I don't want to show playback speed in my video, is there any controls or controlList properties to disable that option like controls disablepictureinpicture controlslist="nodownload"

I imported a tif movie into python which has the dimensions (150,512,512). I would like to calculate the mean pixel intensity for each of the 150 frames and then plot it over time. I could figure out how to calculate the mean intensity over the whole stack (see below), but I am struggling to calculate it for each frame individually.

I'm trying to add rotation metadata to the video recorded from RTSP stream. All works fine until I try to run recording with segment format. My command looks like this:

I have several videos on my site that have the same class.

I want to play only one video when hovering over it. As soon as I removed the hover, the video was paused with a delay of 1 second.

I learned how to start a video and pause it. But as soon as I add setTimeout I get an error: Uncaught TypeError: Cannot read properties of undefined (reading 'pause')

Below I am attaching the html code of my solution:

I have an interlaced video stream and need apply a filter (any filter that takes two frames as input , for example tblend or lut2) on custom video frames and place output of them between mainframes like this :

I would like to be able to robustly stop a video when the video arrives on some specified frames in order to do oral presentations based on videos made with Blender, Manim...

I'm aware of this question, but the problem is that the video does not stops exactly at the good frame. Sometimes it continues forward for one frame and when I force it to come back to the initial frame we see the video going backward, which is weird. Even worse, if the next frame is completely different (different background...) this will be very visible.

To illustrate my issues, I created a demo project here (just click "next" and see that when the video stops, sometimes it goes backward). The full code is here.

The important part of the code I'm using is:

In my Facebook Video Downloader android application i want to show video resolutions like SD, HD with size. Currently i am using InputStreamReader and Pattern.compile method to find SD and HD URL of video. This method rarely gets me HD link of videos and provides only SD URL which can be downloaded.

Below is my code of link parsing

So I have a page with a grid layout, with a header and a footer and a black content container in the middle.

I'm having regularly issue with hvc1 videos getting an inconsistent number of frames between ffprobe info and FFmpeg info, and I would like to know what could be the reason for this issue and how if it's possible to solve it without re-encoding the video.

I wrote the following sample script with a test video I have

I split the video into 5-sec segments and I get ffprobe giving the expected video length but FFmpeg gave 3 frames less than expected on every segment but the first one.

The issue is exactly the same if I split by 10 seconds or any split, I always lose 3 frames.

I noted that the first segment is always 3 frames smaller (on ffprobe) than the other ones and it's the only consistent one.

Here is an example script I wrote to test this issue :
