How to preserve data stream with none codec from a video while compressing it using ffmpeg ?
5 octobre 2022, par rj_7I'm using the following command to compress a video of size 1.5GB to 80 MB.


ffmpeg -i input.mp4 -copy_unknown -map_metadata 0 -c copy -c:v h264 -b:v 5000k -c:a aac -b:a 48k -map 0:v -map 0:a -map 0:d output.mp4



The problem I'm facing is - it doesn't copy the data stream to the output video even when I explicitly mention it via mapping. If I don't use the -map options for each kind of stream, it just process the video and audio as expected. But I also want the data stream in my output video.


The logs for the above command are -

I've also tried mapping the streams via number, that doesn't work either (shows same logs as above).


ffmpeg -i input.mp4 -copy_unknown -map_metadata 0 -c copy -c:v h264 -b:v 5000k -c:a aac -b:a 48k -map 0:0 -map 0:1 -map 0:2 output.mp4



So, essentially my question is - How to preserve data stream (packed) with none codec from a video while compressing it using ffmpeg ?

ffmpeg concatenate image and audio to beginning of file
18 mai 2017, par swg1cor14So I want to try and use the ffmpeg MAP command to do the following :
Merge audio and jpg
Concatenate mp4 to endStill.jpg
audio.mp3 -> video.mp4 = output.mp4Right now I have
/home/admin/ffmpeg/ffmpeg -i still.jpg -i audio.mp3 render1.mp4
But I want to also go ahead and add on the video.mp4 as well. I tried reading the map function but I’m so confused as to how you know how many streams a file has, etc
Heres the output of the command....note I have different file names
