Hi Carl -- any luck digging into that video?
Thanks!

I've confirmed this does seem to be a regression.
I ran the same code with the same video on ffmpeg 0.8.3

Hi Michael -- after reading into things a bit more, I agree that it's
risky what I'm doing. However, I only need about 3 frames per second so
maybe waiting for a key frame isn't the end of the world...
Is there a safer way? The decoding is extremely expensive so I only

Hey guys,
I'm doing some simply video analysis in which I walk through frames of a
video and do some calculations on the pixel data. I started noticing some
issues with frame timing so I tried to compare my results with a simple
thumbnail extraction script using ffmpeg.exe.

Interesting. There was a difference of 30 between the frames that
ffmpeg.exe output and the result of -nb_frames.
Sure enough, ffmpeg.exe with -vsync 0 output 480 frames instead of 510
Weird -- any idea why there's only 1 key frame? I guess that's what the
camera decided to do...

Hi guys,
I have a set of .MTS files that I'm trying to splice. If I start at
0:00:00, the output video works fine. But if I start splicing any time
after 0:00:00, the output video is empty. I've used the exact same command
line with other .MTS files and had no problem. It seems like something

Hello,
I've come across a particular MTS file that doesn't seem to want to be
decoded. I've decoded plenty of other MTS, M4V, and MOV files with my code
so something seems to be unique to this one. I can play the file just fine
too. Any idea what's going on here?
Here's the media info for the

Is it designed to support batch commands?
Thanks!

Hello,
I currently use ffmpeg.exe to trim videos from point A to point B.
Something like this: ffmpeg -i original.avi -ss 0:10:00 -t 0:00:30
output.avi
Oftentimes I need to trim several clips out of the same video.
Unfortunately this means ffmpeg.exe must scan over the same sections
of video
we're getting closer!

I'm running 64-bit Lion but I need to compile a 32-bit version of
ffmpeg because another library I'm using is only available as 32-bit.
I've tried a number of different configurations but they're all giving
me errors. Here's what I've tried:
./configure --disable-static --enable-shared
-o
libavcodec/h264_cabac.o libavcodec/h264_cabac.c

Hello,
Is it possible to call an ffmpeg API to get the list of video types
that it supports for decoding and encoding? I'd want the associated
file extensions as well.
Thanks!
