Ffmpeg input seeking - "Invalid NAL unit size"
30 janvier 2024, par DimitrisI'm trying to use ffmpeg to get a 10-second clip from the middle of a video. The execution time of the command is important, that's why I've decided to use combined input & output seeking (as illustrated here).
The input video file is a CMAF with fragmented MP4, duration of 10 minutes.


I'm testing on a Mac, Ffmpeg version is 6.1.1.


This is the command that I'm using :


ffmpeg -nostdin -y -ss 290 -copyts -start_at_zero -i https://devcdn.flowplayer.com/5f07362e-c358-41d0-857a-c64302a3fcc9/cmaf/17bdb16d-71d1-414c-a291-a028bd45b9ec/playlist_360.m3u8 -ss 300.0 -t 10 -vcodec libwebp -lossless 0 -quality 60 -compression_level 2 -loop 0 -an -sn output.webp



Result : no output file is created.


From what I understand it fails to seek position "290" in the video, probably due to "Invalid NAL unit size" errors.


Here's the output :

What I've tried so far :


- 

-
Downloaded the input file to a local directory and used it as input to ffmpeg - same results.


-
Used the mp4 file from the playlist directly as an input to ffmpeg - worked but execution time is very slow


-
Emmited the input seeking part (-ss 290 -copyts -start_at_zero) from the command - worked but also very slow in terms of execution time










Any ideas on why I'm getting "Invalid NAL unit size" and how to make the command work with input seeking ?

I manage to download all the files (init file + 10 segment files) and put them in an array


File[] files = downloadSegments();


So I have :
[0] -> file-0.m4v (which is the init file)
[1] -> file-1.m4v (1st segment)
... and so on.


My question is how can I concat/append all these files into another file (final_segment.m4v) ?


I looked around a lot and am now using 'com.arthenica:ffmpeg-kit-video:4.5.1-1'
I've last tried :


FFmpegSession session = FFmpegKit.execute("-i file-0.m4v -i file-1.m4v ... -c copy final_segment.m4v");



Is there something I'm missing ?


Also I assume that I'll have to do the same for the audio segments. So I will have 2 files (final_segment.m4v and final_segment.m4a) that I will have to merge/mix together.


If you could help me with some piece of code, that would be great.
