• FFMPEG "Segmentation fault" with stream source and watermark

  4 mars 2020, par Magikey

  I use release : 4.2.2 (static) from "https://johnvansickle.com/ffmpeg/"

  Final code will be on "Amazon AWS lambda"

  Goal : use a url stream and add watermak

  Link to video : ​https://feoval.fr/519.mp4

  Link to Watermak : ​https://feoval.fr/watermark.png

  ./ffmpeg -i "https://feoval.fr/519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

  return "Segmentation fault"

  I have the same error on my computer and on AWS Lambda server

  ./ffmpeg -i "https://feoval.fr/519.mp4" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

  work (but not watermak)

  ./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

  work (but not with stream)

  Thanks you very much !

• FFMPEG profile-level-id size is invalid

  18 février 2020, par Mulham Aryan

  I’m trying to record a RTSP streaming from JVC KY-PZ 100.
  So for that i’m using ffmpeg with some parameters like segmentation, hls, ts, m3u8 etc ...
  i’m always getting an error The profile-level-id field size is invalid (41) and Error parsing AU headers

  This is the output of FFPROBE to debug the RTSP

• Use audio stream overs ssh with ffmpeg on web page

  12 février 2020, par Mauricio

  I need to broadcast the audio stream (WiFi camera at my home) on the website hosted on a VPS.

  Here is the command executed from my home :

  ffmpeg -i "rtsp://172.16.0.201:554/user=admin&password=root&channel=1&stream=1.sdp" -bufsize 24k -vn -acodec copy -f mpegts - | ssh -p 22222 root@mydomain.org 'ffmpeg -i - -vn -acodec libvorbis -ac 1 -ar 8000 -ab 64k -f mpegts "rtsp://127.0.0.1:53350/live.sdp"'

  It seems to work because I get
