Php and Mysql current video time duration using FFMPEG
10 novembre 2014, par innovationI have one question about video time calculator.
I am using this FFMPEG
shell_exec("ffmpeg -i ../videos/$video_name.flv -f flv -s 320x240 ../videos/$video_name.mp4");
shell_exec("ffmpeg -i ../video_images/$video_name.mp4 -vcodec png -ss 00:00:05 -s 360x288 -vframes 1 -an -f rawvideo ../video_images/$video_name.png");I want to add here to post total duration of the video.
For example : I upload a video this video time 4:10 (4 minutes 10 seconds). I want to post it this time from table row.
How can i do this anyone can tell me ? -
Adding current time as timestamp in H.264 raw stream with few frames
2 avril 2020, par MichaëlI have a program that spits out an H.264 raw stream (namely,
screenrecord
on Android). I'm using FFmpeg to add a PTS (presentation time stamp) on the frames as follows :


$ my-program | ffmpeg -i - -filter:v setpts='(RTCTIME - RTCSTART) / (TB * 1000000)' out.mp4




This filter computes the current time, and puts it as the PTS.



The trouble is that
my-program
does not produce any output if there isn't any change in the video. Since FFmpeg seems to wait for a bunch of frames before putting them through thesetpts
filter, the computed PTS won't be correct. In particular, the last frame of a sequence will be timestamped when the next sequence starts.


Is there a way (with FFmpeg or otherwise) to add the current time as PTS to H.264 raw frames, where "current time" is when receiving the frame, rather than outputting it ?



Note : The problem is not from buffering from the pipe.

running multiple tasks (ffmpeg) at the same time in a django app
23 novembre 2020, par Soufianeat the title says it, I made a django app that cuts and merge files with ffmpeg
while testing (me being the only user), it looks fine, but later when using the app from different browsers running tasks at the same time, looks like it's a queue of tasks and other users will wait for their turn,
what I'm thinking about is, is there a possibility to run multiple tasks simultaneously at the same time, like (screens on linux) under django framework ?
thanks a lot
