When I prepare a file for HDS using Adobe's f4fpackager tool I experience "popping" in the audio. It seems to be related to the fragment size, smaller size more often, but doesn't nessicary happen once per fragment.
I have tried multiple encoding options to address this. I am using h264/aac with keyframes every 24 frames and a framerate of 24 and doing "--keyframe-intervals-per-fragment 20 --frames-per-keyframe-interval 24 --frame-rate 24" on the packager
I also tried running Adobe's "sample2_1000kbps.f4v" file from the webroot/vod through the packager and playing it back using their integrated player (/webroot/index.html) and experience the same issue. I did this using the packager's default settings.
This is single bitrate streaming.
Is anyone else experiencing this issue or have any ideas of what I could try?
I tested with the packager, downloaded seperately as 'adobe_f4fpackager_4_5_1_windows_x64.zip', its version is: "F4fpackager version 4,5,1,484".
I tested against one packaged with FMS version "Adobe Flash Media Server 4.5.0 r297"
The audio popping was an issue with FMS, precisely when content was fragmented using JIT which is fixed in FMS 4.5.2. I am not sure you should be seeing this when fragmenting through the f4fpackager.
Can you please send me the URL that you are using to access the Adobe sample video - sample2_1000kbps.f4v ?
Also, please update your FMS to the latest 4.5.2 from here:
And let me know if you are still facing the issue.
