Getting closer!

I start live-streamer with the command

live-streamer -S ar0130 -B

Next I connect to the rtsp stream via the URL rtsp://192.168.1.240/0 in VLC and get the following output on the camera:

linear mode
hi_i2c_wait_txfifo_notfull->241:
abort! last int_raw_status: 0x750!

hi_i2c_abortprocess->87:
tx_abrt_src is 1.

< the 4 lines above repeats a bunch >

Aptina AR0130 sensor 720P30fps init success!

full log: live-streamer.log

@xuhuashan do you have any ideas of what this error means?

After that I do see some stream info in /proc/umap/h264e:

cat /proc/umap/h264e

However VLC and mplayer is unable to connect, not sure how to debug further...

I will keep digging..

Same problem here, did you solve the problem?

[walnut-engineering]

Nope, never figured it out. I did get a hold of Watson (@xuhuashan) via email and the feedback I got was:

the arguments of the live-streamer of is not enough, you must add the pipeline via -pipe argument,
and rtsp stream via -stream PATH:[,]
for example:

live-streamer -pipe "isp0:sensor=ar0130|videv0|vichn0-0|vpgrp0|vpchn0-0" -pipe "vpchn0-0|vechn0:encoding=H264,br=2048" -stream "0:vechn0"

you can add more rtsp streams via -stream argument, and more pipeline via -pipe argument.

hope this can help you.

Trying that command line seems to start the server, but upon connecting I got a lot of i2c errors; see attached. Watson took a look at the log and said:

live-streamer.log

From the log, your i2c is not working properly. You can check it by following the steps below.

1. Check if the i2c hardware is correct. If you have an oscilloscope, you can view the waveforms of scl and sda pin.
2. Check if the scl/sda pin multiplexing of i2c is configured correctly.
3. Check that the i2c clock is configured correctly.
4. Check if the i2c address in the driver is the same as the actual address of the cmos sensor.

I'm sure its not a hardware issue (its an off the shelf camera that works with the stock firmware)
; so perhaps an i2c config issue; but not sure where to look.

If you have any clues for me that would be awesome!

Hello, Did you see my reply on GitHub? I would love to solve this problem! Thanks!

Hi
can someone pls send me compiled live-streamer, I'm not able to compile it. I'm missing some packages.

Thanks

[walnut-engineering]

Not sure it will work as I think it depends on some kernel modules - build is a bit old but give it a try.
