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 :

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 ?

Convert MPEG4 to MPEGTS on Android with FFmpeg
3 juin 2013, par ArdoramorOk, so obviously I know very little to none about ffmpeg API when I made the original post... it is quite overwhelming when one starts learning about digital media and conversion details. After reading quite a bit more and going through ffmpeg source, I was able to get a working output from mp4 to mpegts. The concept is similar to executing :
ffmpeg -i in.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb out.tsBut as I mentioned before, I need to implement it with ffmpeg API in C.
So, although I am able to generate a playable .ts file, its video and audio streams are not synced. That is, playing them back on Android tablet plays the video very slowly while audio is playing at normal speed and then (once audio stream ends) video plays at normal speed to the end. Playing the same generated .ts file in VLC produces a very condensed audio (as though fast-forwarded) and plays video fine.
There are still many aspects of media conversion that I am not familiar with. I am sure that some of them prevent me from successful conversion.
Here is some information (via ffprobe) about the files :
in.mp4 - file generated via Android recording - MPEG4 (H.264 + AAC)
ffmpeg.ts - file generated via ffmpeg conversion - MPEG2TS (H.264 + AAC)
out.ts - file generated via my code - MPEGTS (H.264 + AAC)in.mp4

[/PACKET]As you can see, ffmpeg.ts starts out with video packets that do not have pts/dts. The audio packets that follow contain pts/dts. This repeats until the end. All video packets do not have pts/dts according to ffprobe output.
However, out.ts starts with audio packets and alternate with video packets. Here, video packets also do not have pts/dts. The difference is that here there is one video packet between a series of audio packets. What happened to the rest of the video packets (ffmpeg.ts has 5 audio followed by 5 video).
Obviously, I'm still learning and don't know way too much yet... Does anything jump out as obvious a problem to anyone ? I will greatly appreciate any info / suggestions but will continue to grind at it !!

How to extract subtitles from .wtv file using ffmpeg ?
20 mai 2013, par user1978421does anyone know how to extract subtitles from a wtv file using ffmpeg ?
i have tried many different commands. None of them works.
the closest is this oneffmpeg -i input.wtv -vn -an -codec:s:0 srt test.srtBut it complains Error while encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
what does that really mean ??
