Does mpeg-ts support VFR?
It sure does.
VFR means Viriable Frame Rate.
No, it means variable frame rate. ;-)
Mediainfo cannot show frame rate mode for most .ts files.
This mailing list does not worry about mediainfo. What's your issue?
I have recently updated ffmpeg from version 2.0.2 to the most recent
release 2.7. I installed it using the same building configuration as the
old version and the same codecs version (libvpx and h264). When I tried to
transcode an mp4 video to webm, I found out that the speed of the new
version is

Hi all ,
I have two files one is having both audio video stream(180 secs) and other is
having only video(30 secs) . The output required is such that the for initial
part there is only the first video on whole screen then after 20 secs the
second video should come and the first video overlays

I've noticed that the cpu goes wild when I use libx264, it doesn't matter

If I don't use it, then the cpu stress stays at around 90-98%.
Now, the video quality can't be compared. the libx264 compression is great

Hi,
I want to compile ffmpeg with just webm codecs (vp8 and opus) in MinGW. I
compiled libopus and libvpx and both are recognized by pkg-config:
$ cat /usr/local/lib/pkgconfig/vpx.pc
# pkg-config file from libvpx v1.4.0
prefix=/usr/local
exec_prefix=${prefix}
libdir=${prefix}/lib
ffmpeg command line:
ffmpeg -y -i 122400.mp4 -c:a ac3 -b:a 64k -ar 44100 -c:v libx264 -b:v 300k
-s 1280:720 -pix_fmt yuv420p -g 60 -preset veryfast -threads 0

v4l2-ctl doesn't show the h.264 stream (I don't have access to the
system to paste the output).
It seems that on the C930e the h.264 is mixed in to one of the other
streams. I have posted on the ffmpeg-devel and uvc-devel lists but
without any reply.
I've moved on to try to use a Raspberry
