QNEDLEEQ: tak muzes si rikat jaka si stara vykopavka a utesovat se ze bys to nezvlad, ale ono to fakt neni tak komplikovane a navic ti to da i odkazy, kdyz si o to reknes. viz treba muj pokus, pricemz na webu chatgpt to je spravne zformatovane a kazde VLChelp je doopravdy odkaz primo do dokumentace kde to je napsane. Pokud to nefunguje, tak to minimalne usetri hledani spravneho mista v manualu:

Here’s how you can make a VLC playlist that defines play-times (start/stop) for each video, plus where the VLC documentation / community sources describe this.

🔧 How to make a VLC playlist with defined playtime per item

You can use an M3U playlist with VLC-specific extension tags, or an XSPF file. Here are examples.

Example using .m3u + VLC extensions
#EXTM3U

#EXTINF:3600,Video1 clip (from 0 to 120 sec only)
#EXTVLCOPT:start-time=0
#EXTVLCOPT:stop-time=120
/path/to/video1.mp4

#EXTINF:500,Video2 clip (from 30 to 200 sec)
/path/to/video2.mp4
#EXTVLCOPT:start-time=30
#EXTVLCOPT:stop-time=200

#EXTINF:0,Video3 whole
/path/to/video3.mp4


#EXTINF: is the standard tag that gives VLC (and other players) the full duration metadata; VLC uses it for display and ordering.

#EXTVLCOPT:start-time= and #EXTVLCOPT:stop-time= are VLC-specific options in m3u that tell VLC to start and stop each file at given times (in seconds).

Example using .xspf file


My Custom Playlist



file:///path/to/video1.mp4
3600000

0
start-time=0
stop-time=120




file:///path/to/video2.mp4
500000

1
start-time=30
stop-time=200







In XSPF, is given (often in milliseconds), though VLC may still show full durations rather than adjusted ones for some views.

The entries allow including VLC’s start/stop times.

⚠️ Limitations / Behavior

Sometimes VLC doesn’t update the "Duration" column in its playlist view to match your start-stop span; it might still show full video length. E.g. there’s a known issue: using #EXTVLCOPT:start-time/stop-time in .m3u playlists, the UI may still display the full duration for that item.

Also, not all VLC builds/platforms support every VLC-option tag in playlists, especially Android versions etc.

📚 Where in documentation / community sources it is written

Here are relevant sources:

VLC Help (“How to Play Certain Sections and Part of Video and Audio in VLC”) — explains using #EXTVLCOPT:start-time= and #EXTVLCOPT:stop-time= inside an .m3u playlist.
VLC Help

Community Q&A/Forums:

“Does VLC support a playlist format where one can specify start- and end-times?” — this confirms the #EXTVLCOPT:start-time and stop-time tags are what people use.
Reddit

The issue “Playlists with #EXTVLCOPT:start/stop-time don’t show duration correctly” — discusses the mismatch between displayed duration vs actual clip length in playlist view.
GitLab

The VLC wiki / help pages about Playlist formats and Saving playlists to file (M3U, XSPF, etc.) also discuss that VLC can export playlists and what formats are supported.

If you want, I can pull up the official Videolan wiki page (if still live) that defines the full set of vlc:option tags (like start-time, stop-time, etc.), so you have the authoritative spec. Do you want that?

QNEDLEEQ:
To specify play lengths for items in a VLC playlist, you must create a special M3U playlist file using a plain text editor, adding lines like
above each video file path. You can also achieve a similar effect by using the --run-time command-line option when starting VLC, which will play each item for a set duration.
