Hello everyone, I would like to limit the number of frames that are output by the avformat consumer no matter how many frames are produced.
At the moment, I can only use the command line (q)melt. This problem would be easier using the libraries directly, but that isn't an option at this time. I've dumb down the issue as much as possible, and I came up with essentially what I want is this: qmelt.exe 1.mov -consumer avformat:demo.mp4 out=200 1.mov has 540 frames. The end result is 540 frames. I do not want to put out= as a property on the producer, this is a dumb down example, a more realistic one I have is: qmelt.exe 1.mov -blank 120 1.mov -consumer avformat:demo.mp4 out=200 In this example, assume there is at least 200 frames. It doesn't matter if 1.mov has 40 or 500 frames, I still want demo.mp4 to have 200 frames. Obviously, out isn't a consume property. I've looked at the avformat docs and was unable to see any like property. I know I could just encode demo.mp4 a second time using out on the producer but that seems resource intensive for such a simple use case. Basically, I need to be able to stitch together video and blank frames and then limit the output no matter how long the clip/track. Any ideas to accomplish what I need? I would be willing to use a filter such as: qmelt.exe 1.mov -blank 120 1.mov -attach-track out_limit:200 -consumer avformat:demo.mp4 There didn't seem to be a filter, that I'm aware of, which will do this?
