Recording application output to video using FFmpeg (or similar)
15 décembre 2011, par JohnWe have a requirement to lets users record a video of our 3D application. I can already grab the individual rendered frames so this question is specifically about how to write frames into a video file.
I don't think writing each frame as a separate file and post-processing is a workable option.
I can look at options to record to a simple video file for later optimising/encoding, or writing directly to a sensibly encoded format.
FFmpeg was suggested in another post but it looks a bit daunting to me. Is it the best option, if not what can be suggested ? We can work with LGPL but not full GPL.
We're working on Windows (Win32 not MFC) in C++. Sample/pseudo code with your recommended library is very much appreciated... basically after how to do 3 functions :
startRecording()
does whatever initialization is neededrecordFrame()
takes pointer to frame data and encodes it, ideally with timing dataendRecording()
finalizes the video file, shuts down video system, etc

Getting log line for each extracted frame from FFMPEG
3 février 2016, par wpfwannabeI am using FFMPEG.exe to extract frames from various videos. As this is a programmatic solution and getting the total frame count and/or duration can prove tricky (with ffprobe), I am thinking I could use the console output to detect individual frames’ timestamps but I am getting a single output line every N frames like this :
frame= 20 fps=0.0 q=0.0 size= 0kB time=00:00:01.72 bitrate= 0.0kbits/s
frame= 40 fps= 38 q=0.0 size= 0kB time=00:00:04.02 bitrate= 0.0kbits/s
frame= 60 fps= 39 q=0.0 size= 0kB time=00:00:06.14 bitrate= 0.0kbits/s
frame= 70 fps= 38 q=0.0 Lsize= 0kB time=00:00:07.86 bitrate= 0.0kbits/sIs there a command line option to force output for each and every frame ? If so, I could extract the
time=
portion. This is the command line currently used :ffmpeg.exe -i video.avi -y -threads 0 -vsync 2 %10d.jpeg
Ideally, replacing
%10d.jpeg
with some other format that writes frame’s timestamp but I don’t think this exists.
