            django filters with pagination: showing same page after pressing next url

            You made an error in the URL of the button, the key-value pairs in the query string [wiki] are separated by an ampersand (&), not an ampersand with question mark (&?). By writing it that way, Django will interpret this as:



            Very slow framerate with AVFoundation and Metal in MacOS
            Asked 2019-Dec-18 at 01:39

            I'm trying to adapt Apple's AVCamFilter sample to MacOS. The filtering appears to work, but rendering the processed image through Metal gives me a framerate of several seconds per frame. I've tried different approaches, but have been stuck for a long time.

            This is the project AVCamFilterMacOS - Can anyone with better knowledge of AVFoundation with Metal tell me what's wrong? I've been reading the documentation and practicing getting the unprocessed image to display, as well as rendering other things like models to the metal view but I can't seem to get the processed CMSampleBuffer to render at a reasonable framerate.

            Even if I skip the renderer and send the videoPixelBuffer to the metal view directly, the view's performance is pretty jittery.

            Here is some of the relevant rendering code I'm using in the controller:



            Answered 2019-Dec-18 at 01:39

            Capture device delegates don't own the sample buffers they receive in their callbacks, so it's incumbent on the receiver to make sure they're retained for as long as their contents are needed. This project doesn't currently ensure that.

            Rather, by calling CMSampleBufferGetImageBuffer and wrapping the resulting pixel buffer in a texture, the view controller is allowing the sample buffer to be released, meaning that future operations on its corresponding pixel buffer are undefined.

            One way to ensure the sample buffer lives long enough to be processed is to add a private member to the camera view controller class that retains the most-recently received sample buffer:



            Use gstreamer to record audio on android(with Qt5)
            Asked 2019-Aug-18 at 13:28

            Trying to record audio on android with gstreamer(enable permission of audio record already), I prefer gstreamer but not the java api because there are more functions need to be added in the future, like convert the audio to specific format(S16LE, channels=1, rate=16000 etc), encode as wav, separate video/audio and so on

            uwp app AdvancedQuerySyntax for video file types
            Asked 2018-Oct-03 at 22:21

            in my uwp app I am getting video files from KnownFolder.VideoLibrary and I am using QueryOptions to get them, so taking advantage of that I am trying to use AdvancedQuerySyntax so that I only get video files, but I am actually getting subtitle files like srt as well. what am I doing wrong here? is the AQS syntax I wrote wrong? I think subs files are also considered as video files according to this syntax, is there a way I can narrow it down to getting only video files excluding subtitle files? or can I get a link to docs where I can know what is the list of extension types, this syntax actually will return? So I can manage it accordingly?




            Answered 2018-Oct-03 at 22:21

            Short answer: .srt and other subtitle files are classified as video files since any app supporting playback might want access to srt files.

            You can add an application search filter ext:<>.srt to remove srt files from your results.

            Long Answer: The inevitable question is why not have another type for Kind:Subtitles or something? Why include them for with Kind:Video?

            Well there is another pressure that goes on the Kind mappings beyond just "does this extension make sense as a video"? It all comes back to the SD card access on Windows Phone.

            See for Windows 8 an modern app accessing the SD card had to declare a file launch experience for any file type they wanted to see on the SD card. For example that meant that a video app would need a file launch experience for mp4, avi, ect. However, on Windows Phone this wouldn't work because there was no way for an app to override the default system app for mp4 or avi (there is another story here for another day). So we needed another way to give apps access to mp4 files on the SD card.

            The solution was that since the UI already said "Grant this app access to Videos and your SD card" then any app with both the video library capability and SD card access should have access to all files of Kind.Video on your SD card. Thus Kind.Video not only meant "Video files" but also "Files a video app would want access to".

            With this slightly changed definition, it meant that any files the built in video player needed were suddenly included in the Kinds.Video mapping. Which is where .srt files come from in the mapping.

            And as one of the people responsible for making the kind mapping decisions, I'd like to take this opportunity to apologize my mess and promise I'm not nearly as brain dead as you'd think looking at this design. Probably



            How to fetch both live video frame and timestamp from ffmpeg to python on Windows
            Asked 2018-May-08 at 13:52

            Searching for an alternative as OpenCV would not provide timestamps for live camera stream (on Windows), which are required in my computer vision algorithm, I found ffmpeg and this excellent article The solution uses ffmpeg, accessing its standard output (stdout) stream. I extended it to read the standard error (stderr) stream as well.

            Working up the python code on windows, while I received the video frames from ffmpeg stdout, but the stderr freezes after delivering the showinfo videofilter details (timestamp) for first frame.

            I recollected seeing on ffmpeg forum somewhere that the video filters like showinfo are bypassed when redirected. Is this why the following code does not work as expected?

            Expected: It should write video frames to disk as well as print timestamp details.
            Actual: It writes video files but does not get the timestamp (showinfo) details.

            Here's the code I tried:
