[News] MediaPortal 1.3.0 Alpha Released (1 Viewer)

[infinite.loop]

great release guys ... LAV included.. such genius =)

The genius is clearly nevcairiel, the creator of LAV. But users of MP will highly benefit from it because this will reduce the codec madness/messing around a lot.

Talking about LAVF... there is a new version available since yesterday. Now audio downmixing is supported.

We will soon update our MPEI package.
Users can simply update LAV then by launching the MediaPortal Extension Installer.

@infinite.loop: as i wrote it is just my opinion. I know perfectly that issue in Mp are caused by different clocks between a/v.
But i prefer much more miss one video frame every 20 min than lost completely original audio track (a part of you say that is impossible to hear difference, so why publisher included HD and loseless audio tracks in BD ?) . And i still wonder why other players and tv software don't suffer this clock drift ?

@Holzi: Please , reclock was made at the start of Htpc age, when Hw was just sufficient to play mpg2 streams with 5.1 ac3 audio. Now in HD age i really think it is just a workaround for who owns crappy hw or not good software.

peace and love

99% Marketing.
What most users do not know is that majority of movies were produced in 5.1. Yet on many BR's you see stickers like "thrilling 7.1 Surround Sound!" which is just an attempt to sell more units. The additional 2 Channels are upmixed, which your AV-Reciver can do as well and most of the time with better results.

The "lossless" sticker is another example of marketing, which many users jump on.
To really hear and feel (50Hz) the difference between i.e. a normal DTS stream and MA you need very high quality/expensive Audio Hardware. With the hardware most users have in their livingrooms, you can not hear a difference due to the quality their speakers, amps, etc. have.

But this is not the aim of MPAR. MPAR is meant for users who foremost want a smoooth video playback.

And i still wonder why other players and tv software don't suffer this clock drift ?

If you play a video that has 24FPS on a display that runs at 60Hz, then you will have stuttering due to dropped frames. It is as simple as that.
If your player does not produce stuttering due to the FPS/RR mismatch, then it is doing processing to compensate. Very much as MPAR does.

But there is no real point in arguing I think.
We provide our community with an option to choose on their own. Users who don't notice the slight stutter, or don't suffer from it, or just prefer bitstreaming over a smooth videoplayback don't have to use MPAR.
Users who foremost want smooth videoplayback will enjoy MPAR very much.

MediaPortal was and always will be about flexibility and choice. MPAR is another great example of that philosophy.

LOL. i missed that....so Mpar (as reclock) helps who owns a not sufficient hw in that case the TV.
So why worry about re-encoded audio when play video on crappy display.
Thank you
Finally i understood before i thought mpar is also for who uses dynamic refresh changer and sync frames. i'm very sorry.

i TOTALLY agree

LAV MPEI Package updated to 0.51. If you installed 1.3 Alpha already, update it via Extension Manager. Everyone installing the Alpha now should already get this new version installed, as the MediaPortal Deploy tools always downloads the latest version.

Please, before starting to distribute false claims take some deep dive into the MPAR source code and learn how it works. If something is unclear please ask from the devs first than just make assumptions that might be false. In previous post there was many false claims, but I wont correct those yet (not enough free time at the moment).

@infinite.loop: as i wrote it is just my opinion. I know perfectly that issue in Mp are caused by different clocks between a/v.

MPAR wont do anything for the audio when display refresh rate and fps are matching for 99.9% of the time (this varies between 99.0 and 100.0% depending how the audio and video hardware clocks work). In such case MPAR will enter into a quality mode where reference clock corrections (timestretching) are needed. For your 20 minute dropped frame case it would be happening once per 20 minutes and for a quite brief moment. For the remaining time the lossless LPCM stream is passed thru (unless channel mixer or some other feature is required to be used to convert the stream to the output devices format).

If there are some unclear behavior with the MPAR (or any other new functionality) it is much better to open a new thread than to start to spread false information. In any case such deep in technical detail discussions aren't shouldn't to be handled in release news comments.

I note people are reporting issues in the LAV thread http://forum.doom9.org/showthread.php?t=156191&page=579 with changing channels in DVBviewer (something to do with DXVA apparently).

Will the versions of LAV supplied/downloaded automatically by MP be checked to make sure they don't contain bugs that crash MP, or will it just download and install whatever the latest available version is?
