I wrote a program that supports few webcams. You can have a look at :
http://amigadev.free.fr/sonix/

I added the network support to push images to an FTP server with a given delay.

Our problem for speed and microphone support is the lack of the isochronous mode. So, the bulk mode has to be used but very few webcams support it.

I would be proud if you could use this program at the show and I am ok to send you a working webcam (I have several ones).

@Samo79
Thanks for the news ! About Dosbox 0.73 I stopped to investigate for optimization : I tested dozens of approaches and the code design made me crazy !

@Slayer
Thanks ! I appreciate but I do it for fun and I prefer amigans to save their money to buy hardware or contribute to software developers that needs money.

@kas1e

I fully agree with you. UtilityBase is a very good site with a positive atmosphere, helpful discussions ... all stored in the database, what makes a huge knowledge.

But I am annoyed regularly by spams ... and I was ignoring there are web viruses. I am not a web specialist and I don't know how to fix that but Utilitybase must be safer, with the current framework or another one.

@Alex_C

I identified the problem with a small example that reproduces it but I can't fix it by myself ... except if I have access to the OS4 source code of course :)

I hope it will be fixed soon (will we have a new update this summer if the X1000 comes out ?).

@Alex_C

Unfortunately, I have to say that Hieronymus doesn't work on neither boards (Sam and Pegasos). I identified the problem and filled a bug report and I hoped it would be fixed in the new OS update.
I haven't checked but you did and it still fails

I am sorry about that.

@Helgis

Another advice : start with small programs. When porting a program, it may compile and run magically but there are often things to fix, so be prepared !

Good luck !

Contrary to the PPC400, the PPC460 has a L2 cache (256 KB). It also have an improved FPU, a PCIe controler, a higher frequency and possibly a faster memory.


@ACube : Great news ! The 460 is really nice and I hope you will find a market for it. Thank you really much for your very good work.

@phx

Great ! I am happy to see that allows to make a step forward. I have no doubt you are preparing something great (as usual).

I understand you can't be part of the maintainers ... I could be interested in that. I have many other projects but there are so many programs that uses SDL libs that we need a good process to compile, test and provide these libs.
I asked the opinion to Xeron but I have no answer yet. I also discussed all that briefly with HunoPPC that did many ports and knows well SDL, problems, required enhancements, ...

In my opinion, we should have :
- A centralized website (the Google's one) with sources (SDLlibraries, the main one and others), bug tracker, ...
- A way to build and test these libs
- That could provide libs for OS and SDK updates
- These libs could be put on os4depot that is a well known path when you search for stuff

soptUP : The first step was to build the lib with major formats supported. I wanted to go fast in order to provide the lib to phx. To finish cleanly, I will have to support additionnal formats, write a readme, test with other programs (thanks for the link !) and upload it on os4depot.

@phx

I've just uploaded here the libraries I compiled. I hope it will help and ... work !
The library supports libmodplug.

A new post again ...

How to compile SDL_sound 1.0.3

Download and install libmodplug from : http://os4depot.net/share/development/library/audio/libmodplug.lha
Download and unpack sources from : http://icculus.org/SDL_sound/downloads/SDL_sound-1.0.3.tar.gz

Then, in SDL_sound-1.0.3/ :

sh

./configure --disable-dependency-tracking --disable-sdltest --disable-wav --disable-raw --disable-au --disable-shn --disable-voc --disable-midi

exit

In config.h, set manually :
#define SOUND_SUPPORTS_MODPLUG 1

make

Compilation hangs, so go into playsound/ and run these commands if you want final executable :

g++ -g -O2 -I/SDK/local/newlib/include/SDL -D_GNU_SOURCE=1 -o playsound playsound-playsound.o playsound-physfsrwops.o -use-dynld ../.libs/libSDL_sound.a ../decoders/.libs/libdecoders.a ../decoders/mpglib/.libs/libmpglib.a -L/SDK/local/newlib/lib /SDK/local/newlib/lib/.libs/libSDL.so -lmodplug -lauto -lm

g++ -g -O2 -I/SDK/local/newlib/include/SDL -D_GNU_SOURCE=1 -o playsound_simple playsound_simple.o -use-dynld ../.libs/libSDL_sound.a ../decoders/.libs/libdecoders.a ../decoders/mpglib/.libs/libmpglib.a ../.libs/libSDL_sound.a -L/SDK/local/newlib/lib /SDK/local/newlib/lib/.libs/libSDL.so -lmodplug -lauto -lm

I hope we will find a satisfying solution, ending with an upload of SDL_sound on OS4 in a first time.

I fully agree we should centralize SDL libs. This seems to be the only way to reach a good quality (with bugtracking) and guarantee libs availability to developers for a better efficiency.

About SDL_sound, the build seems to be half broken. I had to compile playsound manually and this one ... link GL libs by default (hum ... maybe due to SDL config ?).

Great ! I am playing a module with playsound, the test program compiled with the SDL_sound sources.

@phx

I know you do so much for us that even if I have my own projects, I tried to save you some time.
I failed having these errors :


Ok ... I've just succeeded in compiling playsound adding manually :

../decoders/.libs/libdecoders.a ../decoders/mpglib/.libs/libmpglib.a

I tried 3 mp3 files and two failed with an error. The third one works well !

I can send you these files if you want.

Which formats do you need to be supported ? I see that in the configure log, libmodplug was rejected because the built test program does not compile because of C++ stuff ... I suppose it is not compiled with the good options. I try manually.

@phx

Yesterday evening, I noticed HunoPPC about this question. As he has ported many SDL games on OS4, he knows well the availability and the problems of these libraries. He could have a good advice. Else I am afraid nobody has already ported/used SDL_sound ...

I've just tried to compile SDL_sound this morning without the support of some audio formats but it still stops linking playsound. At the moment, I don't know why ...

@SIID

You give your opinion but it is sad to read that. As I am at the party organized by HunoPPC, I tried yesterday evening this game and it runs perfectly. The gameplay is not so convenient for me but you know, my game is programming. Else, the games may look old with textures from 80's but it is fully matching the Sonic atmosphere.

HunoPPC : Trust me, you did a great work again and I am proud to see the result before (almost) everybody.

More news to come today :)

I always wanted to do that ! And visit Norway of course ! Maybe in the future ...

About the meeting, if it stands this month, it is too late to prepare but what about go there, discuss, see the potential, build a group, ... all that in order to prepare the event next year.

@Antique

Norwegian users should find a way to have a booth at this show !

At Primevere, there were thousands of visitors, 450 exhibitors and 120 conferences planned. I was there yesterday to promote our hardware and software with the TripleA team and didn't have time left to attend conferences unfortunately.

We spent the whole day discussing, explaining, ... to people who were very interested and amazed by what they were seeing. A great thanks to Edgar and its AmiCygnix because showing programs like Gimp or Gnumeric was a big argument talking about availability of well known applications.

Sam440 was appreciated for its features : low consumption, silence, ... and still enough power with an efficient OS running on it :)

I think reproducing attendance to several non-Amiga shows will really have concrete and positive consequences.

@Antique

I am sorry but even if the subject of the thread mentions Ringhui, it doesn't say that you look for information or examples.

I am sorry again : I haven't tried Ringhio and the notification system yet even if it's a great feature in the last version of OS4.

@acefnq

What is the value of the parameter Cycles in the config file ? Did you set it to "max" ? If I remember well, I chose 3000 cycles. Maybe you could decrease this value.

With 100% CPU, we know that there is not enough CPU power, so reducing the workload, to 80% for example we could see a difference.

@others : Any results ? Not interested in dosbox ?

Oh ... for people who will test, please tell me what is the machine you use. Thanks !

@acefnq

There are tools on os4depot :
- cpuwatcher
- cpuinfo_docky

They show the CPU activity (how many percents are used).
