libvlc_media_player_get_time return 0 when play rtsp stream

[Jeremiah]

libvlc_media_player_get_time and libvlc_media_player_get_position return 0 when playing rtsp stream using vlc-0.9.9a.

and/so the slide isn't moving.....

but use vlc-0.8.6i, all is good! the slide is moving and i can get the real time from libvlc_media_player_get_time.

so what's the matter?

by the way, when i testing the vlc-1.0.0-rc1, it cannot play rtsp stream successfully. i complie it using contrib-20090219-win32-bin-gcc-4.2.1-sjlj-runtime-3.13-only.tar.bz2 in cygwin.

so what's the matter?

There was huge RTSP recode between 0.8.x -> 0.9.x so I assume this is because of it

it cannot play rtsp stream successfully

Could you paste VLC message log with RC2 or RC3?

thank you very much, vlc_help. you're a very good guy.

i compile for myself using cygwin and contrib-20090118-win32-bin-gcc-4.2.1-sjlj-runtime-3.13-only.tar.bz2.
and i use vlm of vlc-0.9.9a.zip as the vod server. i can play rtsp://127.0.0.1/test1 using other version of vlc expect vlc-1.0.0-rc*.

here is the log:

i don't use the exe file the the videolan gived. so maybe i'll try the official file.
-------------------------------------------------------------------------------------------------
i tried the official exe file. it works fine with rtsp, but the slide dose not move, and the current time of the video is always 0.00. so the libvlc_media_player_get_time of rc3 will return 0 for rtsp.

also maybe the compiling thing of my rc3 is wrong. the contrib maybe the point, i think.

so can jb~ give us the new contrib for vlc-1.0.0-rc*?

thank you all very much....

hi
i added some msg_Dbg in live555.cpp

1. under function Control

Code: Select all

switch( i_query ) { case DEMUX_GET_TIME: pi64 = (int64_t*)va_arg( args, int64_t * ); msg_Dbg(p_demux,"====p_sys->i_npt=%d====\n", p_sys->i_npt); if( p_sys->i_npt > 0 ) { *pi64 = p_sys->i_npt; return VLC_SUCCESS; } return VLC_EGENERIC;

2. under function StreamRead

Code: Select all

/* Retrieve NPT for this pts */ tk->i_npt = (int64_t) INT64_C(1000000) * tk->sub->getNormalPlayTime(pts); msg_Dbg(p_demux,"^^^^tk->i_npt=%d^^^^\n", tk->i_npt);

and the log shows:

Code: Select all

[00000398] live555 demux debug: ====p_sys->i_npt=0==== [00000398] live555 demux debug: ^^^^tk->i_npt=0^^^^ [00000398] live555 demux debug: ^^^^tk->i_npt=0^^^^ [00000398] live555 demux debug: ^^^^tk->i_npt=0^^^^ [00000398] live555 demux debug: ^^^^tk->i_npt=0^^^^ [00000398] live555 demux debug: ^^^^tk->i_npt=0^^^^

it meas : tk->i_npt = (int64_t) INT64_C(1000000) * tk->sub->getNormalPlayTime(pts); always return 0;

what's the matter????

[VLC_help]

Shouldn't you print long ints with %z ?

[Jeremiah]

it's the same using %lld to print long ints in this case, getNormalPlayTime(pts) always return 0.
this is weird....
