Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

How to make video (of any format) compatible to play in android's default player ?
24 janvier 2014, par AartiI want to play video urls from server in device's video player,but unable to play all videos
Testing on HTC Desire (4.1.1), Panasonic (4.1.3), Samsung G S2(2.3.6).I've already gone through following links
Sorry, this video cannot be played - streaming mp4 to android and
How to Play Streaming Audio/Video from a url ?
but did not found working solution.I understand few imp things from above,
- Video must be baseline H264 encoded for playing successfully on all devices
- For encoding any kind of video to H264, we need to integret ffmpeg
My questions are,
- How exactly I can convert any format of video to H264 baseline support ? Examples are appreciated.
- Is there any alternate way for FFMPEG ?
- How can I check if video is baseline H.264 ?
I have tried playing videos with both Intent ACTION_VIEW & MediaController, result was same for both.
Its very urgent. Any kind of help or hint appreciated. Thank You.

unwanted bitrate reduction in MOD to mp4 conversion with ffmpeg
18 juillet 2014, par BrianMy Panasonic camcorder records video to a .MOD file.
On Windows... (my linux box currently has network issues :)ffmpeg -i file.MOD
yields
bitrate: 9579 kb/s
video: mpeg2video yuv 420p 704x480 [SAR 10:11 DAR 4:3]
29:97 fps, 29.97 tbr, 90k tbn, 59.94 tbcI tried
ffmpeg -loglevel verbose -i file.MOD file.mp4
ffmpeg -loglevel verbose -i file.MOD -qscale 0 file.mp4
ffmpeg -loglevel verbose -i file.MOD -qscale 1 file.mp4Each of these yields the same bitrate of 2604 and a video codec of h264 (High).
My original file was 22,786 KB and the new files are each 6,217 KB.My goal/purpose is for lossless conversion of the .MOD files for video editing, probably using blender.
So my big question is "How do I do lossless video conversion of .MOD files using ffmpeg to a format that blender and other common video editing tools can work with ?"
But for educational purposes (and posterity) I am also curious why the bitrate is being reduced by the conversions above and why there is no difference when using the -qscale argument.

ffmpeg : Is this a bug in Xcode ?
30 avril 2014, par daozhaoI debug the ffmpeg program on the macosx with xcode.I find a bug with xcode(or lldb)。
code @ ffmpeg_opt.c-->static int open_input_file(OptionsContext *o, const char *filename)
#ifdef DEBUG av_log(NULL,AV_LOG_INFO,"func :%s(%d) filename :%s \n", __func__,__LINE__,filename) ; #endif
if (!strcmp(filename, "-")) //after step over,the debug windows show filename=NULL.
filename = "pipe :" ;#ifdef DEBUG
av_log(NULL,AV_LOG_INFO,"func :%s(%d) filename :%s \n", __func__,__LINE__,filename) ;
//but it can print the correct value。
#endifyou can clone the project from https://github.com/daozhao/FFmpeg.git, and checkout branch(release/2.2withComment) which is include xcode project file. you can debug with
FFmpegMakefile targets
try it.you can see the screen record on https://www.youtube.com/watch?v=3rTLirTGPM4 .
