Ffmpeg send duration of video to client (using node-fluent-ffmpeg)
26 mai 2013, par VprnlI'm really new to the world of ffmpeg so please excuses me if this is a stupid queston.
I'm using the module Node-fluent-ffmpeg to stream a movie and convert it from avi to webm with FFMPEG.
So far so good (it plays the video), but I'm having trouble parsing the duration to the player. It also gives me an error even though I plays the video.
my code is as followed :
var stat = fs.statSync(movie);
var start = 0;
var end = 0;
var range = req.header('Range');
if (range != null) {
start = parseInt(range.slice(range.indexOf('bytes=')+6,
range.indexOf('-')));
end = parseInt(range.slice(range.indexOf('-')+1,
range.length));
}
if (isNaN(end) || end == 0) end = stat.size-1;
if (start > end) return;
var duration = (end / 1024) * 8 / 1024;
res.writeHead(206, { // NOTE: a partial http response
'Connection':'close',
'Content-Type':'video/webm',
'Content-Length':end - start,
'Content-Range':'bytes '+start+'-'+end+'/'+stat.size,
'Transfer-Encoding':'chunked'
});
var proc = new ffmpeg({ source: movie, nolog: true, priority: 1, timeout:15000})
.toFormat('webm')
.addOptions(['-probesize 900000', '-analyzeduration 0', '-minrate 1024k', '-maxrate 1024k', '-bufsize 1835k', '-t '+duration+' -ss'])
.writeToStream(res, function(retcode, error){
if (!error){
console.log('file has been converted succesfully',retcode);
}else{
console.log('file conversion error',error);
}
});I set the header with a start and a end based on this article : http://delog.wordpress.com/2011/04/25/stream-webm-file-to-chrome-using-node-js/
I calculate the length in seconds in the variable duration.
The error FFmpeg is giving me is :

Stream mapping:
Stream #0:0 -> #0:0 (msmpeg4 -> libvpx)
Stream #0:1 -> #0:1 (mp3 -> libvorbis)The client side player (which is VideoJs) says the file is infinite/NaN in length.
I feel like I'm pretty close to a solution but my inexperience with the subject matter prohibits me from getting it to work. If I'm unclear in any way please let me know. (I have a tendency of explaining things fuzzy.)
Thanks in advance !
[EDIT]
I removed the duration bit because it has nothing to do with the issue. I checked the response header of the client and saw :
Accept-Ranges:bytes
Connection:keep-alive
Content-Length:13232127
Content-Range:bytes 0-13232127/13232128
Content-Type:video/webmWhy can't the client figure out the duration even though it receives it in the header ?

Revision 53ff43adc3 : Prunes out full-rd computation based on modeled rd Adds a speed feature to elim
9 juillet 2013, par Deb MukherjeeChanged Paths :
Modify /vp9/common/vp9_blockd.h
Modify /vp9/encoder/vp9_onyx_if.c
Modify /vp9/encoder/vp9_onyx_int.h
Modify /vp9/encoder/vp9_rdopt.c
Prunes out full-rd computation based on modeled rdAdds a speed feature to eliminate full-rd computation if the modeled
rd or rd based on a different parameter in the same mode is already
a lot larger than the best rd yet.Specifically, only search the sharp and smooth filters if the modeled
rd cost based on the regular filter is within a certain factor of the
best rd cost so far. Also, skip full-rd computation of non splitmv
inter modes if the modeled rd cost based on pred error is within the
same factor of the best rd cost so far.Also adds some enhancements in the rd search for splitmv mode to
speed things up by early breakouts. Negligible impact on performance.Resuts on derfraw300 :
psnr : -0.013% with the splitmv enhancements, -0.24% with the rd
breakout feature on.
speedup : 6% with splitmv enhancements, 20% with also residual breakout
