MPEG-2 Transport Stream Support

bochawa · Post by **bochawa** » Tue Oct 16, 2007 7:51 pm

Just an update: the version I compiled myself (Version 0.9.1 (2007101500)) also reported the same "No Valid Title Found" error that I've been experiencing with this one particular eyeTV exported program stream.

Activity window reports: [14:46:09] scan: could not get a decoded picture
Preceded by a lot of: [14:46:09] hb_demux_ps: not a PS packet (00000654)

I'm guessing I have a malformed program stream and there's not much I can do about it?

Yep - In a perfect (or at least better) world the parsers/demuxers in Handbrake would get past this - however the MPEG2 parser is more 'oriented' for DVD Parsing where stream errors are pretty uncommon.

It's possible the transport stream does have a redundant packet in it (the spec supports this - but I've rarely seen it).

If you can work with the transport stream directly you could try chopping off pieces off the front and see if you can get it past the error, you might miss a few seconds/minutes of the program but perhaps that would be OK ?

Thanks for the feedback. I think for this particular file I'll use eyeTV's built in export option - hopefully future recordings don't have this same problem.

When the season DVD comes out, I'll probably re-encode using HB anyway!

awk, would just like to chime in and say thanks as well.

Just picked up an eyetv hybrid and am recording and converting for my atv. Works great. Durations are correct and everything. Outstanding working with some HD content in HB. Thanks again

Hi awk,

I believe that the issue is all in the scan rather than when we encode. We are pretty resilient to errors when encoding.

When we scan errors cause us to bail on that title. I've already changed the scan code to not bail if a preview can not be constructed, it sounds like there are more error conditions that could be ignored.

I don't actually have any of these problem streams and so don't know which scan error conditions are being hit. If anyone does have one that is an issue (and if they don't mind my grabbing it, if it is small) I'll have a go at changing the scan to not be so picky.

Cheers, Ed.

Yep - I saw that change and think it's going to help a lot, I ran into a problem where the scan would abort on a very small stream because the last 10% of the file didn't represent a complete picture (High-Def stream - and it was very small

. Your change made the scan complete and accept that there was only 9 preview images. Very helpful.

I have some problem clips I've collected and once Leopard is out and I have gotten the first release of my project out the door I'll see if I can run them against the latest sources and get some ideas where we're still failing.

bochawa · Post by **bochawa** » Wed Oct 24, 2007 8:57 pm

I just realized that if I set the aspect ratio to 16:9 in eyeTV's display options for the recording, eyeTV will crop to that aspect ratio when using the built-in iPod export feature, yielding a 320x180 video. This eliminates the need for me to use Handbrake to cut out the black bars on widescreen content.

Sorry if I wasted too much of the developer's time with my query - I still appreciate all the work you guys are doing, keep it up!

I was directed to this thread from this one; as noted there, I'm attempting to get HB to play with a stand-alone MPEG2 file. The MPEG2 was created by using VideoReDo Plus to stream-copy join several MPEG2 chapters produced by MagicDVDripper. (The individual chapter MPEG2s are encodable by HB, but the combined file is not due to lack of titles)

I've installed Streamclip 1.1 (using Windows here), but haven't had any luck yet getting it to produce a file HB will open and convert.

How might I do this?

eddyg · Post by **eddyg** » Sat Oct 27, 2007 1:33 am

Maybe you could paste the result of the scan into the forum, it should explain why it couldn't find any viable titles.

Include the whole thing if you could.

Cheers, Ed.

I'm having pretty much the same problem. I've used DVD Decrypter to concatenate all of the main movie VOBs into a single file. VLC plays it fine, but the HandBrake input code isn't robust enough to handle it.

Honeyko · Post by **Honeyko** » Sun Oct 28, 2007 3:56 am

In my case, a DVD with six cartoon episodes and some extras has the whole mass congealed into a single monster file with about fifty chapters. The cartoons are six or seven chapters each. At first, I used MagicDVDripper to create chapter output, and then merged the appropriate chapters into single episode MPEG2 files (Handbrake will not open, and Streamclip wasn't any help re-streaming them into anything HB would open). Next, I tried using Streamclip's merge feature on an ISO of the DVD as well as a drive folder rip of the DVD; in both cases, it gave me read errors at various chapter breaks. It also haphazardly sorted chapters when I selected more than two to merge -- so I would have to merge two, and then the next, and then the next two, etc, and them merge two of those, and then two of those, until I got a full episode. Assuming no read errors dooming the attempt.... Ugh.

I am presently using HB upon relevant chapters directly, but this requires the interim step of ripping the whole DVD to chapter output in order to tell what each chapter is (because HB doesn't have a built-in viewer). While this produces the output I want in this particular case, it gets me no closer to opening previously converted or encoded files lacking proper "titles" and what-not.

I was recently told by a technical support representative that this is a kind of broadcast flag or "conditional access" (or digital restrictions management (DRM) ) added to the signal to be read by their cablebox to limit what can be recorded. (there have been many examples online posted of CableCo DVRs that auto-delete content after a certain time or prevent users from fast-forwarding.) so if anyone from the EFF (e.g. Seth David Schoen) or AVSforum or anyone here in this forum wants to follow up on this, empirical evidence may be examined.

(apparently the business model in mind is to extract rents from the mandatory cablebox by trying to break compatibility with industry standard QAM.)

I am having the same issue as siromega. I am using HandbreakCLI version 0.9.1. The parameters are generated using HandBreak (GUI) version 2.4.1. VideoRedo Plus is version 2.5.4. I am using a patched version of Vista. The source MPG file plays without complaint (at least spot checking it) in VLC Media Player.

Source MPG video is TiVo -> TiVo Desktop -> VideoRedo (remove commercials) then to Handbreak with the PSP settings, selecting the appropriate (and only) video and turning on two pass. When I encode it says

Code: Select all

Last night I recorded an episode of an hour-long 1080i TV show using my HDHR, with the command line util:

Code: Select all

./hdhomerun_config 1011DE85 save /tuner0 super.ts

I'd tested it out with a 10 minute clip of another show on the same network, earlier in the week, and it encoded fine. But this time, with a 60 minute stream, HandBrake spits out the following when I try to encode:

Code: Select all

After that it just repeats the "Bad transport packet" error over and over again.

I've gotten the same problem in the past with .ts files I didn't know the provenance of, but didn't expect it with an untouched stream from an HDHR....

Any clue why this happens, or how I can avoid it in the future? Is it a problem reading > 4GB files, perhaps?

>4gb isn't an issue as all of my .mpg sources are around 10gb.

I have run into the same error when I try to rename a non-Transport Stream container to a .ts file. Did you try:

Code: Select all

./hdhomerun_config 1011DE85 save /tuner0 super.mpg

...maybe your save should be Program Streams and not Transport Streams?

Nope...SiliconDust's FAQ says to save to .ts, and when I try it as an .mpg, HB tells me "not a PS packet" over and over.

HDHomeRun is giving you a transport stream, there's no program stream support.

My suspicion is that you have 'corruption' in the stream (most likely a lost UDP packet since HDHomeRun uses UDP) which means that the repeating pattern of 0x47 every 188 bytes is being broken. i.e. you have a short transport stream packet (or one long one depending on when the corruption occured) The demux code probably needs to be 'hardened' against this such that if the pattern is broken it can recover, probably not too hard it just needs some example bad data.

As you know I'm trying to get something else fixed up right now

But if you can try and cut out the problem area +/- approx. 5 MBytes and get it to me I can probably use it to improve the transport stream demux algorithm.

Hrm...unfortunately, when I trim the stream in StreamClip, the problem goes away, and is replaced by a different one:

Code: Select all

[15:31:31] hb_ts_stream_decode - Unknown Audio Stream type ! 0x6 (6)

...which leads HB to think this:

Code: Select all

  + audio tracks:
    + 1, English (MPEG) (2.0 ch)

...when the stream is AC3.

UPDATE:

Okay, by making some very dirty changes to stream.c, I forced my trimmed stream to encode. I applied a kludge to hb_stream_set_audio_id_and_codec to force it to use AC3 when it wants to use MP2, and set hb_ts_stream_decode to see 0x06 as valid for AC3. Unfortunately, the stream is useless for debugging, since it doesn't have the sync packet problem.

Now, the errors start popping up on the 3rd preview. So I thought, okay, previews are spaced at each ten percent, so I'll just do a trim around that point. But this ends up encoding too. I'd think it was StreamClip cleaning up the problems, but when I do a full-length edit in StreamClip to remove commercials, the bad sync packet problem remains. Just not on shorter trims, even ones that should include the problem spot. Oh...and they all play fine in VLC.

Since I can't seem to isolate the problem area in a small clip, are there any debugging lines I could add to stream.c that might help, awk?

Will it be easy to now let a .ts or .mpg Title be called out as Title =1 instead of 0? Its confusing some and if by chance we start edcoding ripped HD/Blu-ray DVDs (.ts with multiple titles), this could cause an issue.

According to ISO-13818-1 stream type 6 is "PES private". The encoder for this must be putting the audio type in the tags rather than the PMT stream header so it would help to see all the tags in the entry. There's a really excellent transport stream dumper from inkling called atscut. It was available at http://www.nop.org/inkling/dtv/pchdtvr.tar.gz and perhaps at http://sourceforge.net/projects/atscap/. It compiles and runs fine on a mac if you apply the following patch then do "make atscut".

If you can post the full PMT dump I'll try to fix up hb_ts_stream_decode (I'm already whacking on it to add the correct language codes).

I can't seem to get through to anywhere with the code available, but I'll keep trying.

UPDATE:

Okay, I googled my way to an old tarball of atscap and made atscut -- I had to make a few more mods to get it to build, and the output doesn't look quite the same as yours, van:
