Python Lambda function and ffmpeg command with stdout from jpg to ts file
28 juillet 2021, par SflaggI have a AWS Lambda Python function setup to process jpg and convert it to a ts file.


I followed these instructions https://aws.amazon.com/blogs/media/processing-user-generated-content-using-aws-lambda-and-ffmpeg/ but changed the command from vfr to cfr conversion to a jpg to ts conversion.


This is the command I am using


ffmpeg_cmd = "/opt/bin/ffmpeg -r 30000/1001 -loop 1 -i \"" + s3_source_signed_url + "\" -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=48000 -t 30 -vcodec libx264 -crf 23 -s 1920x1080 -r 30000/1001 -g 150 -pix_fmt yuv420p -acodec aac -b:a 96k -ar 48000 -"


Everything else is basically the same from the AWS article besides having s3 triggers in my Lambda look for jpeg and jpg suffixes.


But this results in 0 byte ts file.


I have a hunch that I need to modify the command that has a seekable output format (e.g. mpegts) when writing to stdout ; currently my command is likely not working for stdout and that is why I get an empty ts file. But I am having trouble formatting the command correctly. Any help with this would be greatly appreciated !

Creating Thumbnails From Ffmpeg Hangs Php
30 octobre 2012, par Piyush AroraI have been working on a php webservice, which receives videos(uploaded) from iphone and upload them to Amazon cloudFront. After uploading videos, I need to generate thumbnails for video from the Amazon link generated. I am using ffmpeg with
shell_exec
command for it. Here is the code for the same :public function createThumbnail($userId,$fileUrl,$imageName){
//$imageUrl = 'http://184.168.116.177:81/json_api/json/bin/';
if(!is_dir("images/".$userId)){
mkdir("images/".$userId);
}
// path of installed ffmpeg
$ffmpeg = $_SERVER['DOCUMENT_ROOT'] .'bin/ffmpeg';
$cmd = "$ffmpeg -itsoffset -1 -i $fileUrl -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 images/".$userId."/".$imageName;
shell_exec($cmd);
return "images/".$userId."/".$imageName;
}The above code generates the thumbnail, but script does not execute after shell_exec command. So, there is no response sent to iphone end about the thumbnail link. This function works well video is uploaded from web browser of pc. If I comment, shell_exec command, then response is sent to iphone end, but obviousely image is not created.
Thanks in advance.
