• 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 :

• stream 0, timescale not set when concat video using ffmpeg

  17 février 2018, par no name

  I have 2 video which i want to add them together so i make a text file which contains the file names

  file No-fade_25fps.mp4
  
  file video.mp4

  then i start using this command

  ffmpeg -f concat -i ffmpeg-sound.txt -c copy final_output.mp4

  the problem is i got this from ffmpeg

  the result give me a video mp4 file with a long duration like 46:33:20 and it not work, and iam sure that both videos have same reslution.
  what i tried is to use this command to convert the video

  ffmpeg -y -i No-fade_25fps.mp4 -r 25 -s 1280x720 -c:v libx264 -b:v 3M -strict -2 -movflags faststart destination.mp4

  and when i concate them again it worked and give me result mp4 file which have a right duration and worked fine but without a sound, because the first video file i use is muted no sound in it and second one contains a sound.
  my question is how to concate those videos togther without this problem also what make the video have the problem of this long duration and when i convert them using the command line it worked ?

  what i want is to add any number of videos togthers without a problems like this they all have same reslution and frame per second is there something else need to be checked before i start merge videos ?
  Update
  this what i get when i use the command without copy codec

  By what I understand is that there might be some image file which can be corrupt which causes ffmpeg to fail in creating video from images.Is there any way FFmpeg can ignore that corrupt image file and create video from other image files ? Is there any change i can make in command to prevent this failure ?
