• ffmpeg one draw text to multiple outputs

  31 juillet 2023, par kRicha

  I've created command with ffmpeg-fluent, which connects video file with music, use shortest(video) duration, and output this to result file

  


  const newVideo = Ffmpeg(`./source/video/${category}/${dayNumber}.mp4`)
                .addInput(`./source/audio/${category}.mp3`)
                .addOption([
                    '-map 0:v:0',
                    '-map 1:a:0',
                    '-shortest'
                ]);

            newVideo.videoFilters({
                filter: 'drawtext',
                options: { ...FONT_OPTIONS, ...{ text: '1', boxcolor: 'black@1', y: 280 } }
            }).output('out1.mp4')
                .output('out2.mp4');


  


  generated command line :

  


  ffmpeg \
-i ./source/video/women/1.mp4 \
-i ./source/audio/women.mp3 -y \

-map 0:v:0 \
-map 1:a:0 \
-shortest out2/_.mp4


  


  if I add second output it works, but without audio and drawtext ? How could I fixe this and get draw text works on both outputs

  


• 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.

• passing additional values to s3 event notification for lambda consumption

  8 septembre 2017, par user1790300

  I have to write code in react-native that allows a user to upload videos to amazon s3 to be transcoded for consumption by various devices. For the processing after the upload occurs ; I am reviewing two approaches :

  1) I can use Lambda with ffmpeg to handle the transcoding immediately after the uploading occurs (my fear here would be the amount of time required to transcode the videos and the effect on pricing if it takes a considerable amount of time).

  2) I can have s3 pass an sns message to a rest api after the created event occurs and the rest api generate a rabbitmq message that will be processed by worker that will perform the transcoding using ffmpeg.

  Option 1) seems to be the preferable option based on a completion time perspective. How concerned should I be with using 1) considering how long video transcoding might take as opposed to option 2) ?

  Also, regardless, I need a way to pass additional parameters to lambda or along the sns messaging that would allow me to somehow associate the user who uploaded the video with their account. Is there a way to pass additional text-based values to s3 to pass along to lambda or along sns when the upload completes, as a caveat I plan to upload the video directly to s3 using the rest layer(found this answer here : http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html#RESTObjectPUT-responses-examples) ?
