The Large Video Upload python script and media_id

[SFrokjaer]

I’m an utter beginner at this, but I seem to have gotten past must hurdles so far but are stumbling at this las one. I am using the exact python script found here https://github.com/twitterdev/large-video-upload-python/ only changing the keys and the file location.

I get the following errors when running the script from a command prompt:

C:\tmp>python async-upload.py
INIT
Traceback (most recent call last):
File “async-upload.py”, line 165, in
videoTweet.upload_init()
File “async-upload.py”, line 52, in upload_init
media_id = req.json()[‘media_id’]
KeyError: ‘media_id’

The video is 720p, 13 seconds long and 1.4 MB, and uploads fine through the web.

What could I be doing wrong?

Are you certain you’ve not accidentally removed any of the code from async-upload.py? In the version on Github, line 52 says:

req = requests.post(url=MEDIA_ENDPOINT_URL, data=request_data, auth=oauth)

The line you’re seeing an error from is the line after that.

If the request is failing or the JSON response from the API is not correct, then I would expect that error to occur (because the media_id value would be missing). You could try tracing out the value of req.json() before the error occurs to see if the API was called successfully.

Hi and thanks for your reply.

Yes I am pretty sure I haven’t changed anything else, I have started over with the original file twice and gotten the same result.

Trace out gave me too much info but I tried pdb and got the below. Is it possible the video isn’t picket up somehow? If I write an incorrect name for the video I get a different error though, so it seems that the script does find the video. But if i write f.ex. ‘C:\tmp\Video.mp4’ in the script I get the following strange error.
OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: ‘C:\tmp\Video.mp4’

Anyway, pdb returned the following from where the video is picked up:

c:\tmp\async2.py(18)()

At a guess I’m going to say that the request is failing for some reason. Try putting pdb.set_trace() right after the line req = requests.post(url=MEDIA_ENDPOINT_URL, data=request_data, auth=oauth) and then test for the value of req.json().

[SFrokjaer]

Thanks, that helped me. I got an 401 error and this led me to figure out that the access tokens had changed, presumably when I was fiddling with access levels one time.

I was hoping I could sneak another question in here.

The upload worked fine with a test video file transcoded in Handbrake, but when it came to test with the live video output from OBS the upload fails due to incompatible format issues both in my script and on web.

My format is mp4, 1920x1080p, 30fps, YUV 4:2:0, 4mbs bitrate, AAC(LC) 48 khz stereo, 14 seconds long, about 6mb big. Seems to be within all requirements I can find.

From a Handbrake version of the file that works.I can obviously see several differences, but I can’t determine if any or which of them are significant.
