Object.keys(object) return an array of property names of the provided object and in your case it will return [iconArraya,iconArrayb,iconArrayc] if want to do it this way you'll have reference the object i.e for each value in the array you need to do this object[value] by the way this is called bracket notation you can search it if you're unfamiliar it the same using a dot like object.value here's how ===

It is something between deflate, zlib and gzip. I don't know. But I can decode it now.

Just use zlib, with inflateInit2(&strm, -MAX_WBITS) instead of inflateInit(&strm).

Yes, it is totally good. But why did I think it broken? Because my archive manager don't decode this! Anyway, I need to call zlib by my own. I have suggested the archive manager developers add this feature - which is useful, no?

Problems with your command #2:

• Frame rate is too low. Most players are unable to play 1 fps. Use 10 fps or higher for output, or set input -framerate to 10 fps or higher.
• Chroma subsampling. Most players can only play 4:2:0, so use the format filter to force it to 4:2:0.
• MP3 in MP4. Some players are unable to play MP3 in MP4. For highest compatibility use AAC. ffmpeg will choose AAC by default for MP4.
• Faststart (optional). Add -movflags +faststart so MP4 can begin playback faster.

A FilteredList will update whenever it's Predicate changes or whenever it detects a change in the source ObservableList. The type of event you want to fire is an update event. This event signifies one or more elements have been updated (e.g. when a property changes). In order to do this you have to construct the ObservableList with the appropriate factory method: FXCollections.observableArrayList(Callback).

This factory method takes a Callback that accepts an element of the ObservableList and returns an Observable[]. The Observables in the array will be listened to for invalidation events and, when detected, will cause the ObservableList to fire an update change.

From looking at your code it seems¹ like the Model class has a status property. If you want to fire updates when the status changes you should use:

This error occurs because youtube-dl ignores URI parameters after ? for the filename, so the next file it tries to download has the same name with the previous one and it fails because a file already exists with that name. The solution is to use the --output template filesystem option to set a filename which it'll have an index in its name using the variable i.

1) no. flv.js plays flv files

2) hls.js plays m3u8 files.

• the interface you are using is the loopback one = only local packets. check IFACES.show() for the others. My guess would be that you're missing an installation step.

• the answer is never received

• you could add a timeout=... to sr()
