Hi,
In some DVB streams, there are TS packets that belong to an mp2 audio
stream, have payload_unit_start set but that are _not_ the start of an
mp2 audio packet. I noticed this when linking against ffmpeg-cvs and
getting Header missing skipping one byte..
However, also the old ffmpeg version
Hi,
Maybe we should go one step further and disable the ffmpeg muxers now.
Or at least mark them as deprecated.
Please don't! I've been using them exclusively with dvbcut and will
work on them again in the very near future (sorry for taking so long,
I've been busy with other projects). I
Hi,
The appended patch fixes the lavfmuxer so it doesn't crash
on a NULL codec. (I have so far only lightly tested, but
it should work at least as before version 31..)

Wolfram.

Hi,
I still get false hits from streamdata.cpp:mpaframe() for audio
streams where MPEG audio frames aren't aligned to packet boundaries.
The reason is that mpaframe() simply looks for a possible MPA header,
and then looks for another MPA header at an offset of the framesize
_or anywhere later_.

Hi,
Yep. That's why there is the sync code. After a
Hi,
Hmm... `bytes' is the distance between two items, and should be an
integer multiple of the frame size.
But items also include the (sometime) non-aligned PES packet headers;
these are not deleted in audio_addpts. For those, the distance is
arbitrary, see the log output below.

Hi,
Neither do I. Can e.g. dvdauthor handle subtitles at all?
Yes, most definitely -- although AFAIK only in vobsub format, it
doesn't do any conversions.
Not as far as I know. And we don't want the normal teletext part anyway,
because it's not related to the program.
Certainly some pages
Hi,
If there really is a locale-dependent conversion going on whenever
converting QString - std::string -- what a horrible misdesign (in
QString)! Is that really unavoidable?
Maybe adding
QTextCodec::setCodecForCStrings(QTextCodec::codecForLocale());
at the start of main() might fix this

That is not true. I can put

Some time ago I tried it but it did NOT work... maybe that was because I

IIRC until recently the -t option wasn't needed at all..
Also I wasn't aware of
Hi,
First a big thank you for your merging work.
* r104 is Wolfram's pipe output patch, with minor modifications. I think
it's better to leave stdout and stderr open, just in case dvdauthor
wants to print any error messages.
You're right, that's better. Still better would be to see the
Hi,
Guess, someone has to open/learn QTdesigner now... ;)
So it's impossible to change dvbcut GUI elements without Qtdesinger?
And normally for a given pipe command not all muxers make sense, so
it is dangerous to let the user choose among all with a combo box (at least

Hi,
I wondered if compiling {make} the above three revs from svn succeeds
for others.
It works for me (but with gcc-4.1, perhaps gcc-4.3 once again gets
tighter).
I'm having the following troubles:

Hi,
Thanks Wolfram, you were spot on; that got me through the first set of
issues, and helped me find:

I also needed to add #includes in tsfile.cpp .
Ok, looks good.
At this point it
compiles, runs and operates OK
Hi,
There is a 10MB sample at
http://www.andrewhakman.dhs.org/sp_dec5.ts.truncated . What is wrong
with this transport stream, and can dvbcut be made to correctly
identify the audio?
The transport stream was recorded with TSReader, and there were no
continuity or TEI errors reported while
Hi,
Recent ffmpeg has changed include file locations (cleaned up
IMHO). With the appended patch it is possible to compile
with the new layout and with the old one in ffmpeg.src
(a bit of a hack with a manual Depends(), maybe someone can
come up with a cleaner solution).

Hi,
I would vote for make/autoconf
My vote, too!
as I am unable to compile dvbcut from SVN

remember, it is still the same -Isrc/PREFIX)/include problem either i386

Sorry for the delay, here is a current i386 build
Hi,
This doesn't work with the included ffmpeg:

Hi,
Based on svn r178, and linking with recent system ffmpeg instead of that
provided by dvbcut,
I observe inconsistencies in fps written to mpg file.
Does the appended patch help?
Cave: Only compile-tested for an older dvbcut version..

Wolfram.

I use ts-cut, hereby announced, shamelessly taking the opportunity:

Warning: it's command-line only, but has practically _no_ dependencies.
