Also having a black screen

[jimmy9065]

I have checked all the previous issues but couldn't find a solution for me. I'm using remarkable2 (ver 3.5.2.1807) this is the log I have

I can ssh into the remarkable and I check the /dev/shm/ there is no file there. I thought it suppose to have a /dev/shm/swtfb.01 according to #86, right?

I also did ps |grep restream and this is what I got

 1173 root     11172 R    restream -h 1404 -w 1872 -b 1 -f :mem:

which does make sense since I don't have the swtfb.01 file and this is suppose to happen according to the script.

wondering what I missed in the instruction. any idea?

/dev/shm/swtfb.01 is only available if you have rm2fb installed. rm2fb does not support 3.5.2.1807 currently.

[jimmy9065]

thanks for the prompt reply @Eeems

1. so do we have to use rm2fb to use reStream? ( in the script it does have logic to handle the case when swftb.01 is missing, but not sure if it suppose to work)
2. also, assume rm2fb is working, do I need to install that separately? (didn't see this step in the readme so I thought it comes with restream maybe :joy: )

If rm2fb is not installed or running, the file does not exist, so it instead uses the other settings.

To use rm2fb, you would install that separately, and only if it supports your OS version.

thanks for the explanation! last question, do you know if "other settings" would work for reStream? I mean I'm still seeing black screen so it either means that "other settings" is not working for me or "other settings" doesn't work at all for reStream.

Since you have a black screen, no, they are not working. See #95 for some conversation on possible different settings to use.

To address the dark image issue, add an eq=gamma=10 filter, like so:

video_filters="$video_filters,transpose=3,eq=gamma=10:contrast=1.15"

The contrast filter offsets some of the defects introduced by the gamma=10 filter, especially visible with thin lines.

See here for detailed ffmpeg documentation.

This should be fixed in the latest release by #100. Let me know if you encounter any additional issues.
