+Unpack DivX-style packed B-frames.
+
+DivX-style packed B-frames are not valid MPEG-4 and were only a
+workaround for the broken Video for Windows subsystem.
+They use more space, can cause minor AV sync issues, require more
+CPU power to decode (unless the player has some decoded picture queue
+to compensate the 2,0,2,0 frame per packet style) and cause
+trouble if copied into a standard container like mp4 or mpeg-ps/ts,
+because MPEG-4 decoders may not be able to decode them, since they are
+not valid MPEG-4.
+
+For example to fix an AVI file containing an MPEG-4 stream with
+DivX-style packed B-frames using @command{ffmpeg}, you can use the command:
+
+@example
+ffmpeg -i INPUT.avi -codec copy -bsf:v mpeg4_unpack_bframes OUTPUT.avi

+The best way is to install @command{pkg-config} in your cross-compilation

+As an intermediate solution, you can place in your cross-compilation

+A lot of video codecs and formats can store the @emph{aspect ratio} of the

+Most still image processing work with square pixels, i.e. 1:1 SAR, but a lot

+non-square pixels.
+
+Most processing filters in FFmpeg handle the aspect ratio to avoid

+
+For example, to fix a badly encoded EGA capture, use the following commands,
