Do you think this is a regression (that would make the ticket important)?

To make this a valid ticket, please provide your command line together with the complete, uncut console output.

I don't have problems with command line!! The problem is with import to timeline in two NLE system (Premier and Edius). Video and audio sync in Quicktime and VLC. Video and audio NOT SYNC in both NLE systems: in Premier and Edius. For example for the command line:
ffmpeg -i output.mp4 -s 1920x1080 -pix_fmt yuv420p -c:v mpeg2video -profile:v 4 -level 4 -g 12 -trellis 2 -keyint_min 3 -top 1 -vtag xd5c -b:v 50000k -minrate 50000k -maxrate 50000k -bufsize 36408333 -c:a pcm_s16le -ar 48K -ac 2 -b:a 192K -y output.mxf Audio and Video is sync and the mxf container is ok. But mp4 container is not ok!!! If you want I can give access to my cmputer through TeamViewer.

But if you want the cmd line it is below (exit with q):

c:\ffmpeg\bin>ffmpeg -i rtmp:// -c:v copy -c:a copy -y output2.mp4

Is this only reproducible if the input is rtmp or also with file input?
