  • h264_mp4toannexb filter failed to receive output packet while ffmpeg concat

    10 août 2022, par AlexZheda

    I am writing a very easy concat script for a list of videos.

    



    (for %i in (*.mp4) do @echo file '%i') > mylist.txt

    



    ffmpeg -safe 0 -f concat -i mylist.txt -c copy merged.mp4

    



    Yet the log says something weird h264_mp4toannexb filter failed to receive output packet”
Those files are rendered in VLC, but at certain timestamps they start to disallow moving the playtime cursor. I suspect that might be the case but I do not see much from the failed files.

    



    The file(s) it fails on has the following description (ffmpeg -i fn.mp4)
enter image description here

    



    EDIT : Truncated stats from all of the files in order.

  • ffmpeg error in subprocess.run but works in terminal

    6 juin 2023, par 8TM

    I'm creating my own MKV videos and I found a strange bug when I'm using subprocess module from python 3.11.2 to execute FFmpeg command.

    


    My FFmpeg command is running fine in terminal (ends with success) :

    


    ffmpeg -y \
-i input_video_stream.mkv \
-i input_audio_stream_1.ac3 \
-i input_audio_stream_2.ac3 \
-i input_audio_stream_3.ac3 \
-i input_audio_stream_4.ac3 \
-f srt -i input_subtitle_stream_1.srt \
-f srt -i input_subtitle_stream_2.srt \
-map 0 -map 1 -map 2 -map 3 -map 4 -map 5 -map 6 \
-c copy \
-metadata:s:a:0 language=eng -metadata:s:a:0 title="English1" \
-metadata:s:a:1 language=eng -metadata:s:a:1 title="English2" \
-metadata:s:a:2 language=eng -metadata:s:a:2 title="English3" \
-metadata:s:a:3 language=eng -metadata:s:a:3 title="English4" \

-disposition:a:0 default -disposition:s:s:0 default \
output_video_with_audio_and_subtitles.mkv


    


    But when I'm running it by in the same terminal (the same session and the same ffmpeg version) by python from subprocess.run(command) :

    


    subprocess.run([
    'ffmpeg', '-y',
    '-i', 'input_video_stream.mkv',
    '-i', 'input_audio_stream_1.ac3',
    '-i', 'input_audio_stream_2.ac3',

[matroska @ 0x55b3751a1940] Invalid stream specifier : a:0 default.
    Last message repeated 1 times


    


    I know it's reporting something with audio ([matroska @ 0x55b3751a1940] Invalid stream specifier : a:0 default. Last message repeated 1 times) but it's probably problem with my ffmpeg command.

    


  • Attaching audio to video stream using ffmpeg

    5 novembre 2023, par lazarea

    My goal is to build a simple 10-second long video with a grey background, a simple text, and a simple mp3 audio to be played. I believe it should be a simple enough task ; yet, I am unable to get it right, as the audio is not attached to the video stream.

    


    My code is as follows :

    


    import subprocess
from pathlib import Path

folder_path = Path(__file__).parent.absolute()
assert folder_path / "i_have_a_cat.mp3"

ffmpeg_command = [
    'ffmpeg',
    '-y',  # Force override without prompting
    '-f', 'lavfi',
    '-i', 'color=c=gray:s=640x480:d=10',
    '-i', str(folder_path / 'i_have_a_cat.mp3'),
    '-vf', 'drawtext=text=\'I have a cat\':fontsize=24:fontcolor=white:x=(w-text_w)/2:y=(h-text_h)/3*2:enable=\'between(t,2,5)\'',
    '-t', '10',
    str(folder_path / 'output.mp4')
]

subprocess.run(ffmpeg_command)


    


    Checking the ffmpeg logs, I don't see anything extraordinary but I'll paste them here nevertheless because I might be overlooking something.
