.ts Issues via USB

[soussef24]

Hi,

According to the product documentation, my 46PFL8606 should be able to play Transport Stream files, however it is having issues to achieve this although the all codecs used are supported according the Philips documentation...

I did test two different .ts files both being DVB recording that I copy into an USB stick and try to play using the TV :

- 1st file : 1920x1080 H.264 Level 4 video with AC3 Audio
- 2nd file : 768x576 Mpeg2 video and Audio

When I choose the first file the TV tries to start playing and keeps displaying a black screen until I press the "back" button on my remote. When I try the second file, the TV goes full black screen for a second then returns back to the USB browsing menu.

Edit: My TV is running the latest Philips firmware and the files are played correctly using VLC or MPC on my computer.

Thanks.

Hi Attached the Mediainfo informations about the two .ts files...

Hi

can you please share a part of the 2nd Video?
1st one is out of specs as we do not support H264 on TS Files, only MPEG2.

Regards
Thomas

Thanks Thomas,

I'll share it this afternoon after getting home.

Why is the first file out of specs? It is clearly mentioned in the User Guide that TS MPEG container is supported and that H.264 is also supported. In limitations, it is mentioned nowhere that TS container combined with H.264 codec are not supported. I based my purchase on the User Guide.

Hi

Reading through the manual you should read all of it...

MPEG-4 AVC (H264)

So TS in combination with H264 > no.

Hi Thomas,

Excuse me but can you elaborate what do you mean? I don't see how your quote means no TS combination with H264.

Quote from the english manual

Playback formats
• Containers : MPEG Program Stream, MPEG Transport Stream,
AVI, MPEG-4, Matroska, Windows Media, ASF
• Video Codecs : MPEG-1, MPEG-2, MPEG-4 Part 2, MPEG-4
AVC (H264), WMV9
• Audio Codecs : MP3, AAC, HE-AAC V1, HE-AAC V2, WMA,
AC3
• Image Codecs : JPEG
• Limitations : WMA (V2 up to V9.2), MPEG-4 AVC (up to level
4.0)

You can see that containers are listed separately to codecs and that TS is part of the containers and MPEG-4 AVC (H264) is part of the codecs. There's no mapping between the containers and the codecs specifying what codecs are supported with what containers.

I think you mean by your quote that H264 is supported only with MPEG-4 container, but I'm sorry to highlight that it's not what is written in the documentation as MPEG-4 AVC (H264) is the codec and is listed under codecs. So what it means, is that this codec is supported if in use with any of the containers listed above. For instance MPEG-4 AVC (H264) with TS, or PS, or matroska...

I'm not saying you are wrong and H264/TS is supported, I'm only saying that the manual says so in its current form!

[Philips - Thomas]

Hi

Containers : , MPEG Transport Stream,
, MPEG-4,
Video Codecs : MPEG-2, MPEG-4 Part 2, MPEG-4
AVC (H264)

Yes we seperate the Codecs and the containers, yes we Support MPEG-4 Containers but only with "MPEG-4" Part 2 and AVC Codecs as you can clearly see in the List.

I'm sorry Thomas, this is misleading... When I read Video Codecs, what I understand (and what every user will), is Video Codec, Not Video Codec combination with Container! If I should understand what you said, then it means that matroska for instance is not supported with any of those codecs?

Again "MPEG-4 AVC (H264)" is the name of the codec, it can be used in several containers AVI, MKV or TS. The way it is written does not suggest by any way the limitation you are talking about.

[soussef24]

Dear Thomas,

Attached is the file sample you asked for.

Back to TS/H264 subject, you can see from this table provided by Philips a clear mapping between containers and codecs. For instance it is easy to understand which containers do support H.264 on 2011 Blueray players. It is also clearly stating MP4 container with MPEG-4 AVC (H.264) codec... Not like you said that we should understand from this statement

MPEG-4
AVC (H264)

that H264 is only supported with MP4 container!


Unfortunately the table doesn't include 2011 TVs, and the TV manual is suggesting that all supported codecs are available on all supported containers without highlighting any limitations.

Hi,
When I choose the first file the TV tries to start playing and keeps displaying a black screen until I press the "back" button on my remote.

Hi soussef24,
I have a somewhat similar issue when playing some .ts [standard def., mpeg2, DVB] files via DLNA to the TV.
A workaround I stumbled upon was when the screen goes black after pressing play simply leave the TV alone and just wait. After waiting any thing up to 4 mins or so the file starts playing! Usually it only takes 2 mins.

I know this is far from ideal but for my DLNA setup its better than nothing.

The non playback of .ts files for me only happens for a small few files I have. And usually for those problem files I have to wait around 2 mins for them to play.

Hi Mike,

Thanks, actually I saw your trick somewhere in the forum and tried it after posting this, but it doesn't work for me!

What happens with the SD file is that after black screen for 1s or so the TV returns automatically to USB browsing menu. For the HD file, it takes significantly more (few minutes), and the TV also automatically returns to the same menu!

[mike tv]

Pity about that.

Some other [long shot] ideas:
*Are there incompatible characters in the file name? try renaming it
*Try formatting the USB drive. Not sure if this is possible but perhaps try exFAT [or EXT 3?]instead of FAT32
*Try a different USB drive altogether. I've a satellite box that is very picky about the USB drives it will use.
*Are the files locked?

Hi

i have checked the File, the container is corrupt. I reinitialised the container and now everything works fine. you can check for yourself, opening the File with AVI Demux, you will see an error Message showing that there is no index.

I have attached the reinitialzed file.

Hi
I reinitialised the container and now everything works fine.

For future references could you explain how you reinitialised the ts file.
Thanks.

[Philips - Thomas]

Hi

open the File with AVI Demux, you will get a message that the Index is missing, click yes, save the file.

Thats all.

Thomas
