I play the simplified ts file using smplayer -ss is the start in the ts
file, -t is the duration to add
to the -ss value (I would have prefered the absolute end avoiding a
Where do you take that time offset value from?
You mean you extract the various component (audio, video) into separate
I'm also working on such
kind of scripts right now, because I want to remux especially HD
recordings to MKV. In the case of movies broadcasted by ARD HD or ZDF HD
(7...@50hz), they are full of so-called filler-NALUs, which can be
removed just by muxing into MKV not directly by ffmpeg, but by mkvmerge,
which shrinks a 10GB movie to about 3GB.
and then reassemble them using mkvmerge?
Yes I know this is why the "async 2, (+ vsync 2 for récent ffmpeg
version)" is there. Without them I have the audio and the video out of
sync just like you.
My problem is still A/V sync,
all the original TS chunks (I also record into 200MB pieces, because of
fast editing in VDR) show video delays for each audio track of over 1
second, which is also very noticeable ion the final converted MKV. The
delays are reported both by tsMuxeR and mediainfo see for example the
"Video delay" value below:
ffmpeg -y -i simplified1.ts -vcodec copy -sameq -acodec copy -vsync 2 -async 2
-f matroska 1.mkv
I'll post the mediainfo on the ts and mkv when back at home.
