kandi X-RAY | OS-ARM Summary

OS-ARM is a C library typically used in Internet of Things (IoT), Raspberry Pi applications. OS-ARM has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

An open-sourced, low cost, high performance 3D printed 6-axis robotic arm. The main goals of this project are. This arm is not industrial and it will not be fast, but that is not my goal. But it will hopefully be a very nice looking arm fully capable of 6dof motion, cheap enough to keep it accessable but capable enough to actually do something (aka carry more than a 50g payload). This is not your typical RC servo arm. It's gonna be epic.

Using x86 libraries and OpenMP on macOS arm64 architecture

Asked 2021-May-06 at 12:31

I have a MacBook M1 and have installed a library on my machine that was compiled for an x86 / Intel architecture. I have some source code that uses OpenMP. I would like to compile my code and link my executable to the x86 library using a clang compiler.

I am able compile source code with no x86 dependencies by following the instructions here, using an implementation of clang that is distributed with brew.

However when I try to compile with the -arch x86_64 argument and link to the x86 library I find that clang tries to link my executable to an OpenMP library that is built for the arm64 architecture.

Is it possible to install a version of clang on a MacBook M1 where the OpenMP libraries are built for x86 architectures?

Here is an example of an error that I get using my current setup, even when not linking to an x86 library.

First of all, running x86 binaries on M1 ARM processors is possible thanks to Rosetta but this is experimental and thus does not always works.

Is it possible to install a version of clang on a MacBook M1 where the OpenMP libraries are built for x86 architectures?

This should be possible thanks to cross-compilation. At least, Clang theoretically support that (using the option -target). The best way is to retrieve the binaries from a package manager or compile libomp directly from the source code (you can follow the directives here).

Please keep in mind that while x86_64 binaries could be run on M1 processors with Rosetta, libraries of different architecture cannot be mixed together. This means that you should compile all the dependencies (including the one of libomp although it should not have a lot of dependencies).

The best solution (recommanded, safer, faster and simpler) is to use native libraries and so to rebuild libraries for the M1 processors (possibly from the sources if needed).

Generated ffmpeg video seems to be not a real video file

Asked 2020-Sep-18 at 17:03

I try to create a video with ffmpeg and save it to the device with gallery_saver package for Flutter.

The ffmpeg command works well and the video is created. But GallerySaver does not save it. As result I get no error, but a false boolean for the success argument.

This is the ffmpeg output. Is this a valid video mp4 file?

Output is only 5 frames

Make the video and add the audio in the same command. You can loop the images so it makes a proper length in relation to the audio:

QUESTION

ffmpeg seems to output a video with a wrong codec?

Asked 2020-Sep-12 at 09:39

I´m using ffmpeg with flutter and I create a video from a lot of images. The problem: ffmpeg seems to not create a video with a right codec or something else.... please check my description below for concrete informations.

First the code parts:

Creating video from images

-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -shortest $tempPath/$videoFileName.mp4

Adding audio to the created video

-i ${finalSong.path} -i $videoPath -c:a aac -shortest $tempPath/$newVideoFileName.mp4

This is my video output from console on creating this video:

...

ANSWER

Answered 2020-Sep-12 at 09:39

Videos for web playback usually require chroma sampling to be 4:2:0. FFmpeg, by default, will try to preserve the source sampling scheme, so your output is 4:2:2 (see yuvj422p in the output stream).

Use for step 1,

-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -pix_fmt yuv420p $tempPath/$videoFileName.mp4

And in step 2, avoid re-encoding video

-i ${finalSong.path} -i $videoPath -c:v copy -c:a aac -shortest $tempPath/$newVideoFileName.mp4

If there's nothing after the angle-brackets, you can use: (?.+):\s*(?[^<\n]+)\s* example here: https://regex101.com/r/kzseNw/1

Otherwise you'll need to split the regex for the field content into another section and possibly more if multiple angle-brackets can exist. For example of what I'm talking about: Author: JacobCXDev extra stuff here
