According to the docs only three options are available (nodownload, nofullscreen, and noremoteplayback) and none seems to do what you want.
And you can't style the browser's default control set, but you can use the (JavaScript) Media API to build your own control set which of course you can style in any way that you like. See this CodePen.

Calculate average pixel intensity for each frame of tif movie

Asked 2022-Feb-18 at 23:25

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.

jQuery. Pause video with timeout

Asked 2022-Feb-04 at 20:36

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:

ANSWER

Answered 2022-Feb-04 at 20:36

The issue is because this in the setTimeout() function handler refers to that function, not to the element reference provided in the invocation of the outer hoverVideo() or hideVideo() functions.

To fix this issue create a variable in the outer scope to retain the reference to this which you use within the setTimeout():

FFmpeg : How to apply a filter on custom frames and place output of them between mainframes

Asked 2022-Feb-04 at 10:13

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 :

You may chain tblend, interleave and setpts filters, while the two inputs to interleave filter are the output of tblend and the original video:

Javascript: frame precise video stop

Asked 2022-Jan-28 at 14:55

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:

ANSWER

The video has frame rate of 25fps, and not 24fps:

After putting the correct value it works ok: demo
The VideoFrame api heavily relies on FPS provided by you. You can find FPS of your videos offline and send as metadata along with stop frames from server.

The site videoplayer.handmadeproductions.de uses window.requestAnimationFrame() to get the callback.

There is a new better alternative to requestAnimationFrame. The requestVideoFrameCallback(), allows us to do per-video-frame operations on video.
The same functionality, you domed in OP, can be achieved like this:

Found a solution for this so posting as answer.

This can be done by extracting Page Source of a webpage and then parsing that XML and fetching list of BASE URLs.

ANSWER

Answered 2022-Jan-21 at 00:57

1fr

The first thing you need to know is that 1fr is equivalent to minmax(auto, 1fr), meaning that the container won't be smaller than its content, by default.

So, start by replacing 1fr with minmax(0, 1fr). That will solve the overflow problem.

QUESTION

Inconsistent frame number with ffmpeg

Asked 2022-Jan-16 at 00:46

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 :

...

ANSWER

Answered 2022-Jan-11 at 22:08

The source of the differences is that FFprobe counts the discarded packets, and FFmpeg doesn't count the discarded packets as frames.

Your results are consistent with video stream that is created with 3 B-Frames (3 consecutive B-Frames for every P-Frame or I-Frame).

According to Wikipedia:

I‑frames are the least compressible but don't require other video frames to decode.
P‑frames can use data from previous frames to decompress and are more compressible than I‑frames.
B‑frames can use both previous and forward frames for data reference to get the highest amount of data compression.

When splitting a video with P-Frame and B-Frame into segments without re-encoding, the dependency chain breaks.

There are (almost) always frames that depends upon frames from the previous segment or the next segment.
The above frames are kept, but the matching packets are marked as "discarded" (marked with AV_PKT_FLAG_DISCARD flag).

For the purpose of working on the same dataset, we my build synthetic video (to be used as input).

Vulnerabilities

No vulnerabilities reported

Install smartLLSM

Install correct PyTorch version from here, for example:.
store_all - tallies the number of cells in each phase for each file, results stored in all_cells_found_{DATE}.csv within watch folder
set_thresh - saves ALL cells detected by YOLO of a certain class and saves images to a folder. images are named based on their YOLO confidence score. This allows users to visually determine a threhsold they would like to use for detecting cells/initiating imaging.
annotation_gui.py provides an efficient script for manually annotating cells. Users can set their own dictionary of keys to label cell phases (labels_dict). In addition, a binary classifier can be used to filter out tiles that do not include mitotic cells (nn_filter). This bootstraps the annotation process by only prompting users to label tiles that include rarer mitotic cells. Our trained binary classifier weights can be found here. Demo tiles that are ready for annotation can be found here. In order to generate tiles for annotation, tifs were first processed through Cellpose to segment out individual cells.
