While sharing videos to a WhatsApp group chat from my phone, a Google Pixel 4a, some participants could not view the video.. They only could hear the contents of the video.

After finding several threads with no resolution and someone contributing a video which did work for the iPhone users I started investigating. https://www.reddit.com/r/whatsapp/comments/1e4q38c/video_sent_from_android_unplayable_on_ios_and_web/ https://support.google.com/pixelphone/thread/290866570/google-4a-videos-on-whatsapp?hl=en https://support.google.com/pixelphone/thread/290626638/since-july-2024-video-sent-on-whatsapp-from-all-pixel-models-cannot-be-viewed-on-iphone?hl=en

I found that there were several differences, one of which was the colorspace encoding. Investigated a bit via ffmpeg and bothering a couple friends which use iPhones I found a workaround.

I was having the chat messages from the App Wallapop, blocked whenever connected to my local wifi network.
I would disconnect from the wifi and connected to the cell service it would work.
Searching online the Keywords "Wallapop network port chat" gave no useful result.

Searching for App network usage traffic keywords landed me to the following Q/A : 
  https://android.stackexchange.com/questions/203868/how-to-view-network-traffic-requested-by-a-specific-app
 
 This led me to test the following OpenSource App [PCAPdroid - network monitor](https://play.google.com/store/apps/details?id=com.emanuelef.remote_capture), https://github.com/emanuele-f/PCAPdroid
 
 This creates a local VPN and views the App requests.

#    Flipper RAW .sub format
#    
#    Having a look at some of the code in lib/subghz/protocols/raw.c
#    - Decoded data is stored as a line starting with the text "Raw_Data: " followed by space delimited integers.
#    - Each line stores a maximum number of integers limited to SUBGHZ_DOWNLOAD_MAX_SIZE ,defined as 512. Then a new line is written.
#    - The sign of each integer represents a decoded signal logic level, positive / negative , logic level 1 / 0
#    - The absolute value of each integer represents the signal level duration. I am guessing this is in micro-seconds
