Hi I am in charge of encoding from DVDs made by a post-production team vob to mp4 to download to our streaming server.
These DVDs contains several files (6 is the most current number) not written the same day and have different "Steams" setting (mapping) some Stream: [0:0.. Data, Stream: [0:1 .. Video , Stream: [0:2 .. Audio video is always mpeg2video, audio: pcm_dvd and Data: dvb_nav_packet some different setting number. _process_ : I do concatenation using copy /b dos command to get a large vob file and then run ffmpeg to encode in mp4 (avc/aac) all is fine thanks to ffmpeg * Time to time the final mp4s are not encoded in the same order than vob and seems due to streams (I supposed it is due to Stream Data ) * If I do encode each separated vob files to vob, then do the _process_(above) the result is always fine * I have tried _process_ using -map 0:v and 0:a without success question is there a map command which is disgarding the input vob mapping do I have to encode using ffmpeg concat command ? Thanks from your advices jacky _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
