Alert Server Error: global name 'mplayer' is not defined appears when adding a RTSP URL asset.

Good filing. So I guess we have two options available:
The downside with the first option is that we would rely on a completely different software for checking that the feed works (which I presume what the server code does), versus the actual playback. I don't have a super strong option either way, but the second option seems purest, but 'vlc' is likely more limited for these kind of programmatic tasks than 'mplayer'. |

Hi is there an working workaround for this issue? |
|
Good question. I think @nicomiguelino might have temporarily disabled RTSP while debugging video playback on pi 4. In theory it should work but clearly needs more testing. |
|
Actually i have set up an new rpi3B+ with screenly master@f6311f9. And i got the same error message. So i thought it is a bug in the latest version of screenly ose |
|
In mediaplayer.py found i one reference to mplayer? Is there any other reference i didnt see? i changed it to vlc but is gives me the same error as mentioned above. Is the master version using python2.7 or python3.9? |
|
@vpetersson Can you mark this as bug ? |
|
@vpetersson, I think I didn't disable RSTP. RSTP playback isn't working beforehand, even if I add the line |
|
Haven't tried this yet, but we can make use of the VLC Python bindings, If we're to use VLC instead. I did a quick research. Here's a link for reference – https://stackoverflow.com/a/21052684/5114090. |
|
Alright, it shouldn't be that much effort to reinstate RTSP support. For Pi 4, we just need to verify that it works with VLC and it should work out-of-the-box on Pi 1/2/3 with Relevant code: |
|
@vpetersson So to confirm that i understand it correctly. Changing mplayer to omxplayer in Would reinstate RTSP support for PI3 ? In viewer.py is already defined that only model 4B uses VLCMediaPlayer. |
|
It has been a while since I touched this so I think @nicomiguelino simply need to do an audit of all of this before we draw any conclusions. |
|
Hi, is anybody know how to solve this issue? |
|
how i solved the issue:
def view_video(uri, duration):
logging.debug('Displaying video %s for %s ', uri, duration)
media_player.set_asset(uri, duration)
media_player.play()
view_image('null')
timeout = 0
try:
while media_player.is_playing():
watchdog()
sleep(1)
timeout += 1
if timeout > int(duration):
break
except sh.ErrorReturnCode_1:
logging.info('Resource URI is not correct, remote host is not responding or request was rejected.')
media_player.stop()lib/utils.py
def url_fails(url):
"""
If it is streaming
"""
if urlparse(url).scheme in ('rtsp', 'rtmp'):
#run_mplayer = mplayer('-identify', '-frames', '0', '-nosound', url)
#for line in run_mplayer.split('\n'):
# if 'Clip info:' in line:
# return False
return True
"""
Try HEAD and GET for URL availability check.
"""
...Now when I adding rtsp stream in Web interface I am setting checkbox 'Skip asset check' and adding stream works succesfully. |

rtmp://...... link, mplayer gives an error. It does not play streaming video. Could you help |

@lexalexalexa, I just created a new PR (#1890) regarding this matter, but there are still bugs. There is a noticeable transition (black screen) before displaying the videos. Feel free to give comments on the PR, and thanks for your snippet posted months ago. |

Alright. Here's what I have so far... Previously when running scripts on Buster using the 64-bit Lite OS, I had some specific options loaded into a python script which i will share here with details omitted. The options included were -q (for quiet mode) and --no-osd (to hide the IP address upon launch). #!/usr/local/bin/python
from termcolor import colored
import subprocess
import time
import os
# VLC stream URL
rtsp_url = "rtsp://administrator:*******@10.xx.xxx.xxx/rtsp/defaultPrimary-1?streamType=m"
camera_ip = "10.xx.xxx.xxx" # Camera IP address
# Function to start VLC stream
def start_vlc_stream():
subprocess.Popen(["cvlc", "-q", "--no-osd", rtsp_url]) # Include -q flag for quiet mode
# Function to check if camera is reachable
def camera_reachable():
cmd = ["ping", "-c", "1", "-W", "1", camera_ip]
try:
subprocess.check_output(cmd, stderr=subprocess.DEVNULL)
return True
except subprocess.CalledProcessError:
return False
# Function to check if VLC process is running
def vlc_running():
process_name = 'vlc'
cmd = ["pgrep", process_name]
try:
subprocess.check_output(cmd, stderr=subprocess.DEVNULL)
return True
except subprocess.CalledProcessError:
return False
try:
# Main loop to continuously check camera status and VLC stream
while True:
if not camera_reachable():
print(colored("Camera is not reachable. Retrying...",'light_yellow'))
if vlc_running():
subprocess.Popen(["pkill", "vlc"]) # Kill VLC process
print(colored("Stopping VLC...", 'light_red'))
if camera_reachable() and not vlc_running():
print(colored("Camera is reachable. Starting VLC stream...", 'green'))
start_vlc_stream()
time.sleep(10) # Check every 10 seconds
except KeyboardInterrupt:
time.sleep(1)
print(colored("\nScript terminated by user.", 'light_red'))Now when adding those commands into the media_player.py script, I'm getting a black screen, but I am seeing that we do have a connection to the target camera (see below). I'm not sure if this is because I was using CVLC with a dummy interface in my previous script vs Anthias, which I assume is vlc_python, or if it has to do with something else. I'll work on getting Anthias to actually display the rtsp after the connection, but I'm guessing it's the HDMI group/mode, kms/fkms, or interface issues. If anyone has any ideas or would like to point me in the right direction, I would greatly appreciate it. Thanks! media_player.py adjusted [Lines 50-52]: class VLCMediaPlayer(MediaPlayer):
def __init__(self):
MediaPlayer.__init__(self)
options = self.__get_options()
self.instance = vlc.Instance(options)
self.player = self.instance.media_player_new()
self.player.audio_output_set('alsa')
def __get_options(self):
options = []
if lookup_raspberry_pi_version() == 'pi4':
if settings['audio_output'] == 'local':
options += [
'--alsa-audio-device=plughw:CARD=Headphones',
]
options += [
'-q',
'--no-osd'
]
return options |
