QUESTION
I am writing a program in C language using gtk3 library. I want it to be able to receive a h264 video stream from a certain IP address (localhost) and UDP/RTP PORT (5000).
In order to do it, I am using gstreamer to both stream and receive the video.
I managed to stream the video using the following pipeline :
send.sh :
gst-launch-1.0 filesrc location=sample-mp4-file.mp4 ! decodebin ! x264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! rtph264p
I managed to display the video in a new window using the following pipeline :
receive.sh :
gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp,encoding-name=H264" ! rtph264depay ! decodebin ! videoconvert ! autovideosink
At this point, everything works fine. But now I want to receive the stream and display it inside my C/GTK program. I am using the following code (found on internet and adapted to make it compile) :

Changin xvimagesink by ximagesink :
sink = gst_element_factory_make ("xvimagesink", NULL); g_assert(sink);
becomes
sink = gst_element_factory_make ("ximagesink", NULL); g_assert(sink);
Hope it will help some of you facing the same problem.
QUESTION
I did some research and found this: Setting a fixed FPS in Pygame, Python 3 and this: pygame clock.tick() vs framerate in game main loop. It is similar to what I am asking.
So the clock.tick(FPS)
caps the program to run at that FPS
. The reason you do this is so you can control the FPS
of the program and it makes it easier for time stuff like waits.
But how can I unlimited FPS
and still control my FPS
for time stuff like waits? From my understanding, this is not possible, due to the fact that clock.tick(FPS)
caps the FPS
and while not adding it in means unlimited FPS
but you not being able to control the FPS
.
So it seems to be a question of weather to cap you FPS
for control or have your program run as fast as possible, but without control.
In conclusion, what I am asking is four questions;
- Pros and cons of capping your
FPS
- Pros and cons of not capping your
FPS
and going on with the naturalFPS
of your program - Is it possible to have unlimited
FPS
and still control myFPS
for time stuff like waits? - If so, how?
ANSWER
Answered 2021-Jun-14 at 21:42You have to calculate the movement per frame depending on the frame rate.
pygame.time.Clock.tick
returns the number of milliseconds since the last call. When you call it in the application loop, this is the number of milliseconds that have passed since the last frame.
When you call it without a parameter (framerate=0
), the FPS are unlimited.
Define the distance in pixels that the player should move per second (move_per_second
). Then compute the distance per frame in the application loop:

QUESTION
My GUI is able to play videos automatically when selected in the QListWidget
. However, instead of normal speed, the videos play very fast. I use 720p Mp4 videos as examples and are placed in a certain folder. I tried using cv2.CAP_PROP_FPS
and cv2.CAP_PROP_BUFFERSIZE
, but they are both not working. I am using pyqtSignal
in the QThread
and the convert_cv_qt
function which I saw in other guides. How do I play the videos in normal speed / frame rate?
ANSWER
Answered 2021-Jun-14 at 10:44When you use VideoCapture with a file if you call "cap.read()" you will obtain the next frame on the video, regardless of its actual framerate. Hence, you should use a "msleep" every time you capture a frame:

I'm getting an error (shown below) when I run my program. Does anybody know how to solve it?
...ANSWER
Answered 2021-Jun-13 at 21:34Uninstall the others as before:
pip3 uninstall opencv-python
pip3 uninstall opencv-contrib-python
pip3 uninstall opencv-contrib-python-headless
And then only install the first two:
pip3 install opencv-python==4.4.0.46
pip3 install opencv-contrib-python==4.4.0.46

QUESTION
This was a problem on Pramp. The question:
The awards committee of your alma mater (i.e. your college/university) asked for your assistance with a budget allocation problem they’re facing. Originally, the committee planned to give N research grants this year. However, due to spending cutbacks, the budget was reduced to newBudget dollars and now they need to reallocate the grants. The committee made a decision that they’d like to impact as few grant recipients as possible by applying a maximum cap on all grants. Every grant initially planned to be higher than cap will now be exactly cap dollars. Grants less or equal to cap, obviously, won’t be impacted.
Given an array grantsArray of the original grants and the reduced budget newBudget, write a function findGrantsCap that finds in the most efficient manner a cap such that the least number of recipients is impacted and that the new budget constraint is met (i.e. sum of the N reallocated grants equals to newBudget).
Analyze the time and space complexities of your solution.
This is what my solution looks like, in PHP.
...ANSWER
Answered 2021-Jun-13 at 19:39You should try and reduce the repetition of calculations, so the maximum budget can be worked out before the foreach
loop. Also rather than have an if
to check if it's above this value, then use min
to take the lowest of the entry and the maximum budget

I'm wondering how to change font and color specifically for figure captions in Rmarkdown for a PDF output. I know how to do this for word output (creating a separate document), but often figures are submitted to journals as PDFs.
Note that this is not whether you can change the color of text in a PDF which is answered here: Changing the font size of figure captions in RMarkdown pdf output. If I try this within the fig.cap = "fig text here.\\label{...}"

In your CMD prompt run these three commands and then try to run your program again.
pip3 install opencv-python==4.4.0.46
pip3 install opencv-contrib-python==4.4.0.46
pip3 install opencv-contrib-python-headless==4.4.0.46
The version specifics may not be necessary but it's what worked last for me.
