Thanks. I believe the time-limiting problem was the wav file (as bpa
suggested). I am, coincidentally, also trying flac as I write, my
script now as below. I'm passing some environment variables so I can
ensure squeezelite and the python program do the same thing. So far
with this version the first time I tried to connect it appeared to
succeed but didn't play, but from then on it's been flawless. However,
I have to wait an hour or more on my test system to know if it's going
to stop, which limits my testing opportunities. What problems do you
get that cause it to fail?
It seems a bit silly to get my flacs converted to raw in squeezelite,
and back to flac again, but never mind. If LMS had a 'stream.flac' as
well as a 'stream.mp3' all this would be unnecessary, but I guess that's
a wish too far!
Python - playstreamMarantz (a symbolic link to the python program so I
can have multiple distinguishable copies) - a version using 'chunked'
output - change the HOST for your system:
Code:
--------------------
#!/usr/bin/python
import BaseHTTPServer
import SocketServer
import subprocess # For running sox
import sys # For writing to stderr
import os # For environment
variables
PORT = int(os.environ.get('VBPORT'))
HOST = "192.168.1.10"
BITRATE = int(os.environ.get('BITRATE'))
DEPTH = int(os.environ.get('DEPTH'))
MIMETYPE = 'audio/flac'
BUFFER = 65536
class Handler(BaseHTTPServer.BaseHTTPRequestHandler):
def do_HEAD(s):
sys.stderr.write (str(s.client_address) + str(', ') + str(s.path) + str(', ')
+ str(s.command) + '\n')
s.send_response(200) # OK
s.send_header('Content-Type', MIMETYPE) # Wav
s.send_header('Content-Length', '0') # length unknown
s.send_header('Transfer-Encoding', 'chunked') # Chunked
s.end_headers()
def do_GET(s):
s.do_HEAD() # Send the headers
# Use flac to transform raw data to flac, using the environment variables for
bitrate and depth (bits)
pa = subprocess.Popen('flac - -c --channels 2 --bps ' + str(DEPTH) + '
--sample-rate ' + str(BITRATE) + ' --endian little --sign signed --fast', shell
= True, bufsize = BUFFER, stdout = subprocess.PIPE)
# Loop until no data, reading and writing
while True:
data = pa.stdout.read(1024)
if len(data) == 0: break
s.wfile.write('%X\r\n%s\r\n'%(len(data), data))
# Done. Send null chunk
s.wfile.write('0\r\n\r\n')
sys.stderr.write(str('stream closed') + '\n')
# Allow the port to be re-used. If there's a failure but the client keeps
the port open, restarting the server can fail
# unless this is set.
SocketServer.TCPServer.allow_reuse_address = True
httpd = SocketServer.TCPServer((HOST, PORT), Handler)
sys.stderr.write(str('listening on port ') + str(PORT) + '\n')
# And now do the above
try:
httpd.serve_forever()
# Close if run from terminal and closed, or a sigkill/term is received.
except (KeyboardInterrupt, SystemExit):
pass # Nothing
httpd.server_close()
