• avformat/whip : Add WHIP muxer support for subsecond latency streaming

  16 mai, par Jack Lau

  avformat/whip : Add WHIP muxer support for subsecond latency streaming
  0. WHIP Version 3.
  
  1. The WHIP muxer has been renamed and refined,
  
      with improved logging context and error messages for SSL, DTLS, and RTC.
  
  2. Magic numbers have been replaced with macros and extracted to functions,
  
      and log levels have been altered for better clarity.
  
  3. DTLS curve list has been updated,
  
      and SRTP profile names have been refined for FFmpeg and OpenSSL.
  
  4. ICE STUN magic number has been refined,
  
      and RTP payload types have been updated based on Chrome's definition.
  
  5. Fixed frame size has been refined to rtc->audio_par->frame_size,
  
      and h264_mp4toannexb is now used to convert MP4/ISOM to annexb.
  
  6. OPUS timestamp issue has been addressed,
  
      and marker setting has been corrected after utilizing BSF.
  
  7. DTLS handshake and ICE handling have been optimized for improved performance,
  
      with a single handshake timeout and server role to prevent ARQ.
  
  8. Consolidated ICE request/response handling and DTLS handshake into a single function,
  
      and fixed OpenSSL build errors to work with Pion.
  
  9. Merge TLS & DTLS implementation, shared BIO callbacks, read, write,
  
      print_ssl_error, openssl_init_ca_key_cert,
  
      init_bio_method function and shared same data structure
  
  10. Modify configure that whip is enabled only dtls is
  
      enabled(just support openssl for now) to fix build error

• AWS Lambda function execution for video

  11 avril, par Abinaya

  I am trying to run my application as Lambda, I am not getting successful eexecution everytime. Its like inconsistent results over testing.

  


  The application uses files from S3 bucket as input, once I have tried to execute Lambda with input being a simple 2 sec long mp4 video using FFMPEG in my application for processing. Lambda executed for 4 or 5 times (not everytime). I was able to see the FFMPEG commands and logs on AWS Log output screen.
he cloudwatch logs on the last execution of this :

  In short, I have created a console application that uses a model (let's say onnx model). This model is utilized in such a way that when my application is started, input is downloaded from s3, once any objects are detected in the input video I am trying to convert that into rendered output video with the use of FFMPEG

  


  Generated output was also uploaded to S3 bucket in .flv format. Sometimes the Output is 0KB .Since then I haven't encountered successful execution for my video case though nothing have been modified in my image that is using to execute the Lambda. What would be the reason for such inconsistent action throughout my testing ?

  


  I am expecting to have a successful output again, consistently. I have run the same application on ubuntu environment inside docker container, it generated output video and uploaded to S3, working as expected. The same docker image was pushed to ECR and I get no output. Is Lambda not compatible for FFMPEG usage ?
I have been struggling with this issue for days, Any help would be appreciated.
