Thread: Android video issues when loading a Samba video file from router

Hey all I have the following Java code I did in Android Studio that I am needing some help with.

I am needing to be able to load a shared file from my router (It's running OpenWRT/Luci) with the Samba file sharing turned on. I have tested the code out below to make sure it's finding the file and I can confirm It can find it when it checks for SMB file found? and it comes back true.

When loading local file:


However, the issue is that when I switch over to getting the SMB video it does not load like the other tests that I did - loading it up from local storage.

When loading from SMB file:

For testing it out I'm just using the ADB with the correct device number to send a http request to the built in browser:

adb -s 25131HFDD6222C shell am start -a android.intent.action.VIEW -d http://127.0.0.1:7777/bun33s.mp4

And like I said, it plays when I test it out loading a local file on the device but wont play when using the SMB file.

What am I missing?

It seems that you are having difficulties receiving SMB video. The problem may be due to differences in the boot mechanism between the local computer and the SMB storage. Check that the paths and settings for accessing SMB resources are correct. I had a similar problem when I wanted to remove the background from a video, it’s good that later I found services depositphots.com, which, using AI tools, was able to remove the background without any problem. If these tips don't help you, you can still consider using debugging tools such as inference and logging to identify specific points of failure. If you have the code, please provide it for more detailed analysis.

Soya de-oiled cake emerges as a valuable byproduct in the extraction of soya oil, contributing to the sustainable utilization of soybeans. After the meticulous process of oil extraction, what remains is a protein-rich cake with reduced oil content. This residual cake becomes a versatile ingredient, finding applications in animal feed, agriculture, and various industrial uses. Packed with essential amino acids and proteins, soya de oiled cake serves as a nutritional supplement for livestock, enhancing their growth and health. In agriculture, it acts as a potent organic fertilizer, enriching the soil with nitrogen and promoting plant growth. Its significance extends to industrial sectors where it becomes a component in the formulation of diverse products. Soya de-oiled cake, with its nutrient density and multifaceted applications, exemplifies the sustainable and holistic approach to soybean processing.
