Hi, I'm @chukxoka4, a developer myself. However I am looking for a Python Developer from Romania to fill a Python Full Stack and Python/Scala Backend Developer role. I was hoping I would be able to connect with developers interested in this type of opportunity.

how to give input file of subfolder for ffmpeg.input() on s3 content
eg.
File localtion at s3 bucket is :
abc/video/vid.mp4

video = ffmpeg_streaming.input(s3, bucket_name=SOURCE_BUCKET_NAME, key=key_value)

[aminyazdanpanah]

Try this:

video = ffmpeg_streaming.input(s3, bucket_name=SOURCE_BUCKET_NAME, key="abc/video/vid.mp4")

Might be a silly question, but having to transcode a lot of 4k video for streaming from my Roku channel that I am building. Right now the script is going to take approximately 3.5 hours to transcode 1.18 gb of 4k video to 4k and 1080p HLS. Hoping to speed up the process as I have to transcode about nearly a hundred 4k files. Does the script using hardware acceleration like Nvidia NVENC or is it just using the CPU? Again, probably a silly question, just trying to speed the process up if I can. Let me know what I might do. Thanks, it works great!

Hi @Gaalen69
You can speed up the transcode using Nvidia, I used Tesla T4 GPUs. I tried transcoding 1.5 GB 4K Video in all formats, but it took me approximately 5-10 minutes. For only 1080p, it will take around 4-5 minutes.

Try using the below code,

opts = {
  'hide_banner': None,
  'y': None,
  'vsync': 0,
  'hwaccel': 'cuvid',
  'c:v': 'h264_cuvid'
} 

video = ffmpeg_streaming.input(input_path, pre_opts=opts)
hls = video.hls(Formats.h264("h264_nvenc"),hls_list_size=0, hls_time=2, hls_flags='discont_start+split_by_time')

Hello, my video has different language audio tracks, for example:

video.mp4
video_en.mp3
video_jp.mp3
video_de.mp3

Is there a way to integrate them into one master playlist?
