FFmpeg: read an input link from a text file directly (without extra tools and pipes)












0















There is the text file - link.txt. That file contains the following link to the video:



$ cat link.txt

https://www.quirksmode.org/html5/videos/big_buck_bunny.mp4


I can transcode the video from that file in the next way:



ffmpeg -i $(cat link.txt) -vcodec libx264 -acodec libfdk_aac out.mpg


or I can use pipe to achive the same result:



cat link.txt | ffmpeg -i - -vcodec libx264 -acodec libfdk_aac out.mpg


But I have to run FFmpeg via specific software and it doesn't support pipes and commands above.

I'm looking a solution to run FFmpeg like this:



ffmpeg -some-extra-parameters -to-say-ffmpeg -get-the-link 

       -from-the-text-file -i link.txt -vcodec libx264 

       -acodec libfdk_aac out.mpg


Question 1: Is that feature implemented in FFmpeg?



Also, I checked FFmpeg presets
and created the FFPRESET file for my goal:



$ cat /usr/local/share/ffmpeg/linkpreset.ffpreset

i=https://www.quirksmode.org/html5/videos/big_buck_bunny.mp4

vcodec=libx264

acodec=libfdk_aac


I got the error when I tried to execute FFmpeg with that preset:



$ ffmpeg -fpre /usr/local/share/ffmpeg/linkpreset.ffpreset out.mpg



/usr/local/share/ffmpeg/linkpreset.ffpreset: Invalid option or argument: 

'i=https://www.quirksmode.org/html5/videos/big_buck_bunny.mp4', 

parsed as 'i' = 'https://www.quirksmode.org/html5/videos/big_buck_bunny.mp4'


Question 2: Is there way to specify input link in a FFPRESET file?
Question 3(main): How to read an input link from a text file in FFmpeg directly(without extra tools and pipes)?






command-line ffmpeg

There's no direct method to do this, but a workaround is to use the concat demuxer with a single entry.



Create a text file containing



file 'https://www.quirksmode.org/html5/videos/big_buck_bunny.mp4'


and then run



ffmpeg -f concat -safe 0 -protocol_whitelist file,https,tcp,tls,crypto -i link.txt ...
