Who says it should? If that syntax is not defined (and documented), it shouldn't work. As you noticed, you can help yourself with a filter which does nothing. For video, "null" comes to mind, for audio "anull": https://ffmpeg.org/ffmpeg-filters.html#null Your "scale" may alright, but I would probably choose "scale=w=iw:h=ih", as not to risk "scale" doing anything. (Scale can also do other stuff, so I would rather not use it to do "nothing".) > The streams in and out are (or at least I think are) correctly > defined. Sure, but that's not how it's defined. Two [][] next to each other could be two inputs or two outputs as well. > here the complete output with debug informations. > http://pastebin.com/ccHH7Z6L What was the problem with attaching 11 kB here? > Hope it does make sense. Little. You could open a feature request on trac. Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
