BDP3200/12: no video on HD-DVB-C recording in mkv-container

[flensrocker]

Hi,

I recorded some videos from german cable tv ("Das Erste HD", DVB-C, HD, 720p50 with AC3 audio). The video plays fine on my PC and on my second Blu-ray player (LG BD370). Unfortunately the BDP3200/12 (with firmware from 11.07.2011, serial begins with GS) doesn't show any video, audio is fine. It is connect via HDMI to a Denon AVR 1611 which is connected to a LG 42LD7020. Playing DVDs and Blu-rays or MPEG2 videos from USB is working fine.

I tried several tools to create a mkv- or avi-file (without reencoding the video, I would like to keep the original) from the elementary streams (demuxed with tsmuxer), namely mkvmerge, GDSmux, avidemux (on Windows platform).

Here's what MediaInfo says about the streams:

Comparing the data to the manual it should be supported.

If I configure the player to use the native resolution on HDMI output my TV switches to 1280x720, so it seems it copes with the file in general. But all I see is the blu background image...

Has anyone successfully created a mkv-file with streams like these?
If you need more information, just ask. ;-)

Lars.

Hi,

I would try with lower Reframes: 4 it should be ok.

let me know if it works

[flensrocker]

Hi,

I thought I could avoid reencoding the video because of loss in quality (and effort of time of course)... But I'll will give it a try for testing purpose.

Thanks!
Lars.

[flensrocker]

According to http://www.supportforum.philips.com/...2&d=1305807479 the supported framerate varies from 6 to 30. I will also try a recode to 25fps the next days.

Lars.

[Kiro]

Yep, you're right!

I didn't notice the 50 fps

I reencoded the video with x264 and 50 fps but 3 ref-frames. Now the player has no problem. Seem's you were right. :-)

Now I can think about reencoding all my videos or find another solution...

Thanks!
Lars.

Hi,

I made some tests with different encoder settings. The player plays 720p50 video with 5 ref-frames.

Here the info of a playable video:

Anyone from Philips around who knows why the video from the first post isn't shown? It would be a pity if I have to reencode all my videos since there's always a lost in quality. And since there are Philips TVs which can display german DVB-C HD content (Das Erste, ZDF, arte) I'm sure it's possible to teach the player to also playing it.
Maybe I only have to patch a certain header field cause the firmware chokes on some bits?

I contacted Philips support today with the same problem. The differences I found are in the GOP settings (GOP : M=16, N=32) which are not shown in the last file.
Still waiting for a response from Philips. I have several HD recordings from ARD, ZDF and ARTE burned on BlueRays. My old Samsung player has no problems with those disks, but my new BDP 5200-12 can' play those disks.

Hi,

did you test it only from BD or also from USB... sometimes there are differences...

Toengel@Alex

I tested it from BD-R and also via USB. The same result. My test file is 20MB. I would very much appreciate to email this file somebody who can test this with the BDP 5200-12.

Hi,

you can upload the video somewhere (e.g. megaupload)... and post the link.

Hi,

Nice to hear that I'm not the only one. Which tools do you use to get the video properties? Something different than MediaInfo?
I will try to re-encode the video with x264 and some settings to get as close to the original settings as possible to detect the culprit.
As written my LG BD370 plays this video without any problems, too.

Lars.

I'm using MediaInfo. Other tools show the same.

I will try to re-encode the video with x264 and some settings to get as close to the original settings as possible to detect the culprit.

I did that already and suppose that the gop structure is the culprit. *Format_Settings_GOP : M=16, N=32*

Yes, I read your post. I will double check, just to be sure.

Thanks for your help!
