video recv: timeout

[DanielMallia]

First of all I love your work and most things work perfectly but when I run anything that uses the camera I get presented with:

This shows the feed I get when using video_effect.py but I have also tested on keyboard_and_video.py and got the same output although I could still move the drone around with the keyboard.

I have found an opened issue with similar errors but since its been closed and mine still isn't working, thought I should open it again.

I have narrowed the problem down to this line :
container = av.open(drone.get_video_stream())

Hope someone can help out.
Thanks

Can you please help me with this issue @inspectred

#58 (comment)

[DanielMallia]

@pnehareddy1 did you solve this issue? Sorry I'm seeing your message just now but if you still have the issue comment again and I will go through my code to remind myself how I made it work.

[pnehareddy1]

Thanks for asking me again. I am still having the same issue. I think the problem is with my 'mplayer' on 'Ubuntu 18.04'. I am able to play the video from the Terminal by using 'mplayer', but unable to play directly by clicking on the video (able to hear the sound, but unable to view the video). Could you help me with this or can you suggest me any other player that works with 'Tellopy'.

Regards,
Neha Puchakayala

[ricafort]

I am also having the same errors and issue

[Walt-H]

I had to watch the video via Chrome, but I was able to fix this issue on Windows (see comment here)

[samlaf]

I think I found a solution for this.
You just need to add a call to wait_for_connection:

drone.connect()
drone.wait_for_connection(10.0)
drone.start_video()

Alternatively, you can add the call to wait_for_connection directly inside connect, as I did in this pull request.

[SMRazaRizvi96]

I am using ROS Noetic on Ubuntu 20.04 and I am also facing the same issue.
I even added
drone.wait_for_connection(10.0)
But no luck.

Please help.
