Hi there,
I’m using QuickSync transcode in my workflow, it has a picture quality issue when i playback the output live stream. it would have a mosaic picture especially when scene changes or fast motion picture. when scene change happend, the picture will become blur and then it will turn into clear progressively.
CPU: intel corel I7-3770
Input: 8Mbps or 17Mbps 1080i/720i mpegts stream(mpeg2+ac3)
(now transcode 3 input stream, cpu utilization percentage is 35%, GPU around 15%, memory take 8GB of 12GB)
Transcode para:
[HTML]
hd
true
flv:${SourceStreamName}_hd
Hi,
Do you see the same issue if you try using the default transcoding, as opposed to QuickSync transcoding?
default
This will, at least, help eliminate a particular issue that Wowza Streaming Engine may be having with the source stream.
Best regards,

Hi,
This is being handled in ticket #136543

Hi, thanks for the reply
The dufault transcoding is much better, i had making a copy of this two different output videos and shared in dropbox, you might check it
Dropbox
default-transcoding: https://www.dropbox.com/s/kocpj6w0zcf0cz2/default.ts?dl=0
quicksync-transcoding: https://www.dropbox.com/s/s9b0xxnzxffzw4p/quicksync.ts?dl=0
you can find a obvious difference at the time 9th second.
so any suggestions about this?
thanks!
