  • Why is ffmpeg output video contrast / brightness too bright?

    24 February 2024, by danday74

    I have a .mov file which I run through ffmpeg to create HLS segments / chunks. However, when I playback the HLS video it is too bright.

    


    For a sanity check, I ran the same .mov video file through the FlowPlayer processing pipeline and the results were the same, the output video is too bright!

    


    I have a number of videos. Most do not have this problem but some (and only some) of the .mov files exhibit this issue.

    


    A broken video stream reports (see below for full output):

    


    Stream #0:0[0x1](und): Video: hevc (Main 10) (hvc1 / 0x31637668), yuv420p10le(tv, bt2020nc/bt2020/arib-std-b67), 1920x1080, 8507 kb/s, 29.98 fps, 29.97 tbr, 600 tbn (default)


    


    A working video stream reports (see below for full output):

    


    Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 3840x2160, 45457 kb/s, 29.99 fps, 29.97 tbr, 600 tbn (default)


    


    Is this something to do with hevc v h264 (whatever they mean)?

    


    Incidentally, I am using the native HTML5 video player in conjunction with hls.js to playback the videos.

    


    How do I fix this?

    


    Here is my ffmpeg command:

    


    ffmpeg -i "rgb.mov" \
  -v warning -preset ultrafast -g 59.96 -sc_threshold 0 \
  -map 0:0 -map 0:0 \
  -s:v:0 1920x1080 -c:v:0 libx264 -b:v:0 4521k \
  -s:v:1 1920x1080 -c:v:1 libx264 -b:v:1 7347k \
  -var_stream_map "v:0 v:1" \
  -master_pl_name master.m3u8 -f hls \
  -hls_time 6 -hls_list_size 0 -hls_playlist_type vod \
  -hls_segment_filename "hls/v%v/chunk%d.ts" "hls/v%v/index.m3u8"


    


    And here are some screenshots showing the original video in comparison to the output video.

  • react native app doesn't load my video which is made by ffmpeg

    10 March 2023, by yabbee

    I'm working on react native expo project and using expo-av to play video.I'm experimenting on my iphone and it's working almost fine. I copy and paste the sample code on expo av doc and Big Buck Bunny video is loaded successfully and able to play. But, there is a video that can't be played on my app. I have a video which is stored on s3 server. This is the mp4 video made by ffmpeg command on my computer and manually uploaded it on s3. I can download it and play on my machine. But when I try to load that video on my expo app, the video doesn't show up on the component at all. I write video source correctly including https:// but doesn't show up anything. How can i solve this problem? I'm using expo 48.0.0 , expo-av 13.2.1 and expo-dev-client 2.1.5 now.

    


    Here is the ffmpeg code that I've used to make video. As you can see, I'm making a retro video by overlaying grain effect mp4 video which I downloaded.

    


    ffmpeg -i /Users/yosuke/Desktop/ffmpeg_playground/effects/grainAndFlash.mp4 -i 
{inputFilePath} -filter_complex "[0:a][1:a]amerge[mixedAudio];
[0]format=rgba,colorchannelmixer=aa=0.25[fg];[1][fg]overlay[out];
[out]trim=0:32,setpts=PTS-STARTPTS[video]" -map "[video]" -map "[mixedAudio]" -
pix_fmt yuv420p -c:v libx264 -crf 18 -shortest {outputFilePath}


    


    Here is the Expo app code

    


    import React, { useState, useEffect, useContext, useRef } from &#x27;react&#x27;;&#xA;import { View, Text, ScrollView, TouchableOpacity, Dimensions } from &#x27;react-native&#x27;;&#xA;&#xA;const Container = () => {&#xA;    const vidRef = useRef(null);&#xA;return (&#xA;    <scrollview style="{{" 1="1">&#xA;      &#xA;    </scrollview>&#xA;  );&#xA;};&#xA;&#xA;export default Container;&#xA;
