Two questions.
1) I'm trying to make my video's thumbnail a snapshot of a particular time in the video (2 seconds in). But, after following the instructions found at this link, when I run the following code, the thumbnail does not change, and the array is empty. I've tried different time formats, but not sure which is right. Any suggestions on what might going wrong?
https://developer.vimeo.com/api/playground/videos/%7Bvideo_id%7D/pictures
2) Is it possible to just upload the actual thumbnail file via the API?
$video_data = $lib->request('videos/107110137/pictures', array('time' => '00.02'), 'POST');
echo '<p>video_data after thumb change is <pre>';
print_r($video_data);
//Prints out
Array
(
[body] =>
[status] => 0
[headers] => Array
(
)
)
Thanks!
A status code of 0 means that curl was unable to reach the API servers.
The most common issue that leads to a 0 status code is HTTPS certificate problems. Take a look at http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/. I do NOT recommend their quick fix, because it will leave you more vulnerable to man in the middle attacks
If that doesn't work, add a curl_error check to the _request function to find out more.

Good day. I apologize for asking for obvious things because I'm writing in PHP and I know Python at the level "I started learning this yesterday". I've already spent a few days on this - but to no avail.
I downloaded twisted example of the SSH server for version 20.3 from here https://docs.twistedmatrix.com/en/twisted-20.3.0/conch/examples/. Line 162 has an execCommand method that I need to implement to make it work. Then I noticed a comment in this method "We don't support command execution sessions". Therefore, the question: Is this comment apply only to the example, or twisted library entirely. Ie, is it possible to implement this method to make the example server will work as I need?
More information. I don't think that this info is required to answer my questions above.
Why do I need it? I'm trying to compile an environment for writing functional (!) tests (there would be no such problems with the unit tests, I guess). Our API uses the SSH client (phpseclib / SSH2) by 30%+ of endpoints. Whatever I do, I had only 3 options of the results depending on how did I implement this method: (result: success, response: "" - empty; result: success, response: "1"; result: failed, response: "Unable to fulfill channel request at… SSH2.php:3853"). Those were for an SSH2 Client. If the error occurs (3rd case), the server shows logs in the terminal:
[SSHServerTransport, 0,127.0.0.1] Got remote error, code 11 reason: ""
[SSHServerTransport, 0,127.0.0.1] connection lost
I just found this works:
def execCommand(self, protocol, cmd):
protocol.write('Some text to return')
protocol.session.conn.sendEOF(protocol.session)
If I don't send EOF the client throws a timeout error.
I'm currently using Javascript to upload some video files to S3. The process works for files <100MB, but for ~100MB plus on chrome I run into an error (this works on safari). I am using ManagedUpload in this example which should be doing multipart/form-data in the background.
Code snippet:
...
let upload = new AWS.S3.ManagedUpload({
params:{
Bucket: 'my-bucket',
Key: videoFileName,
Body: videoHere,
ACL: "public-read"
}
});
upload.promise();

Chrome crashes with the error RESULT_CODE_INVALID_CMDLINE_URL, dev tools crash and in the Chrome terminal logs i get this:

I've tried using HTTP PUT also, both work for smaller files but once i get bigger they both crash.
Any ideas? I've been through tons of SO posts / AWS docs but nothing helped this issue yet.
Edit: I've filed the issue with Chrome; seems like its an actual bug. Will update post when I have an answer.
This issue came from loading the big file into memory (several times) which would crash chrome before it even had a chance to upload.
The fix was using createObjectURL (a url pointing to the file) instead of readAsDataUrl (the entire file itself), and when sending the file to your API, use const newFile = new File([await fetch(objectURL).then(req => req.blob()], 'example.mp4', {type: 'video/mp4'});
This worked for me as I was doing many conversions to get readAsDataUrl to the file type i wanted, but in this way i use much less space.
===SIMPLE & SHORT===
Does anybody have working application that talks with Poloniex through WAMP in these days (January, 2018)?
===MORE SPECIFIC===
I used several info sources to make it work using combo: autobahn-cpp & C++. Windows 10 OS.
I was able to connect to wss://api.poloniex.com, realm1. Plus I was able to subscribe and get subscription ID. But I never got any events even when everything established.
===RESEARCH===
During research in the web I saw a lot of controversial information:
1. Claims, that wss://api2.poloniex.com should be used, and channels names are actually numbers - How to connect to poloniex.com websocket api using a python library
2. This answer gave me base code, but I am getting anything more than just connections, also by following this answer - wss://api.poloniex.com is correct address - Connecting to Poloniex Push-API
3. I saw post (sorry, lost the link), there were comments made that websockets implementation are basically broken on poloniex. They were posted 6 months ago.
===SPECS===
1. Windows 10
2. Autobahn-Cpp
3. wss://api.poloniex.com:443 ; realm1
4. Different subscriptions: ticker, BTC_ETH, 148, 1002, etc..
5. Source code I got from here
===WILL HELP AS WELL===
Is there any way to get all valid subscriptions or, probably, those, that have more than 0 subscribers? I mean, does WAMP have a way to do that?
Is there any known issues with Autobahn-Cpp and poloniex combo?
Is there any simpler way to test WAMP elsewhere to make sure Autobahn isn't a problem? Like any other well documented & supported online projects that accept WAMP websocket communication?
I can receive the correct tick order book data from wss://api2.poloniex.com use python3
but sometime The channel 1002 may stop sending the new tick info.
wss://api.poloniex.com:443 ; realm1
This may be the issue as I've been using api2 and here is the code that works, and has been working for the past 2 quarters non-stop. Its in python, but should be easy enough to port to C++.
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import websocket
import json
def on_error(ws, error):
print(error)
def on_close(ws):
print("### closed ###")
connection.close()
def on_open(ws):
print("ONOPEN")
ws.send(json.dumps({'command':'subscribe','channel':'BTC_ETH'}))
def on_message(ws, message):
message = json.loads(message)
print(message)
websocket.enableTrace(True)
ws = websocket.WebSocketApp("wss://api2.poloniex.com/",
on_message = on_message,
on_error = on_error,
on_close = on_close)
ws.on_open = on_open
ws.run_forever()
the code is pretty much self-explanatory (You can check all channels/pairs on Poloniex API website), just save it and run in terminal
python3 fileName.py
should provide You with BTCETH raw stream of orders and trades on console output.
Playing with the message/subscriptions You can then do as You please with it.
It seems that websockets in Poloniex are unstable. Therefore I can stop my attempts make Autobahn-Cpp work with it at least by now and move on.
I tried creating a simple libtorrent python client (for magnet uri), and I failed, the program never continues past the "downloading metadata".
If you may help me write a simple client it would be amazing.
P.S. When I choose a save path, is the save path the folder which I want my data to be saved in? or the path for the data itself.
(I used a code someone posted here)
import libtorrent as lt
import time
ses = lt.session()
ses.listen_on(6881, 6891)
params = {
'save_path': '/home/downloads/',
'storage_mode': lt.storage_mode_t(2),
'paused': False,
'auto_managed': True,
'duplicate_is_error': True}
link = "magnet:?xt=urn:btih:4MR6HU7SIHXAXQQFXFJTNLTYSREDR5EI&tr=http://tracker.vodo.net:6970/announce"
handle = lt.add_magnet_uri(ses, link, params)
ses.start_dht()
print 'downloading metadata...'
while (not handle.has_metadata()):
time.sleep(1)
print 'got metadata, starting torrent download...'
while (handle.status().state != lt.torrent_status.seeding):
s = handle.status()
state_str = ['queued', 'checking', 'downloading metadata', \
'downloading', 'finished', 'seeding', 'allocating']
print '%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s %.3' % \
(s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \
s.num_peers, state_str[s.state], s.total_download/1000000)
time.sleep(5)
What happens it is that the first while loop becomes infinite because the state does not change.
You have to add a s = handle.status (); for having the metadata the status changes and the loop stops. Alternatively add the first while inside the other while so that the same will happen.
Yes, the save path you specify is the one that the torrents will be downloaded to.
As for the metadata downloading part, I would add the following extensions first:
ses.add_extension(lt.create_metadata_plugin)
ses.add_extension(lt.create_ut_metadata_plugin)
Second, I would add a DHT bootstrap node:
ses.add_dht_router("router.bittorrent.com", 6881)
Finally, I would begin debugging the application by seeing if my network interface is binding or if any other errors come up (my experience with BitTorrent download problems, in general, is that they are network related). To get an idea of what's happening I would use libtorrent-rasterbar's alert system:
ses.set_alert_mask(lt.alert.category_t.all_categories)
And make a thread (with the following code) to collect the alerts and display them:
while True:
ses.wait_for_alert(500)
alert = lt_session.pop_alert()
if not alert:
continue
print "[%s] %s" % (type(alert), alert.__str__())
Even with all this working correctly, make sure that torrent you are trying to download actually has peers. Even if there are a few peers, none may be configured correctly or support metadata exchange (exchanging metadata is not a standard BitTorrent feature). Try to load a torrent file (which doesn't require downloading metadata) and see if you can download successfully (to rule out some network issues).
Whee first question! hi5
So, I have my own version of the Phenny python IRC bot (https://github.com/sbp/phenny). What I'm trying to do is have phenny query the IRC server for a list of nicks who are in a given channel.
I know (from looking at some of phenny's modules) that I can query the server using the following command:
phenny.write(['NAMES'], channel)
Where I'm having trouble is in getting the response from the server and parsing it into a list of nicks. I recognize that the answer I want is probably in the bot.py or irc.py phenny modules, but I've only been writing Python for about 2 months and can't quite get my mind around it.
Any help would be appreciated, thank you!!
OK, so I found a way to do it, which (mostly) works.
I have a routine which triggers on a '353' event, which is how the server responds to /NAMES commands. It stores the list of nicks into a shelve db, indexed by channel.
def nametrigger(phenny, input):
names = re.split(' ', input)
names = [n.split('!')[0] for n in names]
names = [n.replace('~','') for n in names]
namesdb = shelve.open(phenny.logdir+'/nicks')
namesdb[input.args[2]] = names
namesdb.close()
nametrigger.event = '353'
nametrigger.rule = '(.*)'
nametrigger.priority = 'high'
I wrote some utility commands to call /NAMES whenever joining a channel, and whenever someone else joins, leaves, or changes nicks. That should keep the db up to date, though it doesn't seem to work 100% yet.
Then, whenever I want the list of nicks, I can just load the db.
