• orangepi zero 2w, ubuntu, using a usb webcam ffmpeg to record videos, low FPS [closed]

  28 janvier, par Qingfu Shi

  I use a OrpangePi zero 2w, USB HIK 2K Cam, to record videos.
Ubuntu, ffmpeg installed,
the cmd

  


  ffmpeg -f v4l2 -video_size 1920x1080 -r 25 -input_format mjpeg -i /dev/video1 -vf "transpose=1" -c:v libx264 -preset fast -crf 23 output.mp4


  


  I want the fps to be at least 25, so it looks smooth, but I only got about 4.7 fps.

  but I want the video at least 1080p@30fps. What's the bottleneck ? is it possible to modify the cmd to achieve this ?
OrangePi zero 2w, use an AllWinner H618 cpu, with 1G RAM, 64G v10 sd-card.

  


• Stream to Azure Media Service from ffmpeg, stream can not be played

  24 juillet 2015, par Simon

  i try to send a stream from my RaspberryPI with debian wheezy to the AzureMediaService.
  I followed the instructions of this nice post.
  http://gtrifonov.com/2015/07/02/streaming-live-video-from-raspberrypi-to-azure-media-services/

  After a lot of trouble with the ffmpeg and libx264 builds i think i have it working now, to stream to the rtmp urls.

  INGESTURI="rtmp://office-klokklokmediastream.channel.mediaservices.windows.net:1935/live/3e541bc149754ebd975b95ec3583c949/mystream1"
  
  ffmpeg -framerate 30 -r 30 -s 640x480 -i /dev/video0 -vcodec libx264 -preset ultrafast -acodec libfaac -ab 48k -b:v 500k -maxrate 500k -bufsize 500k -r 30 -g 60 -keyint_min 60 -sc_threshold 0 -f flv $INGESTURI

  But when i try to watch the link in azure portal publish link or with the azure amsmediaplayer it tells me (i have reseted the channel already) :

  "The video could not be loaded, either because the server or network failed or because the format is not supported."

  The public stream url is :

  http://klokklokmediastream.streaming.mediaservices.windows.net/30c3920e-420a-4d33-8938-e79d0db240ff/c9fd3479-0d4b-4643-a3f9-5fd5831985d0.ism/Manifest

  In the linux shell i see the following output while streaming, looks for me as send stream is working :

  "root@raspberrypi:/home/pi/klokklok# ./azure_ffmpeg
