  • Screen capture in CircleCI VMs in macOS [closed]

    16 août 2024, par Anton Shkurenko

    I'm trying to record test videos using either ffmpeg or appium mac2 driver (as far as I know, it uses ffmpeg behind the scenes anyway)

    


    deviceId == 0 is screen capture in CircleCI VM.

    


    In python code is simple :

    


    appium_driver.start_recording_screen(deviceId=0)

    


    Or using raw ffmpeg :

    


    ffmpeg -f avfoundation -i "0" -t 10 output.mp4

    


    But I can't give permissions somehow. Once I start video recording, there is a popup :

    


    permissions popup

    


    And an error :

    


    [ffmpeg] objc[23088]: class 'NSKVONotifying_AVCaptureScreenInput' not linked into application

    


    What I've tried :

    


    basically main are ffmpeg and .machine-agent, others are just out of desperation 🙂

    


          - macos/add-permission:
         bundle-id: /Applications/Utilities/Terminal.app
         permission-type: kTCCServiceScreenCapture
     - macos/add-permission:
         bundle-id: /private/tmp/.machine-agent
         permission-type: kTCCServiceScreenCapture
     - macos/add-permission:
         bundle-id: /usr/local/bin/ffmpeg
         permission-type: kTCCServiceScreenCapture
     - macos/add-permission:
         bundle-id: /opt/homebrew/bin/appium
         permission-type: kTCCServiceScreenCapture


    


    P.S.
Screen capturing via applescript and quicktime doesn't work for me (I can't click "Record" button). What I've also tried : wrap ffmpeg into apple Automator or Apple Script to make a fake app and give permissions to it, but it didn't work neither.

    


  • why does ffmpeg export black video ?

    8 février, par Sling Ring

    i give ffmpeg a simple task which is the following

    


    ffmpeg -i test.avi -c:v rawvideo -pix_fmt yuv420p out.yuv

    


    i try to play the video but it gives a black screen, even in a .yuv player.
ffmpeg supposedly "running"

    


    Is there some human error that i am doing ?

  • torchaudio.io.StreamReader doesn't throw error when seeking to time stamp more than the duration of audio file

    27 mars 2023, par lokesh

    I am trying to get the audio chunk of audio file between specific start time and end time

    


    Consider a audio of duration 10 seconds. Now i need to get chunk from 4 sec to 7 sec

    


    torchaudio.info doesn't give correct num_frames for io.BytesIO flac audio file. So there is no way to find the total number of frames in the given audio to check for out of bounds start offset
Ref : https://github.com/pytorch/audio/issues/2524

    


    What I did to get the chunk of audio with start and end offsets.

    


    def read_audio(audio_file, start, end):
    audio_file.seek(0)
    reader = StreamReader(audio_file)
    sample_rate = int(reader.get_src_stream_info(reader.default_audio_stream).sample_rate)

    reader.seek(start * sample_rate)
    reader.add_basic_audio_stream(frames_per_chunk=(end - start) * sample_rate)

    return list(reader.stream())[0].pop()


    


    This is working as intended for start time less than the duration of audio file. But when we give the start time more than the duration of audio file, It doesn't throw error or return empty tensor.
Is there any way to know the given offsets are out of bounds.
