New Panasonic Profiles Requiring Testers.

[voodooo]

Nice. Will test this tonight. Can we transcode based on video bitrate ? Cause what you're doing now is transcode based on profile level and has you said its a shame we have to include the good and the bad ones in the same "bag"..

I think I haven't mention this before, but, when transcoding mkv they do not stutter, they only stutter without transcoding. So theres no need to limitthe bitrate in transcoding I think.

dunno thats a question for zip but i can only limit bitrate on transcoded files, but hopefully that now solves the stutter issues, but MKV may still stutter at the moment will look at that next.

ok so video bitrate is an issue then id guess, try adding this to the profile, its almost what PMI had in his profile with slight edit, real shame we have to transcode these files though.

I did not mean to say that! That would take away one of the reasons for getting this model TV. This is why I left of the max bit rate, because I do not know what it should be. I believe the TV should be capable of pretty high bit rates.

It was only one way to solve a problem when the number of reference frames is high. I think the reference frames just fill up the allocated memory, but I was only just starting to work on that when you posted the new official profile.

When you have HD video, the frame resolution is higher, so a reference frame takes up more memory... so if you have more than about 4-5 reference frames, the memory buffer allocated for this by the decoder fills up...

(not sure I am explaining this very well)

The video Level is increased only coincidentally with the number of reference frames at high bit rates.

Bit rate should not be an issue with sane reference frame use, but not all programs that encode to MKV/H.264 will follow that, and a few people encoding certain types of animated films may actually need the higher ref frame numbers for good quality.

@cerberus: For a change, here is a simple one:

Viera E-series does not seem to support MPEG version 1. (this is from tests with your profile posted above)

This is strange, because it definitely DOES support MPEG version 2. This affects older music videos originally recorded in NTSC and distributed as MPEG.

I have a few of those, but some people have hundreds because they were basically given away to promote music CDs, and even though the video quality is poor, sometimes the performace and the audio are very good.

I just force Mpeg v.1 to transcode to v.2 but perhaps you have a better way.

Here is the Media Info for one file:

[Cerberus]

mpeg 1 i will deal with shortly i did read an early topic about that, and yes its an easy fix. ( i asume that they are in mpeg container, if so that fixed in my profile i have ready to go if we sort the stutter )

ref frames should not be a problem once the level has been changed, the bitrate i set is same used for the samsung BDP to help with stutter so hopefully will help here but i need you guys to test and give me the info on file that still have issues.

I have Panasonic P42GT30E. Which one is the correct testing profile for me?

At the moment I am with "Panasonic Viera (E, G-series)". Most important for me is subtitle support. I prefer not to able to play some files, and to have all possible subtitles, rather than oposite. At the moment found external subtitles working whith AVI containers, and internal subtitles working with MKV containers whithout transcoding. Is it possible to have external subtitles and transcoding?

The attached file was transcoded. Video and audio is ok no subtitles.

Changed levelGreaterThan to 4.2 and removed
<Matches container="matroska" vCodec="h264" aCodec="dca" />
in order to play it whithout transcoding. Now all is played correctly (audio,video, subtitles).

[Cerberus]

@ICO please look on the first post it has the two profiles take the one for your model. ( yours HAS avi support )

Changed levelGreaterThan to 4.2

only strating work on profile lvl they have not been fully added to the profiles but greater than 4.2 rather than 4.1 is fine, still waiting on feed back from teh other testers.

removed <Matches container="matroska" vCodec="h264" aCodec="dca" />

this has already been done for your model, if you use my profiles on first post.

subtitles

havent looked at this yet but from what you said thats not an issue and will change the profiles now.

[iCO]

Whith "Panasonic Viera With AVI Support" the above file does not play at all. Receive "The file is not read" on the tv set (not sure about the exact message in english). The same is with several other MKV files I've tested.

comented out:
<!-- <Matches container="matroska" vCodec="h264" /> -->

Now file plays ok.

hmm thats odd one then, ok will look into this and please see my previous message about profile lvls and subtitles.

can you provide mediainfo readout on that file please. so i can see what exactly is happening.

You have 2 subs inside the mkv with different formats and different languages, try to remuxe again and remove the one you don't need.
And there's no need to transcode cause both audio and video should play without transcoding on your TV.

voodoo can you confirm SOME MKV with h264 video will play without transcoding as long as they are below profile level 4.2?

Yup. If tested at 1920x1080 4.1 profile and the only one that stutter (without transcoding) have 10+ Reframes. DTS/AC3/MP3 audio should not be a problem either.

is that with

              <Matches container="matroska" vCodec="h264" />


removed from the profile ???

I have transcoding disabled globally Just enable it to test some profiles/files. I bought this TV cause it support the majority of the codecs i need..

Different from files posted above (MPEG v.2 in MKV container), and does not play at all. Generated using MakeMKV. Should only require remux into MPEG-TS container with no transcoding. Have several of those.

ok well its not refframes then as the working file has 5 reframes and one of your failed file has 5 reframes too, so must be something else.

@voodoo - thats not transcoded that only remuxed, so try removing it and playing your files.

@pmi - can you do the same remove that line and then try playing the woody_allen_5 file

that would follow with what " iCo " said so try removing this line and then see if files play

  Code:

<Matches container="matroska" vCodec="h264" />


if that works i will update first post with new profile to test, but i have nasty feeling we wont completely beat the stutter issues.

[PMI]

MKV with H.264 encoding and AC-3 audio, or AAC audio play without transcoding.

WITH transcoding they do play, but HD video quality is not as good, and in some scenes, just plain bad. I do not think this is a profile issue, so not relevant in this thread if you just want to know that the files play... (not trying to be an ass, just mention for completeness)

Same in the case of MP4 files, H.264 and AC-3 or AAC plays.
