• Could not find tag for codec h264 in stream #2 when trim video and add watermark, music background

  13 août 2020, par Nguyễn Trọng

  I'm doing cut video into chunks, then join them and add watermark and background music with the command below.

  


  "[-y, -i, /storage/emulated/0/WhatsApp/Media/WhatsApp Video/VID-20200726-WA0154.mp4, -i, /storage/emulated/0/FXMotion/.cache/.watermark/logo_watermark.png, -stream_loop, -1, -i, /storage/emulated/0/WhatsApp/Media/WhatsApp Documents/DripReport_-_Skechers_(Lyrics)(MP3_160K).mp3, -filter_complex, [1:v]scale=640/4:-1[logo1];[0:v]trim=0:2.483,setpts=PTS-STARTPTS[v1];[0:v]trim=2.483:7.45,setpts=2.0*(PTS-STARTPTS)[v2];[0:v]trim=7.45:9.933,setpts=PTS-STARTPTS[v3];[v1][v2][v3]concat=n=3:v=1[video];[video][logo1]overlay=main_w-overlay_w-10:main_h-overlay_h-10[vw], -map, [vw], -map, 2, -c:v, libx264, -crf, 23, -preset, veryfast, -shortest, /storage/emulated/0/FXMotion/FXMotion-200810e.mp4, -hide_banner]"


  


  But when running I get the following error :

• ffmpeg : How to preserve input metadata when copying / resizing [duplicate]

  16 mars 2021, par Ivan

  I would like that the output file has the same metadata as the input

  


  I have two case :

  


  

  1. with images

  


  


  find . -name "*.jpg"|while read fname; do
  ffmpeg -y -i "$fname" -map_metadata 0 -vf scale=1024:-1 ./compressed/"$fname"
done


  


  

  2. with video

  


  


  find . -name "*.mp4"|while read fname; do
    ffmpeg -y  -i "$fname" -map_metadata 0 -vf scale=1024:-2,setsar=1:1 -c:v libx264 -c:a copy ./compressed/"$fname"
done


  


  In both cases, meta data is lost (data of edited set current date, can I move "edited date" from original file)

  


  Parameter -map_metadata 0 does not help

  


  Tell me please, what should I fix ?

  I use ffmpeg to stream video from the source to destination. The workflow is as follows,
  At the source using ffmpeg, I stream live feed from a webcam using tcp and also save a copy of the live video as mp4 file locally and the command I use is

  At the receiver, I take the tcp url as the input and output it to an mp4 file.

  $ffmpeg -hide_banner -i tcp://hostname:port?listen out.mp4 /path/to/.mp4

  The output is

  From the ffmpeg processes running on both ends, if you notice the number of B frames at the receiver is more than the B frames at the sender. In other cases that I tried, the number of I as well as P frames are higher at the receiver than that at the sender.
  Can anyone please tell me why is it so ? I am not able to figure out why.
