[FFmpeg-user] Error when opening RTSP with AAC

[Stas Oskin]

Hi.

I'm trying to open a stream from camera, and getting following error:
ffmpeg -i rtsp://192.168.1.1 -vcodec copy -acodec copy -f rtsp rtsp://
127.0.0.1/streamer.sdp

[rtsp @ 0x1ae0a0a0] Estimating duration from bitrate, this may be inaccurate

Seems stream 0 codec frame rate differs from container frame rate: 1000.00
(1000/1) -> 10.10 (1000/99)
Input #0, rtsp, from 'rtsp://192.168.1.1':
  Metadata:

    Stream #0.1: Audio: libfaac, 8000 Hz, stereo
Stream mapping:
  Stream #0.0 -> #0.0
  Stream #0.1 -> #0.1
Could not write header for output file #0 (incorrect codec parameters ?)

Once the audio disabled all working fine.

Any idea why this happens?

Thanks.
