#7561 — video transcoding softeater.

FromThe Natural Philosopher <tnp@invalid.invalid>
Date2013-03-22 23:14 +0000
Subjectvideo transcoding softeater.
Message-ID<kiiol0$fmp$1@news.albasani.net>
I record TV prtograms.

They end up as .m2t files.
I want to turn them into neat little mpgs and cxlean them up and even 
remove ads.

The first step is to tidy up the execrable crap that seems to be brodcast.

I now have 3 files that I can play, but do nothing else with because 
every single transcoding program I have tried cops out and say 'error'.

ffmpeg.
VLC
projecttX


what else is there to try?

Oh and are there any GUI front ends that don't look like the flight deck 
of the starship enterprise that, say, autodetect what it is, and make 
sensible assumptions when you tell it what you want it to be?

Or actually come with manuals or help systems that tell you what the 578 
controls actually do and mean?

How about avidemux?

Presumably .m2t is indicating an MPEG-2 transport stream.

> every single transcoding program I have tried cops out and say 'error'.

To what format and container do you want to transcode them?

ffmpeg is, as far as I am aware, very picky about one using the correct
command line flags specifying both the video type and audio type of the
input file, so if those are wrong, it is not surpring you get "error".

Expect all that software to be broken to a certain degree...
I've given up all transcoding efforts in the early 200x.

Do either of these help?

Providing us your command line and the error that gets spat out would
help tremdendously.

Nope. it ignores that and starts transcoding,

This is the problem. Broken audio channel I think.

Same with avconv. Same message, same abort.

I've managed to avoid this deprecation warning so far. But I know that
Debian's also switched to avconv so I guess I'll have to head that way
sooner or later.

This is the exciting stuff. You're using -vn to strip out the video,
which leaves the two audio channels. You haven't specified which one to
use so ffmpeg maps the first and ignores the second.

> kbits/s

Ah! You've asked for an audio bitrate of 128 bits/second; you're more
likely to be expecting 128 kbit/sec, so you need "-ab 128k".

Your 128 bits/sec audio stream is also shown here ("0 kb/s") ^^

Not sure about this. I'm hoping for now it'll go away once you fix the
bitrate. If it doesn't please come back here with an update and I'll
dig some more. Most of my stuff doesn't record with errors, though,
so it's tricky for me to test any suggestions.

One of the more helpful ffmpeg pages out there is
http://howto-pages.org/ffmpeg/ which I would strongly recommend you
peruse. (When you have an hour or three.)

Ok trying this and  also the video, since what I want is a cleaned up 
mpeg stream for archival. Or burning to DVD.

Will do.

yes..i had hoped that software would have been good enough not to have

well after correcting the command line to fix audio bitrates and include

I'll check whether it actually completed in a half hour or so. My wife

But I think its crapped out at the same place for the same reason..

MM if you want the source file I could probably post it up somewhere to 
download..

Email me (reply-to is valid). I'm heading out now for the evening but I
can pick it up either late tonight to else some point tomorrow - let me
know if there's a time I shouldn't do so.
