Hi All 

My task is to save app data to video using different codecs. The data source 
is appSrc in ARGB format. 
I've created GstEncodingProfile with following strings: 

video/quicktime   // Container format 
video/x-prores, variant=(string)4444, width=(int)[ 16, 2147483647 ], 
height=(int)[ 16, 2147483647 ]) // Video format 

It doesn't work (favorite -4 "not negotiated" error). Trying different 
"variant" options I've found only "standdard" works, (QT player shows the 
created video is Apple ProRes 422). All other variant choices give error. 
Same time with command line I can save videotestsrc in 4444 just fine. 

What an I doing wrong? 
Thx 
 

Hehe,

Thanks CrazyCdn!!
GStreamer library is a Quicktime replacement

Thanks a lot
