Description

I have the "Happy Cow I-Spy" toy with the wi-fi camera that casts live video encoded with mjpeg. I try to connect the toy expecting to seen the video stream: ffplay rtsp://192.168.1.1:7070, but seen green screen only with small strip of image at the top. Sorry for screenshots, I have'nt the plain text output, except an error msg:

mjpeg_decode_dc: bad vlc: 0:0
error dc
error y=1 x=0

  • Component changed from ffplay to undetermined
  • Version changed from 4.2 to unspecified

Please test current FFmpeg git head, test ffmpeg instead of ffplay and please post the command line you tested together with the complete, uncut console output as text, do not attach screenshots.

  • Version changed from unspecified to git-master

Please test if the following allows to save a sample stream that you can attach here:

$ ffmpeg -i rtsp://192.168.1.1:7070/webcam -vcodec copy -map 0:v:0 -f rawvideo -fs 2200K mjpegstream.dump

Does the original rtsp stream work with vlc? With which other software does it work?

comment:5 Changed 14 months ago by anhsoft

VLC is plays exactly like ffmpeg/ffplay, i.e. output a green screen with a small strip at the top. The original android soft works correctly (https://m.vk.com/away.php?to=https%3A%2F%2Fapkpure.com%2Fru%2Fi-spy-mini%2Fcom.leo.jg270.Controler.jgremoter)

comment:6 Changed 14 months ago by cehoyos

I have a suspicion that the stream does not conform to the specification and has to be reverse engineered - but I am happy if somebody corrects me!

comment:7 Changed 14 months ago by cehoyos

  • Component changed from undetermined to avformat
  • Keywords rtsp mjpeg added
  • Priority changed from normal to wish
  • Type changed from defect to enhancement

comment:8 follow-up: Changed 14 months ago by cehoyos

The application uses libavformat to receive the stream, it may make sense to ask them which options are needed / how they patched FFmpeg.

comment:9 in reply to: ↑ 8 Changed 14 months ago by anhsoft

Replying to cehoyos:

it may make sense to ask them

I asked them, no answer yet.
Maybe this is encription of stream, because the original brand maker does protect itself against fake branding
