That is so helpful, been looking for an efficient way to convert to hls in ffmpeg for a while. Thanks a lot!

It was helpful, thanks a lot!

Thanks a lot!!!

It's useful, and bellow is for live streaming, to covert RTMP to HLS:

ffmpeg -f flv -i "rtmp://server/live/livestream" \
  -map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 \
  -c:v libx264 -crf 22 -c:a aac -ar 48000 \
  -filter:v:0 scale=w=480:h=360  -maxrate:v:0 600k -b:a:0 500k \
  -filter:v:1 scale=w=640:h=480  -maxrate:v:1 1500k -b:a:1 1000k \
  -filter:v:2 scale=w=1280:h=720 -maxrate:v:2 3000k -b:a:2 2000k \
  -var_stream_map "v:0,a:0,name:360p v:1,a:1,name:480p v:2,a:2,name:720p" \
  -preset fast -hls_list_size 10 -threads 0 -f hls \
  -hls_time 3 -hls_flags independent_segments \
  -master_pl_name "livestream.m3u8" \
  -y "livestream-%v.m3u8"

is there any way i can stream the output directly to s3 bucket not in my local ??
it will really helpful.

stderr: More than 1 variant streams are present, %v is expected either in the filename or in the sub-directory name of file pipe:
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

encounter this error

is there any way i can stream the output directly to s3 bucket not in my local ?? it will really helpful.

I would suggest to use Amazon Elastic Transcoder in this case.

• setup/configure preset
• create a pipeline
• upload source video to your S3 bucket
• start the job for selected pipeline and that source video file

https://docs.aws.amazon.com/elastictranscoder/latest/developerguide/getting-started.html

Hi dear when I insert the command

you need to execute that command in one line, or use backslashes at the end of each line
My original command formatted for comfortable viewing. You can replace "new lines" by the space to make it working

thx
