  • Upload a LIVE HLS output from FFMPEG to Amazon S3 bucket

    22 janvier 2023, par Pit Digger

    I have an ffmpeg command that outputs live hls stream from a vod file to local disk. I would like to upload the HLS chunks and manifest file in real time to Amazon S3 Bucket. Is it possible to upload it directly from memory ?

    


    Here is the ffmpeg command

    


    ffmpeg -stream_loop -1 -re -i bunny_1080p_30fps.mp4 -c:v libx264 \
-x264opts keyint=30:min-keyint=30:scenecut=-1 -tune zerolatency -s 1280x720 \
-b:v 1400k -bufsize 1400k -hls_start_number_source epoch -f hls stream.m3u8


    


    Note that I have checked all questions here but none of them do that for a live stream and for multiple files output like hls or dash stream.

    


    One option that I have tried is using node-watch module and upload file on change notification, but that does introduce some buffering. But if there was any better option. https://github.com/yuanchuan/node-watch

    cmd code : ffmpeg -i "OPM.mkv" -c:a copy -c:v nvenc_h264 test1.mp4

    and when I used this command

    -crf 18 -preset slow "test1.mp4"

  • Encoding 4K 60Hz lossless from a capture card

    13 décembre 2017, par Alex Pizzi

    Hi all,

    I’m trying to encode 4K 30/60Hz video in a lossless format from a 4K capture card and everything I’ve tried gives me a similar error as in the linked image, [real-time buffer too full or near too full frame dropped]

    [Not mine]
    https://cloud.githubusercontent.com/assets/4932401/22171307/ef5c9864-df58-11e6-8821-4b74ce3f32d0.png

    This is the command I’ve tried most recently :

    ffmpeg.exe -f dshow -video_size 3840x2160 -framerate 30 -pixel_format bgr24 -rtbufsize INT_MAX -i video="MZ0380 PCI, Analog 01 Capture" -vf fps=30 out%d.BMP

    With the images dumped to a 10G RAM disk or 850 EVO. I’m doing this to skip the encoding step.

    I get the same error when encoding with h265 lossless and NVENC h265 lossless.

    I need the video to be lossless as it will be used to test hardware h265 encoders.

    Video source is a 4K Blu-ray.

    Any help would be greatly appreciated. Thank you.
