ng-select | : star : Native angular select component | Autocomplete library

Because this.vehicles is filled asyncronously, that's how .subscribe() works. When your ng-select is rendered, this.vehicles does not contains your api response.

A simple way to handle this :

Traditional videos need to have the following sets of metadata:

• The transfer function determines how you should map encoded RGB or YUV values into display luminance (-color_trc in ffmpeg options, transfer in x265 options). Common options are HLG (arib-std-b67) or PQ (smpte2084).
• The colorspace primaries define how encoded RGB values map into real colors (-color_primaries for ffmpeg, colorprim for x265). For HDR10 the most common option is bt2020.
• The color matrix is used to convert between RGB values (which are used to display data on the screen) and YUV values (which make the video encoders more efficient, because they roughly separate luma (Y) from chroma (UV) channels), and correspond to -colorspace in ffmpeg and colormatrix in x265. For HDR10 the most common option is bt2020nc.
• The signal range determines if RGB values between 0-100% are mapped to the full 0-255 (in 8-bit) or 0-1023 (in 10-bit) range, or if a margin is reserved for internal use (-color_range in ffmpeg, range in x265). It is traditionally "limited" (or: "tv", "narrow") in videos and "full" (or: "pc") in RGB images.

HDR10 defines additional metadata on top of that, which are intended to be used by the OS/player to tune the video output on non-HDR capable screens so that they can be displayed as best as they can under those constraints:

• MaxFALL and MaxCLL describe resp. the average and maximum luminance of the video (max-cll x265 option)
• Mastering display characteristics describe the "perfect" display the video is intended to be displayed on (master-display x265 option)

Now, a few things need some special care:

• Traditional metadata can be set in both the video container and the x265 stream (so they should be set in both ffmpeg and x265 so as to avoid mismatch when playing).
• Traditional metadata should be set for both the input (before -i) and output (after) formats, so that ffmpeg can do proper conversions when encoding.
• HDR10 metadata are only present in the x265 options; ffmpeg knows nothing about them and they don't affect the video pixel values.
• Unfortunately the default filter used by ffmpeg for format conversion (swscale, or -vf scale in the command-line) has a lot of issues when applied automatically. I found that it is best to always specify at least the signal range explicitly, or even use zscale which replaces it and is much better behaved. Several issues exist with swscale, so it is tricky to get right.
• YUV to/from RGB conversions (which is what we're doing here since we use RGB images as inputs!) are different between traditional SDR (BT709) videos and HDR10 (BT2020). This is a very common source of errors, because a lot of ffmpeg internals assume the default (potentially wrong) conversion if not explicitly specified in both input and output formats!
• The -pix_fmt for the input images should be determined automatically, but I included it here to be comprehensive ; it is also required if you want to stream from raw RGB data.
• The -pix_fmt for the output video specifies that we want to pass 10-bit YUV data to the encoder and is required.
• This command-line assumes your TIFF images already contain the correct color profile (they are already HDR10 Rec2020 HLG images). If you want to do conversions from e.g. sRGB or other spaces you need to set the specific formats for the input file and zscale filter properly.

Bearing that in mind, we can use the following command-line to convert Rec2020 HLG RGB images into an HDR10 Rec2020 HLG x265/HEVC video:

What you need to do is have your agents wait in the queue and then have a function to remove them from the queue and then send them to the correct service block. The best way to do this is with an enter block where you can send them to.

See example below

You then need to call this function at the On enter code for the queue as well as the On exit code for the service blocks, to ensure you are always sending new agents when there is space.

I just solve this issue by correcting the RxJS version to 7.4.0. I hope this can solve others issue as well.

Wrap it into a div and use ngIf to hide it in case the list has no items

This strange behaviour with the visible state of a "save queue" was only true in the interpreted code running in the shell, not in regular compiled modules. In the actual C implementation of receive, there is only one queue with a pointer to keep track of which ones have been scanned so far, and process_info does not show an empty queue during a real receive. The behaviour of the interpreted code was fixed back in R16B01, so nowadays there is no visible difference: https://github.com/erlang/otp/commit/acb8ef5d18cc3976bf580a8e6925cb5641acd401

Add a getter function that has computed behavior (only executed if there is an update)

For Angular 10, you can use version 1.10.5 of the Library.

This solution seems to work. You need formControl functionality in the ngOnInit function of the controller. Hope this helps.

In the html file, I have:
