• nodejs aws lambda ffmpeg command failure

  14 juin 2022, par mozenge

  Im running an ffmpeg command to generate a thumbnail from a video that exists on aws s3 bucket but accessed from cloud front. So i try to stream the video in the command. This is implemented in nodejs and the ffmpeg dependency is a lambda layer. The code looks like so

  


  const gifName = `${baseFilename}.gif`;
await execPromise(`ffmpeg -t 10 -ss 00:00:01 -i "${_url}" ${'/tmp/' + gifName}`);


  


  _url is a clound front url. This works when i test locally even via aws SAM cli.
But this fails when testing the deployed fuction. The error output I get is as follows

  Any ideas what might be wrong ?

  


• Can build & make video call with pjsip and ffmpeg

  10 mai 2023, par QViet

  I try to build PJSIP with ffmpeg with this config :

  


  i Follow those step :

  


  

  • build need lib and place in thirdparty folder name ffmpeg

  


  • setup link lib & header already.

  


  • run build with "$configure —with-ffmpeg="

  


  • config_site.h add :

  


  


  


  #define PJMEDIA_HAS_OPENH264_CODEC 1 
#define PJMEDIA_HAS_VIDEO 1 
#define PJMEDIA_VIDEO_DEV_HAS_FFMPEG 1 
#define PJMEDIA_HAS_FFMPEG_VID_CODEC 1 
#define PJMEDIA_HAS_FFMPEG 1 
#define PJMEDIA_HAS_FFMPEG_CODEC_H264 1 
#define PJMEDIA_HAS_LIBAVDEVICE 1 
#define PJMEDIA_HAS_OPENH264_CODEC 1


  


  


  I see have to enable PJMEDIA_HAS_OPENH264_CODEC , if not, can build success but when import will receive this error :

  


  Undefined symbol: _WelsCreateDecoder


  


  cause miss wels package exits in openh264 lib.

  


  The build with success after all with above config but in this :

  


     pj_status_t status = pjsua_vid_enum_codecs(videoCodecInfo, &videoCodecCount);


  


  the codec info just show 1 codec is "H264/97" -> is OpenH264 codec, i can't see ffmpeg here.
When im start call like normal, see log openh264 init call/ open camera .

  


  What i need step to using ffmpeg, i can see any docs about it

  


  can you help me ?

• Save video using opencv with H264 codec

  31 octobre 2023, par ldiaz997

  This is beyond me and I don't know what I'm doing wrong. I have read that in order to have my video in h265 codec, I need to build opencv from source. Well, I did that, and I also did it for ffmpeg Docker ffmpeg Compiler. But I'm trying to run my application using docker, and I still can't get over the error :

  


  [ERROR:0@93.327] global cap_ffmpeg_impl.hpp:3018 open Could not find encoder for codec_id=27, error: Encoder not found

  I ran the command ./ffmpeg -i 57b3e3a7-ad22-469d-a7ff-cf76ba780664 -vcodec libx264 -acodec aac output.mp4 to test ffmpeg and this was the result.

  The resulting video had an h264 codec. In my opinion, the problem is in opencv. Basically this is what I do in my python code :

  


  cap = cv2.VideoCapture(video)
shoot_frames = []
while True:
    ret, img = cap.read()
    if not ret:
       break
    if some_condition:
       shoot_frames.append(img)
    if len(shoot_frames) > 41:
       out1 = cv2.VideoWriter(upload_path(name , dir), cv2.VideoWriter_fourcc(*'avc1'), int(fps), (int(width), int(height)), True)
       for shoot_frame in shoot_frames:
           out1.write(shoot_frame)
       out1.release()
       shoot_frames = []


  


  Output from print(cv2.getBuildInformation()) :
