Unfortunately, I had switched to linux lately, so I don't have Adobe Illustrator installed anymore and I don't know of any decent linux replacement for it, so I guees I'll just have to lay out the idea here, for someone who has got it installed. The idea is simple. To create a zig-zag logo to look like a film strip, like these examples: [[Image(http://i48.tinypic.com/154cdhx.jpg)]] [[Image(http://i46.tinypic.com/10fpao6.jpg)]] The idea is not very difficult to implement and here is the simple tutorial how to do it: http://vector.tutsplus.com/tutorials/illustration /from-curve-to-filmstrip-in-adobe-illustrator/ Since it's not that difficult to create it and it looks really cool, I thought I should suggest it. If noone, who is on Winblows, is interested to create it, I'll see to make it myself when I manage to install a VM and Illustrator :) -- Ticket URL: https://ffmpeg.org/trac/ffmpeg/ticket/1424 FFmpeg http://ffmpeg.org FFmpeg issue tracker ___ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac
[FFmpeg-trac] #1425(FFmpeg:new): Clips generated by ffmpeg using segment muxer are not correctly played on some videoplayers

What I am trying to do:
I am trying to record a video stream from an IP camera (Axis 210). I am
using segment to split the output in 5 second chunks and generate a
playing list.
I would like to be able to play the videos on the playlist one after the
other seamlessly.
And/or be able to reproduce each one of the segment clips as an standalone
movie.
What happens:
During the recording there appears to be no problem, and the clips are
generated without a problem.
If I open the playlist on VLC the first clip plays smoothly. Then I have 5
seconds where VLC counter is working, but no video is played, then the
second clip is played (while the time counter goes up to something like
10/5). Then 10 seconds pause, and increasing for every clip.
It also happens when playing each of the clips separatedly.
On VLC each one will have a no video time equal to the added length of
all preceding files (equal to the start time), first plays ok, 5 seconds
before the start of video for the second, 10 for the third...
MPlayer OSX Extended plays the videos correctly, but the time line below
the image is not correct. It indicates playing time starting on start (5
to 10 seconds on de second clip, ...) but if I try to move the video using
the handle it tries to play the first 5 seconds (therefore restarting the
clip).
Gnome MPlayer plays everything as I would like it (as if those were
standalone movies of 5 second length).
Totem on Ubuntu plays it ok as well.
Quicktime opens and plays the first clip smoothly.
The rest of the clips, Quicktime opens them without any problem nor error
message, but presenting a black screen. If I click play it plays a black
screen as if everything was normal, for the duration of the clip (more or
less 5 seconds in my test). Then it stops.
On the second clip a few frames may appear at the end (the length of the
clip is 5 seconds, the start time of the stream is a little before than
the end).
Ticket #910 (closed as invalid) might be related.
The command:
{{{

Can you try this patch: [http://ffmpeg.org/pipermail/ffmpeg-

Also, to avoid crashes by memory exhaustion, you can issue {{{limit

Comment:
Ok, understood. The problem is this: when the first video ends, both
overlay and amerge consider it means EOF for them and return EOF.
Unfortunately, ffmpeg does not take that EOF return into account. Instead,
it continues to decode both files and feed the data to the filters. As no
frame is requested for the second file, they accumulate in buffersrc,
until they exhaust the memory.
There are several things that are wrong here, some I already knew about
and intended to fix, others that I just realized and need to think about.
In the meantime, you can avoid the bug using the {{{-shortest}}} option.

Comment:
Sample uploaded to samples/ffmpeg-bugs/trac/ticket1329
Without -async 1, the resulting file is very heavily out-of-sync, with
-async 1, small desync is still visible imo after 30 seconds, not a
regression afaict.
Seeking does not work for the sample, works fine with MPlayer.

With DVRMS files, i'm trying to figure out if FFMPEG is able to process the files correctly or not? If every DVRMS file is dropping frames then possibly something is wrong with FFMPEG. Is my assumption correct?
