image snapshot service not working on yi-hack-6FUS_4.5.0_0.1.4

Christian-Krupa commented 4 years ago

i am unable to get an image snapshot from the camera:

$ curl -vv http://xxx.xxx.xxx.xxx:8080/cgi-bin/snapshot.sh?res=low
*   Trying xxx.xxx.xxx.xxx...
...
> GET /cgi-bin/snapshot.sh?res=low HTTP/1.1
...
> User-Agent: curl/7.64.1
> Accept: */*
>
* HTTP 1.0, assume close after body
< HTTP/1.0 200 OK
< Content-type: image/jpeg
<
* Closing connection 0

also the buffer2jpg command does not seem to work:

/home/yi-hack # buffer2jpg --output=/tmp/sd/test.jpg --res=high
/home/yi-hack # ls /tmp/sd/test.jpg
ls: /tmp/sd/test.jpg: No such file or directory

/home/yi-hack # buffer2jpg --output=stdout --res=high
/home/yi-hack #

any idea whats wrong?

RTSP is working properly? framefinder daemon is running? Could you dump the content of /tmp/iframe.idx? hexdump /tmp/iframe.idx

Christian-Krupa commented 4 years ago

rtsp://IP/ch0_0.h264 - works fine
ONVIF - works fine (even faster than rtsp)

framefinder seems to run, are there any debug logs?:

/home/yi-hack # ps ax|grep framefinder
597 root      0:00 framefinder
2840 root      0:00 grep framefinder

iframe.idx is not available:

/home/yi-hack # ls -al /tmp/iframe.idx
ls: /tmp/iframe.idx: No such file or directory

/home/yi-hack # find / -name iframe.idx
/home/yi-hack #

Could you dump the first 100 bytes of /dev/fshare_frame_buf file?

Christian-Krupa commented 4 years ago

Ok, the buffer is empty. Last request. Could you post your config?

Your configuration is the same as mine, I don't understand why it doesn't work. The problem is that the circular buffer does not fill up. If you look at the file /home/yi-hack/script/system.sh you can see that there is a trick to start filling the buffer:

if [[ $(get_config DISABLE_CLOUD) == "no" ]] ; then
    (
        cd /home/app
        sleep 2
        ./mp4record &
        ./cloud &
        ./p2p_tnp &
        ./oss &
        ./watch_process &
    )
else
    (
        cd /home/app
        sleep 2
        ./mp4record &
        # Trick to start circular buffer filling
        ./cloud &
        IDX=`hexdump -n 16 /dev/fshare_frame_buf | awk 'NR==1{print $8}'`
        N=0
        while [ "$IDX" -eq "0000" ] && [ $N -lt 50 ]; do
            IDX=`hexdump -n 16 /dev/fshare_frame_buf | awk 'NR==1{print $8}'`
            N=$(($N+1))
            sleep 0.2
        done
        killall cloud
        if [[ $(get_config REC_WITHOUT_CLOUD) == "no" ]] ; then
            killall mp4record
        fi
    )
fi

If cloud application doesn't start, the buffer is empty. So I start it, I wait for buffer filling and I kill it. Something is not working in this sequence.

If you start cloud application manually and kill it after 5 seconds, the snapshot works?

Christian-Krupa commented 4 years ago

i tried the example from the script:

/home/app # ./cloud &
/home/app # IDX=`hexdump -n 16 /dev/fshare_frame_buf | awk 'NR==1{print $8}'`
/home/app # N=0
/home/app #  while [ "$IDX" -eq "0000" ] && [ $N -lt 50 ]; do
> IDX=`hexdump -n 16 /dev/fshare_frame_buf | awk 'NR==1{print $8}'`
> N=$(($N+1))
> sleep 1
> done
/home/app # echo $IDX
0000

after that i started the cloud tool and killed it after 26 seconds:

/home/app # date;./cloud
Thu Oct 10 19:13:10 UTC 2019
^C
/home/app # date
Thu Oct 10 19:13:36 UTC 2019

there seems to be no change.

/home/app # hexdump /dev/fshare_frame_buf

/home/app # buffer2jpg --output=stdout --res=high
/home/app #

at the same time rtsp streaming works as expected.

Christian-Krupa commented 4 years ago

i got the problem: i configured my firewall that the camera is NOT able to connect to the internet.

i thought that the "cloud" app only initialize the video buffer. but it seems that the cloud app only do so when an internet connection is available.

with an connection to the "cloud" server i get this output:

/home/app # ./cloud

when i now kill "cloud" i am able to take screenshots via the weburl: .....:8080/cgi-bin/snapshot.sh

roleoroleo commented 4 years ago

Now I remember... Another user posted the same issue. I can solve the problem using s different image buffer but I don't know if there is enough cpu. I will try...

roleoroleo commented 4 years ago

Try release 0.1.5.

Christian-Krupa commented 4 years ago

i enabled the firewall for the cam again. now it seems to run as expected. without an internet connection i am able to create snapshots via curl, thank you!
