(You are always requested to post the full command line and complete, uncut console output. There is often valuable information in there.) You are using the concat *protocol*. "Certain files (mpg and mpeg transport streams, possibly others) can be concatenated." WMV may just not work (perhaps because it needs to be reencoded for the merge point to work). You may need to try one of the other methods described here: https://trac.ffmpeg.org/wiki/Concatenate Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
