(What could mp4sdecd.dll be good for, I am really curious?)
More useful command lines that allow testing with WMP:
$ ffmpeg -i sony-hdr-cx-6-avchd-1080i-9-seconds.mts -ac 2 -vcodec msmpeg4v2
-qscale 5 -acodec ac3 -ab 384k out384v2.avi
$ ffmpeg -i sony-hdr-cx-6-avchd-1080i-9-seconds.mts -ac 2 -vcodec msmpeg4v2
-qscale 5 -acodec ac3 -ab 448k out448v2.avi
(out384v2.avi plays fine with ffplay, mplayer and WMP, out448v2.avi has severe
A/V sync issues when played, transcodes fine with ffmpeg.)
Stopped shortly before end of audio, note the A/V (de-)sync:
$ ffplay out448v2.avi
