I see, so you replace the default media_player in media_list_player with one that can be controlled by the usual media_player_* controls.

Oops, you are right. I checked the file labeled .mp4 but it was actually mpeg, according to ffmpeg. A file that is truly mp4 does seems to be accurate about start-time, while the mpeg one is wrong. This is with the new vlc 2.0 The old vlc 0.8.6i was accurate for both files (though its video was corr...

libvlc_media_player allows changing the mute, fullscreen, rate kinds of things. Does libvlc_media_list_player have similar controls?

> vlc myfile.mp4 --start-time=10
Also very far off. But the same command run with an old (0.8.6i) vlc worked correctly.

I see libvlc_media_list_player_pause I can' tseem to find a libvlc_media_list_player_set_pause or un_pause. How can I un pause a playlist?

>> In you experience, what are the most precise-seeking file formats?
>mkv or mp4, probably.
The file I was trying, that went to :36 instead of :44, was an mp4. So it sounds like some experimentation is needed.

I start playing, wait 2 seconds, then use libvlc_media_player_set_time(44000) to go to the 44 second point. A call on libvlc_media_player_get_time returns 44000. Then I wait another two seconds and call libvlc_media_player_get_time and it returns 36368, which appears to match the actual time of the ...

> No, there is not.
Why? No volunteers to make it? Or a policy decision to break decisively with the past?

> This documentation does not match LibVLC 1.0 or older. Is there a document listing the changes needed to code that uses the old (0.8.6f in my case) LibVLC? Or better yet, a version 0.8xxx style wrapper for LibVLC 2.0 I have an old program that works, but would like to take advantage of the bug fix...

Thanks. I'll see about rewriting my libvlc wrapper code.

>no, it is not. Is there a description somewhere of the changes, for those of us who developed programs around the "ancient" libvlc? Or is it so different we should forget we ever heard of the old one, and start over from the ground up with the new one? Also, if the latter, whta's the life...

>use libvlc 1.1
a) will that solve the problem?
b) is 1.1 upward compatible with 0.8.6x? I can't seem to find any "changes" list.

I have two old programs running on a dual-core machine. One just runs music playlists (--no-video) and the other I use for video-only video clips. All is fine for 720x480 video, but for a 1440x1080 video clip the sound goes silent and stays silent for some time after that video is done - even throug...

Every once in a while I get a VTS_01_1.VOB that vlc won't play. "debug" verbosity says the file doesn't look like an MPEG PS file. Sure 'nuff, there's an extra 0xA0000 bytes of stuff before the pack header and system header, and the first 11 bytes in the file spell "DVDVIDEO_TS"....

Some files play low on the screen in full screen mode. There's lots of black at the top and the bottom of the image is cut off. If I change the advanced video preferences from Center to Top, the problem goes away. It seems odd that "Center" doesn't mean "center vertically". Also,...

> Could you give us the messages with verbosity set to 2 (High) of the transitions ?
So did that allow you to figure out the cause of the problem?

It's not clear to me where to send the log files so I put them on my web site The show with fast transition, using pcm_s16be, generated log file http://home.comcast.net/~tommoran4/log_never.txt rrd output http://home.comcast.net/~tommoran4/rlog_never.txt The show with a slow transition, that uses ac...

>Could you give us the messages with verbosity set to 2 (High) of the transitions ? I tried vlc --verbose 2 --logfile vlclog playlist.m3u and let it play all the way through. But there is no "vlclog" on my machine and in fact no new file of any name in either the vlc directory or the direc...

I'm sorry this isn't clear. Playlist_A lists "program_a\VTS_01_1.VOB" on the first line and "program_a\VTS_01_2.VOB" on the second line. When VLC plays Playlist_A there is a barely noticeable transition when it finishes _1 and starts _2 Playlist_B lists "program_b\VTS_01_1.V...

For one of the shows the transition between _1 and _2 is fast. The only difference ffmpeg -i shows between _1 and _2 is the swapping fof which stream is audio and which is video. For the other show the _1 to _2 transition is slow. Again, the only apparent difference is the order of audio/video strea...

According to ffmpeg -i the only difference (other than length) between VTS_01_1.VOB and VTS_01_2.VOB is that the first has audio in stream 0.0, video in stream 0.1, and the second has the reverse. But that's true for both the quick-transition and the slow-transition shows. The only difference I see ...

I have two half hour shows, each has a 1GB (about) VTS_01_1.VOB and about a .5GB VTS_01_2.VOB, and a playlist.m3u that simply lists VTS_01_1.VOB followed by VTS_01_2.VOB When planing one of the playlists there's an almost imperceptible glitch at the point of transition from _1.VOB to _2.VOB. When pl...

Trying to play a .vob whose audio is (according to ffmpeg) pc_s16be, the video is fine but the audio is just static. Is this supposed to work? Does it need some special handling? I tried vlc 8.6d under Windows Vista, then 8.6f under W2k, same behavior.

Is there any libvlc call to let me skip to a point near (say, 1 minute before) the end of a vob file? VLC_PositionSet and VLC_TimeSet go to the wrong places (even VLC_LengthGet says a 10:45 files is 7:55 long). I want to search for the actual end (ie, skipping and black trailer).

Sometimes the value of start-time is roughly tripled, eg "start-time 3" starts 10 seconds in, and on other video files it's total nonsense, ie, 0 goes to the start, 1 goes several minutes in , 2 is somewhere else entirely, etc. What's going on? Is there a reliable way to start playing a ce...
