swscale/aarch64 : vscale optimization
13 août 2022, par Swinney, Jonathanswscale/aarch64 : vscale optimization
Use scalar times vector multiply accumlate instructions instead of
vector times vector to remove the need for replicating load instructions
which are slightly slower.On AWS c7g (Graviton 3, Neoverse V1) instances :
yuv2yuvX_8_0_512_accurate_neon : 1144.8 987.4
yuv2yuvX_16_0_512_accurate_neon : 2080.5 1869.4Signed-off-by : Jonathan Swinney <jswinney@amazon.com>

Is there any library in python or can we use FFMPEG to detect the appearance of the lines pattern in video that is shown in the image attached below ? [closed]
21 septembre 2022, par Shreyas R

Hi All,


I am trying to find a way to detect the appearance of this lines pattern embedded in the link below.
If I get any match of this pattern in a video, I need to record that particular timestamp of the video where I got the pattern match.


My idea is to take the image and compare it against the video to find for approximate match percentage. If I get it, then I record that particular timestamp within a .txt file.


Is there any better way to achieve this ?
I think we can use Python or FFMPEG video filters to get a solution for this.


It would really help if anyone can support with a solution. Thanks


Update :
I got a reference where they have proposed a solution similar to my concern.


https://aws.amazon.com/blogs/media/metfc-automatically-compare-two-videos-to-find-common-content/


So we can try to achieve some output from this solution.

librosa can't load wav file in aws lambda docker
30 novembre 2022, par Luka SavicI have an AWS Lambda function created using Docker.
I have librosa installed, ffmpeg installed using the solution from this question : install ffmpeg on amazon ecr linux python


I checked in a Lambda function with
os.system("ffmpeg -version")and I managed to get valid output, stating different versions and parts of ffmpeg.

Problem is that when I do
librosa.load(wav_file)it gives the following error :

/your/path/.venv/lib/python3.9/site-packages/librosa/util/decorators.py:88: UserWarning: PySoundFile failed. Trying audioread instead.
 return f(*args, **kwargs) 


From what I've read, librosa should natively support .wav files, even without ffmpeg, and even though I have ffmpeg installed, it doesn't work.


One more information, .wav file was downloaded, player, and loaded with librosa on my local PC without any problems. I tried also on different wav and mp3 files, and the problems were still there.
