Playback does not work for DJI Drone streaming records

[xarauzo]

Which version are you using?

1.15.3

Which operating system are you using?

Linux amd64 standard

Describe the issue

I am using a DJI M3T drone for streaming (via Livestream feature using RTMP) to the MediaMTX server. I have "record: yes" with format "fmp4" (because I want to use the playback feature, only available on fmp4 format).

The streams are being recorded correctly, and I can find them on the corresponding path (and I can open the file with my video player).

However, when using the "playback" functionality, the video does not play. It gets stuck on the first frame (this is using Chrome, when using Firefox it says "Video can't be played because the file is corrupt.".

On the other hand, if I stream using OBS, everything works perfectly.

Describe how to replicate the issue

1. enable record and playback on MediaMTX configuration
2. start the MediaMTX
3. publish with DJI M3T or M4T drone (other may have the same issue, I just have not tested them)
4. stop publishing
5. run the playback on the recorded file
