[vlc] VLC not playing audio from RTSP server

[Gerard Castillo Lasheras]

Hi all,

I'm trying to playback audio from an RTSP server that already works with
ffplay and mplayer.

The transmitted format is PCMU/48000/2 with payload type 96.

The output message from the vlc is as shown:
[0x901468] pulse audio output debug: cannot synchronize start
[0x901468] pulse audio output debug: deferring start (9915 us)
[0x901468] pulse audio output warning: starting late (-251 us)
[0x901468] main audio output warning: buffer too late (-16120153 us):
dropped
[0x901468] main audio output warning: buffer too late (-16110267 us):
dropped
[0x901468] pulse audio output debug: changing sink 1:
alsa_output.pci-0000_00_1b.0.analog-stereo (Built-in Audio Analog Stereo)

Then, it get lost here:
[0x901468] main audio output warning: buffer too late (-3392242 us): dropped
[0x901468] main audio output debug: inserting 46535 zeroes
[0x901468] main audio output warning: playback way too early (-120008):
playing silence
[0x901468] main audio output debug: inserting 5760 zeroes
[0x901468] main audio output warning: playback too early (-50004):
down-sampling
[0x901468] main audio output warning: timing screwed (drift: -110003 us):
stopping resampling

And, finally, VLC seems to properly get the increment (to be in sync.
thanks to the RTCP packets) of timing in the GUI but without playing
anything.


Is it a known issue? Does anyone has an idea of which is the problem?

Thank you in advance,


Kind regards,
