Where do you take that time offset value from? 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. 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

Re: [vdr] merging correctly several .ts files to a single ts file or better mkv

2010-04-01 Thread Eric Valette



Where do you take that time offset value from?
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 
substract...).

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.
You mean you extract the various component (audio, video) into separate 
files

and then reassemble them using mkvmerge?

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:
   
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.


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.

So for now you're determining that value sort of experimentally?

Yes, I'm demuxing all the 000xy.ts files in all their component streams
with ffmpeg for now first, then multiplex the ones I want with mkvmerge.
I might switch to tsMuxeR, maybe also convert back to cleaned-up TS from
MKV also with tsMuxeR to make the smaller recording again playable by
VDR (I've read in the vdr-portal.de forum some users already
experimented with this).

No. This is not the lag beween audio and video this is the timestamp 
displayed by smplayer when the video really starts (you have 2 min 
before and 10 min after by default with vdr that I want to cut).

I'm not a codec format spécialist but do individual codec have their own 
absolute time stamp? so that you can sync them when multiplexing them 
later on? The lag in the TS stream is not constant by any mean at least 
on french HD stream, I keeps getting higher and highger if I do not 
force to sync them (up to a point it crash the player)


By simplified you mean the merged ts?
   
No the one where I removed anything not needed (subtitles, foreign 
language, ...). I have 6 stream when I actually only need two.

So I strip down the ts stream first and then remux.

 Hi,
 
 I've been botten by the 2GB file size split and would like to:
 1) create a single file. cat *.ts  result.ts does not work well
 because if I watch the resulting file with mplayer, i get out of sync
 video and sound at the original split location

I don't see why there should be any interruption at these points.
VDR simply switches from one file to the next when recording.
There is nothing special at the beginning or end of the files.

 2) edit the resulting file to remove uneeded time stamp (beginning
 and end typically)

What uneeded time stamp do you mean?

Well I do not understand either but try with smplayer and you will see 
strange thing happen (slow motion; out of sync, bad timestand displayed, 
...). Each .ts works fine in mplayer, not the result of the cat command.


Note that its VC1 + eac3 (HDTV in france).




 2) edit the resulting file to remove uneeded time stamp (beginning

Removing part of the record that is not what I wanted to record 
(typically a few minutes before and after the complete record).
