How to use the hardware acceleration for ffmepg on m1-max ?
10 février 2023, par ThoughtfulHackingSince there aren't m1 builds available from ffmpeg.org, I had to compile my own. Obviously, I'd like to get the best possible performance.


- 

- Does ffmpeg use the "Hardware-accelerated H.264" on the m1 max ?
- Is there anything I need to do, like compiler flags, to get it ?
- Any switch at run time ?
- How can I verify that it's being used ?










To compile ffmpeg, I just did the basics :


./configure --prefix=/tmp/ff --enable-gpl --enable-nonfree --enable-libx264
make
make install



For x264, I just did
./configure —prefix=/tmp/ff
make
make install


to run :


ffmpeg -i random.wmv -c:v libx264 -preset ultrafast -c:a aac output-ultra.mp4 



Anything else I should be doing ?

FFMPEG documentation example for chromakey doesn't work for green background png file
15 septembre 2021, par JPMIm new in FFMPEG and I try to make just simple green background chroma keying of png images.
In FFMPEG documentation in 38.16 Chromakey - there is an example script :



ffmpeg -i input.png -vf chromakey=green out.png



for which is said that "Make every green pixel in the input image transparent"
That exactly what i wanted.
I tried with many different png images but the result is always a copy of input image.
Also i replaced the word "green" to 0x00FF00 or 0x008000 and still no successes. Only when replacing green to black and then the result is as expected - transparent.
Im working on Windows with pre-build binaries of FFMpeg.
What am I missing ?
Thanks.

Is there a way to program the (Download) button to save a group of images as a one video ?
9 février 2024, par Lina Al-fawzanThis is my entire code. Its function is that everything the user writes or says will have images returned to him according to what he wrote/said, and the next image will be shown to him after he presses “close,” and he can save each image separately. I want to make a simple modification to it. First, instead of a close button, I want each image to be displayed for 3 seconds and the next one to be displayed, and so on... “all of them in one window”, and for the “download” button to be when the last image is displayed, and for them all to be saved in one video.
