• Secure ffmpeg streaming connection ? [migrated]

  12 août 2014, par vantrung -cuncon

  I’ve googled & "stackoverflow-ed" but have not found any article about securing the ffmpeg streaming.

  I want to stream my webcam/ desktop screen to the lan/internet but the first thing in my mind is that there’s no way to secure the stream from eavesdropper, or someone that want to alter the stream ?

  Please someone tell me that I was wrong ?

  Update : I’m gona multicast the data using UDP protocol.

• FFmpeg error with multiple outputs

  9 novembre 2017, par lys

  I’m trying to make a stream using a webcam as data input with FFmpeg, but I need to stream a video in addition to the stream. Both features with the same command for a few minutes.

  (If placed separately the recording code works perfectly)

  FFmpeg code :

  ffmpeg -f dshow -i video="Integrated Webcam" -t 300 -c:v libx264 -segment_atclocktime 1 -segment_format mp4 '/meu_video.mp4' | -s 640x360 -ac 2 -f flv -vcodec libx264 -profile:v baseline -maxrate 600000 -bufsize 600000 -r 25 -ar 44100 -c:a libfaac -b:a 128k "http://localhost:3030"

  There are two errors, one when I try to join the two codes using | or \ and the other when I put only the stream code to test.

  Log multiple outputs :

• ffmpeg converted mp4 video format is not playing on html5 video player

  15 août 2017, par alina

  i have converted a video via ffmpeg to mp4 but its playing on desktop pc player like Vlc but not on html5 player or wordpress player.

  Iam using this command while conversion :

  ffmpeg." -i ".$video_to_convert." -i watermark.png -filter_complex 'overlay=10:main_h-overlay_h-10' -c:v libx264 -crf 17 -preset slow -c:a libfaac -b:a 192k -ac 2 -b:a ".$quality." -acodec libmp3lame -ab 126000 -ar ".$audio." -ac 2 -s ".$size." ".$converted_vids.$name.".".$new_format."

  where :

  .$video_to_convert. = input.mp4

  .$converted_vids.$name. = output.mp4

  is there any syntax problem ??????????????????
