Optware/Entware Support

[AustinSaintAubin]

I am having some issues getting Optware/Entware installed.
The main issue I have right now is that the kernel does not support any of the file systems I need. Mainly I need to be able to mountext3.

I have partitioned my SD card to have a ext3 partition (see pic)

You will get the following error message if you try yo mount a file system that the kernel does not support.

[root@wyze-cam-v2:~]# mount /dev/mmcblk0p2 /opt
mount: mounting /dev/mmcblk0p2 on /opt failed: Invalid argument

The problem is the the file system does not support... and of the common partition types.

I have found a work around to do some testing with Optware/Entware by mounting it into the temp directory.
This is NOT a permanent solution, just allows for testing.

Entware

Entware is a more current version of Optware with more features. Its recommended as a replacement for Optware.

#Mount /opt into TEMP Directory
mkdir "/tmp/opt-tmp"
mount -o noatime -t ext3 -o bind "/tmp/opt-tmp" /opt

# Install Entware
wget -O - http://pkg.entware.net/binaries/mipsel/installer/installer.sh | sh

# Load Entware Profile (Sets new bin path, you can add this to your .profile)
. /opt/etc/profile

# Add Entware Profile to User Profile.
cat >> /etc/profile <<"EOF"
# Load Entware Profile
. /opt/etc/profile
EOF

# Update Entware
opkg update

# List [Packages](https://pkg.entware.net/binaries/mipsel/Packages.html)
opkg list

# Install some packages
opkg install htop nano mc

Optware

#Mount /opt into TEMP Directory
mkdir "/tmp/opt-tmp"
mount -o noatime -t ext3 -o bind "/tmp/opt-tmp" /opt

# Install Optware
wget -O - http://ipkg.nslu2-linux.org/optware-ng/bootstrap/buildroot-mipsel-ng-bootstrap.sh | sh

# Set new bin path, you can add this to your .profile
export PATH=$PATH:/opt/bin:/opt/sbin

# Update Optware
ipkg update

# List Packages
ipkg list

# Install some packages
ipkg install nano mc

NOTE: All installed packages will be lost on reboot... because this is mounted to /tmp, and not a persistent storage location... like ext2/ext3/ext4 partition on the SD card.

Any help would be appreciated.

You can try to compile and boot a new kernel for the camera. Then you can include all the filesystems you need.

[AustinSaintAubin]

I have tried to follow the documentation related to hacking the firmware, and documenation related to compiling software and the kernel... but keep running into issues.
I really have no idea where to start. I just need the ext3 file system kernel module.

It seems like the issue is really that the kernel modules are not being included... or the soft link is broken.

Compared to some other firmwares like OpenWRT.

I too am having similar issues related to getting optware working and would greatly appreciate a guide on how to customize and compile the kernel. Honestly if someone could just screen record the full process for this setup I'd be happy with that to start.

[EliasKotlyar]

First , you need to download this repository:
https://github.com/Dafang-Hacks/Main
It includes everything which you may need. Then go into kernel folder, and compile it normally using a generic kernel compiling instruction. Something like https://www.thegeekstuff.com/2013/06/compile-linux-kernel/ should to the trick.

Also test #575 that will make optware easier.

Entware Install Guide

This guide shoes how to install Entware onto the SD card.
Spacial thanks to @nik0 & @unmotivagedgene with help on Main #16

Preparations

• Copy Kernel 3.10.14 Ext4 Moduals.zip to sdcard/driver.
• Formate SD card with GParted, ext2, ext3, or ext4.

Thank you for listing the steps needed to installed Entware. I managed to do it, but already put all the init stuff at the end of run.sh before reading the last section, works just as good.

Nice thing about Entware, that I could finally get my hands on ffmpeg to do segmented recording, as most cams do.

This is the command line I am currently running. 15 fps, 1000 kbps, about 8MB/min/file.

/system/sdcard/bin/v4l2rtspserver-master -W1280 -H720 -E MP3:16000:16000 -r 2 -U root:ismart12 -P 8554
ffmpeg -rtsp_transport udp -y -i rtsp://root:[email protected]:8554/unicast -vcodec copy -c:a copy -map 0 -f segment -strftime 1 -segment_time 60 -segment_atclocktime 1 -segment_format mp4 /system/sdcard/DCIM/201807/%Y%m%d-%H%M.mp4

TCP does not work, ffmpeg just waits at the start and does nothing.

Played a bit with recording options, while monitoring the CPU usage. The rtsp server is very demanding. Scales up with resolution, from lowest to full hd between 30-60%. Also enabling mp3 adds another 10-15%. There is not much room for ffmpeg to do anything other than writing out as-is, it just crashes itself and the server if I try it avutil style (-c:a aac). I think it is a bad idea, best is to let the server output mp3 and save it into mp4, which is also a valid audio format there.

Segmenting needs a bit more work, there is a patch for ffmpeg to auto-create directories according to the date string template, but not compiled into this version. Also, background job to delete old files, move files where motion detection kicked in into a separate folder, sync to a samba share. I think that's all to make it work like the original :)

Installing from http://pkg.entware.net/binaries/mipsel/installer/installer.sh gave me Segmentation Faults when running packages from opkg.

Using wget -O - http://bin.entware.net/mipselsf-k3.4/installer/generic.sh | sh solved the problem for me and I can run packages such as nano.
