  • ffmpeg - how to pass all streams audio/tmcd, etc from input->output unchanged

    22 avril 2021, par QRrabbit

    Please help me, with hopefully specific ffmpeg arguments to include in my video encoding.

    


    My work is only related to video stream, so this is the only one I'm changing.
I receive a .mov file(s) that have already been pre-compiled for a specific broadcaster, some of those selfcontained videos have 4 streams (1 video, 2 audio, and some other timecode stream). Others have up to 17 streams : 1-video, 15-audio streams and the final one is unsupported tmcd.

    


    My process pipeline includes only re-encoding/re-processing video stream, and everything else I need to pass along to the output file - all other streams without any changes or alterations.

    


    During this step of encoding, I insert icon.png into position 5:21 from sec 2-3, from 4-5, and from 6-8. To achieve this, I use map option, so my encoding string looks like this :

    


    ffmpeg -i in.mov -i icon.png -i icon.png -i icon.png
    -filter_complex "  [0][1]overlay=5:21:enable='between(t,2,3)'[v1];
                      [v1][2]overlay=5:21:enable='between(t,4,5)'[v2];
                      [v2][3]overlay=5:21:enable='between(t,6,8)'[v3]" -map '[v3]' -map 0:a
    -c:v dvvideo -pix_fmt yuv422p -b:v 115084915 -maxrate 115084915 -minrate 115084915 -r 29.97 -top 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -vtag dvh6
    -c:a copy -c:s copy -y out.mov


    


    The problem is that the out.mov only shows with 2 streams instead of 17 (1-video, and 2-audio). All other 15 streams are truncated completely.
Reading some other stackoverflow posts I found a way to transfer all other streams, is by using -map 0 :

    


    But as I tried adding -map 0 on my last line :

    


        ...
    -map 0 -c:a copy -c:s copy -y out.mov


    


    but this doubles the number of streams from 17 to 34 - also double in output file size.
If I remove map '[v3]' -map 0:a from my original encoding string and only include -map 0, I get correct number of streams, but, of course icon.png is not getting inserted at the right time. What should I do ?

    


    If there's a way to re-map my -filter_complex to overlay images without using this -map option ? Or, be specific at what each -map referring to ?

    


    If not, what other arguments/parameters can I use, if such option even exists, to copy all streams, subs and all other audio, potentially some other signal for audio impairment, if such exists.

    


    Please help, so I can finally wrap my output and submit my work.

  • Unable to get nginx-vod-module plugin to work

    31 octobre 2020, par AAP

    My first time trying hands on nginx-vod-module or any video streaming for that matter.
I just want to play static mp4 videos which I place on the server but via hls instead of direct mp4 access. No actual live streaming

    


    Q1. Am I right in understanding that a mp4 video which I place locally on my server, will automatically get broken down into segments for HLS ?

    


    My nginx installation is here : /opt/kaltura/nginx
The mp4 file is placed at /opt/kaltura/nginx/test/vid.mp4

    


    In ../nginx/conf/server.conf, I have this :

    


    location /hls/ {
            alias test/;
            vod hls;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 4000;

            include /opt/kaltura/nginx/conf/cors.conf;
        }
location / {
            root   html;
        }


    


    Now, I am able to access the m3u8 file :
curl http://104.167xxxxx/hls/vid.mp4/index.m3u8

    


    But when I try to open this file via VLC, I see these errors in errors.log :

    Q2 : Is https must for this to work ?
Q3 : I dont see any /hls/vid.mp4 folder created anywhere on the server. Do I have to manually run ffmpeg separately to create the hls segments ?

    


    What wrong am I doing ?

    Changed Paths :
     Modify /examples/set_maps.c



    set_maps : Flush encoder.

    According to the current API spec we need to call vpx_codec_encode() until
    vpx_codec_get_cx_data() returns NULL.
