Supporting all media types
13 avril 2011, parUnlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...)

Mathematically lossless encoding and decoding of RGB24 image sequence
25 avril 2013, par curryageI am trying to encode a RGB24 image sequence into a mathematically (not merely visually) lossless video. huffyuv was suggested on many online forums so I tried the following.
ffmpeg -i frames\%06d.png -vcodec huffyuv test.avi
The resulting video was then decoded into frames again using ffmpeg
ffmpeg -i test.avi outframes\%06d.png
However, the input and output frames are not bit-by-bit identical as promised by huffyuv here. Any idea how I can accomplish this ? My eventual goal is to read the video file using OpenCV but I am willing to cross that bridge later once I obtain a losslessly encoded video file.
This SO question mentions an attempt to obtain a lossless h264 avi and the summary of responses seems to indicate h264 cannot completely accomplish lossless encoding.
Once again, to emphasize, I am interested in bit-by-bit identical encoding, not just visually similar. Large file sizes are acceptable as is large compression/decompression time.

ffmpeg - i do not add some headers
27 décembre 2020, par badcodeI have compiled the FFmpeg library using : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu


And have built the doc/examples codes and they are working well. There is no problem.


But now I try to add some extra headers to my code


#include "libavformat/avformat.h" // its ok
#include "libavformat/oggdec.h" // fail



but it gives the following error.


No such file or directory
 #include "libavformat/oggdec.h"



And this libavformat dir :


(base) alitokur@ubuntu:~/ffmpeg_sources/ffmpeg/libavformat$ ls | grep ogg
oggdec.c
oggdec.d
oggdec.h
oggdec.o
oggenc.c

oggparsetheora.o
oggparsevorbis.c
oggparsevorbis.d
oggparsevorbis.o
oggparsevp8.c
oggparsevp8.d
oggparsevp8.o



I cant add other headers btw except "avformat.h". What am I missing ?

(Cross-platform) FFMPEG based GUI direct stream copy linear video editor [on hold]
14 octobre 2014, par Fluorescent HallucinogenFFMPEG official site has list of FFMPEG based projects (https://trac.ffmpeg.org/wiki/Projects).
I use VirtualDub for linear video montage using direct stream copy mode (without recompression). It is GNU GPL licensed, but is designed only for Microsoft Windows and operates only AVI files.
FFMPEG is excellent cross-platform utility that supports many formats (codecs and containers). It can be used for split and merge video files (not only AVI) using direct stream copy mode, but FFMPEG is console UI application.
Is there GUI video editor (based on FFMPEG) (cross-platform or maybe only for Linux or maybe only for Windows) that can split and merge video files (not only AVI) using direct stream copy mode and have preview window ?
Now I use video player, watch the input video file, remember the time for split video to fragments and write console line script for merge these fragments. All work is OK, but it is very inconvenient.
At the worst, are there players or editors that can generate project file (that contains time markers for split and merge) that can be used with FFMPEG ?
