  • FFmpeg conform DASH to YouTube Live Stream requirements

    4 septembre 2023, par Aniol Pagès

    I'm trying to stream to YouTube using FFmpeg and DASH. I've generated the stream key and I'm successfully sending the generated files to YouTube. However, YouTube refuses the MPD manifest because it has two AdaptationSet (one for video and one for audio), and the documentation specifies that I should use only one for both video and audio

    


    I've tried to use the -adaptation_sets flag unsuccessfully, and also the -map flag.

    


    Here is one of the commands I've tried :
ffmpeg -re -i "/Users/user/Desktop/file.mp4" \        -map 0:v -map 0:a \        -use_template 1 -use_timeline 1 -window_size 5 -min_seg_duration 5000000 \        -f dash dash.mpd

    


    And with the -adaptation_sets flag :
ffmpeg -re -i "/Users/aniolpages/Desktop/2023-09-03 Taller colar filtrar assubtilar.mp4" -map 0 -map 0 -c:a aac -c:v libx264 \ -use_timeline 1 -use_template 1 \ -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -f dash dash.mpd

    


    Has someone been successful to conform the manifest to YouTube requirements ?

    


    Thank you very much !

    


  • MoviePy error : failed to read the first frame of video file... That may also mean that you are using a deprecated version of FFMPEG

    When I run a python telegram bot script locally, it works completely fine but when I run the script on PythonAnywhere I get an error that shows up when I try to generate a video :

    &#xA;

    I tried updating ffmpeg and moviepy. I even tried different versions but to no avail. The video clips are not corrupted as I checked.

    &#xA;

    This part of the code is responsible for generating the videos :

    &#xA;

    def generate_video(audio_path):&#xA;    input_folder = &#x27;/home/AlisterK/video_clips&#x27;  # Replace with your folder path&#xA;    output_file = &#x27;/home/AlisterK/output_combined_video.mp4&#x27;&#xA;    clip_duration = 3  # Duration of each clip in seconds&#xA;    num_clips = 10     # Number of video clips to select and combine&#xA;&#xA;    width = 1080  # Replace with your desired width&#xA;    height = 1920  # Replace with your desired height&#xA;&#xA;    video_clips = random_files_in_folder(input_folder, &#x27;.mp4&#x27;, num_clips)&#xA;&#xA;    clips = [VideoFileClip(os.path.join(input_folder, clip_file)).subclip(0, clip_duration) for clip_file in video_clips]&#xA;    standardized_clips = [clip.resize((width, height)) for clip in clips]  # Ensure consistent resolutions&#xA;&#xA;    final_clip = concatenate_videoclips(standardized_clips)&#xA;&#xA;    final_audio = AudioFileClip(audio_path)&#xA;
