Whatsapp video format support
Solution 1:
I convert video to mp4 using this settings:
- codec: H.264
- resolution: 960x540 (quater of FullHD)
bitrate: 2-5 Mbit VBR
audio codec: aac
- bitrate: 128kbit
And it's working.
Solution 2:
I had the same problem, no matter what video format I used, I still coudln't send videos. I think the problem lies in the audio format, I switched to aac audio format and the couple of videos I wanted to send are now working.
