Sorry Beteboy,

It is similar.
The problem persists.

OK... i'll look into it....

Here is v0.71d:
http://picard.exceed.hu/tcpmp/test/t...in32.0.71d.zip

and it now includes:
- AVC weighted prediction support

CruNcher · 21st December 2005, 04:35

as soon as it supports cabac i try it

ups sorry , yeah wow this thing is fast damnit nice work Betaboy really nice playback of that 1920x1080p sample is not easy but TCPMP + CoreAVC do it perfect looking forward for a Directshow Filter and implementation into mplayer and VLC would be also nice but i see you don't want to open it for now what a pitty

Like you have another Skal on your team now hehe this Picard guy really knows low level coding it seems. Skals Decoder should be as fast as this

If the Encoder gets the same optimization cure as the decoder my my alot have to watch out and CoreAVC Encoder could be in the future on the 1 place here on Doom9 i wish it CoreCodec so much that this becomes reallity

@BetaBoy
something is strange with the ffmpeg.plg it's very slow compared to CoreAVC rendering to slow compared with a recent ffdshow build hmm seems you useing a very outdated ffmpeg with libavcodec here ?

21st December 2005, 06:48

I look forward to trying CoreAVC when binaries are available for dshow use. *Looks at Toff*

And it will be nice to have another AVC codec on the scene. By the sounds of the the quality of the decoder is very good so... Thanks for the news Betaboy and good luck with the programming for this little lot.

Plugin 'only' for TCPMP for Windows... with the new AVC weighted prediction support

DeathTheSheep · 21st December 2005, 18:19

So now it supports everything except lossless, CQM, and interlaced stuff (x264 doesn't do interlaced encoding anyway)! It's very fast, and it's optimized for the PocketPC, so it performs even better there relative to the PC.
Sony's PSP AVC decoder, shabby as it is, is falling behind rapidly, as is Nero's PocketPC AVC decoder, it seems...
The age of true handheld AVC-HP has arrived with a BOOM thanks to Picard, BetaBoy, and the TCPMP team!

I'm upgrading my 400Mhz PPC with the latest TCPMP.

currently decoding x264 (Q35) + vorbis (8kbps) = 65% realtime with FFMPEG

Sirber · 22nd December 2005, 03:58

110% with new codec

great work!!!

Sirber · 22nd December 2005, 04:17

Any clue why bench I ahve all frames while in real playback I have dropped frames? It's unfair

DeathTheSheep · 22nd December 2005, 04:20

Well, AVC is a format in which certain scenes of the video requre more processing power than others--more complex in certain areas than in others.

While benchmarking, the 110% you achieve is an average. As such, it is very inconsistent throughout the video stream--some places in the video may decode at 250% while others lag at 75%. In realtime playback, you notice the more complex places with frame drops.

Sirber · 22nd December 2005, 04:36

ok... fair enough

Also it might be my PPC, but I cannot playback from SD card

It jam after few seconds.

DeathTheSheep · 22nd December 2005, 16:58

Oh? Try freeing some ram, giving it to mostly program memory, and/or adjust the player's buffer size in the settings-> player menu.

If the problem keeps up, try uninstalling some 3rd-party programs, removing the SD card, and doing a soft-reset (keeps your data). Then try it again

HQ-LQ · 22nd December 2005, 17:28

have you already a directshow-decoder?

It is from source coode from about 3 months ago.... However even with the changes that thay have made it would not make a diff with the current code.

This is why we made the choice to do a decoder/encoder from scratch and expand our business model to include AVC as we were going to license it anyway for TCPMP and our licensees.

Toff is working on it now and we hope to have it out as soon as possible.

Scarpad · 22nd December 2005, 18:38

I've been waiting to get AVC support. I have an Axim X30 624mhz PPC, anyone using it with this hand help. I primarily want to use the files I create for my Ipod Video on the PPC. The files are only 320x240 at 768kbps

That plugin is not meant for real life usage. I'am building it with Visual Studio without any gcc inline assembly (mmx/sse). Maybe I will have look at the DivX version of ffmpeg where the assembly stuff is separated to libavdsp.

Still my favourite 64k intro

, though I haven't followed the scene much lately.
Nice work you're doing here too.

CruNcher · 22nd December 2005, 23:36

yeah picard i got your exceed background very impressive nice to see you working on multimedia solutions , and yes heaven 7 is also 1 of my favs hehe
