• How to make that video module can generate readable files for the module JW Player ?

  4 janvier 2015, par Dvex

  I use Drupal 7.x with Video Module, Video Pressets for FFMPEG and JW Player.
  I install FFMPEG with this Guide : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu in Ubuntu 14.04

  I’m using jQuery 1.8

  I downloaded the files that the JW Player module requires and renamed some files, as the guide tells me.

  I set the video module so you can use FFMPEG and established the necessary pressets (FLV, MP4 and WebM) for any browser (web and mobile).

  I changed the default settings of these pressets. I put check the option : Force one-pass Encoding. Because if not me error message :

  PHPVideoToolkit error: Execute error. It was not possible to encode "/var/www/html/sites/default/files/private/videos/original/reel para web en loop_2.mp4" as FFmpeg returned an error. Note, however the error was encountered on the second pass of the encoding process and the first pass appear to go fine. The error is with the video codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height".

  When I save a node and add its corresponding video, the module generates the 3 files with their respective formats. But when thrown at the JW Player module, only plays FLV in every browser.
  But not the MP4 or WebM.

  I checked the log and status report and all I get in order.

  So I assume that the MP4 and WebM formats generated are not what the JW Player waiting.

  Does anyone have the solution to this problem ? I tried to recompile FFMPEG with more codecs but it does not solve the problem.

  This is my FFMPEG Configuration :

• Start and end time of MoviePy's VideoClip not working

  21 mars 2024, par ernesto casco velazquez

  I'm trying to add captions to a video. The desired outcome is to show each word in the exact moment is being said.

  


  I have a method that gives me the accurate time start and end per each word :

  


  def get_words_per_time(audio_speech_file):
    model = whisper.load_model("base")
    transcribe = model.transcribe(
        audio=audio_speech_file, fp16=False, word_timestamps=True
    )
    segments = transcribe["segments"]
    words = []

    for seg in segments:
        for word in seg["words"]:
            words.append(
                {
                    "word": word["word"],
                    "start": word["start"],
                    "end": word["end"],
                    "prob": round(word["probability"], 4),
                }
            )
    return words


  


  Then I have a code that uses MoviePy to create TextClip and assing a given start and end time per pair of words (I know there are redundant statements, srry) :

  


  def generate_captions(
    words,
    font="Komika",
    fontsize=32,
    color="White",
    align="center",
    stroke_width=3,
    stroke_color="black",
):
    text_comp = []
    for i in track(range(0, len(words), 2), description="Creating captions..."):
        word1 = words[i]
        if i + 1 < len(words):
            word2 = words[i + 1]
        text_clip = TextClip(
            f"{word1['word']} {word2['word'] if i + 1 < len(words) else ''}",
            font=font,  # Change Font if not found
            fontsize=fontsize,
            color=color,
            align=align,
            method="caption",
            size=(660, None),
            stroke_width=stroke_width,
            stroke_color=stroke_color,
        )
        text_clip = text_clip.set_start(word1["start"])
        text_clip = text_clip.set_end(
            word2["end"] if i + 1 < len(words) else word1["end"]
        )
        text_comp.append(text_clip)
    return text_comp


  


  Finally, I concatenate the words into a single video :

  


  vid_clip = CompositeVideoClip(
    [vid_clip, concatenate_videoclips(text_comp).set_position(("center", 860))]
)


  


  The output is this, but you can clearly see the words are not flowing with the speech. They somehow move faster as if the start/end time did not matter. Here's the video

  


  The words with their respective start/end time, look like this :

  What could be causing this ?

  


• ffmpeg silenceremove - hear what bits are removed

  7 avril 2020, par jimo

  ffmpeg silenceremove is pretty cool. im loving it. i can trim 3 second silences to 2 seconds and reduce a 1.5 hour file of spoken audio down 3 or 4 minutes (depending on the speaker).

  



  once in a while I do hear my choice for stop_threshold (ie-40dB on audio only analog file) does cause the end of a word to be clipped, just here and there when the speaker trails off softly at the end of the word.

  



  is there any way to output what is trimmed to a file ? so I can listen to it and get an idea of just how often this word clipping happens ?

  



  thanks !
