VLC command line : RTSP to mp4 file (video + audio)
8 février 2016, par Dmitriy GerashenkoWin 7 x64.
When I watch this link in VLC player all is fine :
rtsp ://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov
When I try to capture link to file and to display :
- There is video without sound on display.
- Created file is not playable.
Command :
vlc.exe -vvv "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" --sout="#transcode{venc=ffmpeg,vcodec=mp4v,vfilter=canvas{width=800,height=600},aenc=ffmpeg{strict=-2},acodec=mp4a}:duplicate{dst=display,dst=standard{access=file,mux=mp4,dst=video.mp4}"There are some errors in log, for example :
MPEG4GenericRTPSource Warning: Unknown or unsupported "mode": AAC-hbr. Is it cause of my problems ? How to solve my issue ?Complete log (from VLCJ) :

AWS lambda mp4 thumbnail generator using ffmpeg - incorrect format generated
10 avril 2021, par sam bhanduI 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 MagikeyWhen 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)" :
