Google's standard for FLV (as used on older versions of YouTube player and
Google Video player) involves at least 2 additional metadata tags. These
are starttime and totalduration. The value for starttime should be 0, and
totalduration should be equal to the official Adobe Flash Video standard

I was reading it directly from the official FFMPEG website.

All the info about the TINTERLACE filter I got from reading the info there.

According to the documentation on the TINTERLACE video filter, the filter
mode called MERGEX2 will "Move odd frames into the upper field, even into
the lower field, generating a double height frame at same frame rate." But
it doesn't do this, at least in some cases (not sure about all cases). The

I have an MP4 video, and I'm trying to extract 100 frames starting from
frame number 271. As of right now I can select duration by time using -t or
by frame count by using -frames. And I can also select starting point by
time by using -ss. However, I believe that as of now there is no command

What is top posting? I'll try to avoid it if I know what it is.

Doesn't SDL support YUV444 as a YUV format? Or does it only support YUV420?
Also, thanks for the tip about -vf format=bgra

When I decode rawvideo yuv444p in ffplay that was encoded in ffmpeg (using
the test source called "testsrc"), I notice there is blurring between
adjacent colors (both horizontally and vertically), which would typically
be present in yuv420p. I can avoid this by switching the decoder to use a

I would like to be able to deinterlace a video by converting full-height
frames into half-height fields (where each frame of the output represents
one field of the input) at double the frame rate. The way this would work
is it would take the top field (or bottom field) first and export it as the

FFMPEG should be able to output raw AAC audio stream, without any
encapsulation, in the same way that a raw h264 video stream can be output
from FFMPEG. Currently AAC audio can only be output within various
container/encapsulation formats (such as MP4 or ADTS containers). If you
try to output raw A
