chance is high, that the Sony doesn't support the format or quit on some features.
Maybe your Sony likes SRT subtitles. You could try to decode DVB subtitles to SRT subtitles.
