Convert video to animated GIF with FFmpeg [migrated]
5 janvier 2014, par flexageI have FFmpeg installed and working on my Ubuntu 12.04 LTS Server.
I have managed to successfully automate the process of uploading a video and converting it to both H264/MP4 and OGV for display on the web.
I also wanted to generate an animated GIF thumbnail for the video.
I have got as far as the following, which I'm pretty sure is generating 2 frames a second for the first 10 seconds of the video :
/usr/local/bin/ffmpeg -i "$3/uploads/video-queue/$1.$2" -vf scale=320:-1 -t 10 -r 2 "$3/uploads/video-queue/processing/$1.gif"What I would prefer to do is generate 1 frame every 25 seconds for the duration of the entire video, but also with a maximum number of frames set as something like 50 frames.
I would prefer not to have dependencies on other components such as Image Magik, and I would like to keep this purely shell based.
Thanks in advance ! You guys are way smarter than me for sure !
Here is the complete console output from an ffmpeg run of the command above :

Android FFmpegPlayer Streaming Service onClick notification
8 octobre 2013, par agonyI have a MainActivity class that displays the list of streams available for my project and the StreamingActivity class where the streaming is done.
If the user selected an item from the list it will start the StreamingActivity and start playing the stream.
I'm having trouble to continue streaming music when the user pressed the notification and returning it to the StreamingActivity class if the user pressed or clicked the home menu or when the app goes to onDestroy().I'm using FFmpegPlayer for my project 'coz it requires to play mms :// live streams for local FM station.
Here's my code :

Split Video Files and Make them individually playable
21 juillet 2013, par rashI am newbie to this python. I split webm video file into chunks, but i couldn't able to make them individually playable using python program.But it plays after I join the chunks to a single file. I know its due to the absence of header file. Please help me with the codes to attach the header file to the parts to make them indiviually playable. Please reply. Thanks alot in advance.
Here is the code :
Client side :
import socket, os
import time
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(("localhost", 5005))
size = 1024
while True:
fname = "/home/xincoz/test/conn2.webm"
fn = client_socket.recv(1024)
print fn
fp = open(fname,'wb')
while True:
strng = client_socket.recv(int(fn))
print strng
if not strng:
break
fp.write(strng)
fp.close()
print "Data Received successfully"
exit()Server side :
import os,kaa.metadata
import sys,time
import socket
import Image
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(("localhost", 5005))
server_socket.listen(5)
client_socket, address = server_socket.accept()
print "Conencted to - ",address,"\n"
file = '/home/xincoz/Downloads/connect.webm'
a = kaa.metadata.parse(file)
print '\n Maybe, pending work'
file_name = open(file,'rb')
size=str(os.path.getsize(file))
print size
client_socket.send(str(os.path.getsize(file)))
print file_name
strng = file_name.read(os.path.getsize(file))
client_socket.send(strng[0:2000000])
file_name.close()
print str(a)+"Meta Data"
print "Data sent successfully"
