Some TS files played via DLNA cause TV to hang. Please help

[mike tv]

Hi I've come across a very strange playback issue via DLNA. I am trying to play standard definition MPEG2 TS [DVB-S] from a Humax Foxsat PVR [running MediaTomb] over Ethernet/cat 5 cable on my Philips 32 PFL7606 [Firmware 0.14.93.0]

I noticed it can play a lot of TS files from the Foxsat but not all. When I looked into it there was a pattern. I discovered that its is not able to play the recorded .TS files form certain specific channels. What is really strange is there is a channel: Film 4 and it has a +1 hour version Film 4+1. Its the same programming shown one hour later, but the recorded TS files from Film4+1 don't play where as the TS from Film4 do play!

I did a review of the channels I am interested on the Foxsat and out of the 54 channels I tested the 32PFL7606 couldn't play the TS files from 12 of them.

When the TV tries to play a TS file from one of the *wrong* channels it causes the TV to sort of hang. And sometimes 4 little dots appear and nothing happens the screen stays blank.

I tried my best to analyze the *bad* TS files. I looked at MediaInfo results for the files, FFMEG results, ProjectX log files, VLC log files but I'm just not knowledgeable enough to spot anything wrong in the files.

I also had the same issue streaming copies of the same files from my Mac to the TV using Serviio DLNA software. TS files from *good* channels would play but the TS files from the *bad* channels wouldn't. So its not an issue related to the Foxsat PVR.

• Does any one have the skill or software to analyze a 30 second sample of a *good* [Film4] TS and a *bad* TS[Film4+1] and see if they can figure out whats causeing the TV to hang? I can upload the samples if any one could help.
• Also Is there any way that the TV could output a log file that I could take a look at?

Any help appreciated. Thanks.

Did you check the differences in GOP length?
There are maximum GOP-sizes specified for DVD-compliant MPEG2-Streams: 15 frames NTSC, 12 frames PAL: http://documentation.apple.com/...
DVB-MPEG2-Streams, which are broadcasted over DVB-S, contain larger GOPs. Some MPEG-Decoders cannot process these streams properly.

Could you upload the ProjectX-logs?

Hi Möp, thanks for the reply.
I'm not quite sure how to check the GOP length. Looking at their MediaInfo details their "Format settings, GOP" seem to be the same.

Its worth noting that the TV plays quite a lot of the DVB-S TS files no problem.

Thank for that link I'll read up on it.

Could you upload the ProjectX-logs?

These are the "normal" log files. I can also get ProjectX to out put a "big" log file. I've also posted the MediaInfo details too.

Thank you for the log files.
You find the GOP-lenghts in the "++> Mpg Video:"-section in the log of ProjectX.

It seems that we don't have a GOP-Problem here. It must be something else.
Film 4 TS which plays fine:

-> GOP summary: min. 18, max. 36 fields; contains interlaced frames

Film 4+1 which doesn't play:

-> GOP summary: min. 12, max. 24 fields; contains interlaced frames

Thats means the MPEG2-Decoder can handle large GOPs.

Let's check:
[x] You already have the latest ProjectX-Release.
[x] Format, resolution, aspect ratio: identical
[x] Bit rate: 4 361 Kbps plays fine, 3 058 Kbps not.

I'm sorry I think I can't help you. I'm not an expect, just had the GOP-Problem with different DVD-Players.
[ ] What about USB-Playback? Is it the same behaviour compared to DLNA?

I'm sorry I think I can't help you. I'm not an expert..

No need to apologize. That link you posted previously and the info on GOP has been educational for me.

.
[ ] What about USB-Playback? Is it the same behaviour compared to DLNA?

I'm going to do some test on that and I'll post back with my results.

Thanks again

I'm after discovering that if I let the TV try and play some of problem .TS files [via DLNA] for long enough it will eventually play them !

If I press play, then the TV screen goes black and if I leave it for around 2 mins the file plays perfectly. However there are some that don't play. I left them for around 5-6 mins and the TV eventually just moves on to the next file in the folder.

Hi,
i am just reading in thi sforum and found this topic.
I have nearly the same problem :
Streaming is done by mediatomb installed on a dreambox DM800SE HD. (internal HDD)
Streaming of open HD movies (ARD/ZDF/ARTE...) is ok, i can watch them on the TV
Streaming of HD+ movies (RTL/SAT/Kabel...) is not ok, the TV tries to open the file, but display stays black.
The funny thing is, when i cut the ads with DVR-Studio and save the .ts file back to HDD in Dreambox, then i can watch this movie on my TV via streaming.
BTW. Both, Dreambox and TV, have a valid HD+ Smartcard and both have the latest software.
What happens, has anyone a good idea?
Regards
Reinhard

the TV tries to open the file, but display stays black.

When the screen goes black have you tried simply leaving it alone and waiting? I was surprised to find if I waited for 2 or 3 minutes or more some problem files actually did eventually played. Its not ideal but its better than nothing.

There is another issue with your situation, the TV isn't actually DLNA certified to play streamed HD content. The DLNA cert only has it covered for SD: MPEG_TS_SD_EU
Having said that, I have been able to play some HD .ts files via DLNA. I haven't tested it too much though as I don't have a lot of HD content to test with.
