Are you using the version of the client that was pushed yersterday?

[danielpetri1]

Can you try with the reference recording? You need the " " around the link

[dragancevs]

I had old version. Now with new version it shows 404 error. I have tried to enter the url both with and without " " . When i put the link to the web browser it is working. Just files /shapes.svg and /video/webcams.mp4 are not on the server (404 error) C:/Ruby30-x64/lib/ruby/3.0.0/open-uri.rb:364:inopen_http': 404 Not Found (OpenURI::HTTPError) from C:/Ruby30-x64/lib/ruby/3.0.0/open-uri.rb:741:in buffer_open' from C:/Ruby30-x64/lib/ruby/3.0.0/open-uri.rb:212:inblock in open_loop' from C:/Ruby30-x64/lib/ruby/3.0.0/open-uri.rb:210:in catch' from C:/Ruby30-x64/lib/ruby/3.0.0/open-uri.rb:210:inopen_loop' from C:/Ruby30-x64/lib/ruby/3.0.0/open-uri.rb:151:in open_uri' from C:/Ruby30-x64/lib/ruby/3.0.0/open-uri.rb:721:inopen' from download_client.rb:22:in block in download' from download_client.rb:21:inopen' from download_client.rb:21:in download' from download_client.rb:32:inblock in

It seems that the webcams.mp4 file is webcams.webm on our server and file "/shapes.svg" is on the server just from some reason it was not found on first attemtpt to connect.

edit presentations.yml to have -mp4, and new recordings will have .mp4 generated. needed for working on MAC/IOS devices.

I know this, but server administrator don’t want allow mp4 format. He is saying that mp4 and webm together consumes too much disk space.

[hostbbb]

only need -mp4, if you need to support apple/ios devices this should be the setting... (webm not needed)

you can also use ffmpeg cmd line changes and make daniels script also work with .webm

[danielpetri1]

If you replace every instance of .mp4 with .webm, the script should still work.

Did you manage to download the files?

Kind regards, Daniel

[dragancevs]

I have changed every ".mp4" to ".webm" in the *.rb files . I had also rewrite the "presentation-timestamps" to "presentation_timestamps". Now it shows new error [AVFilterGraph @ 0000012efc694740] No such filter: 'scale=w=1280:h=720:force_original_aspect_ratio=1,pad=1280:720:-1:-1:white' Error initializing complex filters. Invalid argument

[danielpetri1]

I don't know what could be causing this error. Does the whiteboard render with this command?

ffmpeg -f concat -i whiteboard_timestamps -c:v libvpx-vp9 -b:v 2500k -pix_fmt yuva420p -metadata:s:v:0 alpha_mode=\"1\" -vsync vfr -auto-alt-ref 0 -y whiteboard.webm
