Problems with h.264 streams from DVB-S2 Broadcast

[OliBoe]

Hi,

i´m using a Kathrein UFS-922 DVB-S2 Receiver (HDTV) which can be accessed via FTP (LAN) and therefore normally I transfer my recordings (SKY Pay-TV with Sky HD and Disney Cinemagic HD) to my computer, use TS-Doctor to correct the errors in the DVB-S2 stream and then store the .ts files on my DS-209 NAS. I play this movies with my two PS3 (old 40GB modell and a new slim one) and everything works fine.

The public-law broadcast stations ARD and ZDF (like BBC in the UK) will start with 720p HDTV with the olympic games and they start some test-cases at the christmas holidays.

And that´s when my problem starts....

Sky HD and DisneyCinemagic HD (and Discovery HD) are AVC in 1080i (25fps).

ARTE HD (Arte is a joint public-law broadcast from germany and france) is - as the public-law broadcast in germany will be from later this year - AVC in 720p (50fps)

ARTE HD recordings work fine but the recordings from the christmas testcase are full of artefacts and studder every 10-30s. I tested this and that but playback on my computer is everytime with these artefacts (and studder).
Playback with both PS3 is with artefacts (and studder) too - but only 10% of the problems I have on my computer.

Surprisingly other users (from a TS-Doctor forum) have NO (!) problems by playing this EinsFestival HD (public-law broadcast) recording at least one using CoreAVC 2.0 codec.

So here is the test-stream (30s snapshot - 36MB):

So, here are the results of this test-file:
- my own Win7 PC with VLC-Player: Artefacts
- Playstation 3 (old modell): Artefacts
- Playstation 3 slim: Artefacts
- Other users computer with CoreAVC 2.0: perfect without any problem
- Kathrein Receiver (own recording): perfect without any problem
- Kathrein Receiver via DLNA: perfect without any problem

So I tried MediaInfo to look after the differences between the working ARTE HD recordings and the non-worling EinsFestival HD recordings.

Here is the result: (Sorry that it is in german but I think that everyone can imagine what is meant...)

So...
What I don´t understand is the fact that the recording should be okay because the DVB-S2 receiver is capable of playing these recording via his own archive without any problem and via DLNA without any problems. But the PS3 - the beast which plays nearly everything will cause artefacts as well as my computer.

Does anyone has any idea?

It works without any problems in FFDshow r3178!

Works here too with recent MPlayer SVN and VLC git builds (didn't try 1.0.x or older)

[CruNcher]

CoreAVC 1.9.5 Software = No Problem
CoreAVC 1.9.5 GPU = No Problem
Mplayer = No Problem
VLC = No Problem
FFdshow = No Problem

Hmm if the PS3 has really problems maybe a Firmware update gonna help ?

[OliBoe]

It´s nearly unbelievable...

I tried yesterday evening everything.
De-installed all codecs and Software-Player like PowerDVD.

Installed the newest FFDShow Filter...

Test these and that - but the result is everytime the same.
VLC plays the stream with some stutter, MS Media Player with much more stutter.

PS3 plays the original stream with stutter, the test-stream (link above) with stutter, a converted stream (tsRemuXeR) to m2ts with stutter...
And both PS3 has the same and newest firmware!

I found someone else from germany (from another forum) who has similar problems with his recordings from the same broadcast and his PS3.
His solution is to reencode with sx264 - but I wont reencode the movie...

I´ll try to install Windows 7 completly new on my laptop.
It was a Vista upgrade and maybe a clean installation will help...

Was anybody able to test the test-stream on a PS3?

Best regards,
Oliver

sx264 - but I wont reencode the movie...
If you need some help with that I can probably help,.. (since I'm the author of sx264&hybrid ;))

Did you select ffmpeg-mt for H.264 decoding? Which DirectShow player do you use and does ffdshow get loaded when playing the video (there should be a tray icon)?

Test these and that - but the result is everytime the same.
VLC plays the stream with some stutter, MS Media Player with much more stutter.


Which CPU do you have? My 2 GHz Core 2 Duo is just about fast enough to decode your sample with libavcodec on a single CPU core. If you have a slower CPU, there will be problems with VLC. How high is the CPU load during playback?

You could also try DiAVC or DivX decoder with some DirectShow player (MPC-HC, for example).
