FFMpeg : reencode audio file to have the same codec params as another file [closed]
11 mars 2023, par EvilOrangeI need to merge three audio files :


- 

- big1
- small1
- big2








Codecs in these files may differ (but big1 and big2 which always have the same codec)


small1 is about 20-30 seconds


Now I'm using the following command for that :


ffmpeg -i big1 -i small1 -i big1 -filter_complex concat=n=3:v=0:a=1 -c:a {big1.extension} -vn out.{big1.extension


it's working, but this will require reencoding and it's slow.


I think, that it can be optimized by using concatenation without reencoding : https://trac.ffmpeg.org/wiki/Concatenate


But I need the same codec for all files.


So, now I need the following :


- 

- Get codec information from big1
- Reencode small1 to the same parameters
- merge files using concat demuxer without reencoding








So, I need a way to get codec information and pass these params to ffmpeg to convert small1.


I'm not tied to ffmpeg, if another linux cmd tool can do the same ( fastly merge three audio files) - it's also acceptable.

ffmpeg build thumbnail sequence while transcoding
9 novembre 2018, par RedtopiaWith the goal of improving performance while processing a video file and outputting it into 3 parallel output files, would it be possible to also build a thumbnail sequence as another parallel output or in another process ?
To create the 3 parallel outputs, I’m following the example on this page : https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs
...and using this example :
ffmpeg -i input \
-s 1280x720 -acodec … -vcodec … output1 \
-s 640x480 -acodec … -vcodec … output2 \
-s 320x240 -acodec … -vcodec … output3My command to generate thumbnails looks like this :
ffmpeg -f image2 -ss 2 -r "1/3" -s 100x50 ./thumbs/th-%04d.png
I’m using the ffmpeg 4.1
What I’m finding is that building a series of thumbnails, say 1 every 10 seconds, can be quite time consuming for large video files, so I’m guessing I could save some processing time if I could build the thumbs at the same time.
