JVLC can not play all videos like VLC can...

[odd_ferret]

Hi All,

I am using the latest download of JVLC and when I use it there are videos that work fine with VLC and seem to enounter EOF at the very beginning instead of playing the file. Seems like 50% of videos do not work using JVLC but do using vlc. Is there perhaps some options set in vlc that initializes the libraries this is missing from the VLCEXample.java file?

The messages I get using -vvv option for a failed video are:

More info,

Seems the mov files that failed via http from jvlc work fine from the disk. Also, does not matter if I use MediaPlayer or MediaListPlayer I get the same response.

Hi All,

I copied a mov file I was having problems with to my own site and it worked just fine via jvlc. More testing indicated asx files do not work from jvlc and all the mov files failed when going to a specific site.

Your problem is similar to the one described on the forum at viewtopic.php?f=32&t=54259

playlists (.asx, .m3u, dir://, ... ) are never automatically played when libvlc API is used (JVLC is based on libvlc API if I am not mistaken)

If it were in C/C++ with libvlc, (I suppose JVLC is not too different), things would be :

- If you play a playlist with media_player, libvlc_media_subitems() allows retrieving each items from the playlist once the playlist is demuxed.

- if you use media_list_player, you're doomed (this is an unfinished work)...

Hi erwan10,

I just read an very interesting email on the vlc dev group list where someone who developed MyUniPortal figured out what is going on.
He found out that the deprecated playlist object does something the mediaplayer and other new objects fail to do and that is take an asx, mov refernce and get the metadata from it in order to run it. For example an asx might contain mms:xxxx:9089 and if you pass that to the MediaPlayer or MediaListPlayer it will play the video correctly. Seems vlc.exe is getting that info correctly and the playlist object is also getting it correctly but not the rest of the jvlc api.
Also noticed was the incomplete nature of the MediaListPlayer object and in one case the MediaPlayer object does not have a isPlaying method. MediaListPlayer is missing several important methods such as getPosition and setPosition which you need for a progress bar.

These issues may be the result of an evolving interface of vlc itself and not the JVLC api. Hopefully the JVLC/VLC team can address the one issue for metadata to get the real url and at least the MediaPlayer object will be usable. So far no response from the JVLC developers so hopefully they understand the issue and address it.

The JVLC team has put a great deal of effort into the api and seems like just a little more is needed for others to use it

Just one thing, media_player is usable right now even with asx files.

Media_player is designed so that playing a playlist (asx, m3u; dir://) means parsing it and populating a subitem(media_list) (even if the playlist is limited to one item). It is then up to the developer to __explicitly__ select an item to be played from this media_list.

The deprecated playlist was designed differently (parsing a playlist and starting first item was done in one call by default). Media_player just does things differently.

Media_list_player (which is automating playback of successive items) is another matter. And for this one, libvlc developers have some more work to carry out.
