Describe the issue

When starting an RTMP stream with the DJI Osmo Action 4, a lot of times MediaMTX will immediately terminate the stream as the audio track is not set up but an audio packet is received.

When configuring a live stream, the DJI app offers the following options:

• Resolution
  • 480p (smooth)
  • 720p (HD)
  • 1080p (UHD)
• Streaming Quality
  • Auto
  • Smooth
  • HD
• EIS (Stabilization)
  • Off
  • Various modes of "Rocksteady"

Pretty much any configuration will result in this error, but from experience setting 1080p/HD will, most of the time, result in MediaMTX actually setting up an audio track and the stream actually working.
Curiously, once one successful attempt has been made, relaunching the livestream with a different configuration will work as well.

The camera is running with the following firmware versions:

Firmware: 01.04.07.10
Camera Firmare: 10.04.00.10

(Not sure why there's two)

Describe how to replicate the issue

1. Start server
2. Initiate RTMP live stream on camera
3. MediaMTX recognizes a connection but won't set up an audio track
4. The stream terminates

Did you attach the server logs?

yes (Excerpts)

Instance of a failed stream:

INF [RTMP] [conn 172.18.0.1:34242] is publishing to path 'glide', 1 track (H264)
INF [RTMP] [conn 172.18.0.1:34242] closed: received an audio packet, but track is not set up

Instance of a successful stream:

INF [RTMP] [conn 172.18.0.1:47558] opened
INF [RTMP] [conn 172.18.0.1:47558] is publishing to path 'glide', 2 tracks (H264, MPEG-4 Audio)

Did you attach a network dump?

Attached are multiple dumps, mostly failed ones and with different quality configurations.
A dump of a successful stream has also been attached.

I'm not sure if there's actually any meaningful difference between the failed dumps, but I attached them nonetheless. dumps.zip
