View Full Version : What's the best way to convert ty->mpg in Linux

I've been experimenting with converting ty streams to mpg files using tystudio's typrocess. I then use ffmpeg to re-sample the resultant mpeg to something that is playable on my Treo600 palm phone using mmplayer. I have had some success but it seems that audio sync is just not working right (sounds like a cliche).

I'm thinking the problem lies with typrocess. Is there another binary that can do a better job? I'v read that tystudio has halted development.

EDIT: I need to do this in Linux so I can automate the process more easily. I also don't run a windows box all the time but I do have a Linux box doing various things and is on at all times.

Thanks.

Are you using cut files? I haven't had sync issues if I process the whole recording.

Isn't there a Linux port of tytool's core bits?

Isn't there a Linux port of tytool's core bits? I thought it was a win32 only tool.

Wow, it has been dead for almost a year.

I didn't even know Tynix existed. I dloaded it and was able to create an mpg from a Ty file a lot faster than with typrocess. The only problem is that jdiner went with ncurses instead of a plain ol' CLI. I would prefer CLI because you can always front-end the UI later. As it stands, I have to figure out a way to automate this using Expect but it looks great. Too bad it appears dead on the vine.

Thanks for the pointers and props to Jdiner for providing such a great tool in spite of all the sources of his frustration.

It may also be possible to do it purely with mencoder (http://mplayerhq.hu/). (It didn't work the last time I tried it, and I never did figure out why, but that was a few versions ago.)

I've converted a few ty streams to divx with mencoder I used a small plugin from this forum but I don't think it's needed. if you are going to use mencoder to convert your ty stream to mpeg it will reencode :-/. last I tried TyTools worked under wine.

Use the Linux version of vsplit JDiner included in the TyTool package. Then you can use cron and shell scripts all you want. It can do the ty->MPEG conversion for you, then do your resample etc..

I just downloaded the binary package from the main TyTool post, it has a directory for the unix version in there. It should run on Linux.

I tried using transcode, but it still has timing problems. mencoder works really well, though. I transcode to xvid.

My command lines look like:

VF="pp=vd/hd/dr,kerndeint,hqdn3d,softskip,harddup"
LO="preset=medium"
BITRATE=1450
XOP1="gmc:vhq=1:chroma_me:chroma_opt:quant_type=mpeg:qpel:trellis:hq_ac:
autoaspect:pass=1"
XOP2="gmc:vhq=1:chroma_me:chroma_opt:quant_type=mpeg:qpel:trellis:hq_ac:
autoaspect:pass=2:bitrate=$BITRATE"

mencoder <input> -o /dev/null -vf $VF -oac copy -ovc xvid -ofps 29.97 -xvidencopts $XOP1
mencoder <input> -o <output> -vf $VF -oac mp3lame -ovc xvid -ofps 29.97 -lameopts $LO -xvidencopts $XOP2

Only problem is this encodes at ~9fps on a P4 3.06 GHz. Oh well.

jdiner is including a linux version of vsplit in his releases now. the current version is a version or so behind at the moment.

look for vsplit.

if you don't need to edit things this will create a .mpg or .vob file from a ty file

tytool does work under wine so you can use that for the editing and menu creation
