• Origin Crusader Media

  14 février 2012, par Multimedia Mike — Game Hacking

  A gleaming copy of the old Origin game Crusader : No Remorse showed up today :

  
  
  

  Immediately, I delved in expecting to find Xan-encoded AVI files that would play perfectly using FFmpeg/Libav. Instead, I found a directory labeled flics/ that indeed has a lot of AVI files, but not in Xan. The programs attempt to interpret them as raw RGB. The strangest thing is the first frame often looks correct, if upside down :

  
  
  

  The first file I peered inside had the video FourCC ‘RRV1′. Searching for this led me to this discussion forum where people have already been hacking on this very format (Origin games invariably get a heap of lasting love). The forum participants have observed that 3 codecs are in play in this flics/ directory, including ‘RRV1′, ‘RRV2′, and ‘JYV1′, which apparently correspond to the initials of certain developers. The reason that the programs identify the files as raw RGB is because the FourCCs don’t appear everywhere that they’re supposed to. Additionally, there are several trailers for other Origin/EA games stored in Cinepak format elsewhere on the disc.

  It seems that I’m the person who added this title to the Xan wiki page, obviously with no first-hand evidence to back it up. Meanwhile, the forum participants speculate that the files are descended from the old Autodesk FLIC format (which would explain why they live in a directory called flics/). Corroborating strings extracted from the CRUSADER.EXE file include “FlicWait”, “FlicPlayer”, “Flic %s not found.”, “flicpath”, and “FLICPLAY.C”.

  The disc also features a sound/ directory which contains AMF files. Suxen Drol already documented these on the wiki as Asylum Media Format files. The disc contains an ASYLUM.DLL file as well as a utility called MOD2AMF.EXE. The latter works beautifully on a random MOD file I had laying around. The AMF file is a bit larger.

  Samples for all 3 FourCCs can be found here, while the AMF files and associated utilities are here.

• FFMPEG ldash 1 low latency option but dash.js not low latency and buggy with lag and start always at 0 cannot control

  7 avril 2021, par Jintor

  I can't figure out how to fix this. playing a supposed low latency mpeg-dash manifest but it's with lots of lag, and play-stop-wait-play-stop-wait....

  


  I have latest ubuntu with latest ffmpeg

  


  here the command

  


  ffmpeg -re -i file.webm -c:v libx264 -preset ultrafast -tune zerolatency -c:a aac -ac 2 -strict -2 -crf 18 -profile:v baseline -maxrate 1000k -pix_fmt yuv420p -bufsize 969k -ldash 1 -streaming 1 -use_template 0 -use_timeline 1 -seg_duration 1 -remove_at_exit 0 -f dash index.mpd


  


  and player side

  


  <code class="echappe-js">&lt;script src='http://stackoverflow.com/templates/account_js/dashjs/dash.3.1.0.min.js'&gt;&lt;/script&gt;&#xA;    
  &#xA;    &lt;script&gt;&amp;#xA;    (function(){&amp;#xA;        var url = &quot;index.mpd&quot;;&amp;#xA;        var player = dashjs.MediaPlayer().create();&amp;#xA;        player.initialize(document.querySelector(&quot;#videoPlayer&quot;), url, true);&amp;#xA;        player.updateSettings({&amp;#xA;            streaming: {&amp;#xA;                 lowLatencyEnabled: true, &amp;#xA;                 liveDelay: 3,&amp;#xA;                 liveCatchup: {&amp;#xA;                    enabled: true,&amp;#xA;                    minDrift: 0.05,&amp;#xA;                    maxDrift: 0,&amp;#xA;                    playbackRate: 0.5,&amp;#xA;                    latencyThreshold: 30    &amp;#xA;                  }&amp;#xA;            }&amp;#xA;        });&amp;#xA;    })();     &amp;#xA;    video = document.getElementById(&quot;videoPlayer&quot;);&amp;#xA;    video.addEventListener(&quot;loadedmetadata&quot;, function(){ video.muted = true; video.play(); }, false);&amp;#xA;    &lt;/script&gt;&#xA;
  

  


  but it's NOT low latency, It forces to start at 0 and cannot control the video

  


  is there a better config setup and what need to be fixed : ffmpeg options or dash.js config

  


• ffmpeg - recode to lower bitrate + remove audio + watermark

  26 avril 2014, par Ove Sundberg

  I’m a complete noob to ffmpeg and I’m trying to do a couple of things in the same call :

  1) recode a video to a lower bitrate

  2) remove audio

  3) add a watermark center bottom

  4) save output as .webm

  With a bit of RTFM and scouring for examples I have managed to achieve of 1, 2 and 4 with :

  ffmpeg -i hires.mp4 -c:v libvpx -crf 10 -b:v 128k -r 24 -an -c:a libvorbis output-file.webm

  This call adds a watermark center bottom :

  ffmpeg -i hires.mp4 -i watermark.png -filter_complex "overlay=main_w/2-overlay_w/2:main_h-overlay_h-10" output-file.webm

  Now I struggle to combine the two. The second -i option is the watermark. Therefore I would have thought that

  ffmpeg -i hires.mp4 -c:v libvpx -crf 10 -b:v 128k -r 24 -an -c:a libvorbis -i watermark.png -filter_complex "overlay=main_w/2-overlay_w/2:main_h-overlay_h-10"  output-file.webm

  would do the trick. It does not off course, the error I get is

  Option b:v (video bitrate (please use -b:v)) cannot be applied to input file watermark.png -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to. Error parsing options for input file watermark.png. Error opening input files: Error number -22 occurred

  So I have the options all messed up. I’ve tried moving the options around but with no luck. I’d really appreciate some help here.
