Librairies et logiciels spécifiques aux médias

10 décembre 2010, par kent1

Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles. Cf. : ce tutoriel ; FFMpeg avec le maximum de décodeurs et (...)

HTML5 audio and video support

13 avril 2011, par kent1

MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...)

Horizontally show two videos side by side and export to one video

15 juin 2015, par Michael Liberman
What I am trying to achieve :
Programmatically (using some kind of script) combine two different videos to one video where the videos are shown side by side and sound from both videos is played simultaneously.

I found at least two ways I could display two videos side by side but in each one I have a different problem that makes it difficult to complete the process :
1. Avisyth and Avs2Avi :
  Avisyth really makes the process easy. With a simple Avisyth script like this you should be able to play two videos side by side :
  
  video1=AVISource("d:\file1.avi")<br /> video2=AVISource("d:\file2.avi")<br /> StackHorizontal(video1,video2)
  
  The creation of a new output file can be done with avs2avi.
  The problem here is that i am not able to play even one avi file with avisyth because I get "AviSource couldn’t locate a decompressor for fourcc xvid" message. I googled for the solutions to that problem but nothing helped. GSpot says that i have all the codecs needed and it seems I can not do anything. Because I can not get to running real videos, I dont know if the final video plays sounds from both videos. Avisyth installed correctly and I am able to run the following script StackHorizontal(version ,version).
2. ffmpeg
  Works like a charm with two videos and the final file BUT i do not get the sounds from both videos but only the first one. I found out that the solution to add sound from the second video will be by using the libfaac in the command line, like that :
ffmpeg.exe -i video1.mp4 -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; movie=video2.mp4, scale=iw/3:ih/3 [right]; [left][right] overlay=main_w/2:0 [out]" -c:a libfaac -b:v 768k Output.mp4

but i always get an error that the encoder libfaac can not be found. I downloaded the libfaac.dll but still no result.

Is there a solution to any of these problems ? Is there another way to programmatically make one video from two videos that are played side by side ? Thanks in advance.

Android YouTube Live v3 rtmp streaming via ffmpeg won't show preview

14 décembre 2017, par Ariel Yust

Hi everyone I’m breaking my head over this issue here,
I’m developing an Android App for streaming content from the user’s device camera (back/front) to a live streaming on YouTube.

Problem :
YouTube Live shows "The health is good." in (Live Streaming->Events) but there’s nothing showing in the preview... in fact when I press play it tells me "An error has occurred, please try again later".

Why is this happening ? what could be the problem ?

What I’m doing :
using google’s Oauth 2.0 and google api for login.
YouTube V3 data api’s for creating a new broadcast and stream or use an opened stream - I’m using RTMP.

I’m opening Camera Api1 and capturing the video into a SurfaceTexture, then I encode images and audio (MIC) using Android’s MediaCodec, save a 3+- seconds *.mp4 file locally and then once the muxer is done I stream the file with ffpmeg.

String[] cmd = {

            "-i", filePath, //local file path (video is playable with vlc)

            "-strict", "experimental",

            "-acodec", "aac",

            "-ac", "1",

            "-ar", "44100",

            "-vcodec", "libx264",

            "-pix_fmt", "yuv420p",

            "-r", "30",

            "-g", "60",

            "-vb", "512k",

            "-profile:v", "main",

            "-preset", "medium",

            "-f", "flv",

            "-s", "1280x720",

            CreateBroadcast.rtmpUrl

        };



ffmpeg.execute(cmd, responseHandler); //responseHandler notify me to send next file



//how I set a new rtmpUrl, in CreateBroadcast.java

rtmpUrl = 

    returnedStream.getCdn().getIngestionInfo().getIngestionAddress() +

    File.separator + 

    returnedStream.getCdn().getIngestionInfo().getStreamName();

ffmpeg - convert movie AND show original input (as resized picture-in-picture, top-left corner) in the final output file

2 octobre 2019, par raven
this is my first post on this forum, so please be gentle in case I accidentally do trip over any forum rules that I would not know of yet :).

I would like to apply some color-grading to underwater GoPro footage. To quicker gauge the effect of my color settings (trial-and-error, as of yet), would like to see the original input video stream as a PIP (e.g., scaled down 50%), in the top-left corner of the converted output movie.

I have one input movie that is going to be color graded. The PIP should use the original as an input, just a scaled-down version of it.

I would like to use ffmpeg’s -filter_complex option to do the PIP, but all examples I can find on "-filter_complex" would use two already existing movies. Instead, I would like to make the color-corrected stream an on-the-fly input to "-filter_complex", which then renders the PIP.

Is that doable, all in one go ?

Both the individual snippets below work fine, I now would like to combine these and skip the creation of an intermediate color-graded video. Your help combining these two steps into one single process is greatly appreciated !

Thanks in advance,
raven.
