mythpreviewgen fails - no new thumbnails for recordings

[yiannividalis@…]

Hi,

After upgrading from e4fface (before ffmpeg3) to 76cd458, my recordings don't have thumbnails, either in frontend or in mythweb. This happens both to my main system (MBE + SBE) and a laptop I can use as a test MBE.

On my main system, while refreshing the mythweb recorded page, the system log shows:

No other software or hardware change has taken place on either system, only the mythtv update.

Just in case it wasn't obvious, I can see older thumbnails, it the newer ones that don't get created.

[stuartm]

Although it may not seem relevant, please include details of the patches you are using.

[yiannividalis@…]

I will, however, on the test laptop, I don't use any patches and I have the same problem.

converts some strings in mythweb to utf for Greek

[yiannividalis@…]

patch for mytharchive, I found it in a ticket

[yiannividalis@…]

mythweb date formats and minor translation correction, I should ask for it to be included in master

[yiannividalis@…]

eitfixup for my sat provider

[JYA]

Just to be clear, this is with master, not fixes/0.28??

Because your git describe indicates 0.28

[yiannividalis@…]

Yes, I only use the master repo. On the main system:

> git branch
* master
> git describe
v0.28-pre-3612-g76cd458

On the test laptop:

> git branch
* master
> git describe
v0.28-pre-3611-ge3fe0b7

Before each upgrade I run git --reset --hard and git --pull

And I've also tried removing the whole 'mythtv' and 'mythplugins' folders before running 'git --reset --hard', as well as 'make uninstall' and also manually removing the mythtv folders and files under the installation folders.

[JYA]

Hmmm. I had particularly tested mythpreviewgen as it uses the new deinterlacer. When you run the mythpreviewgen command manually with the same arguments as what appears in the log. What do you get?

[yiannividalis@…]

No error shows, but it's strange that the dimensions requested are 0x0. I've also tried with 130x70 (randomly) without success.

Those dimensions aren't used. It means same size as the original frame.

Need to add some logs to find out what happening here. But mp2 audio and video is the type of recordings I have here. So I'm surprised it doesn't work for you.

You're sure that no image is created?

[yiannividalis@…]

Unfortunately, no image is created.

[yiannividalis@…]

Does the frontend program also use mythpreviewgen or does it use its own code? because no thumbnails are there, either.

[J.Pilk@…]

It's working for me, UK DVB-T/T2 in buntu mythfrontend version: fixes/0.28 [v0.28-pre-3592-g34c7003]

[J.Pilk@…]

Sorry, getting confused. That's still mythffmpeg 2.8.5

Ok..

can you run it with the following extra options:

-v playback,libav --loglevel debug

thanks

the preview files are generated by the backend..

but yes, all previews are generated by mythpreviewgen ; the backend fork a process to run it.

what the...???

did you compile from source? what's in mythtv/libs/libmythtv/mythvutil.cpp

did you run make distclean and removed any existing libmythav* from a previous ffmpeg install?

sounds like you have some crap from a previous install.. i can't explain why else you could get such a log

"(myth_av_log) - [AVFilterGraph @ 0x7f43b5f3fb00] No such filter: '818181'"

what the...???

did you compile from source? what's in mythtv/libs/libmythtv/mythvutil.cpp

did you run make distclean and removed any existing libmythav* from a previous ffmpeg install?

sounds like you have some crap from a previous install.. i can't explain why else you could get such a log

I'm removing all mythtv and mythplugins and recompiling as we speak. I hope it was my mistake, however embarassing it may be. I'll let you know in 1-2 hours?

[J.Pilk@…]

Just installed master [v0.28-pre-3592-ge4fface] in Fedora 22. Works for me with UK DVB-T/T2. And this *is* with mythffmpeg version 3.0. Cheers!

[J.Pilk@…]

But I copied the version from the wrong log... master [v0.28-pre-3617-g90195f6]

[yiannividalis@…]

Sorry for the big delay...

I'm now testing with the laptop to keep the family happy. Still getting the same error in the logs about 818181. This is the history of commands I've run prior to this email (that concerns building mythtv). By the way, all systems are on opensuse tumbleweed, the laptop most recent update (but no update for couple of weeks).

I'll try to manually find and delete all references of myth under /usr, /lib, etc and recompile. It will take some time, though. JY, I'll attach my mythavutil.cpp, as I think you want?

[yiannividalis@…]

mythavutil.cpp

[JYA]

this is very puzzling..

what linux distribution are you using?

BTW, you have a quad core machine, doing make -j8 here would greatly speed up your compilation time.

so you don't have any binary package of mythtv installed from another source?

[yiannividalis@…]

Replying to jyavenard:

Opensuse tumbleweed on every pc.

BTW, you have a quad core machine, doing make -j8 here would greatly speed up your compilation time.

Yeah, but unfortunately I can only test on the centrino laptop atm because of tv programs the family wants to record on the main system... However I'm using icecream (opensuse's distributing compiler, so the quad core helps somehow)

so you don't have any binary package of mythtv installed from another source?

No, no binaries. I've been running master for more than 5 years now??? (that's a long time!)

Any more info I could provide? any ldd info?

you can do ldd /usr/bin/mythpreviewgen yes

and rpm -qa | grep -i myth while at it...

it's working all fine on my system.

The only difference I can see is that I compile with --compile-type=debug

[JYA]

can you also attach your config.h ?

need to find out why the yadif filter isn't found

[JYA]

one more thing: seeing that you have patched applied.

after doing one last pull

please attach here the result of git diff a05e32711a75de75b4c570a2a36a65f74f2d6797 (which is HEAD in the current master)

thank you

please attach here the result of git diff a05e32711a75de75b4c570a2a36a65f74f2d6797 (which is HEAD in the current master)

I will compile as debug, and we can see what we can arrange for that access after work perhaps? (it's 6.16am now, so it will be some hours before we can arrange that)

Replying to Yianni Vidalis <yiannividalis@…>:

One thing I've not provided yet:

WARNING: --enable-symbol-visibility requires gcc 4.2 or higher

I thought master now requires (at least in theory) a C++11 compliant compiler, which means (at least) gcc 4.3 (for initial support), and in practice, probably 4.8 or greater. What version compiler are you using?

It is entirely possible the gcc version auto-detect is failing too, but would would be a different bug).

Replying to jyavenard: ....

Just an observation, the OP is running a 32-bit system (according to the configure output). I have no idea if that is relevant, but I wonder if any of the people you asked are still running old(er) 32-bit systems that may have different cpu (SSE?) capabilities.

I'm sorry I didn't clarify things enough before:

• All systems at home run opensuse tumbleweed, but at various update stages. The most up to date is the laptop because it's old and not crucial.
• All systems apart from the laptop run 64bit linux, but the laptop can't because the motherboard or stg is 32bit only (I've tried unsuccessfully). It's 10 years old but with an ssd and a brand new fan it doesn't show its age (apart from compile times, that is!)
• as far as the gcc versions are concerned, the MBE has gcc-5-1.23.x86_64, the SBE gcc-4.8-10.1.x86_64, and the laptop gcc-5-1.25.i586. However, I use the icecream package, which is a distcc for opensuse (have been since 4-5 years without any problems) and maybe this is what is causing the "enable symbol visibility" warning (icecream gcc is at that start of $PATH)

  I hadn't noticed at all..

Replying to jyavenard:

Yes, in the gigantic gzip log I've attatched mythpreviewgen.20160225111727.14556.log.gz​) you'll find in line 15304:

At least it's consistent!

Maybe it's an opensuse thing, should I send you the repos I use to add to the image you mentioned you downloaded?

I think I'll dissappoint you further (maybe it's an opensuse thing too...), because by "repos" I don't mean the initial install but the additional repos for multimedia files, e.g. pacman

In case you've not progressed into the downloading, I'd suggest the 64bit, since I have the same problem there, too, and it's more mainstream.

Supposingly, if you download the iso, it chooses a location nearest to you. ​https://en.opensuse.org/openSUSE:Tumbleweed_installation

For pacman, I'd suggest to finish the initial installation and then add the repo. You'll find the link in

​https://en.opensuse.org/Additional_package_repositories

What I do at home is rsync nightly and I've added an nfs share as a repo to the pcs.

Can you take the hit on time and not compile using icecream (distcc). I have seen weird things happen due to distributed compilation.

Lets try a build without it and see how that goes.

so I don't know what you've installed, but I'm 99.9% convinced it's a compilation/installation issue on your end

[Yianni Vidalis <yiannividalis@…>]

Could it be the format of my recordings? I find it difficult to believe that all my systems excibit the same behaviour and it's their own fault. The only thing that's constantly being updated is mythtv. Especially the SBE has not been updated for more than a year. And I didn't have this problem before creating the ticket. Could I ask again to upload a small sample somewhere for you to check? I'm open to suggestions...

[Yianni Vidalis <yiannividalis@…>]

Maybe the prior to ffmpeg 3 installation leaves some garbage I've not been able to remove, even manually? Could you please try to compile and install a previous version and try to upgrade to current commit, then recheck?

doubtful, because once we reach the deinterlacer, we've already decoded the media. So all it sees is a YUV420 picture. it doesn't care if it's h264 or mpeg2 or whatever...

Having said that, if you have a smallish ts file where you can reproduce the problem consistently I could always try with that

Maybe the prior to ffmpeg 3 installation leaves some garbage I've not been able to remove, even manually? Could you please try to compile and install a previous version and try to upgrade to current commit, then recheck?

Myself, I always compile that way:

./configure --prefix=/separate/path

typically I use: ./configure --prefix=/usr/local/mythtv

when to run the code, and ensure nothing else get in the way I run it that way:

LD_LIBRARY_PATH=/usr/local/mythtv/lib /usr/local/mythtv/bin/mythpreviewgen ....

That way I can have a local master build (in /usr/local/mythtv) and the official build (from mythbuntu) is located in /usr/lib

try compiling in a brand new directory, so you know there's nothing getting in the way

otherwise, make sure you do sudo rm /usr/lib/libmyth* before running make install

[Yianni Vidalis <yiannividalis@…>]

I will try it your way, thanks for the tip.

I have a ts file of 50secs and 15Mb. Where should I upload it?

[JYA]

anywhere, public google drive maybe?

Have a read of ​http://lists.mythtv.org/pipermail/mythtv-users/2015-October/382786.html there is a good description on how to keep different versions separate.

excellent thank you.

will try to reproduce it..

it's bizarre, because the stuff generating the string to configure the yadif filters doesn't use locales. plain sprintf.

A big thanks, Jean-Yves.

[JYA]

so I trust it's all working for you now...

[yiannividalis@…]

Yes, everything is ok, sorry for taking so long to reply, I'd been investigating stg else, apparently irrelevant. You fixed it.
