ffmpeg live doesn’t work only stills with Yi hack 6FUS

[Vannixxo]

Hello, anyone experiencing the same problem as me? I’m trying to use my Yi 1080p camera hacked with Roleo 6FUS YI HACK

The RTSP works flawlessly with VLC, it is using live555 library.

I’ve tried every setting, resolution, frame rate etc. Even "-rtsp_transport tcp"

ffmpeg instance starts correctly but then I get this from the log when requesting the live stream and in home app I get the red circle icon (so stream not working) and it streams for about 2 seconds then stops on a still frame (that slowly becomes clearly visible without artifacts)

LOG (this is an extract as it is very long):

No one has my problem?

hi! I was able to get it to work. I am using Homebridge on a raspberry PI with a Yi Dome camera with Roleo's firmware. I set video codec to "copy" source is "-re -i rtsp://CAM_IP/ch0_0.h264" and still image source is "-i http://CAM_IP:8080/cgi-bin/snapshot.sh"

Best new year gift! Thanks! It works flawlessly now, and much much better thank stock YI cloud app streaming!

So I don't get why other users are using omxh264 or other video codecs when the YI hack is already passing an H264 stream to homebridge... If a cam rtsp stream is already in h264, shouldn't alway be "copy" the best video codec settings? So ffmpeg doesn't have to decode/rencode anything?

Glad you got it to work. I think the "normal" config is to reencode with ffmpeg so you can change the frame rate, resolution, etc. If you use copy, you can't change any of the video parameters from source.

Okay, maybe not every other camera RTSP is working this well without re-encoding so... and ffmpeg action is needed. In this case, is still strange that ffmpeg cannot process correctly the roleo live555 rtsp stream
