Kristijan Vrban commented on ASTERISK-26554:
--------------------------------------------

I can confirm the problem also with Asterisk 16.4.0

Simple to reproduce with:

exten => 101,1,Answer()
same => n,Record(/tmp/myfile.wav,5)
same => n,Hangup()

exten => 201,1,Answer()
same => n,Playback(/tmp/myfile)
same => n,Hangup()

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Formats/format_h264, Resources/res_rtp_asterisk
>    Affects Versions: 13.12.1
>         Environment: Centos 6.8 (64-bit)
>            Reporter: Ian Gilmour
>            Severity: Minor
>
> If you use Record() to record audio & video and then try to play the audio & video back by using ControlPlayback() the audio plays at normal speed, but the video plays at ~1/10th the normal speed. Problem seen with VP8/H264 video & opus/speex audio codecs.
> The problem isn't present in Asterisk 13.11.2.
> The bug appears to be caused by the changes made to fix ASTERISK-26367. Backing off the change set associated with this issue gets me back to a system that plays the video at the expected speed.
