Title: I will pay you 0.035BTC to solve my libav (video software) [SOLVED] Post by: CatsLikeToStretch on October 18, 2015, 10:26:01 PM See screenshot below. I specify that I want 30 fps, but it actually makes the video at 25fps. I don't know how else to pass the framerate parameters. I WILL pay you. Check my posting history - I have paid off several similar bounties in the past. Its all I use this forum for.

500k bitrate seems a bit low for the 30fps video. Can you do it at least 2000k (if your video 720p) or at least 3000k (if your video 1080p)?

Yes, I've had it much higher, over 10000k - I just happened to pick 500 when I did the test for purpose of screenshot. In all cases, it still defaults back to 25 fps.

./avconv -framerate 30 -f image2 -i %08d.jpg -b 500k video.mp4 (This one passes framerate parameter as global, not inline video option).

You get the BTC, please let me know where I should send it.
I must say this was really frustrating. What is the difference between global parameters and inline parameters?

What is the difference between global parameters and inline parameters? https://libav.org/avconv.html#Synopsis The generic syntax is: avconv [global options] [[infile options][‘-i’ infile]]... {[outfile options] outfile}... Well, probably global parameters apply to all, infile (not inline sorry for confusion) or outfile options are local or predefined. When you choose -r 30 and video.mp4, it overrules 30 fps because of *.mp4 (I presume). edit: thanks for the payment dude. |
