• How to stream video with Play 2 framework

  28 avril 2015, par davidshen84

  I want to use Play 2 framework to develop a simple video stream function on my website. The videos are in mp4 format.

  I used the Enumerator, and the method discussed at this post. In the client side, I use the <video></video> tag to play my video. I tested my application on 3 latest browsers, but none of them can play my video :

  • Chrome : display a empty player
  • IE : it tries to download the video like a file...i guess it is IE
  • Firefox : display a message saying the video is corrupted

  However, if I download the video file, it can be played in the player. I am not sure whether it is because my video codec does not support streaming, or it’s my code has problem.

• ffmpeg extract video unable to play

  30 juin 2021, par Khánh Phạm Đình

  I use ffmpeg to stream video and show up the camera's frame to window in the same time according to current code :

  


  file record_video_and_showup.sh

  


  ffmpeg -f v4l2 -framerate 30 -i $1  -c:v libx264 -preset superfast -crf 18 -pix_fmt yuv420p  -c:a libmp3lame -ac 2 -ar 44100 -b:a 128k -f tee  -map 0:v "$2|[f=nut]pipe:" | ffplay -an pipe:


  


  to record video and show up :

  


  ./record_video_and_showup.sh /dev/video0 test.mp4


  


  finally, we get file test.mp4 but can't play it on app such as vlc. When we open it on google chrome, it can run but the start and end time were incorrect.

  


  Can anyone help me ?
