  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Videos produced with ffmpeg don't have frame width or height properties ?

    18 mars 2016, par Marie

    I am using the following to produce my intermediate slideshow mp4 clips

    ffmpeg    -r 1 -f image2 -vcodec mjpeg      -i 01.jpg    -i 01.mp3    -codec:v libx264 -r 24    -codec:a copy -b:a 128k    -shortest -y  01.mp4

    And the produced 01.mp4 plays OK however, the properties detail under Windows don’t show any frame size width or height ? Why is that ? This may be an issue, see below...

    I also produced an intro clip in AfterEffect using H.264 to produce an MP4 file.

    I later have problem when I try to concatenate these 01.mp4 ,02.mp4, 03.mp4 with the intro.mp4 using the command line

    ffmpeg -f concat   -i MyFileList.txt  -c copy  -y output.mp4

    The resulting output.mp4 video causes VLC player to crash right after it completes playing the intro segment.
    my xx.jpg files are 1600x1200 and my intro.mp4 is 1920x1080 24fps so perhaps there is an issue there as well.

    I am not able to make sense of the purple and yellow lines from ffmpeg output during the concat perhaps you can help interpret, the output is attached.

    Feel free to change any of the ffmpeg options for the production of my slideshow temp files 01.mp4, .02.mp4, 03.mp4 ... or during the concat operation, it’s been a lot of guess work on my part.

    BTW, the reason I am using concat is because I thought at first ffmpeg would be able to iterate on images 01,02...jpg and matching them up with there 01,02,....mp3 sound files but apparently that is not possible with some command line like this :)

    ffmpeg -i %02d.jpg -i %02d.mp3 .... output.mp4

    Thank you.

  • Long Overdue MediaWiki Upgrade

    5 février 2014, par Multimedia Mike — General

    What do I do ? What I do ? This library book is 42 years overdue !
    I admit that it’s mine, yet I can’t pay the fine,
    Should I turn it in or should I hide it again ?
    What do I do ? What do I do ?

    I internalized the forgoing paean to the perils of procrastination by Shel Silverstein in my formative years. It’s probably why I’ve never paid a single cent in late fees in my entire life.

    However, I have been woefully negligent as the steward of the MediaWiki software that drives the world famous MultimediaWiki, the internet’s central repository of obscure technical knowledge related to multimedia. It is currently running of version 1.6 software. The latest version is 1.22.

    The Story So Far
    According to my records, I first set up the wiki late in 2005. I don’t know which MediaWiki release I was using at the time. I probably conducted a few upgrades in the early days, but that went by the wayside perhaps in 2007. My web host stopped allowing shell access and the MediaWiki upgrade process pretty much requires running a PHP script from a command line. Upgrade time came around and I put off the project. Weeks turned into months turned into years until, according to some notes, the wiki abruptly stopped working in July, 2011. Suddenly, there were PHP errors about “Namespace” being a reserved word.

    While I finally laid out a plan to upgrade the wiki after all these years, I eventually found that the problem had been caused when my webhost upgraded from PHP 5.2 -> 5.3. I also learned of a small number of code changes that caused the problem to go away, thus kicking the can down the road once more.

    Then a new problem showed up last week. I think it might be related to a new version of PHP again. This time, a few other things on my site broke, and I learned that my webhost now allows me to select a PHP version to use (with the version then set to “auto”, which didn’t yield much information). Rolling back to an earlier version of PHP might have solved the problem easily.

    But NO ! I made the determination that this goes no further. I want this wiki upgraded.

    The Arduous Upgrade Path
    There are 2 general upgrade paths I can think of :

    1. Upgrade in place on the server
    2. Upgrade offline and put the site back on the server

    Approach #1 is problematic since I don’t have direct shell access, though I considered using something like PHP Shell. Approach #2 involves getting the entire set of wiki files and a backup of the MySQL tables. This is workable since I keep automated backups of these items anyway.

    In fairly short order, I was able to set up a working copy of the MultimediaWiki hosted on a local Linux machine. Now what’s the move ? The MediaWiki software I’m running is 1.6.10. The very latest, as of this upgrade project is 1.22.2. I suppose it’s way too much to hope that the software will upgrade cleanly from 1.6.x straight to 1.22.x, but I guess it’s worth a shot…

    HA ! No chance. Okay, next idea is to march through the various versions and upgrade each in turn. MediaWiki has all their historic releases online, all the way back to the 1.3 lineage. I decided that the latest of each lineage should upgrade cleanly from anything in the previous version of lineage. E.g., 1.6.10 should upgrade cleanly to 1.7.3 (last in the 1.7 series). This seemed to be a workable strategy. So I downloaded the latest of each series, unpacked, and copied all the wiki files over the working installation and ran ‘php update.php’ in the maintenance/ directory.

    The process is tedious and not without its obstacles. I consider this penance for my years of wiki neglect. First, I run into the “PHP Parse error : syntax error, unexpected T_NAMESPACE, expecting T_STRING” issue, the same that I saw years ago after the webhost transitioned from PHP 5.2 -> 5.3. I could solve this by editing assorted files and changing “Namespace” -> “MWNamespace” (which is what MediaWiki did by version 1.13). But I would prefer not to.

    Instead, I downloaded the source for PHP 5.2 and compiled it in a separate directory, then called ‘/path/to/php/5.2/bin/php update.php’. Problem solved.

    The next problem is that a bunch of the database update scripts are specifying “Type=InnoDB”. This isn’t supported by modern MySQL databases. Now, it’s “Engine=InnoDB”. A quick search & replace at the command line fixes this for 1.6.x… and 1.7.x… and 1.8 through 1.12. Finally, at 1.13, it was no longer necessary. As a bonus, at 1.13, I was able to test the installation since Namespace had been renamed to MWNamespace. I would later learn that the table type modifications probably could have been simplified in by changing “$wgDBmysql4 = true ;” to “$wgDBmysql5 = true ;” somewhere in LocalSettings.php.

    Command line upgrading worked smoothly up through 1.18 series when I got a new syntax error :

    <br />
    PHP Fatal error:  Call to a member function addMessages() on a non-object in /mnt/sdb1/archive/wiki/extensions/Cite.php on line 68<br />

    Best I could do was comment out that line. I hope that doesn’t break anything important.

    In the home stretch, the very last transition (1.21 -> 1.22) failed :

    PHP Fatal error :  Cannot redeclare wfProfileIn() (previously declared in 
    /mnt/sdb1/archive/wiki/includes/profiler/Profiler.php:33) in 
    /mnt/sdb1/archive/wiki/includes/ProfilerStub.php on line 25
    

    Apparently, this problem arises occasionally since 1.18. I found a way around it thanks to this page : Deleted the file StartProfiler.php. Who am I to argue ?

    Upon completing the transition to 1.22, the wiki doesn’t look correct– the pictures aren’t showing up. The solution was to fix the temporary directory via LocalSettings.php.

    Back To Production
    Okay, it all works again ! Locally, that is. How to get it back to the server ? My first idea was that, knowing that this upgrade process can succeed, try stepping through the upgrade process again, but tell the update.php scripts to access the database tables on multimedia.cx. This seemed to be working for awhile, even though the database update phase often took 4-5 minutes. However, the transition from 1.8.5 -> 1.9.6 took 75 minutes and then timed out. According to my notes, “This isn’t going to work.”

    The new process :

    1. Dump the database tables from the local database.
    2. Create a new database remotely (melanson_wiki_ng).
    3. Dump the database table into melanson_wiki_ng.
    4. Move the index.php file out of the wiki files directory temporarily (or rename).
    5. Modify the LocalSettings.php to talk to the new database.
    6. Perform a lftp mirror operation in order to send all the files up to the server.
    7. Send the index.php file and hope beyond hope that everything magically works.

    And that’s the story of how the updated MultimediaWiki came back online. Despite the database dump file being over 110 MB, it only tool MySQL 1m45s to transmit it all to the remote server (let’s hear it for the ‘–compress’ option). For comparison, inserting the tables back into a fresh local database took 1m07s.

    When the MultimediaWiki was first live again, it loaded, but ever so slowly. This is when I finally looked into optimization and found that I was lacking any caching. So as a bonus, the MultimediaWiki should be much faster now.

    Going Forward
    For all I know, I did everything described here in the hardest way possible. But at least I got it done. Unless I learn of a better process, future upgrades will probably look similar to this.

    Additionally, I should probably take some time to figure out what new features are part of the standard MediaWiki distribution nowadays.

  • Appending a list of movies MP4s causes the sound to be dropped or garbled at some point

    9 février 2020, par Marie

    Update I am able to reproduce the issue by concatenating 10 Hello.mp4 clips and see the audio drop out/garbled at about 5 seconds playback. This is via VLC latest 3.0.8 on Windows7 64bit. Window Player zero sound. Media Player Classic it plays fine all 10 audio or the word "Hello". The same movie when dragged onto Whatsapp the PC app plays OK but no sound if played from the Phone Whatsapp. Perhaps its my computer too slow in the production of this clip ??? I don’t know what to trust anymore.

    I copied the same ffmpeg.exe onto my kid’s Windows10 laptop and was able to produce the same behavior with sound dropping out with VLC however Windows10 media player is able to play the audio without a glitch.

    You can reproduce the same on your end with this batch file

    Original Post
    My process is in 3 steps
    Step 1) Corresponding to each bitmap I have 00.JPG ... NN.JPG I combine a list of "SOURCE" mp3 audio into a single audio mp3 to produce matching 00.MP3 ... NN.MP3

    I had glitch here where one my mp3 was not of the correct Sample Rate, however a kind soul in this forum helped me fix that.
    You can read the details here :

    When I append a silent audio (mp3) to an existing list of audio it garbles the final audio ?

    Step 2) combine each mp3 from previous with a the filename matching bitmap to produce a movie .MP4

    IOW,

    • 00.JPG + 00.MP3 >> 00.MP4
    • 01.JPG + 01.MP3 >> 01.MP4
    • and so on

    From this run of 24 subparts, I hand tested some of these movies against Whatsapp and they are accepted fine.
    However, the final MOVIE.MP4 is not.
    I will list below their info from ffprobe.

    Step 3) combine the list of movies from previous into a final MOVIE.MP4
    This is where I have been having random issues typically with audio, currently this audio drops at about 20s from start. Corresponding to roughly movies parts 04.mp4 to 07.mp4

    I play the videos via VLC but Windows Media Player has even worse playback.

    I am able to reproduce Step3 and thus MOVIE.MP4 with following batch file

    rem 10:33 PM 2/6/2020
    SET EXE="S:\_BINS\FFmpeg 4.2.1 20200112\bin\ffmpeg.exe"

    SET ROOTPATH=.\

    SET OUT_FILE="%ROOTPATH%MOVIE.MP4"

    SET IN_FILES_LIST="%ROOTPATH%IN_FILES_LIST.TXT"

    SET OPTIONS= -f concat -safe 0 -i  %IN_FILES_LIST%  -c copy -y  %OUT_FILE%

    SET INFO_FILE="INFO.TXT"

    %EXE% %OPTIONS%  1> %INFO_FILE% 2>&amp;1

    file '01.mp4'
    file '02.mp4'

    I have not been able yet to reproduce the issue with a smaller set of movies, in the meantime if you would to get a copy I would have to upload an archive to a link so you can have them on your side.

    Alternatively, if you would like me to provide additional info from these steps let me know what commands and I will be happy to provide.

    Thank you.
