Cannot create movies

[Karthik]

After installing the application, I am not able to create any movies. It just says forever, the movie is processing.

See the screen shot of the issue.

[Keith Hughitt (keith-hughitt)]

Are any related error logs generated in either <web_root>/log or
/var/log/apache/error.log?

Did you install FFmpeg and x264?

[Karthik (karthikgp)]

I just installed ffmpeg, not x264.

I will install x264 and see what happens.

[Karthik (karthikgp)]

Also, I do not see any error logs generated in <web_root>/log or in /var/log/apache/error.log

[Keith Hughitt (keith-hughitt)]

You may need to enable error logging in PHP. See:
http://wiki.helioviewer.org/wiki/Optimizing_LAMP_(Linux,_Apache,_MySQL,_and_PHP)_for_Helioviewer#General

[Karthik (karthikgp)]

I enabled the logs, however I dont see an log error in folder <web_root>/log or any significant logs in file /var/log/apache/error.log.

I installed ffmpeg and x264 and I still have the same issue.

[Karthik (karthikgp)]

After a day finally I see some message. Movie status is changed from "Processing" to "Error".

See the screen shot attached.

I do not see any significant error log in apache2 error.log file, and I do not see anything in [root folder]/log directory.

[Keith Hughitt (keith-hughitt)]

In the cache directory for a given movie (e.g. cache/movies/.../abc123) there should be a log generated with the command used by FFmpeg. Are those logs there?

If so, what I would try is editing api/src/Movie/HelioviewerMovie.php and temporarily comment out the lines which are responsible for deleting the movie frame after the videos have been generated:

340- // Clean up movie frame images that are no longer needed
341- if (file_exists($dir)) {
342- foreach (glob("$dir*") as $image) {
343: unlink($image);
344- }
345- rmdir($dir);

Then go back and try running the FFmpeg command from the log manually and see if it works.

[Karthik (karthikgp)]

I dont see a directory for movies inside cache directory.

And what is the command used by FFmpeg ?

See the screen shot of folders that I have under /var/www/cache directory.

[Karthik (karthikgp)]

After adding filling in the value for HV_MOVIE_ID_PASS in /var/www/settings/Private.php file with define("HV_MOVIE_ID_PASS", "8sHNa4ju");

I see error message in resque web management for a movie I created.

See attached screen shot of resque web management failed jobs.

[Keith Hughitt (keith-hughitt)]

What permissions do you have for the cache dir? Apache (www-data or httpd) much be able to write there. The easiest way to ensure this is to do a chmod -R 777 cache/, or add www-data to a group with all privileges there.

How did you end up getting Resque web working?

[Karthik (karthikgp)]

See the attached screen shot of permission on cache directory.

I made the permission of webserver to access the entire folder /var/www and earlier I just tried "http://helioviewer.cs.montana.edu:4567/" and it did not work. This is how it was mentioned in the installation wiki (i.e, http://localhost:4567 (replace "localhost" with the hostname for your server when accessing externally). )

However, it worked when I tried "http://helioviewer.cs.montana.edu:4567/resque/"

[Karthik (karthikgp)]

Moreover, for resque setup, I also make these settings

PATH=/usr/local/bin:/usr/bin APP_INCLUDE=/var/www/api/scripts/resque_env.php

 and run these jobs in the background.

QUEUE=on_demand_movie COUNT=5 php /var/www/api/scripts/resque.php &
USER=username PASS=pass /var/lib/gems/1.8/bin/rackup api/scripts/boot.ru &

Please note, in the installation wiki only the job "USER=username PASS=pass /var/lib/gems/1.8/bin/rackup api/scripts/boot.ru" is mentioned. We need to update the wiki with other information as well.

[Karthik (karthikgp)]

Keith,
I am not able to create movies still. I have loaded all the data.

See the screen shot of error details in resque management. It says, "could not find job class Job Moviebuilder"

Karthik

[Karthik (karthikgp)]

Keith,
Do we have any update on this issue ? Please, let me know.

Thanks.
Karthik

[Keith Hughitt (keith-hughitt)]

Karthik,

It is possible that the error you encountered in Resque is due to the workers not be launched with the proper configuration.

Start by killing any workers currently running (you can use "resque list" or "ps -ef | grep resque" to identify them), and then
run the command "APP_INCLUDE=/var/www/api/scripts/resque_env.php QUEUE=on_demand_movie COUNT=1 php /var/www/api/scripts/resque.php" on the command-line. Do not background the job though so you can follow it's output. Also, make sure the paths pointing to resque_env.php and resque.php are correct.

If all goes well the resque worker daemon should start without any errors. If this is the case, now try requesting a movie on Helioviewer and see if the worker on the command-line recieves the request, and if so, any output that is displayed. Also, check the web UI to see if any errors appear there.

Let me know how this goes and we will decide how to proceed from here.

[Karthik (karthikgp)]

Keith,
I killed and started the workers in command line as you mentioned.

See the attached screen shots of the error (in console and in resque web management).

Karthik

[Karthik (karthikgp)]

See the attached screen shot of resque web management display with more detailed error information.

[Karthik (karthikgp)]

Keith, Do we have any updates on this ? Please, let me know.

Karthik

[Keith Hughitt (keith-hughitt)]

Okay, so the workers are at least responding to the jobs now. Next things to check:

1) Does the user running the resque workers have permissions to read/write in cache/movies? You can test this by creating a directory and touching a file in there as the same user.
2) If so, do you see any directories created in the movie cache? e.g. 2013/03/05/xxxyyy/

If the directories do exist, check to see if an ffmpeg.log exists inside. That should provide you with more information. You can also check the main log directory to see if anything is logged there, but In this case I don't think there will be.

If the problem is not a permission error, then I suspect at this point it may be missing codecs (e.g. libx264).

[Karthik (karthikgp)]

Keith,
I ran using my user name, and I do have permission to create directories/files in cache/movies. Also, www-data (web server) also has the read/write access.

Also when I checked the ffmpeg.log I see this command..

ffmpeg -r 15 -i /var/www/cache/movies/2013/03/05/6222Z/frames/frame%d.bmp -r 15 -vcodec libx264 -vpre lossless_fast -metadata title="SDO AIA 131 (2011-03-05 16:33:21 - 17:32:45 UTC)" -metadata artist="Helioviewer.org" -metadata description="The Sun as seen through SDO AIA 131 from 2011 to 03 to 05 16:33:21 to 17:32:45 UTC." -metadata comment="This movie was produced by Helioviewer.org.

However, I could not find the frames directory in the folder /var/www/cache/movies/2013/03/05/6222Z/.

Also, I see permission deny error in the command line ...

k_ganesanpillai@helioviewer:~$ APP_INCLUDE=/var/www/api/scripts/resque_env.php QUEUE=on_demand_movie COUNT=1 php /var/www/api/scripts/resque.php

Moreover, I see this error message in main log directory for Resque log.

Unable to create movie: Error encountered during video encoding. This may be caused
            by a FFmpeg configuration issue, or by insufficient permissions in the cache.

Hope, this provides more information on the issue.

[Karthik (karthikgp)]

Hi Kieth,
Do we have any update on this bug. Kindly, let me know.

Thanks.
Karthik

[Keith Hughitt (keith-hughitt)]

Hi Karthik,

It looks like there is still some underlying permissions issue. It looks like something is still off as far as the permissions go. Using the same user that you are running resque_env as, what happens if you try "mkdir -p /var/www/cache/movies/2013/03/05/6222Z/frames/"?

Another thing you can try to see if this is the issue is to try making the cache directory completely open, e.g.

chmod -R 777 /var/www/cache

[Karthik (karthikgp)]

Hi Keith,
Using the same user name that I use for running resque_env, I tried the command "mkdir -p /var/www/cache/movies/2013/03/05/6222Z/frames/". It created the frames directory in that path successfully.

And also, I changed cache directory to be completely open with the command chmod -R 777 /var/www/cache. However, I still get the error for processing movies.

Karthik

[Keith Hughitt (keith-hughitt)]

Strange. Helioviewer must be attempting to create the directory in the wrong location...

Just to be sure though, can you try creating a test.php script somewhere in your web server with a simple command to create a directory in the cache, e.g.

<?php
mkdir("/var/www/cache/movies/2013/03/05/6222Z/test", 0777, true);
?>

And open it in the web browser. Then check and see if the directory is there (if not, try checking the Apache/PHP error logs to verify that it failed).

If that works, then we Helioviewer is definitely pointing to the wrong location so we need to figure out what is going on.

As a first step, try editing HelioviewerCompositeImage.php and right before the problematic line (436), try adding a print statement to print out $this->_dir.

[Karthik (karthikgp)]

I created the test.php with the command you mentioned and when I open it in a browser, it created a directory in that path specified.

Moreover, with the print command I am seeing this message.

I dont see the frames directory :(, but d222z does exist with the following permissions.

[Keith Hughitt (keith-hughitt)]

Hi Karthik,

To see if the frames directory (and the corresponding frames) are ever created, try editing HelioviewerMovie.php and comment out the "unlink" and "rmdir" lines in the "_cleanUp()" method.

Then try creating a new movie and you will be able to see how far the process gets.

[Karthik (karthikgp)]

Hi Keith,
I commented "unlink" and "rmdir" in the "_cleanUp()" method in HelioviewerMovie.php.

Then, tried to create a movie, however still the same error message as before. See below.

Do you now see a "frames" directory? or is it still not being created?

[Karthik (karthikgp)]

Awesome, yes I see the frames directory and lots of bmp files are in it. See below.

Alright! Now we are getting somewhere!

Now try running the FFmpeg command from the ffmpeg log file in the same movie directory. It will probably fail, but will hopefully tell us something interesting.

[Keith Hughitt (keith-hughitt)]

Ah, I should have guessed it. So the FFmpeg presets are a way to specify a group of settings to apply during encoding to achieve some particular goal (e.g. quality level or file size).

Here is some information about it:

http://wiki.helioviewer.org/wiki/Movie_generation_using_FFmpeg

Can you check to see if you have any .ffpreset files? You can try checking the default locations (e.g. /usr/share/ffmpeg), or using 'sudo updatedb' and 'locate' to look for 'ffpreset'.

Depending on which presets you have available, we can either adjust the relevant settings in Config.ini, or you can copy the presets included with Helioviewer, which are located in "api/resources/FFmpeg/".

[Karthik (karthikgp)]

Hi Keith,
Here is the details on the presets I have now.

k_ganesanpillai@helioviewer:/var/www/cache/movies/2013/04/12/c222Z$ locate ffpreset

I have the following information in Config.ini file on presets, under movie parameters.

x264_preset = "lossless_fast"
x264_hq_preset = "ultrafast"

Let me know, what to do. Thanks.

It looks like FFmpeg may now use the 'avpreset' files provided by the 'libav-tools' package. Try doing another locate for 'avpreset' and see if anything comes up.

Keith,
Nothing comes up for avpreset, when I do a locate avpreset :(

Karthik -- try installing libav-tools:

sudo apt-get install libav-tools

then do a 'sudo updatedb' and try to locate the avpreset files again.
