in my following code i try to realize videoconference with my friends. what i do is sendin an integer (how big is sound-chunk) - the sound chunk - an integer (how big is jpeg) - the jpeg. server sends same with one byte (ID of the user) to all the other connected users.

http://pastebin.com/0tv8RR2M

picture comes instantly but sound 2-3 seconds later. is it possible to decrease sound latency?

thanks a lot for fixing this! and a lot of thanks for making so great libraries, very useful! in the next step you can make it possible in bassenc server to send icy info.

chan1 = BASS_AAC_StreamCreateFile(FALSE,datei,0,0,BASS_STREAM_DECODE);
chan3 = BASS_AAC_StreamCreateFile(FALSE,datei,0,0,BASS_STREAM_DECODE);

mixing = BASS_Mixer_StreamCreate (44101,2, BASS_STREAM_DECODE);
BASS_Mixer_StreamAddChannel (mixing, chan1, 0);

mix2 = BASS_Mixer_StreamCreate (44100,2, BASS_STREAM_DECODE);
BASS_Mixer_StreamAddChannel (mix2, chan3, 0);

enc = BASS_Encode_StartLimit(mixing,"aacplusenc - - 48",BASS_ENCODE_LIMIT,0,0,100000000);
BASS_Encode_ServerInit (enc, radioport, 560000, 480000, 0, servfunc, NULL);

enc2 = BASS_Encode_StartLimit(mix2,"aacplusenc - - 48",BASS_ENCODE_LIMIT,0,0,100000000);
BASS_Encode_ServerInit (enc2, "0.0.0.0:8050", 560000, 480000, 0, servfunc2, NULL);

enc with BASS_Mixer_StreamCreate (44101... you can listen to with http://djtraumwelt.de:8000
enc2 with BASS_Mixer_StreamCreate (44100... you can listen to with http://djtraumwelt.de:8050
should be online 24/7
port 8000 with a different sample frequenzy 44101 instead of 44100 he is resampling and sound is good
port 8050 with same sample frequenzy he isnt resampling and sound is overdriven, much too loud and bad.

i solved it with using 44101 as sample frequency
but it would still be nice to solve it in the libbassmix.so

This works perfektly, BASS_Encode_Stop is closing the server, starting it again is working fine =) thx a lot.

but another question: is it possible to send icy-info when an other song is played? like shoutcast or icecast do.

I have a problem with bassmix: sound is bad when source channel has the same sample frequency than the mixer channel. when i have different sample frequencys the sound is good. but only 44100 and 48000 works to play back with the win32 vlc, what the encoder on a linux machine is outputting. now i have files with 44100 and files with 48000 and i want all the files to get worked.

or, is it possible, to make an encoder that is used by the server and a real encoder and then copy from the real encoder to the encoder that is used by the server, so when the real encoder dies, i can open a new encoder and then copy from the new encoder to the encoder that is used by the server?

how can i kill a server that i started with BASS_Encode_ServerInit?
if the encoder dies, i have to kill the server and start both again.

i want to write something like the shoutcast server that has a source port, where i can upload my moderation speeking in mp3. i tried to write a client source prog that sends the mp3 data like this:

void CALLBACK EncodeProc(
    HENCODE handle,
    DWORD channel,
    const void *buffer,
    DWORD length,
    void *user)
{
send (sock, buffer, length, 0);
}
...
BASS_Init(-1,44100,0,0,NULL);

    BASS_RecordInit(-1);
    hrec = BASS_RecordStart(44100,2,10<<16,0,0);

    BASS_ChannelSetAttribute(hrec,BASS_ATTRIB_VOL,(float) 1.0);
    mixing=BASS_Mixer_StreamCreate(44100,2,BASS_MIXER_NONSTOP);
    BASS_Mixer_StreamAddChannel(mixing,hrec,0);
BASS_ChannelPlay(mixing,0);
...
enc = BASS_Encode_Start(mixing,"lame -q 0 -b 32 -",BASS_ENCODE_LIMIT,EncodeProc,0);

and my server prog on a linux vserver:

void CALLBACK MyFileCloseProc(void *user)
{
return;
}

QWORD CALLBACK MyFileLenProc(void *user)
{
    return 100000000; // tried 0 then doesnt go forward
}

DWORD CALLBACK MyFileReadProc(void *buffer, DWORD length, void *user)
{
recv (sock, buffer, length, 0);
    return length; // read from file
}

BOOL CALLBACK MyFileSeekProc(QWORD offset, void *user)
{
    return 0; // seek to offset
}
...
chan2 = BASS_StreamCreateFileUser(STREAMFILE_BUFFER, BASS_STREAM_DECODE, &fileprocs, 0);
enc = BASS_Encode_Start(chan2,"aacplusenc - - 32",BASS_ENCODE_LIMIT,0,0);
BASS_Encode_ServerInit (enc, "8000", 32000, 32000, 0, servfunc, NULL);

and now, i cant hear my voice. the client sends some data and after few seconds it stops sending data. playing the radiostream with vlc fails. the server isnt sending anything. playing and encoding mp3 files on the vserver works and vlc is playing the sound and receiving data.


I need an example, how i can get the dj source working.
thanks for reading this

this one works perfektly =)
a lot of thx!!

i get error while loading shared libraries: /usr/lib/libbassenc.so: ELF file OS ABI invalid when starting a programm that uses libbassenc.so with the version of 18 mar 2011. maybe theres something wrong with this new version of libbassenc.so. can you upload an older version? i didnt save it.

equ1.lFilter = BASS_BFX_BQF_HIGHPASS;
equ1.fCenter = (float) 4000.0;
equ1.lChannel = BASS_BFX_CHANALL;
equ1.fBandwidth = (float) 2.0;
equ1.fGain = (float) -15.0;
hfx1 = BASS_ChannelSetFX(chan1, BASS_FX_BFX_BQF, 1);
printf ("%d\r\n", BASS_ErrorGetCode());
BASS_FXSetParameters(hfx1, &equ1);
printf ("%d\r\n", BASS_ErrorGetCode());

getting 1 and 5
whats wrong

edit:
getting 19 and 5

edit 2:
BASS_FX_GetVersion(); and it works

the renter of my vserver has an option "install another image" and i installed opensuse 11.0 and on this system the autodj works without memory leak. thank you very much for supporting me!

i called this pmap on start and got the same output later. ps xv|grep autodj shows, that there is no memory leak on my home computer. it must be one of the libs on the server. i will contact the renter of the server, if he knows, where the problem is.

on my server is debian lenny5... and on my desktop at home too. on my server pmap shows nothing and on my desktop at home it show the info we need. thats very mysterious.

think, that this means, there are no files in cache, right?

edit:
when i remove the bassenc stuff, that helps nothing. the problem is anywhere else

thats to difficult for me. go slowly, please. linux caches the files. how can i see, if thats the problem and how can i free this cache?

it uses always more memory, when the next song is played. not faster and not slower. on my server there are 512 MB memory and on starting my autodj it uses 0.3% of this space and one day later it uses 4.5%.

thanks so far and greets from germany (thats the reason for bad english, if there is some)

edit:
it is the process's memory usage, because i mean the usage of the output from 'ps xv|grep autodj' - there the system shows 0.3% and 0.7% an hour later...

this is my autodj and always when the next track is playing, more memory it uses. more and more and more. anyone here, who knows the reason?

a lot of thanks! it works now.

maybe a lot of djs could need this programm? i dont know anymore, where to get aacplusenc for linux, just ask google and with this program, the auto dj (shoutcast trancoder) can send in aac, helpful to get users, that have a slow internet connection.

this is what i have, but it doesnt work and im on my end of know how.
this programm doesnt show any numbers, it shows nothing, aacplusenc is running, but server is down.

I tried to write an audioplayer, that streams to a shoutcast server. encoding with lame works. encoding with enc_aacPlus doesn't. why?

when i encode with "enc_aacPlus.exe - - --br 32000 --he --silent --rawpcm 44100 2 16", the bass libs send 15% of the mplayers buffer and than stops sending data. it looks, that the encoder doesn't work correct. i even tried other aac encoders like faac or what ever i found in google. no aac encoder did work. what do i make wrong? can someone help me?
