• ffmpeg : Invalid segment filename template 'stream05d.ts'

  14 juin 2015, par Wildan Muhlis

  I have tried to use http live streaming with ffmpeg windows build (http://ffmpeg.zeranoe.com/builds/)

  Here’s the command

  ffmpeg.exe -v 9 -loglevel 99 -re -i tes.avi -an ^
  
  -c:v libx264 -b:v 128k -preset medium ^
  
  -flags -global_header -map 0 -f segment -segment_time 4 ^
  
  -segment_list test.m3u8 -segment_format mpegts stream%^05d.ts

  but an error message raised,

  [segment @ 045f5840] Codec for stream 0 does not use global headers but container format requires global headers
  
  [segment @ 045f5840] Selected stream id:0 type:video

  What’s this error message mean and how to solve it ?

• Run FFMPEG in an Async Subprocess then Kill after condition complete ?

  16 janvier 2021, par Robert

  I am struggling to get this correct. I have a sample piece of code here :

  


  import asyncio
import signal
import os
from subprocess import PIPE, Popen


async def recScreen():
    cmd = 'ffmpeg -f gdigrab -framerate 30 -i desktop output.mkv'
    process = Popen(cmd)
    await asyncio.sleep(15)
    print("Done sleep")
    process.terminate()
    return 0

loop = asyncio.get_event_loop()
loop.run_until_complete(recScreen())
loop.close()



  


  The whole idea is that, after a condition is met (e.g. sleeping after 15 seconds), we can tell ffmpeg to gracefully stop recording and close.

  


  However, I have yet to find a method that does that. In this example, and most examples using process.terminate() and process.kill(), the process ends abruptly without letting ffmpeg do a clean exit. Attempting to add await to process throws an error since it cannot be awaited.

  


  Using a sample piece like :

  


      process = await asyncio.create_subprocess_shell(
        command, stdout=asyncio.subprocess.PIPE, stderr=asyncio.subprocess.PIPE
    )


  


  and then

  


  await process.terminate()


  


  Throws a NotImplementedError.

  


  I am confused and not sure how I should go about. Does anyone have a solution ?

  


• React Native | FFMPEG on iOS | Adding PNG image overlay "watermark" on a video, JPEG is working, but PNG is not working

  17 mai 2023, par niembro64

  Struggled for five hours so wanted to show people using react-native ffmpeg libraries how to do this.

  


  You need to disable PNG compression in your build settings on XCode.

  


  Follow the description here, I was using a different library but this still worked for me.

  


  disable both of these (set to no)
