• Missing Library Error in Mac Catalyst when distributed through Testflight

  25 avril 2023, par STerrier

  The iOS version of the app is functioning correctly on TestFlight, and there are no issues when building the Mac Catalyst version of the app from Xcode. However, when distributing the app to TestFlight for Mac Catalyst, the FFmpegkit library fails to load, resulting in a crash. The crash report indicates that the library is missing and cannot be located in the designated file path.

  


  Specifically, the crash report states that the library could not be loaded from "@rpath/ffmpegkit.framework/ffmpegkit". Despite extensive efforts, I have been unable to resolve this issue.

  


  This is error message in the crash report.

  


  Termination Reason : Namespace DYLD, Code 1 Library missing&#xA;Library not loaded : @rpath/ffmpegkit.framework/ffmpegkit&#xA;Referenced from : <9162F8B0-7112-310B-8EDA-59766087927F> /Applications/MyApp.app/Contents/MacOS/MyApp&#xA;Reason : tried : '/System/Library/Frameworks/ffmpegkit.framework/ffmpegkit' (no such file, not in dyld cache), (security policy does not allow @ path expansion)&#xA;(terminated at launch ; ignore backtrace)

  &#xA;

  Are there any alternative solutions to resolve this problem ?

  &#xA;

  UPDATE

  &#xA;

  &#xA;
  • I tried Eugene Dudnyk Solutions but I still received the same error

  &#xA;

  • I checked the package content found in Testflight and the paths are correctly matching the following /System/Library/Frameworks/ffmpegkit.framework/ffmpegkit

  &#xA;

  • I ran the app scheme as release within Xcode and it build and ran fine with no issues

  &#xA;

  • I manually loaded the signing certificates for mac catalyst and still getting the error

  &#xA;

  • Deleted all derived data

  &#xA;

  • Deleted and reinstalled Xcode and also tried previous Xcode versions.

  &#xA;

  • Deleted the project completely

  &#xA;

  &#xA;

  I tried most of the solutions mentioned in this post with no avail.&#xA;iOS app with framework crashed on device, dyld : Library not loaded, Xcode 6 Beta

• How to set fps in python decord library ?

  5 octobre 2020, par Sathish Kumar

  package link : https://github.com/dmlc/decord

  &#xA;

  I am using decord to extract frames and it does a good job, by default it uses video fps.&#xA;Lets say i need to extract frame at 0.2 fps.

  &#xA;

  example : i have a video at 48 seconds and its fps is 30.&#xA;when i extract i get 1440 frames

  &#xA;

  But, I need to specify the fps like 0.2&#xA;so , the output should be 10 frames.

  &#xA;

  PS. In ffmpeg, we can specify the fps while extracting. I am asking in the same way.

  &#xA;

  My code :

  &#xA;

  from decord import VideoReader
from matplotlib import pyplot as plt

vr = VideoReader("nature.mp4")
vr._avg_fps = 0.2  ##Not worked
for i in range(len(vr)):
    frame = vr[i].asnumpy()
    plt.imsave(f'{name}_Frame_{i}.jpg',frame)


  &#xA;

  Help appreciated

• ffmpeg shutting down when stream is silent

  7 février 2017, par chr_lt_ney

  I am running ffmpeg in a Linux environment, where I merge the audio stream from an Icecast-stream and a static image in order to be able to stream that to Youtube.

  At times, the Icecast stream get’s very silent, sometimes for almost a minute. That is intended to happen, due to the nature of the content. But, when the stream get’s too silent, ffmpeg just shuts down with no notice.

  This is how I start ffmpeg :

  ffmpeg -loop 1 -r 30  -s 1280x720 -i /var/www/html/files/youtube/image.png -i http://my-stream-to-icecast:8000/my-mount -c:v libx264 -preset fast -tune stillimage -crf 18 -c:a copy -shortest -pix_fmt yuv420p -f flv rtmp://a.rtmp.youtube.com/live2/my-youtube-key

  Any ideas on how to solve this ? And/or how to optimize the above ?

  Thanks a lot !
