Is there any good PVA demuxer filter??

[Leolo]

Hi people,

Elecard's PVA demuxer is very old and doesn't support seeking. :(

Is there any other alternative for watching PVA files in Windows?

I am really fed up of having to demux all my PVA files with PVAStrumento, and then to remux them with BBMpeg every time I need to watch them. It's extremely annoying!!

To make things worse, PVAStrumento happily discards whole frames whenever it finds the slightest error in one of them :(

I've tried to ask Santa Claus, but he was too busy to listen...

Cheers.
Happy new year to everyone.

You can demux pva with ds.jar.

Hi ronnylov,

Thanks for the suggestion. I've been told recently of ds.jar, and I've started to use it a lot since then.

I need to test it a bit more, but it seems clear that ds.jar is superior to PVAStrumento in all aspects. It's more powerful and produces better results.

However, watching PVA files in Windows is still a nuisance. The whole process of demuxing and remuxing is cumbersome.

It shouldn't be necessary to go through all that hassle just to watch a PVA clip. Elecard PVA demuxer filter could be the solution, but unfortunately it doesn't support seeking. And there isn't any alternative :(

Cheers.

mplayer runs fine under cygwin, and it can decode PVA files.

I reccomend 0.90-pre2 or later.

Read the instructions to compile it against directx, everything is in the DOCS directory.

@Leolo

another possibility to watch PVA without booting a DVB card is to run ProgDVB with cmd arg /Copy, it works with elecard filters but supports seeking because it buffers the stream itself. Then WinDVBLive includes a pva ds filter that enables you to watch pva in wmp, it works with PowerDVD filters, seeking works not very well. If you have time to demux, you can automate the creation of a avs script in order to watch with Zoom Player, could easy be done with DVX

@unixfs

you mean mplayer plays pva under windows os, hard to believe

Hi Dolemite,

What you say about WinDVBLive is very interesting. I downloaded their demo version from http://www.odsoft.org/ but I couldn't find any directshow filter inside the package.

Is the filter included only in the commercial version?

Will it work also with WinDVD's audio and video filters or only with PowerDVD's ones?

Unixfs,

Sorry, but I like ZoomPlayer too much to abandon it. Thanks a lot for the suggestion, anyway.

Regards.

Just FYI, PVA format does not support seeking :eek:

btw. We are currently working on our own and free PVA splitter ... we also plan to "hack in" a seeking support ;)

Hi DAvenger,

According to the official specs:
http://www.technotrend.de/download/av_format_v1.pdf

The PVA format has PTS flags and allows byte-accurate positioning.

Why isn't seeking supported?? I don't understand :confused:

Regards.
Ciao.

Me neither :( As you can see, the specs are more than 2 years old ... so perhaps seeking was on their to-do list. Now it seems the format is not in development anymore :confused:

Hi DAvenger,

I'm eagerly looking forward for your PVA splitter filter with seeking support! If it works correctly, it would be the world's first.

The Elecard filter still doesn't support seeking (and they say it isn't planned for the foreseeable future)

And ODSoft's PVA Source filter works very very badly. It does support seeking, but the audio and video are completely unsync and the playback speed changes from fast-forward to normal every few seconds (it's EXTREMELY annoying!).

I wish you the best luck with your project.
Thanks a million.

Thanks Leolo, we're gonna need that ;) Somehow, the format is really strange and each file looks different :D Anyway, we have some ideas how to implement the seeking ... but I am not sure if it will work :confused:

Thanks

Hey guys. I've written a new filter for PVA demuxing. It's not in its best shape yet.. but it can seek :)

DGMPGDec 1.2.0 now supports PVA and you can seek in the frame served file with, for example, VirtualDub.

I assume it's not that simple, ain't it?

The latest version of Elecard mpeg2 demultiplexer (mpeg2dmx.ax)has supported already the PVA streams and navigation too. It contais in the Moonlight AVC/H.264 Decoder Package v. 1.1 build 40916, Moonlight-Elecard MPEG Player v. 2.3.2, light-Elecard MPEG2 Video Decoder v. 2.1 build 4316 packages. http://www.elecard.com/download/
