1.2.0 cue file problem

[Schnuffel]

i found another small bug

with some cue files vlc jumps not to the start of a new track when its selected in the playlist
instead it jumps to the last 10 seconds of the previous track

this bug happens only with a few files

i though that the times in the cue file are wrong but foobar2k jumps to the correct start of the tracks
seems vlc still has some issues with reading cue files properly, but basic cue support works

[VLC_help]

With those problematic files, does

Code: Select all

vlc filename --start-time=123

start at correct position? If not, then the issue is not in cue file but in audio file.

[Schnuffel]

it makes no difference
with the the code from above

i tried vlc 1.1.11 and 2.1.0 git
same problem

these files were created with eac so there shoudn't be a problem
foobar2k has no probs with finding correct position of tracks


btw: seeking is a bit unconfortable too
when a track in the palylist is selected
the seek bar shows the complete flac file instead of only the selected track
this makes seeking inside a track nearly impossible because u will jump to another track easily

[VLC_help]

Currently VLC core doesn't support input splitting, so the CUE behavior most people would want to see isn't possible.

[Schnuffel]

would it be possible to add hyphen in the seek bar ?

for e.g. when u play a dvd with vlc 2.x u have these hyphen for each chapter on the seek bar
may be this would be possible for cue files too

have "chapter marks" for each track
this would make seeking a bit more comfortable



edit:

i just tested medieval cue splitter (the tool can create single tracks from a large flac/ape/wav... file)
the tool also has no problems with the cue files from above to find the correct track length

so there seems to be a bug in vlc ....

hmm vlc is jumping to the correct time
when u look at the time near the seek bar
its the right time for next track but its still to early
the complete flac length is shown correct

so i don't know why vlc cannot jump to the correct start
may be a bug in flac decoder

vlc is a great player but these small little bugs here and there drive me crazy




hmm to test if its flac causing the problem i will decode the flac to wav and see if the cue file works for the wav file correct or not..

[Schnuffel]

edit:

after converting the flac file to wav and editing the cue file from flac to wav
vlc can find the correct starting positions

now i converted the wav file back to flac (using offical flac command line version) and changed cue file back to flac

and its working !!!

(another small cue file problem i was able to solve *g* )


but the old flac file was not damaged or modified ( iam 100% sure of it)
seems vlc is using an outdated flac decoder which cannot handle some flac files properly !
may be the old flac file used a compression rate or setting which caused the problem with vlc....

when its time it would be good to check vlc codecs for latest flac decoder




here my little cue file summary:
(may be this should be included in a faq )

for vlc 2.x should work for 1.1.x too


problem:
after loading a cue file the track names are not shown correct in the playlist
and/or will be overwritten while changing the tracks in playlist

reason:
the big flac/ape/.. file contains an id tag
vlc don't know what to show in playlist if a cue file is used and when the flac file has an own id tag

solution:
use a tool like mp3tag (http://www.mp3tag.de/) and remove the id tag from the flac/ape/... file
(when using a cue file it is not necessary to use an own id tag for the big flac/ape/.. file)



problem:
when playing a flac file combined with a cue file vlc has problems to jump to
correct starting positions of the tracks when using playlist

reason:
may be a bug in flac file or flac decoder of vlc...

solution:
use official flac.exe (http://flac.sourceforge.net/) and decode flac file back to wav
then encode the wav file back to flac
and vlc should now find the correct starting positions

(flac and wav are both loseless formats so there is NO quality loss in doing this ! )






edit:
i found another small bug
when a track is finished vlc will immediately play next track for 1/2 second then stops
updating playlist to next track and starts playing the track from beginning

its nice that vlc will update the playlist and will show the correct track name of next song
but to avoid the little playback break vlc has to do the update of the playlist/file info window faster
or it has to update the window without stopping the playback

but this is only a minor bug
and i have a temp. solution for it
when u r planning to play the whole flac/ape/... file don't use the cue file instead open the flac/ape/.. file directly to avoid playback breaks between tracks

Bugs should be pushed with correct description and samples to trac.

[Schnuffel]

uploading the flac file will be nearly 600mb

the bug can be reproduced easily
just take any cue/flac file

[VLC_help]

It is most likely the flac compression level issue. There has been those earlier.

[Schnuffel]

okidoki

hmm any chance of updating the flac decoder ?

[VLC_help]

We are already using the latest official version (flac-1.2.1-src).

[Schnuffel]

hmm then there must be another problem
foobar2k has no probs with these flac files

decode them to wav and reencode them back to flac solves it
but this shouldn't be the final solution


at least vlc supports cue files
something that mpc (hc) and mplayer (smplayer) don't

[Schnuffel]

with 2.0 final the bug is still there

not a major bug but still a bit annoying
