FFMPEG - Store FFPROBE's duration output as a variable
12 août 2023, par user7032056I wanted to use a video's duration in the "enable='between(t,0,0)" field to make sure that I overlay an image at 1/3 of the video's duration every time.



According to FFMPEG's info on their site, I need to use this



ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 input.mp4




it does return a value but I can't seem to be able to set it to a usable variable, I already tried by using



set duration=ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 input.mp4




And then referencing it via %duration%, but no luck.



Is there a way to do this, am I doing something wrong ?



Thank you for your help.

Is there a way to store packet header information from an incoming h.264 stream ?
13 septembre 2021, par SOSparachuter1The issue : I need to convert an h.264 stream streamed over RTP into MJPEG, but for very convoluted reasons I am required to use the libjpeg-turbo library, not the mjpeg encoder that comes with ffmpeg. So the only thing FFMPEG needs to do is convert the h.264 RTP stream to rawvideo in RGBA and output to a socket where I then manually do the transcoding.


However, libjpeg-turbo only expects complete frames, meaning I need to collect rawvideo packet fragments and somehow synchronize them. Putting incoming raw video fragments into a buffer as they come results in heavily broken images.


Is there some way of saving the header information of the initial h.264 RTP packets ? The command I'm currently using is very straightforward :


-i rtsp :// : -vcodec rawvideo -f rawvideo udp :// :
