Configurer la prise en compte des langues
15 novembre 2010, parAccéder à la configuration et ajouter des langues prises en compte

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) (...)

h264 annexb bitstream to flv mux ffmpeg library
20 avril 2015, par Muhammad AliI have an IP Camera which gives H264 annexb Bitstream through SDK calls.
I want to pack this video stream into FLV container. So far I’ve got to know the following :-I have to convert H264 annexb to H264 AVCC :
For this I’ll have to replace NAL header byte (0x00000001) with Size of NALU (big endian format).My question is, What do I do with SPS and PPS ? should I write (av_interleaved_write_frame) them as are after replacing the NAL header ? or do I not write these frames at all ?
I read about AVCC requiring extra data. How do I construct that ? where do I pass that ?

What causes Firefox to refuse playing one specific MP4 that plays well on other browsers, resolution being the only difference ?
3 décembre 2014, par FaroI’m a developer for a PHP powered website that allows the upload of videos which get converted to MP4 using ffmpeg. This setup worked pretty well so far, however today I came across a report of a user that couldn’t play one of the files in Firefox.
I was unable to replicate the issue on my own machine at first, but using a fresh install of Windows 7 I actually got the same issue : The file will not play in Firefox, but works fine in Chrome. If called up directly, Firefox will say "Video can’t be played because the file is corrupt".
When downloaded, Windows will also not create a thumbnail of the video for the file and WMP will only play the audio part.On my own machine the file works perfectly in WMP which made me wonder if it could be a codec issue (I do have the K-Lite Codec Pack installed), however I’ve compared the file to a working one and the only difference is the resolution, filesize and the format profile which is "High@L3.1" for a working file with a 720p resolution and "High@L4.0" for the non-working one (which is 1600x1200).
I then read through the Wikipedia article on H.264/MPEG-4 AVC and began to wonder if the level might be the issue, and the tool I used (XMedia Recode) actually did not allow me to set a height bigger than 1080 on Level 4, however when I set the level to 5 and encoded the file again, it still wouldn’t play.
I did find a note on the MDN page of supported formats which reads :
Firefox/Firefox for Android/Firefox OS supports the format in some cases, but only when a third-party decoder is available, and the device hardware can handle the profile used to encode the MP4.
I’m assuming that is why the codec pack would allow Firefox to play even the ’broken’ file on my machine, I still don’t understand though why Firefox does play some files but not this one, especially when Chrome on the same machine plays all of them.
The line in PHP that starts the conversion is as follows :
exec("/usr/local/bin/ffmpeg '-i' '" . $file_in . "' '-qscale' '4' '-y' '-threads' '1' '-acodec' 'libvo_aacenc' '-vcodec' 'h264' '" . $file_out . "' 2>&1", $buffer, $success);This should produce correct files, and this is indeed the first time a file has issues.
MediaInfo provides this data for the file stream :

Language : EnglishI’ve uploaded a zip with 3 versions of the file, the untouched one, the converted one with the same settings the website would use, and another converted one with level 5.
Maybe I’m missing something obvious, but I couldn’t find anything wrong with it, what do I need to change in order to produce a file that will work natively in Firefox ?
Also, this is my first question on SO, so if you see anything that I can improve, please let me know :-)
