  • AWS lambda mp4 thumbnail generator using ffmpeg - incorrect format generated

    10 avril 2021, par sam bhandu

    I am trying to create a thumbnail generator for every mp4 file uploaded to the s3 bucket. I have been following this post published by AWS. The code works fine for the transcoding video file. I changed the code to generate a thumbnail. The code does generate a file but it is an invalid image type.

    


    import json
import os
import subprocess
import shlex
import boto3
import uuid

S3_DESTINATION_BUCKET = "example-bucket"
SIGNED_URL_TIMEOUT = 60

def lambda_handler(event, context):

    # s3_source_bucket = event['Records'][0]['s3']['bucket']['name']
    # s3_source_key = event['Records'][0]['s3']['object']['key']
    # s3_source_basename = os.path.splitext(os.path.basename(s3_source_key))[0]
    # s3_destination_filename = s3_source_basename + "_cfr.ts"
    
    hex_c = uuid.uuid4()
    s3_destination_filename = '/{}/{}.{}'.format('tmp',hex_c, 'jpg')
    s3_client = boto3.client('s3')
    s3_media_url = 'https://s3-us-west-2.amazonaws.com/example-bucket/videos/presentations/testing.mp4'
    ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_media_url + "\" -ss 00:00:02 -vframes 1  \"" + s3_destination_filename + "\""
    # ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_source_signed_url + "\" -f mpegts -c:v copy -af aresample=async=1:first_pts=0 -"
    
    command1 = shlex.split(ffmpeg_cmd)
    p1 = subprocess.run(command1, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
   
    resp = s3_client.put_object(Body=s3_destination_filename, Bucket=S3_DESTINATION_BUCKET, Key='{}{}'.format(hex_c, '.jpg'))
    return {
        'statusCode': 200,
        'body': json.dumps('Processing complete successfully')
    }


    


    Output is as :

    


    {
  "statusCode": 200,
  "body": "\"Processing complete successfully\""
}

  • AWS Lambda : ffmpeg thumbnails Generator : empty JPG

    3 septembre 2020, par Magikey

    When a video is uploaded on S3 i want to store a JPG screenshot.

    



    On a lambda function with amazon AWS, i do :

    



    ...

  let tmpFile = createWriteStream(`/tmp/screenshot.jpg`)

  var ffmpeg = spawn(ffmpegPath, [
      "-ss","00:00:05",
      "-i", target,
      "-vf", "thumbnail,scale=200:200", 
      "-qscale:v" ,"2",
      "-frames:v", "1",
      "-f", "image2",
      "-c:v", "mjpeg",
      "pipe:1"
    ]);

  ffmpeg.stdout.pipe(tmpFile).on("error", err => {
      console.log("Error A: ",err);
    });

  ffmpeg.on('error', err => {
    console.log("Error B", err)
    reject()
  })

  ffmpeg.on('close', code => {
    tmpFile.end();
    console.log('Log A', ffmpeg);

    child_process.exec("echo `ls -l -R /tmp`",
      (error, stdout, stderr) => {
        console.log(stdout)
    });

    resolve()
  })
...


    



    But the result is an empty JPG file in S3.

    



    Logs shows no errors, my "target" is OK, stdout ls show me the empty JPG file.

    



    I have try a lot of things, like use other version of ffmpeg but same.

    



    There is the "console.log('Log A', ffmpeg)" :

  • avcodec_find_decoder for FFMpeg 2.1 is not working with Android

    18 mars 2014, par Fabien Henon

    I ported FFMpeg 2.1 to Android with NDK and I wrote a JNI function to initialize a video.

    Here is the code of this C function :

    JNIEXPORT int JNICALL Java_com_media_ffmpeg_FFMpeg_naInit(JNIEnv *pEnv, jobject pObj, jstring pfilename) {
    
    gVideoFileName = (char *) (*pEnv)->GetStringUTFChars(pEnv, pfilename, NULL);
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "Init %s\n", gVideoFileName);
    

    
    avcodec_register_all();
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "avcodec_register_all\n");
    

    
    av_register_all();
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "av_register_all\n");
    

    
    VideoState *vs;
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "VideoState var\n");
    

    
    vs = malloc(sizeof (VideoState));
    
    memset(vs, 0, sizeof(VideoState));
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "malloc\n");
    

    
    gvs = vs;
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "VideoState\n");
    

    
    //open the video file
    
    avformat_open_input(&vs->pFormatCtx, gVideoFileName, NULL, NULL);
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "open_input\n");
    

    
    //retrieve stream info
    
    avformat_find_stream_info(vs->pFormatCtx, NULL);
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "find_stream_info\n");
    

    
    //find the video stream
    
    AVCodecContext *pcodecctx;
    
    //find the first video stream
    
    vs->videoStreamIdx = -1;
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "before loop\n");
    

    
    AVCodec *pcodec;
    

    
    vs->videoStreamIdx =  av_find_best_stream(vs->pFormatCtx, AVMEDIA_TYPE_VIDEO, -1, -1, &pcodec, 0);
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "after loop. %d\n", vs->videoStreamIdx);
    

    
    //get the decoder from the video stream
    
    pcodecctx = vs->pFormatCtx->streams[vs->videoStreamIdx]->codec;
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "stream selected %d, %d\n", pcodecctx != NULL ? 1 : 0, pcodecctx->codec_id);
    

    
    pcodec = avcodec_find_decoder(pcodecctx->codec_id);
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "find_decoder\n");
    

    
    //open the codec
    
    avcodec_open2(pcodecctx, pcodec, NULL);
    
    __android_log_print(ANDROID_LOG_INFO, TAG, "open2\n");
    

    
    return 0;
    
}

    When I execute this function from my Java code the log find_decoder (after the call to the function avcodec_find_decoder) is never displayed.

    Everything is correct : pointers have correct values and pcodecctx->codec_id has a value equal to 28.
    But when avcodec_find_decoder there is nothing more, like a crash and I have no more log.

    Did I do something wrong when using and initializing FFMpeg ?

    PS : before that instead of a call to malloc, then memset I had a call to av_mallocz but I also had a crash at this point, and replacing this call by malloc and memset fixed the crash.

    EDIT

    I built FFMpeg using this script :
