Xuggle mp4 output (isom mp41 codec ?) issues
19 mai 2017, par JonSidesWe’re using Xuggler to create an mp4 from pictures, with no audio at this point. The mp4 we’re getting is playable locally, but cannot be embedded in a webpage or chromecast. I suspect the issue is that we’re getting an older ISOM mp41 codec that’s not supported by HTML5 and chromecast. That’s a guess based on this snippet of header info :
Internet media type : video/mp4
Codec ID : isom
Codec ID : isom (isom/iso2/mp41)
Codec ID/Url :
http://www.apple.com/quicktime/download/standalone.html
CodecID_Compatible : isom/iso2/mp41
Codec : MPEG-4
Codec : MPEG-4
Codec/Extensions usually used : mov mp4 m4v m4a m4b m4p 3ga 3gpa
3gpp 3gp 3gpp2 3g2 k3g jpm jpx mqv ismv isma ismt f4a f4b f4vI can embed and chromecast mp42 type files. So the first part of my question is Am I on the right track in looking at isom and mp41 ? And if so, can I get Xuggler to output using a newer codec ?
I can post the full header if that would be helpful.
The above snippet is from mediainfo. Here’s the whole thing, which is too long for a comment :

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"
