[vlc-devel] video problem to play on android phone

[kodmw-vlc at yahoo.com.cn]

Hi, all,

I tried to build a streaming server to receive multimedia data from **.m3u8 on the network and then stream it out with rtsp.
The browser on android phone played with video and audio if I did it with VLC.
But the browser played with only audio and no video (black screen) if I did it with demo code of libvlc from wiki.
I don't know the difference between the two mode.
Demo code is as follows:
=========================================
// vlc2stream.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include <conio.h>
#include <vlc/vlc.h>
#include <Windows.h>
int _tmain(int argc, _TCHAR* argv[])
{
     libvlc_instance_t * inst;
     libvlc_media_player_t *mp;
     libvlc_media_t *m;
     libvlc_log_t *log;
 
     /* Load the VLC engine */
     inst = libvlc_new (0, NULL);
 
     // logging
     log = libvlc_log_open (inst);    
     libvlc_set_log_verbosity (inst, 2);
     unsigned int level = libvlc_get_log_verbosity (inst);
     printf ("vlc log verbosity level = %d\n", level); 
 
    /* Create a new item */
     m = libvlc_media_new_path (inst, "http://192.168.1.186:1000/601.m3u8");
     // media option
     const char *options[]=
     {
        ":sout=#transcode{acodec=mp4a,ab=32,channels=2,samplerate=44100,vcodec=h264,vb=350,fps=15,scale=1}",
        ":sout=#standard{mux=mp4}",
        ":sout=#duplicate{dst=rtp{sdp=rtsp://:8554/601},dst=display}",
        ":sout-keep"
     };

     for (int i = 0; i < sizeof(options) / sizeof(options[0]); i++)
         libvlc_media_add_option (m, options[i]);
 
     /* Create a media player playing environement */
     mp = libvlc_media_player_new_from_media (m);
 
     /* No need to keep the media now */
     libvlc_media_release (m);
 
 #if 0
     /* This is a non working code that show how to hooks into a window,
         * if we have a window around */
         libvlc_media_player_set_xdrawable (mp, xdrawable);
     /* or on windows */
     libvlc_media_player_set_hwnd (mp, hwnd);
     /* or on mac os */
     libvlc_media_player_set_nsobject (mp, view);
 #endif
 
     /* play the media_player */
     libvlc_media_player_play (mp);
 
     while (!kbhit())
         Sleep (100); /* Let it play a bit */
 
     /* Stop playing */
     libvlc_media_player_stop (mp);
 
     /* Free the media_player */
     libvlc_media_player_release (mp);     
 
     libvlc_release (inst);
 
 
     printf ("message in log = %d\n", libvlc_log_count (log));
     system("pause");

    return 0;
}

=========================================
I think problem comes from the variable options[] in the code which is based on the demo, the document to vlc command and 

vlc software. Streaming with vlc software will generate a stream output string on the dialog "option setup".
I tried a lot of command in the options[] but no result.
Anyone can help me?

Thanks in advance.
