• Node fluent-ffmpeg killing process kills server - How to start and stop recorder ?

  18 octobre 2024, par Scorpio

  I'm using fluent-ffmpeg in a node application. Recording from the screen/camera to an mp4 file. Would like a server request to start and another request to stop recording (links to a web interface - testing some tech with a view to making an Electron App later with it).

  



  Starting is fine, but cannot figure out how to stop it.

  



  This is the code to start (to run on MacOS) :

  



  recordingProcessVideo = ffmpeg(`${screenID}:none`)
     .inputFormat('avfoundation')
     .native()
     .videoFilters(`crop=${width}:${height}:${x}:${y}`)
     .save(filePath);


  



  This is what I thought would stop it from documentation and reading around the subject :

  



  recordingProcessVideo.kill('SIGINT');


  



  However, when I call this command, the server quits with the following ambiguous message :

  



  code ELIFECYCLE
errno 1


  



  Also, the video file produced will not open as if it quit before it completed. Can't seem to work it out, as from the docs and what people have written, to start and stop the recorder should be to make the process, then kill it when ready. Anyone know the correct way - been looking for ages but can't find any answers.

  



  Using Node v10.15.2 and Ffmpeg version V92718-g092cb17983 running on MacOS 10.14.3.

  



  Thanks for any help.

  


• Android NDK : Aborting. Stop

  6 mars 2019, par Huy Tower

  I’m trying to call C++ method in Java coding.

  I received the Android NDK : Aborting. Stop when defined the Android.mk file as below :

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE    := ffmpeg
  
  LOCAL_SRC_FILES := libs/ffmpeg.so
  
  
  
  include $(PREBUILT_SHARED_LIBRARY)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE    := ffmpeg
  
  LOCAL_SRC_FILES := ffmpeg.cpp
  
  LOCAL_SHARED_LIBRARIES := ffmpeg
  
  include $(BUILD_SHARED_LIBRARY) 

  But if I defined like this, it run successfully :

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE    := ffmpeg
  
  LOCAL_SRC_FILES := libs/ffmpeg.so
  
  
  
  include $(BUILD_SHARED_LIBRARY)

  Questions :

  1 - How to fix this error ?

  2 - In Android.mk file, Can not call libs/ffmpeg.so and ffmpeg.cpp in the same time ?

  People who know this,

  Please tell me,

  Thanks,

  -i anullsrc -rtsp_transport tcp ^
  
  -i "rtsp://xxx:xxx@xxx:8080/videoMain" ^
  
  -r 1 -loop 1 -f image2pipe -i 762141_marquage.png ^
  
  -filter_complex "[2:v]setpts=PTS-STARTPTS[a];[1:v][a]overlay=10:10" ^
  
  -tune zerolatency -vcodec libx264 -c:v libx264 -crf 30 -preset ultrafast -c:a aac -strict experimental ^
