[asterisk-bugs] [JIRA] (ASTERISK-26554) format_h264: ControlPlayback() running slowly

[Adam Caldwell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=256558#comment-256558 ] 

Adam Caldwell commented on ASTERISK-26554:
------------------------------------------

i got rid of the 1/10 speed by patching main/file.c:

In {{static enum fsread_res ast_readvideo_callback(struct ast_filestream *s)}}
Change this line to have /10 as shown:
{{ast_channel_vstreamid_set(s->owner, ast_sched_add(ast_channel_sched(s->owner), whennext / (ast_format_get_sample_rate(s->fmt->format) / 1000)/10, ast_fsread_video, s));}}

It works for me, but I'm not sure it's the right fix.... so just leaving this comment here

>          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

> 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.
