VLCKit "lengthWait" not returning a value
Posted: 18 Jul 2020 16:23
Hello,
I am trying to use VLCKit / TVVLCKit on an iOS/tvOS project.
I would like to be able to scan through a list of VLCMedia items and identify the length (duration) of the video file ahead of time, prior to playing the videos.
I am first ensuring each item is parsed with the following:
but even after parsing has completed and the delegate method has been called, logging or does not seem to work- Im just seeing a length string of "--:--"
However, if I take a VLCMedia item, play it, and then check the length, I then see the correct duration. This works:
However, the time delay in the asyncAfter call does matter- I also tried 0.1 seconds, and that resulted in no value- just "--:--"
I've also attempted using lengthWait prior to playing the file like so:
This is not working for me either.
Ultimately my question is:
I'd like to know if there are any other strategies to identifying a VLCMedia item's length/duration without actually playing the file. It seems the length info is only available after loading the file to play, calling or do not seem to work for me. The files I am using are on the local network and are made available via SMB1.
If I need to "queue" up the item to play it, without actually playing it, to get the length info, I could potentially work with that. I only need to do this once when adding a file to my app's "library" and I can store the value. It seems like "media.lengthWait(until:" should be what I need, but even adding a very long wait time doesn't seem to produce a result for me.
Please let me know if there are any other strategies to get a media item's length value without actually playing it. I'd really appreciate it!
Thank you.
