Multiple input files "wildcard" feature request

Using "thingy%03d.jpg" to read a whole pile of images works well, now I'd like
to get all ambitious by specifying something along these lines:

thingy%[regexp]r.jpg

"Regexp" would be any standard regular expression, immediately carrying three
benefits: [1] specifying a sequence of images with (an) interruption(s) would
produce the generally-expected result of including all of the matched images,
regardless of numerical gaps; & [2] the images would not need to be numerically
named at all; & [3] specifying a subset of the available images would be much
simpler.

The trailing 'r' is conceptually optional, however advantages in requiring it
include the ability to do things like prefix it with 'i' to make the matching
case-independent, make it 'R' to reverse the order in which matches are
processed, prefix it with 'd' or '/' to prompt recursive file-searching, etc.

It would be convenient (not necessary) to be able surround the regexp with
{braces} or (parentheses) rather than [brackets] as this would permit more
flexibility in specifying a regexp from whatever application (or shell) spawned
the ffmpeg instance.

It would be Unixly programmatic to be able to specify (subexpressions) within
the regexp & deploy those in settings (so 'frog%[.*\(\-[0-9]*\)\.jpg' would
match frogABC-12.jpg then frogPQR-8.jpg then frogXYZZY-27.jpg, making the
parameter -12, -8 or -27 available as a frame-time in seconds... wrap your head
around this idea:

ffmpeg '-r%1/(0-\1)' 'frog%[.*\(\-[0-9]*\)\.jpg' -target ntsc-dvd -y mydvd.mpg

video dimension restrictions

Hi,
i have a video with dimensions 452x360 but when is playing i have 4 pixels 
vertical line at the right side of video.

When i convert it to 448x360 or 456x360 it is shown just right.
So it must be that width and height devided by 8;

Is there any flag that can i play my video with the original dimensions?

Also vlc can play this video with the original dimensions correct;

[issue2659] ffplay won't close after playing streaming


New submission from Perry <rypervenche <at> yahoo.fr>:

This used to work for me just fine up until maybe a week or two ago. I'm 
not sure exactly when, I haven't used it for a little while. The command 
I use is "ffplay mmsh://bcr.media.hinet.net/RA000060" and it plays a 
streaming radio and opens a visual window. When I press "q" it should 
close it after about a second. However, it now hangs and will not close 
until I either close my terminal or open a new terminal and type 
"killall -9 ffplay". I asked someone in the irc chatroom and he 
confirmed he too has this problem. I am using Ubuntu 10.10 and I 
compiled ffmpeg from git://git.ffmpeg.org/ffmpeg.git .

Here is an example output.

[issue2658] Generating a Tiff from a video throws a seg fault


New submission from Adam <adhocbot <at> gmail.com>:

I tried to run the following command but I get a seg fault.  It appears to be
the case with any type of video.  It sometimes works when -ss is before -i but
for a variety of reasons I can't use this approach.  Regardless I tried that
approach on this file and it didn't work.  

ffmpeg -strict inofficial -y -i sample.mp4 -ss 40 -r 1 -vframes 1 -f image2
sample.tiff

output: http://pastebin.com/6XnwNMDB

same bug with git-N-28415-g3efbbbb

[issue2658] Problems decoding 48-bit PNGs and tifs


New submission from Mathias <a>:

I tried to encode the 16-bit per channel Sintel pngs and all I get is a funky
output:
http://i.imgur.com/Dmvmy.png

I tried the following:
mplayer mf://720p/00001*.png
x264 --demuxer lavf %08d.png
and piping from ffmpeg (forgot the command line) to x264, all of them produced
the same problems.

On these files:
http://media.xiph.org/sintel/sintel-4k-png16/

These are my versions:
MPlayer SVN-r1.0~svn-r32667-4.4.5 (C) 2000-2010 MPlayer Team (from some Ubuntu
repository)
My local ffmpeg is FFmpeg version git-203df50, Copyright (c) 2000-2011 the
FFmpeg developers

(libswscale 0.12.0)

and x264 from x264.nl 2011-02-19 03:32:20 (32bit) with probably a recent ffmpeg

[issue2657] 688c22e causes ffplay to freeze after pressing q on streamed content


New submission from Lou <lou <at> fakeoutdoorsman.com>:

In retry_transfer_wrapper, do not check url_interrupt_cb, causes problems
commit 688c22e033a48ebf84fb4b52642bbd40f11e9c4e

Pressing 'q' to exit ffplay during playback of streamed content will cause
ffplay to freeze. Works as expected with normal files on the host machine and
progressive downloaded content via http. This is a regression. Tested with Arch
Linux x86_64 and Ubuntu Maverick.

Tested with these inputs:

[issue2656] ffmpeg-created JPEG2000 .mov fails to play in Quicktime


New submission from Misty <misty.de.meo <at> humanrightsmuseum.ca>:

JPEG2000 videos remuxed into Quicktime .mov are unplayable by Quicktime.

I begin with a valid .mj2 produced using Kakadu's kdu_v_compress (http://www.kakadusoftware.com/).
The 
video contained only a video track, no audio. I attempted to remux this into Quicktime .mov in order to be 
able to view the video with Quicktime, but the video was not readable by QT. The image displayed as a 
black screen, and the aspect ratio was displayed as 1:1. ffmpeg is able to read the video (first component 
only) and correctly transcode to another codec, albeit with incorrect aspect ratio again. (I'll file a 
separate issue for the aspect ratio.)

The commandline used was ffmpeg -i bbb_jp2.mj2 -vcodec copy bbb_jp2_ffmpeg.mov

Quicktime can properly render still frames encoded by Kakadu, so the compression itself is not the 
problem. I can produce a JPEG2000-compressed video in QT using QT's compression, which plays back in QT 
but which cannot be read properly by ffmpeg.

I've tried MJ2 files in rgba and yuv420p colour spaces, with the same results.

ffmpeg -V 9 -loglevel 99 -i output for MJ2 copy:
