Create an mp3 from .ts file

[Steve52]

Can someone tell me how to pull the audio track from an h.264 Sage .ts recording and convert it to an MP3?

you'll need a demuxing tool to pull out the audio track, and then something to convert it to MP3. EAC3TO will demux for you, and it also converts to some formats (FLAC, WAV), but not to MP3 directly.

1) get graphstudio, the monogram mp3 encoder, dump.dll (attached)

2) regsvr32 the two filters

3) build a graph (see screen shot); the last filter is dump

4) play

You could do it with SageTVTranscoder:

<SageTVPath>\SageTVTranscoder.exe -i <filename>.ts -vn -acodec mp3 -ab 128k output.mp3

Make 128k whatever bitrate you want. I've used something quite similar to convert quicktime trailer aac audio to ac3.

-doh, or maybe not, looks like the Sage version of ffmpeg doesn't have mp3 encoding enabled.

So lets try this again, but with mencoder:

<pathtomencoder>\mencoder -oac mp3lame -lameopts preset=standard -ovc frameno -of rawaudio -o output.mp3 input.ts

is the syntax for the transcoder documented anywhere?

You can do -h, or it's just ffmpeg, so the ffmpeg docs/info apply.

Stranger,
The Transcoder option does not work, and I think you are saying that above.

I would like to try the mencoder option but I don't think I understand it. Where do you put the file name <filename.ts>? Have you tried this option, and does it work?

[doc]

I don't know about ts files, but I extract mp3's from mpegs using

sagetvplayer -dumpaudio filename.mpg -dumpfile newfile.mp3

it might be worth a try

Sorry, I called it "input.ts", how's that for consistency. And yes it works.

It did work but the quality is poor, and windows media player reports that the file type did not match the .mp3 format. It did play however. I need a high quality mp3 pulled from ts file.
Thanks anyway!

Stranger,
Silly me, I thought mencoder was probably another program within sage. I see now that it is a seperate program that is a free download. I will have to download it and learn to use it. Before I go thru all that, will this option give me a high quality .mp3?

[stanger89]

Well it uses lame with whatever parameters you want, so as far as the mp3 encoding goes, it shouldn't get much better. You could change preset to insane if you don't care about size

I am not having any luck here. I downloaded the windows version of mplayer version 0.6.7 but mencoder was not included with it. From what I read mencoder is a companion program for mplayer, but I don't see any place to download just it. Also I tried to play the Sage .ts file thru Mplayer and it crashed my computer. Not sure why?

eac3to worked very well to get me a flac file

Now 2 related questions... how do I manage a split recording in sage into a single flac file?

What's the best way to break the flac into individual tracks?

I want to thank all those who offered suggestions here, but in the end none of these worked out for me. I was really looking for a windows based software that I could just drag and drop an HDPVR file (.ts) into and create an mp3. After a lot of searching I found that there are a lot of programs out there that will meet my requirements for most video formats but not for the .ts files that sage creates from the hdpvr. I have found one that will however, and it is Quick Media Converter version 3.6.5. I was able to use this to create the mp3 files I needed. The file was very large however so I used another program, Slice Audio File Splitter version 2.0, to split the mp3 file into smaller segments. I thought this might help someone else looking to do the same thing I was. These are free programs, and you should proceed with caution when loading and trying. As always use at your own risk. One of the programs I wanted to test (not one of these) tried to load a trojan virus on my computer. Fortunately my antivirus software stopped it.
