Could not write header for output file #0 (incorrect codec parameters ?) : No such file or directory Error initializing output stream 0:5 —
13 septembre 2022, par M EI am trying to create a DASH manifest and segments from an .mp4 file. I have created a bash files with the commands below, and calling bbb.mp4, but the output gives the error on the subject line. This is the script I am using :


ffmpeg -re -i bbb.mp4 -map 0 -map 0 -c:a aac -c:v libx264 \
-b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline \
-profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 \
-b_strategy 0 -ar:a:1 22050 -use_timeline 1 -use_template 1 \
-window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \
-f dash /path/to/out.mpd



After running the command for my bash file dash-demo I get :

Creating animated AVIF with FFmpeg
17 septembre 2022, par Ollie WilliamsEdit : This did eventually complete, and the output file is fine. I am using a top-end MacBook M1 Pro computer. Is it normal for it to be this relentlessly slow ? It was


My input file is an
.mov
. I used this command :

ffmpeg -i Jellyfish.mov Jellyfish.avif


I also tried converting an MP4/h264 file.
In both cases it took over 50 minutes.


It's a 5 second long clip but it has taken about 20 minutes and the output file is still zero bytes.


This is the output in my terminal :

How to fix muxer does not support non seekable output error on ffmpeg ?
19 septembre 2022, par YusufI am getting this error when I try to stream my video to YouTube rtmps server and I don't know what it means or how to fix it. Can anyone help ?


I first record my screen with Electron's MediaRecorder


then I insert metadata of to the blob (othervise Electron exports without specifying the end of the file)


I convert the webm to mp4 by executing

ffmpeg -i ${tempVideoPath} -c copy ${tempMp4VideoPath}


Then I execute

ffmpeg -re -i ${tempVideoPath} -c copy -f mp4 ${youtubertmpslink}


Finally I get this error :
