[vlc-devel] Transcoding with API 0.9.0

[jf massol]

Hello everybody,

I fixed my API problems (0.9.0). I followed API guidelines given. But I'm
facing a problem, within API, as argv arguments given (mainly for
transcoding), I got those error messages :

/* error messages */
[00000328] stream_out_standard private error: no access _and_ no muxer
(fatal error)
[00000327] main stream output error: stream chain failed for
`std{mux="",access=""#transcode{vcodec=mp2v,vb=512k,scale=1,acodec=128,ab=128}",dst="duplicate{dst=std{access=file,dst=/home/videogate/FRANCE.ts}}""}'
[00000326] main input error: cannot start stream output instance, aborting
[00000317] access_mms access error: error while asking for file -1
[00000317] access_mms access error: error while asking for file -1
[00000317] access_mms access error: cannot connect to server
[00000317] access_mms access error: no stream selected
[00000317] access_mms access error: cannot start stream
/* ************ */

and this is my source code :

int Transcoder::transcoder_init()
{
    cout << "Transcoder_init() : " << this->home << endl;
    string trspts =
"\"#transcode{vcodec=mp2v,vb=512k,scale=1,acodec=128,ab=128}:duplicate{dst=std{access=file,dst="+
this->home +"}}\"";
    char *opts[] = {"vlc","--sout",(char *)trspts.c_str()};
    libvlc_exception_init (&_transexcep);
    _transcoder = libvlc_new(3,opts,&_transexcep);

    if(libvlc_exception_raised(&_transexcep))
    {
            cerr << "Transcoder init : " <<
libvlc_exception_get_message(&_transexcep);
        MSG_GENERIC("Cannot init Transcoder")
        libvlc_exception_clear(&_transexcep);
            exit(1);
    }

    if(_transcoder == NULL)
    {
        cerr << "No Transcoder instance found !";
        MSG_GENERIC("Cannot init Transcoder")
        exit(1);
    }

    MSG_GENERIC("Transcoder successfully initialized")
    return 0;
}

My VLC instance is successfully initialized. But I don't understand why a
"std{mux="",access=" in addition to my args ?
Is there a special format for argv in order to transcode my streams ? When I
tried "-vvv", it works fine, but no way for my transcode args.

Thanks a lot one more time.

regards,

JF
