  arm : hevc_qpel : Fix the assembly to work with non-multiple of 8 widths
  This unbreaks the fate-checkasm-hevc_pel test on arm targets.
  The assembly assumed that the width passed to the DSP functions is
  
  a multiple of 8, while the checkasm test used other widths too.
  This wasn't noticed before, because the hevc_pel checkasm tests
  
  (that were added in 9c513edb7999a35ddcc6e3a8d984a96c8fb492a3 in
  
  January) weren't run as part of fate until in
  
  b492cacffd36ad4cb251ba1f13ac398318ee639a in August.
  As this hasn't been an issue in practice with actual full decoding
  
  tests, it seems like the actual decoder doesn't call these functions
  
  with such widths. Therefore, we could alternatively fix the test
  
  to only test things that the real decoder does, and this modification
  
  could be reverted.

• FFMpeg Upscaling issue

  12 septembre 2020, par user14266881

  Hello so I created a bat file. CMD opens for a quick second and then closes, and if I open it again with the file it generated, it asks me do I want to

  


  

  


  This is the bat file I created.

  


  cd D:\sexy renders\Upscaling
ffmpeg  -i CONVERT.mp4 -vf scale=3840:2160:flags=neighbor -c:v h264_nvenc -profile high -preset slow -rc vbr_2pass -qmin 17 -qmax 22 -2pass 1 -c:a:0 copy -b:a 384k VIDEO.mp4


  


  Also to add, I've went to Advanced System Settings -> Advanced -> Environment Variables -> Path -> New -> D :\sexy renders\ffmpeg\bin

  


• What am I doing wrong ? Tweepy with ffmpeg

  27 août 2020, par pigeonburger

  I'm trying to get this code to pull the media from any tweet that mentions my twitter handle, convert it using ffmpeg via the subprocess module, then send the converted media back to the person as a reply ? Is this all correct ?


  I am also getting an error at tweet_media = clean_data['entities']['media']['media_url'] and I don't understand what I'm doing wrong there (Exception has occurred : TypeError
list indices must be integers or slices, not str
line 32, in on_data
tweet_media = clean_data['entities']['media']['media_url'])

  


  Also is there a better way to use ffmpeg with python that I am not aware of ?

  


  Here is the code I wrote that I'm trying to use :

  


  import tweepy
from tweepy import Stream
from tweepy.streaming import StreamListener
from datetime import datetime
import time
import subprocess

stdout = subprocess.PIPE
def runcmd(cmd):
    x = subprocess.Popen(cmd, stdout=subprocess.PIPE)
    return x.communicate(stdout)

print(" TWITTER BOT")
time.sleep(1.5)
print(" By PigeonBurger, updated 26 August 2020 \n")

import json
import random

class StdOutListener(StreamListener):
    def on_data(self, data):
        clean_data = json.loads(data)
        tweetId = clean_data['id']
        tweet_name = clean_data['user']['screen_name']
        tweet_media = clean_data['entities']['media']['media_url']
        tweet_photo = runcmd('ffmpeg -i tweet_media output.jpg')
        print(clean_data)
        tweet = 'Here ya go'
        now = datetime.now()
        dt_string = now.strftime("%d/%m/%Y %H:%M:%S")
        print(' Reply sent to @'+tweet_name, 'on', dt_string, '\n' ' Message:', tweet, '\n')
        respondToTweet(tweet_photo, tweet, tweetId)

def setUpAuth():
    auth = tweepy.OAuthHandler("consumer_key", "consumer_secret")
    auth.set_access_token("access_token", "access_token_secret")
    api = tweepy.API(auth)
    return api, auth

def followStream():
    api, auth = setUpAuth()
    listener = StdOutListener()
    stream = Stream(auth, listener)
    stream.filter(track=["@YOUR_TWITTER_HANDLE"], is_async=True)

def respondToTweet(tweet_photo, tweet, tweetId):
    api, auth = setUpAuth()
    api.update_with_media(tweet_photo, tweet, in_reply_to_status_id=tweetId, auto_populate_reply_metadata=True, stall_warnings=True)

if __name__ == "__main__":
    followStream()
