  fftools/ffmpeg : add a function adding a destination filter for InputStream
  This way filtering code does not directly mess with InputStream
  
  internals. Will become more useful in following commits.

• ffmpeg "ignore_loop 0" seems not work on specific gif

  16 mars 2023, par Peter.k

  I use code which worked for every gif I used to embed it within a video :

  


  ffmpeg -i e:\tt121b+.mp4 -ignore_loop 0 -i e:\gals\1\gif.gif -filter_complex "[1:v][0:v]scale2ref=oh*mdar:ih/10[ua][b];[ua]setsar=1,format=yuva420p,colorchannelmixer=aa=0.5[u];[b][u]overlay=(main_w-w)-(main_w*0.1):(main_h-h)-(main_h*0.125):shortest=1" -r 25 -b:v 1500k e:/tt121_logo.mp4


  


  It literally adds an animated image to video on specified place and with chosen size. But when I add a gif which has 180 frames it behaves weirdly. After 15 seconds the gif is looped one, then it stops and the whole video stops but program still codes it to the end but with higher speed. Additionally, the ram is used to the maximum after this breakdown.

  


  What's going on there ? Should I put some additional parameters ? I tried to add -loop 0, -loop 1 in different places and also removed shortest=1 parameter but its either does nothing or the gif have 1 loop and stops.

  


  EDIT

  


  Found the problem. I opened this gif in first found editor and saw that it was not saved as looped infinitely. Saved it in that format and it works. Didn't know the ffmpeg -loop parameters don't make it. However, this unlooped gif worked as looped in preview software to add more mess to the topic.

  


• How do I fix this error in Python : RuntimeWarning : Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

  11 mars 2023, par Mason Griffith

  I have been trying to mess around with some of Eleven Labs API and make a simple program that takes in a string and can use the API to retrun a voice provided by Eleven Labs speaking the string. I've seen people using similar code to this but I always get the same error telling me it couldnt find ffmpeg or avconv. Any help would be grealty appreciated. Here is the code below.

  


  from elevenlabslib import *
import pydub
import pydub.playback
import io


def play(bytesData):
    sound = pydub.AudioSegment.from_file_using_temporary_files(io.BytesIO(bytesData))
    pydub.playback.play(sound)
    return


user = ElevenLabsUser("API_KEY")  # fill in your api key as a string
voice = user.get_voices_by_name("Rachel")[0]  # fill in the name of the voice you want to use. ex: "Rachel"
play(voice.generate_audio_bytes("Test"))  # fill in what you want the ai to say as a string


  


  Ive downloaded all the suggested packages and downloaded ffmpeg for windows but nothing has worked yet. I can see that the request is going through to the Eleven Labs website as my requested string pops up in my history on Eleven Labs but because of the error no audio is returned.
