Open https://jernoble.github.io/samples/bin/media-recorder/bip-bop.html
By default MP4 is selected with. Click on Start wait a few seconds click on stop.
On the right side, it shows the first frame (it has 000001 in the counter).
Now click on reset, select webm/vp8 and repeat the step above.
The frame showing on the right is typically 3, sometimes 4.
The first 2 frames have been dropped.
This occurs when video is received before any audio, we drop the samples as we set that timestamp 0 is the start time of the first audio frame.
