• 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 E

  I 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 :

  


  $ dash-demo.sh

• Can I input a PHP file to ffmpeg ?

  6 avril 2023, par cantsay

  I want to use ffmpeg, but pass in a PHP file (which will perform some logic, and then output a video file).

  


  I know you can do this on webservers, i.e. create "image.jpg" but have it contain PHP code, and when someone visits it, it will run as a PHP script.

  


  If I run the PHP file, it outputs a video file, and if I pass a video file directly, the stream works so I know those parts are fine by themselves.

  


  However, I believe the issue is that the PHP file will never be processed as a PHP file, whereas a webserver would know that ? So do I need to somehow trick it or create an alias file or similar to process the PHP file and return the video output ?

  


  I thought maybe I could pass in a bash file, which runs the PHP script using the php command but that didn't work.

  


  I'm not sure what else to try or where to look
