How to split an incoming stream into multiple streams with different resolutions ?
30 janvier, par CobaltHow to split an incoming stream into several streams with different resolutions on the MediaMTX server ? There is one incoming stream in rtsp, it needs to be split into several channels with different resolutions. I think in the direction of ffmpeg, but I don't understand how to register this in the mediamtx settings.

split videos with ffmpeg
23 novembre 2020, par 5DiraptorI'm trying to create a script that scans a directory, and for all videos larger then X size, splits them down into smaller chunks.


There are two similar questions :


- 

- Using ffmpeg to split video files by size
- Split into equal parts and convert many mp4 videos using ffmpeg






Neither of these work in the way I want. The first you have to manually input every file that you want to process. The second doesn't check for filesize, or output the files in the way I want.


So far, this is the contents of the .bat file :


%~d1

for %%a in (*.MOV) do (

if %%~za GTR 2000000000 (

REM usage %%a <filename>
set "_filename=%~n1"
set "_tally=.SPLIT-%03d"
set "_extension=%~x1"

set "_outputname=%_filename%%_tally%%_extension%"


 ffmpeg -i "%%a" ^
 -crf 0 -c copy -map 0 -segment_time 00:00:30 -f segment -reset_timestamps 1 ^
 %_outputname%
)
)
pause
</filename>

My aim is for the script to work in the following way :


- 

- Drag a video (from a folder of videos) onto the .bat file.
- Script opens up, and targets each file ending
.MOV, and is greater then 2GB - ffmpeg splits the video down into >2GB chunks. (I know it's currently split down in 30 second chunks, still working on understanding how to use the
-fsparameter). - Each chunk gets saved with the original filename and extension, but the filename is suffixed with ".SPLIT" and then a unique number that relates to which file it is - first file is 000 and second is 001 etc.










Problems :


- 

- Firstly, I want to split by filesize and not time, but I don't understand how to use the -fs parameter in this case. I guess I could use something like
ffprobe -i input.file -show_format -v quiet | sed -n 's/duration=//p'in conjunction with it but I'm not confident... - Secondly, I'm getting a problem with
%03din the .bat. Think I'm mixing up languages ? It retrieves the filepath of the .bat file instead of counting number of loops.






Any help really appreciated !

How to split accurately a LONG GOP video (h264/XDCAM...) with FFMPEG ?
29 août 2013, par ManuhozMy goal is to split a XDCAM or a H264 video, frame-accurately, with ffmpeg.
I guess that the problem comes from its long GOP structure, but I'm looking for a way to split the video without re-encoding it.
I apply an offset to encode only a specific section of the video (let say from the 10th second to the end of the media)
Any ideas ?
