problems loading .tp transport stream files

abman · 6th May 2003, 23:58

I've been playing with converting hdtv transport streams from my MyHD card to SVCD for the past month, and have it more or less working after quite a few headaches. I have however noticed one issue I can't resolve. Every so often a transport stream will not open in either hdtvtompeg2 or dvd2avit3 (trbarry's version). The file opens fine in the MyHD player, but those two apps just lock up when I try and load it. I've had it happen with streams off ABC and FOX. Happened to about 1 out of ever 5 or 6 streams I capture. The streams are all around 7-8gb per hour, segmented into 2gb chunks. I've done some 3 hour streams successfully, can't seem to find anything that separates the streams that errors from the other ones.

Anyone know if perhaps a single bad frame at the beginning could cause the two programs to fail on opening the file? If anyone else has experienced the problem I'd appreciate any input.

Are you setting the correct PID's in dvd2avi.ini? ABC and FOX use audio and video PID's of 21 and 24, respectively, so you need to set this line in dvd2avi.ini:

Code:

MPEG2_Transport_PID=21,24

You can check the PID's used in a TS using hdtvtompeg2.

hdtvtompeg2 crashes just like dvd2avi when trying to load them. I also tried NIC's version of dvd2avi that autodetects the PIDs. no difference. its an issue with the stream for sure, just not sure if there's anything I can do about it. Anyone know of another program I could use to trim the beginning, see if that helps?

Have you tried the cleanup trick using the dvhstool filters described on this AVS Forum thread? It can fix minor stream errors.

A few weeks ago (about 3/30?) I posted a new version of DVD2AVI2 on the DVD2AVI forum. It fixed a problem with multiple streams that in my area could occur on both Fox & ABC. But it didn't tend to cause crashes.

A little before that there was also a new version of MPEG2DEC3 with a similar fix. See:

ya I'm using the latest versions. Actually I'm dumb, a remux of the .tp in ][muxer fixed it up. The resulting .mpg worked fine.
