Samsung ue32B7000 and H264 content
This television supports the formats listed in these pics
link1 link2 link3 I have some H264 files in Matroska container. Mkvinfo reports Codec_ID:V_MPEG4/ISO/AVC Now the fact is my TV doesn't recognize the video format: it tries to open the files, then outputs an error saying "unsupported video stream" or something like that. But again this TV is able to decode H264 but evidently in another format. I don't know all kind of different formats for h264 out there, and i am particularly not familiar with BP MP HP. All the more because i use GomPlayer on my pc and the files play fine. What exactly should i transcode to? Is there any easy transcoding i can do instead of full reprocessing? |

at least the second picture states that the player should support: mkv+avc base/main/high profile+(he-)aac/mp3
(bp = base profile, mp = main profile, hp = high profile) so unless the file uses lossless compression the player should be able to play it,... -> post some additional infos about the file (e.g. like from: mediaInfo --Full File.mkv) |

The TV probably can only play files up to level 4.1 which means maximum of 4 reference frames at that resolution. You've got 16. The old b-pyramid might also cause problems if you didn't have way to many refs to begin with. Apart from that I don't think you have any problems, but the only way to fix it is to reencode.

I did have some background when DivX was all there was, now i'm totally lost on details. What tool should i use to reencode and with what settings? I don't know what b-pyramid is. Should i? About the 4.1 yours is a guess i guess :P I doubt there is such info for such a consumer device... Also where did you find this b-pyramid? I can't find any reference in the info i posted. ReFrames are selfexplanatory, b-pyramid is a blank to me. And since you suggest to reencode, would it be good to use another codec with fewer possibile incompatibilities with my tv? Like mp4?

The only thing you need to change is the number of reference frames as far as I can see. If you look at the Wikipedia article about h.264 you can see that the level is a set of restrictions on your video. Most hardware decoders that do High Profile can decode up to level 4.1 because that's more or less what blu-ray uses. On of the restrictions the level imposes is the Decoded Picture Buffer size, which limits the number of allowed reference frames. You can only fit 4 1920x1080 frames in the DPB at level 4.1, but you'd have to fit 16 in order to play your file.
By the way the information about what level your TV can decode should be available somewhere because the profile and level the decoder supports tells you all you need to know about it's playback capabilities. Unfortunately many vendors are sloppy when it comes to putting up accurate information. You can see that b-pyramid was used in the "Encoding Settings" line. In earlier versions of x264 using b-pyramid wasn't entirely spec compliant, but that was fixed so you don't need to worry if you do encodes now. I wouldn't use a different codec, because in my opinion h.264 gives you the best quality/filesize from the options available and should be future-proof when it comes to hardware support. By the way mp4 is a container, not a codec. A bit more limited than mkv in regards to what you can put in it, but has a little better hardware support. edit: Oh damn I didn't look at the filename. Sorry mods. Last edited by nurbs; 8th November 2009 at 18:22. |

Thanks i'll try.
I found mediacoder which seems to be using my gt8800 for encoding. Should speed things up a bit. I'll try setting a profile 4.1 and see what i get with my tv. Update: i used mediacoder with cuda and profile 4.1. Now it works. I am unable to see if there is any quality difference. But i think i'll stick to this for now. Thank you very much!

Hi,
I have the same model of TV and I have a strange problem with a mkv file. I read the discussion but i don't unserstand my problem. In fact my mkv file has the 4.1 profile. I post the info result using mediainfo: Code:
