• Deploying on google App Engine : An error occurred : ffmpeg was killed with signal SIGABRT Error : ffmpeg was killed with signal SIGABRT

  27 août 2020, par Jérémy Gachon

  I wrote a node-js api, with node-js and fluent-ffmpeg :

  


  'use strict';
require('babel-register');
const path = require('path');    
const ffmpeg = require('fluent-ffmpeg');


  


  [...]

  


  var infs = new ffmpeg

infs.addInput(doc.data().url).outputOptions([
            '-preset slow', '-g 48', '-sc_threshold 0',
            '-map 0:0', '-map 0:1', '-map 0:0', '-map 0:1',
            '-s:v:0 1280x720', '-c:v:0 libx264', '-b:v:0 2000k',
            // "-var_stream_map", "'v:0,a:0 v:1,a:1'",
            '-master_pl_name ./' + req.params.id + '/master' + req.params.id + '.m3u8',
            '-f hls', '-hls_time 6', '-hls_list_size 0',
            '-hls_segment_filename ./' + req.params.id + '/fileSequence|' + req.params.id + '|%d|v%v.ts',
            '-max_muxing_queue_size 1024',
        ]).output('./' + req.params.id + '/video' + req.params.id + '.m3u8')
            .on('start', function (commandLine) {
                console.log('Spawned Ffmpeg with command: ' + commandLine);
            })
            .on('error', function (err, stdout, stderr) {
                console.log('An error occurred: ' + err.message, err, stderr);
            })
            .on('progress', function (progress) {
                console.log('Processing: ' + progress.percent + '% done')
            })
            .on('end', function (err, stdout, stderr) {

                console.log('Finished processing!' /*, err, stdout, stderr*/)
            })
            .run()
        res.status(200).send('GG').end();
    } 
   });


  


  [...]

  


  That work with

  


  


  node app.js

  


  


  on my macbook pro, but when i do

  


  


  gcloud app deploy

  


  


  and I call the public url, I have this logs :

  


  Processing: undefined% done
An error occurred: ffmpeg was killed with signal SIGABRT Error: ffmpeg was killed with signal SIGABRT 


  


  Here is my app.yaml :

  How can I do to deploy correctly my node-js api on google app engine ?

  


  Thank's in advance.

• 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 :

  


  [
    {
        'word': 'This',
        'start': 0.0,
        'end': 0.22,
        'prob': 0.805

    {
        'word': 'is',

    {

    {
        'word': 'words',
        'start': 1.54,
        'end': 1.9,
        'prob': 0.995
    },
    {
        'word': 'does',
        'start': 1.9,
        'end': 2.16,
        'prob': 0.997
    },
    {
        'word': 'not',
        'start': 2.16,
        'end': 2.4,
        'prob': 0.9978
    },
    {
        'word': 'appear.',
        'start': 2.4,
        'end': 2.82,
        'prob': 0.9984
    },
    {
        'word': 'At',
        'start': 3.46,
        'end': 3.6,
        'prob': 0.9793
    },
    {
        'word': 'their',
        'start': 3.6,
        'end': 3.8,
        'prob': 0.9984
    },
    {
        'word': 'proper',
        'start': 3.8,
        'end': 4.22,
        'prob': 0.9976
    },
    {
        'word': 'time.',
        'start': 4.22,
        'end': 4.72,
        'prob': 0.999
    },
    {
        'word': 'Thanks',
        'start': 5.04,
        'end': 5.4,
        'prob': 0.9662
    },
    {
        'word': 'for,
        ',
        'start': 5.4,
        'end': 5.66,
        'prob': 0.9941
    },
    {
        'word': 'watching.',
        'start': 5.94,
        'end': 6.36,
        'prob': 0.7701
    }
]


  


  What could be causing this ?

  


• How to make linker ld find a file ?

  21 avril 2015, par haxan7

  I am cross compiling opencv with FFmpeg and it is throwing the following error :

  /root/work/codesourcery/arm-2013.05/bin/../lib/gcc/arm-none-linux-gnueabi/4.7.3/../../../../arm-none-linux-gnueabi/bin/ld : warning : libavcodec.so.56, needed by ../../lib/libopencv_highgui.so.2.4.10, not found (try using -rpath or -rpath-link)

  I have the libavcodec.so.56, and have put the relevant path to $PKG_CONFIG_PATH.

  doing a pkg-config —list-all | grep avcodec returns

  libavcodec                     libavcodec - FFmpeg codec library

  ls -al libs folder returns

  How can I make the liker find this file ?
