Creating farms of unique websites

This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

FFMPEG - Converting any kind of file to Mp4 compatible with IOS and Flash
5 février 2013, par arashagaI am struggling with FFmpeg whithing Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
I have used the following commands so far, please note that the variables starting with " !" are placeholders and will be replaces with the proper items :FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile
FFmpeg -strict experimental -y -i !videofile -pass 2 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -acodec aac -ab 128k !convertfileThe above command produce an error as :
error executing command for rendering preset HTML5 MP4, command #1 :

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'.Another command that I used is :
FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile
FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfileOutput for the first pass :

GStreamer with MPEG-TS Video4Linux ATSC/DVB Recording
21 juin 2013, par Dustin OpreaI'm having an impossible time setting up a filtergraph to read from a recording that I made from my DVB video4linux device. Any help would be vastly appreciated.
How I made the recording :
To tune the channel :
azap -c ~/channels.conf "Florida"To record the channel :
cat /dev/dvb/adapter0/dvr0 > /tmp/testThis is the way that recordings must be made (I can not use any GST DVB plugins to do this for me).
I used tstools to identify that the recording is a TS stream :
tstools/bin$ ./stream_type ~/recordings/20130129-202049
Reading from /home/dustin/recordings/20130129-202049
It appears to be Transport Stream...but that there are no PAT/PMT frames :
tstools/bin$ ./tsinfo ~/recordings/20130129-202049
Reading from /home/dustin/recordings/20130129-202049
Scanning 10000 TS packets
Found 0 PAT packets and 0 PMT packets in 10000 TS packetsI was able to produce a single ES (elementary stream) stream, by running ts2es :
tstools/bin$ ./ts2es -pid 97 ~/recordings/20130129-202049 ~/recordings/20130129-202049.es
Reading from /home/dustin/recordings/20130129-202049
Writing to /home/dustin/recordings/20130129-202049.es
Extracting packets for PID 0061 (97)
!!! 4 bytes ignored at end of file - not enough to make a TS packet
Extracted 219258 of 248113 TS packetsI am able to play the ES stream (even though the video is frozen on the first frame) :
gst-launch-0.10 filesrc location=~/recordings/20130129-202049.es ! decodebin2 ! autovideosink
gst-launch-0.10 filesrc location=~/recordings/20130129-202049.es ! decodebin2 ! xvimagesink
gst-launch-0.10 playbin2 uri=file:///home/dustin/recordings/20130129-202049.esNo matter what I do, though, I can't get the original TS file to open. However, it opens in Mplayer/FFMPEG, perfectly (but not VLC). This is the output of FFMPEG :

ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...It fails [probably] because no PID has been specified with which to find the video (the "EOS" error, I think).
Naturally, I tried the following to start by demuxing the TS format. I believe it's the "es-pids" property that receives the PID in the absence of PMT information (which tstools said there weren't any, above), but I tried "program-number", too, just in case. gst-inspect indicates that one is hex and the other is decimal :

I don't understand this, since I haven't even picked a PID yet.
What am I doing wrong ?

audio extracted from flv file via ffmpeg is of shorter duration than the actual flv video [closed]
11 janvier 2013, par user1961143I have extracted audio from flv file via ffmpeg using this command :-
ffmpeg -i 164_29.flv v19.mp3
The flv videos duration is 3 minutes but the audio is of 2 mins 20 seconds only. On searching i found that the silent pieces of audio are removed when generating audio from ffmpeg. But i need the audio file to be of exactly same duration as flv video as later i need to put this audio in the flv video itself. Please help as this is urgent for our project. I am running the FFMpeg via .net windows service, so in case you know any other tool which can extract the audio of same duration as video and can be run via .net, it would be useful too.

At least one output file must be specifiedIf you see the duration of video is of 3:04 but audio extracted from it is of 2:25 only.
Actually i am using ffmpeg overlay to show two videos side by side in our debate project for the client. Now ffmpeg takes audio from first video by default. But we want the audio from both videos together as a debate going on. Hence I thought of a solution to extract audio from both videos and merge them and than apply them to the overlayed video. This will all work perfectly only if I get the complete audio from the video file i.e. of equal duration.
For more information i am writing here the overlay command we are using :-**ffmpeg -i 164_29.flv -vf "[in] scale=359:320, pad=2*iw+6:ih
[left]; movie=164_30.flv, scale=359:320 [right]; [left][right]
overlay=365:0 [out]" -b:v 3600k -y a1.flv**
**This is the console output of this overlay command:-**C :\Users\ritika.thakur>ffmpeg -i 164_29.flv -vf "[in] scale=359:320, pad=2*iw+6
