ffmpeg : need for speed
21 juillet 2012, par roufamaticI am using ffmpeg to convert a set of images (bmps) with an audio track into Web ready video. Target formats are h.264 mp4, webm and flv.
This is on a Windows Azure extra-large instance (8 proc) using the prebuilt zeranoe static builds ( http://ffmpeg.zeranoe.com/builds/).Suppose I'm willing to sacrifice quality and size for raw speed. What options for each format will yield the quickest result ?
My "baseline" command looks like this (swap the extension for the other formats) :
ffmpeg -y -i frames%5d.bmp -i audio.mp3 -r 23.97 out.mp4
I can change the inputs to other formats if needed (jpg images, aac audio, etc).

How to speed up thumbnail generation for video files using FFMPEG on MIPS
6 juillet 2012, par SpottsworthI'm using the following command to get a thumbnail from a video file. It uses the seek option to grab a thumbnail. The problem is that this command takes up quite some time especially with certain containers such as MPEG-2 TS. (As much as 40 seconds). If I vary the point (duration) at which I want to grab the thumbnail , it does not seem to have an impact on the time taken. Of course when I run this on my Linux workstation, it hardly takes 2 seconds to produce the thumbnail. Any suggestions to speed up the process on my MIPS board ?
./ffmpeg -ss 18 -i input.ts -vf select='eq(pict_type\,PICT_TYPE_I)' -vframes 1 -an -s 150x100 thumb.jpg

playback speed of ffmpeg-stitched python video plots
30 juin 2012, par user1211129I've been generating videos out of plots made with matplotlib using a line of ffmpeg code. The output is in .mp4 format. However, when I tried to heighten the resolution of each individual plot to dpi=800, the resultant video (at 140 MB) lags severely when played back with quicktime. Is there a way around this ? I do wonder, if the file's too large to play efficiently, why does a movie of 6 GB play flawlessly ?
