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 (...)

Supporting all media types

13 avril 2011, par kent1

Unlike 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 (...)

ffmpeg : can options -vf and -vcodec and -acodec be used at the same time ?

9 mars 2016, par TTZ

I am using ffmpeg to generate a video file from a number of images. I need to generate wmv files on Mac, so the -vcodec msmpeg4 -acodec wmav2 options were set.

The video wasn’t in the right dimensions, so I added, -vf scale=512:384. The colleague who received the file could no longer play the video on Windows using Media Player.

Is there a way to fix this ? Could the -vf option co-exist with -vcodec and -acodec ?

Issue when streaming some TV channels threw ffMpeg

7 octobre 2016, par Raphael Serievic

I am trying to stream a TV Tuner feed with ffMpeg through udp.

The ffMpeg command line I use is the following :

ffmpeg.exe -i udp://@239.255.255.9:1234 -map 0:p:1317:0 -profile:v baseline -crf 30 -preset ultrafast -vcodec libx264 -r 25 -vf scale=720:576-b:v 500k -f rtp udp://10.150.112.107:15048/ -map 0:p:1317:1 -acodec pcm_mulaw -strict experimental -ar 8k -ac 1 -b:a 128k -f rtp udp://10.150.112.107:15032/

Where :

1317 is the program id (channel)
10.150.112.107 is where I want to stream the TV channel
239.255.255.9 is where I receive the original TV channel’s feed from my TV Tuner

My problem is that with some program IDs it is working and with some others it is not : it is working with 1572 ("channel 10 hd") but not with 1317 ("7flix Sydney").

The output of this command-line for channel 1572 (where it works) is the following :

C:\Program Files (x86)\Tuner Manager\ServerModule> ffmpeg.exe

 -i udp://@239.255.255.7:1234 -map 0:p:1572:0 -profile:v baseline -crf 30 -prese
