search for: seekpoints

Hello, metaflac provides exporting CUEpoints, but not SEEKpoints. As i understand, cuepoints represent gaps beetween tracks (inserting pause), whereas seekpoints merely describe a list of seekable points. Can cuepoint be used just as seekpoints (in the end, the only thing which matters is that some classic media players will recognize them). In the script i hav...

..., but some of the details in the history file puzzle me, so I've not tried to use it yet. Pardon my denseness here ... First, as long as you don't use the --cuesheet option when you encode, are .flac files encoded by 1.1.0 still readable by earlier versions? Second, if the old default for seekpoints was -S100x and the new one is -S10s, does that mean that, if you encode a 44.1-ksps WAV that was ripped from a CD, the old default was to set 441 seekpoints per second and the new one is to set one seekpoint every ten seconds? One of the major reasons I preferred FLAC to APE, despite APE's usu...

Hello, I managed to insert cuepoints from a cue sheet and check them with metaflac. I witnessed that the FLAC headers then had additionnals sections (one for cuepoints and one for seekpoints), but i could not find documentation how the format used to store them (frame counts for both ?). Anyway it seems that cuepoints must be specified in MM:SS:fr format. It would be nice if those could be specified also as frame counts (this alternate format is allowed for seekpoints): --seekpoint={...

...ting to the very last frame. Total samples should be that seekpoint + frame length To indicate that the last seekpoint is pointing to the last frame, there should be two placeholders: First has the offset set to ASCII "TOTALSMP", the next one all zeros. That some encoder adds placeholder seekpoints with that pattern just by chance is almost 0. When the decoder scans the seekpoints, the total_samples is 0 and if it detects that two placeholders it will set total_samples to that value. I don't see an issue with that? Old files are treated by new decoder just like before, new files are tre...

Thank you all very much for making things clear. I had confused seekpoints and cuepoints indeed !

...ingle FLAC file, there is a strong need for seeking ! It is common, typically in classical music, to have up to 40 tracks on a single CD (exemple: sets of variations, etudes ...) and it is much more handy to join them into a single FLAC, instead of having tens of mini FLAC files. But then you need seekpoints. So the questions still holds: 1. how can i check if the seekpoints i specified when encoding are actually there ? 2. what media players are aware of FLAC seekpoints ? Phil

Hello, I have used --import-cuesheet-from= to insert the cue points, which are OK according to "--export-cuesheet-to=-". The points I invoke are: - the possibility to specify them as frame count instead of time - the doc: i would not find in which format cue/seekpoints are stored in the headers - titles: apparently they get lost with this option. I guess they would be preserved if put into tags, but it seems odd to me to put a raw cuesheet into a tag Phil ----- Mail d'origine ----- De: Harry Sack <tranzedude at gmail.com> ?: porte64 at free.fr Cc: fla...

...ave something working, but what's the option/syntax for this ? As there is no --cuepoint option, i presume that absolute frame numbers must be specified within cuesheet files instead of HH:MM:FR as in the following extract ? Or do i have to specify something so that FLAC creates cuepoints from seekpoints ? TRACK 01 AUDIO INDEX 01 0 TRACK 02 AUDIO INDEX 01 12345678 TRACK 03 AUDIO INDEX 01 87654321 Phil

Hi List, Is there a way to correctly use the replay-gain feature on flac files that contain an entire album (i.e., multiple tracks with seekpoints added from a cue sheet)? -- Chris

Hi Neil, I think you have a misunderstanding or two. What you want to do does not require "code." In fact, you might want to move your question from the FLAC-Dev list to the FLAC (User) list. I'm on both lists, so I did not realize that you were basically asking in the wrong place. No "coding" skills whatsoever are required to create seekpoint markers in a
