How to capture audio/video streams

[TheBang]

It looks like we're getting another go at this. Stream has started back up at the beginning again. I'm using Jaksta on my mac with success at the moment.

Did you have to do anything special to get Jaksta to work? It's doesn't seem to be doing anything for me when I go to the Lolla stream.

BTW, I believe Jaksta is made by the same people who made Replay Media Catcher.

actually there's no reason why your version would not save "mp3/TS" chunks ? even replay media catcher 4 was doing that without mp2, are you sure ti have activated everything needed ? Also : I still have for now a good connection, i'll try to capture again

I'm using version 5. Do I need to add a ts entry to replay media catcher? What would be the proper format for that?

Can you give the step-by-step instructions for that, please? I had trouble figuring out how to do that with VLC.

Re vlc: Here are the options that I'm using:
vlc -I dummy -vvv "insert url for latest m3u8 playlist here" --sout-file-append --sout=file/ts:foobar.ts
-I dummy: no interface
-vvv "insert url for latest m3u8 playlist here": sets the url to download
--sout-file-append: need this option because it will otherwise just save the file specified in sout over and over again, overwriting what we want; this way, it appends it to foobar.ts which is a ts file that I've already created
--sout=file/ts:foobar.ts: we want to output to a file, encapsulating it as a ts, with a file name of foobar.ts

However, this only seems to work on my linux machine and not the mac. I'm not sure if this is some weird linux quirk or what.
Edit: both are running VLC 2.0.7.

Edit2: Nevermind. VLC doesn't work because the m3u8 playlist isn't regenerating totally new chunks... it's recording 1 2 3 2 3 4 3 5 etc. I guess if I figured out how to name the chunks based on time stamp instead of appending them this could work, though it'd be a pain to stitch together.

No, not really, it should do it as it does for us, it does save them as mp3
Quick note: @TheBang my upload is finnished, my download too, we definitly should have the same thing now, this chunk exchange is really an excellent way to capture streams !

Content type: video/MP2T
File Extension: ts

Thanks for the vlc instructions. I'll check them out

[cynicmuse]

Thanks y'all. I hadn't run mediainfo on what Replay Media Catcher was calling .mp3 files before I'd killed all of the mp3 options.

[ninjaw]

I just had a look a full MKV of what we have, it's quite good ! I called people with details for chunk downloading, we should be ok !

I had to play around with the settings a bit before I got it to capture the chunks as numbered files. I've got the following set in preferences:

I start the youtube stream in my browser then I start a fresh instance of jaksta (already in monitor mode). Hope this helps.

Here we go (again)!

For now it's perfect for me ! I have news trop live recording, i clicked 'erase' on the fucking MPEG main file ans now i dont See it anymore ! (Easier from the small interface) i can confirm this shitty file is encoder live ! When you click live info on it you can see the ffmpeg command... Fucking useless !!

I'm out. I walked away for a minute and replay media catcher died. I'll blame it on that 2gb of RAM. I'll upgrade to 64 bit windows before the next live stream. Thanks for all of the help. Good luck.

Keep in mind we just need to get all the pieces collectively. If you've got/getting numbered chunks we're in good shape.

[cynicmuse]

Sorry. RMC 5 is seriously borked when I restarted it. I now have 3 copies of the mpg all re-encoding with ffmpeg simultaneously while not getting any of the ts files, at which point it crashed If anyone needs the first 250 files, I can help.

[ninjaw]

Exactly : To avoid a lot or crash i ask To erase the MPEG from the tool, every song, each time it's crashin i have To force close chat awful ffmpeg. Or course the fucking tool recreate a ffmpeg. Plz hang on ! De may need missing chucks

Carefull if you dont forceclose thar ffmpeg shit it will continue working and create many fullhd stream !

It looks like I've got a contiguous run of files from the beginning to end (including the credits). About to merge them and see how it looks.

Replay of NIN set is 1080 chunks (15304-16383)

Directly followed by credit roll 34 chunks (16384-16417)

VLC details (from first chunk):

[ninjaw]

Nin including fulll intro and credits are 15303-16417 (16418?) checking my stuff : At first look chunks may be exactly cut the same way as first time

[ninjaw]

Here are chunks i miss 15492 15773 16071 16073 16077-16100 16193 16197 16397-16402 16404-16407 16410

[ninjaw]

chunks aren't cut the same way between stream & replay...

[ItsJustDave]

During 'Copy Of A' 15366 appears to be a copy of 15365.

[Moebius]

try to regenerate the segment URLs, it's possible to do it, you have to guess at the clen (use a binary search). also some other important detail I'm forgetting but maybe you can figure it out.

the urls themselves are live for at least a few hours after the stream ends.

I confirm that

Putting these to a dropbox public share now.

EDIT: Also, I'd suggest whoever puts the final product out watches through beginning to end in case there's other duplicated chunks.


md5s generated from my chunks http://www.sendspace.com/file/xkwz4z

Note that the duplicated chunk has 2 different md5s, the first chunk was slightly larger. I haven't determined if the first or second is the better one to use.

Are you saying this is a bug in the stream or just a strange coincidence? i.e. are you going to editing out one of them?

It was a bug in the stream. I've compared sequences (3 chunks before, 3 after) with one or the other in the middle and they are indiscernible to me.

Only 23 files passed your md5 test

Fantastic ! my list looks complete however there could be dead chunk, we experienced that before

With the chunks you lost and the non-matching md5s, I'm thinking the data I've got is more likely to be accurate. Hopefully someone else who pulled chunks (even for a brief time) can run md5s as well?

No, i was already said by others that files aren't compatibles, must be teh TS header, Actually someone just PMed me the missing chunks from the first stream ! (exept the dead chunk)
