什么是保本基金的保本模式?&&&&&&
本基金在严格控制风险并保持较高流动性的前提下,力争为基金份额持有人创造稳定的、高于业绩比较基准的投资收益。
法律法规及监管机构允许投资的金融工具,包括现金,期限在一年以内(含一年)的银行存款、债券回购、中央银行票据、同业存单,剩余期限在397天以内(含397天)的债券、非金融企业债务融资工具、资产支持证券,以及中国证监会、中国人民银行认可的其他具有良好流动性的货币市场工具。
如法律法规或监管机构以后允许基金投资其他品种,基金管理人在履行适当程序后,可以将其纳入投资范围。
本基金主要为投资人提供现金管理工具,通过积极的投资组合管理,同时充分把握市场短期失衡带来的套利机会,在安全性、流动性和收益性之间寻求最佳平衡点。
1、收益率曲线分析策略
货币市场收益率曲线的形状反映当时短期利率水平之间的关系,反映市场对较短期限经济状况的判断及对未来短期经济走势的预期。本基金管理人将通过分析货币市场收益率曲线,适时调整基金的短期投资策略。当预期收益率曲线将变陡峭时,将买入期限相对较短并卖出期限相对较长的货币资产;当预期收益率曲线将变平坦时,则买入期限相对较长并卖出期限相对较短的货币资产。
2、久期配置策略
久期是债券价格相对于利率水平正常变动的敏感度。通过对宏观经济的前瞻性研究,预期未来市场利率的变化趋势,可以有效地确定投资组合的最佳平均剩余期限。如果预测未来利率将上升,则可以缩短组合平均剩余期限的办法规避利率风险;如果预测未来利率下降,则延长组合平均剩余期限,赚取利率下行带来的超额回报。
3、类属资产配置策略
根据市场变化趋势,在保持组合资产相对稳定的前提下,根据各类短期金融工具的市场规模、流动性以及参与主体资金的供求变化等因素,确定各类资产在组合中的比例;再通过评估各类资产的流动性和收益性利差,确定不同期限类别资产在各资产类别中的比例。
4、回购策略
在有效控制风险的条件下,本基金将密切跟踪不同市场和不同期限之间的利率差异,在精确投资收益测算的基础上,积极采取回购杠杆操作,为基金资产增加收益。同时,密切关注央行公开市场操作、季节因素、日历效应、IPO发行等因素导致短期资金需求激增的机会,通过逆回购融出资金以把握短期资金利率陡升的投资机会。
5、流动性管理策略
对市场资金面的变化(如季节性资金流动、日历效应等)及本基金申购/赎回变化的动态预测,通过现金库存管理、回购滚动操作、债券品种的期限结构安排及资产变现等措施,实现对基金资产的结构化管理。在保证满足基金投资人申购、赎回的资金需求的前提下,获取稳定的收益。
6、套利策略
由于市场环境差异、交易市场分割、市场参与者差异,以及资金供求失衡导致的中短期利率异常差异,债券现券市场上存在着套利机会。基金管理人将积极把握由于市场短期失衡而带来的套利机会,通过跨市场、跨品种、跨期限等套利策略,力求获得安全的超额收益。
7、资产支持证券投资策略
本基金将综合运用定性方法和定量方法,基本面分析和数量化模型相结合,对资产证券化产品的基础资产质量及未来现金流进行分析,并结合发行条款、提前偿还率、风险补偿收益等个券因素以及市场利率、流动性等影响资产支持证券价值的因素进行分析和价值评估后进行投资。本基金将严格遵守法律法规和基金合同的约定,严格控制资产支持证券的投资比例、信用等级并密切跟踪评级变化,采用分散投资方式以降低流动性风险,在保证本金安全和基金资产流动性的基础上获得稳定收益。
8、非金融企业债务融资工具投资策略
本基金投资非金融企业债务融资工具,将根据审慎原则,通过指定严格的投资决策流程和风险控制制度,规避高信用风险行业及主体,定期监测分析非金融企业债务融资工具流动性,适度提高组合收益并控制组合整体久期。本基金对于非金融企业债务融资工具的仓位、评级及期限的选择均是建立在对经济基本面、政策面、资金面以及收益水平和流动性风险的分析的基础上。此外,本基金利用内部信用评级筛选模型,系统跟踪分析非金融企业债务融资工具发行主体的偿债能力、盈利能力、现金流获取能力以及发行主体的长期资本结构等要素,选择优质个券投资标的,严格控制信用风险,保护基金份额持有人的利益。
1、本基金同一类别的每份基金份额享有同等分配权;
2、本基金收益分配方式为红利再投资,免收再投资的费用;
3、“每日分配、按日支付”。本基金根据每日基金收益情况,以各类基金份额的每万份基金已实现收益为基准,为投资人每日计算当日收益并分配,且每日进行支付。投资人当日收益分配的计算保留到小数点后2位,小数点后第3位按去尾原则处理,因去尾形成的余额进行再次分配,直到分完为止;
4、本基金根据每日收益情况,将当日收益全部分配,若当日已实现收益大于零时,为投资人记正收益;若当日已实现收益小于零时,为投资人记负收益;若当日已实现收益等于零时,当日投资人不记收益;
5、本基金每日进行收益计算并分配时,每日收益支付方式只采用红利再投资(即红利转基金份额)方式,投资人可通过赎回基金份额获得现金收益;若投资人在每日收益支付时,其当日净收益大于零时,则为投资人增加相应的基金份额;若当日净收益等于零时,则保持投资人基金份额不变;若当日净收益小于零时,相应缩减投资者相应的基金份额;
6、基金份额持有人在全部赎回其持有的本基金某类基金份额余额时,基金 管理人自动将该基金份额持有人的该类基金份额未付收益一并结算并与赎回款 一起支付给该基金份额持有人;基金份额持有人部分赎回其持有的某类基金份额 时,当该类基金份额未付收益大于零时,未付收益不进行支付;当该类基金份额未付收益小于零时,其剩余的该类基金份额需足以弥补其当前未付收益小于零时的损益,否则将自动按比例结转当前未付收益,再进行赎回款项结算;
7、当日申购的基金份额自下一个交易日起享有基金的分配权益;当日赎回的基金份额自下一个交易日起不享有基金的分配权益;
8、在不违反法律法规且不影响基金份额持有人实质利益的前提下,基金管理人可在中国证监会允许的条件下调整基金收益的分配原则和支付方式,不需召开基金份额持有人大会;
9、法律法规或监管机构另有规定的从其规定。

Subject: [FFmpeg-user] flv video truncated in conversion to mxf
Message-ID:
I am using ffmpeg (version 0.10.2) to convert an flv (Sorenson Spark video & Speex audio) into an MXF file. I get a warning "Missing Speex header, assuming defaults." and transcoding proceeds. But?the 50-second input file is truncated to 46 seconds in the MXF output.?
This video was generated using a Flex app and FMS Server 4.0.?
I have provided detailed outputs below.
Would greatly appreciate it if anyone can shed any light on why the file is getting truncated.
PS:?One thing I noticed is that MediaInfo shows the Audio Sampling rate as 5500 Hz while ffmpeg is assuming that it is 16000 Hz. I tried to force ffmpeg to use 5500 as the Audio sampling rate for the input file by providing "-ar 5500" before providing -i . But that gave me the error "Option sample_rate not found.".
Command line I am using:
====================
ffmpeg -i ~/MEDIA/test7.flv -ss 0.000000 -r 29.97 -threads 4 -vcodec mpeg2video -pix_fmt yuv422p -q:v 1 -intra -ar 48000 -async 1 -q:a 1 -f mxf test-out.mxf
(I tried adding the -t option. That did not help)?
$ffmpeg -i ~/MEDIA/test7.flv -ss 0.000000 -r 29.97 -threads 4 -vcodec mpeg2video -pix_fmt yuv422p -q:v 1 -intra -ar 48000 -async 1 -q:a 1 -f mxf test-out.mxf

No, and I believe that includes any external libraries supported by
FFmpeg. Decoding is supported natively, however.
$ ffmpeg -codecs 2>&1 | grep vp6
On2 VP6 (Flash version, with alpha channel)

If you want support on this mailing list, you will have to post
the command line you used to produce the output file that
is not correct together with the complete, uncut console output.
The reason I did not ask for complete, uncut MediaInfo output is
that I do not (easily) remember an issue where it helped.
Is the problem also reproducible with the internal ASP encoder?
(Problems that do not depend on external libraries typically are
fixed easier / faster.)

Please try current git head and / or provide the input sample.
(Why do you use -async 1? Is it needed for A/V sync?)

Subject: [FFmpeg-user] ffvp8 decoder on Beagle board
Message-ID:
i am new to ffmpeg ,
i want to measure the performance timing of ffvp8 on Beagle Board with
linux image.
ffmpeg is configured with following options,
./configure --target-os=linux --arch=arm --cpu=cortex-a8
--enable-cross-compile --cross-prefix=arm-none-linux-gnueabi-
--cc=arm-none-linux-gnueabi-gcc --extra-cflags="-Wall -pipe -mcpu=cortex-a8
-mfpu=neon -mfloat-abi=softfp"
then i run the stream with options,
./ffmpeg -c:v vp8 -benchmark -i 2_part_015.ivf
i get utime = 38.03 secs for total transcode process.
when i take utime for only vp8_decode_frame() function(in vp8.c file) it is
31.14 secs
which one i want to take to compare with libvpx ?
Is ffvp8 still faster than libvpx ?
please correct me if anything is wrong.

Inlined follows a patch / hack that allows decoding your sample,
I don't know much about the format, so I don't know how this should
be done correctly.

I think this means use FFmpeg's internal mpeg4 encoder instead of the external libxvid encoder.
To me, your command looks good:-
ffmpeg -i avisample.avi -vtag XVID -vcodec libxvid -s 160x128 -aspect 5:4 -r 15 -acodec mp2 -ar 44100 -ac 2 -ab 128k output.avi
But try this command instead:-
ffmpeg -i avisample.avi -vtag XVID -vcodec mpeg4 -s 160x128 -aspect 5:4 -r 15 -acodec mp2 -ar 44100 -ac 2 -ab 128k output.avi

I don't have a solution...
just some suggestions...
Maybe your source file "avisample.avi" is no good/not suitable.
Repeat the libxvid/mpeg4 runs with some different videos.
Maybe there is something peculiar about the *device*.
Research manufacturers' website/forum/helpline.
Also scour google to see if other people have good settings for FFmpeg or MEncoder or whatever.

(Why do you use -async 1? Is it needed for A/V sync?)

Subject: [FFmpeg-user] Problems Converting JPEG Image Files to MPEG Movie
Message-ID:
I've been working on this for about a week now.
I've read the manuals
and done some Googling, but just can not figure out what I'm doing wrong.
It is probably something obvious I'm missing.
I have over 15,000 jpg files
I want to combine into a single mpeg movie file and everything I've tried
If I try to process all the files I get a `Segmentation fault'.
If I try to process 100 files or more I get an error message and no output
If I process 99 or less files, I get my output file fine.
command is:
ffmpeg -i *.jpg out.mpeg
The above command works for < 99 image files.
The moment I add one more file,
"Error while opening encoder for output stream #0.0 - maybe
incorrect parameters such as bit_rate, rate, width or height"
I get the above error from 100 to 118 files.
With 119, I get the
`Segmentation fault'.
This is the end of the output:
Input #0, image2, from '0001.jpg':
Duration: 00:00:00.04, start: 0.000000, bitrate: N/A
Stream #0.0, 1, 1/25: Video: mjpeg, yuvj422p, 320x240, 1/25,
25 tbr, 25 tbn, 25 tbc
Segmentation fault
I'm running under Scientific Linux 5.7, a Red Hat rebuild.
ffmpeg version is 0.6.5
This is the most recent RPM build I've found.
The system has 4GB memory and 16GB swap.
I've used the `limit' command
to put all my resources to `unlimited', except for descriptors=1024 and
maxproc=36864.
The last 2 are the defaults and seem reasonable.
a time crunch so any help would be greatly apreciated.

Please try to imagine what the shell does with "*.jpg" and you
will understand that this cannot work.
If your files are pic001.jpg - pic999.jpg use:
ffmpeg -i pic%3d.jpg
If they are named (completely) differently, you will have to
use the new glob syntax, unfortunately, I don't know how it
works (yet)...

This is too old (apart from the fact that it produces the segfault

I suspect the reason is that audio ends prematurely and the
mxf muxer stops muxing if no audio is provided (but this is
just a guess).
If you decide to open a ticket on trac, please provide the
sample and complete, uncut console output (again).

Yes, I noticed that your working video was created with MEncoder.
And no, I don't really believe that MEncoder can do anything that FFmpeg can't.
But if you want to try it out...
This command might be OK:-
mencoder avisample.avi -ffourcc XVID -vf scale=160:128 -aspect 5:4 -ofps 15 -ovc lavc -lavcopts vcodec=mpeg4 -oac lavc -lavcopts acodec=mp2:abitrate=128 -o output.avi

yes, there is
mencoder can join multiple video into one file while transcoding, even
using 2pass mode
mencoder can use vfw based codec to encode video
i still believe that the avi container is the fault
so, before trying guano's suggestion, do you care to try this first?
it doesn't transcode the video just remux it, s)

what i'am doing is making a bunch of temporary simlinks with correct
naming (as noted), then feeding them to ffmpeg, then deleting them.
p.s. are there any docs about the new glob syntax?

The explanation is in the FAQ: "-profile option fails when encoding H.264

I record a logitech pro 9000 webcam with ffmpeg, using libx264 I realise
lately when the FPS drop the file then become corrupted and is unreadble
after the fps drop - image is fix and the video remain at the same time.
As I use a loop to record the webcam by lapse of 10 minutes, is there a
way to monitor the FPS and then stop and restart the command rather than
waiting the remaining time (from the 10 minutes) ?
Alternatively, why would the FPS drops? Is there something to do to
I use the following command to record the video.
ffmpeg -t 600 -f alsa -i pulse -acodec ac3 -f video4linux2 -s 960x720 -r

Subject: [FFmpeg-user] q values and bitrate
Message-ID:
I'm trying to encode MPEG2 files for broadcast. The spec is MPEG-2 @ 50Mbps with all frames as intra frames.
So I've done a few experiments and have come across a conundrum.
Setting the q flags like this:
ffmpeg -i input.%04d.dpx -vcodec mpeg2video -pix_fmt yuv422p -intra -qmin 1 -qscale 1 -output.mpg
gives a constant q=1.0 while transcoding and produces a file of approximately 25Mbps (although weirdly the file bitrate is given as: bitrate: 25551 kb/s while the actual stream is specified as 104857 kb/s. Is that the peak or just incorrect?)
Duration: 00:01:29.95, start: 1.000000, bitrate: 25551 kb/s
Stream #0.0[0x1e0]: Video: mpeg2video, yuv422p, 720x608 [PAR 608:405 DAR 16:9], 104857 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0.1[0x1c0]: Audio: mp2, 48000 Hz, 2 channels, s16, 384 kb/s
However, specifying a constant bit rate like this:
ffmpeg -i input.%04d.dpx -vcodec mpeg2video -pix_fmt yuv422p -intra -b 50000k -minrate 50000k -maxrate 50000k -bufsize 2000000 -output.mpg
gives a varying q whilst transcoding somewhere between 1 and 6. The resulting file is 50Mbps (in both the file and the video stream)
However, visually, the quality of this file is not as good as the 25Mbps (as suggested by the q factor), although it should be better I would have thought.
Unfortunately the files will be rejected by the broadcaster if they are not 50Mbps. So my question is how can I produce a file of 50Mbps AND q=1. It is my understanding that the q flags and the bitrate flags are mutually exclusive (I've tried running both).
Thanks very much for your help

Hello there,
I would guess your broadcaster wants not just any 50Mbps MPEG-2 file, I
think he might want an D10 (or IMX) file. You might want to take a look
at the FFMPEG Broadcast branch FFMBC. Otherwise there is a (little
outdated but still useful) HowTo site for FFMPEG:

Subject: [FFmpeg-user] ffmpeg lightweight aac wrapper
Message-ID:
hey there!
I would like to write a simple wrapper interface for ffmpeg to use it only
for aac encoding.
I already compiled slim version of the ffmpeg, and worked my way through the
avcodec and avformat header files but I'm a bit lost.
The settings for the encoding will always stay the same, and the raw audio
input will also have the same meta data (sample rate, channels, bitrate
aso.). So what I want at the end is some sort of:
void openFile( char * filename ); //create/open file with header information
and initialize encoder/decoder
uint_8 *encode( uint_8 *data, int msec ); //encode real time into the
generated file and insert encoded stream at position msec (default = 0), and
return the encoded data
uint_8 *decode( int msecstart, int msecduration ); //decode the duration
from file at postion startpos
I would really appreciate some help on how to get there with the codec,
because I don't really know where to start right now.
Thanks in advance,

Thanks for the reply!
I didn't manage to compile it in cygwin at the end. Even though I used
absolute paths like /cygwin/c/ the build process gets messed up with windows
paths (this seems to be a common problem with cygwin make)...
With some trying I managed to compile it under ubuntu, with the attached
android_build.sh at the end.
Maybe this helps some people out there.

I refer you to http://ffmpeg.org/ffmpeg.html#Stream-selection
http://ffmpeg.org/ffmpeg.html#Advanced-options
I think you will find you need -map 0:a

I run FreeBSD 9.0. I install all dependencies (libraries) from ports
generally. The easiest way to do this is to go to the ffmpeg port,
configure it with the options you want, and install all dependent
libraries. (cd /usr/ports/multimedia/ffmpeg-devel && make config &&
make all-depends-list).
A couple of additional dependencies that may not come up in that list
- lang/gcc46, and the latest devel/binutils.
Once you have the dependencies installed, this is my build script for
building ffmpeg from git:
gmake distclean
./configure --as=/usr/local/bin/as --cc=/usr/local/bin/gcc46 \
--extra-libs=-L/usr/local/lib --extra-cflags="-I/usr/local/include" \
--prefix=/usr/local --mandir=/usr/local/man --disable-protocol=udp \
--enable-postproc --enable-nonfree --enable-gpl --enable-version3 \
--enable-libtheora --enable-libvorbis --enable-ffmpeg
--enable-ffplay --enable-ffprobe \
&& gmake -j 2
Hope that helps

Thanks for your answer.
We also have to deliver IMX to some broadcasters, so I don't think this is the same spec.
I looked at this and picked out the MPEG-2 I-frame only Highest Quality Encoding settings on the same page.
I'll have a look at the IMX settings (they look fairly similar, but I'll investigate the additional flags)

Hello there,
I would guess your broadcaster wants not just any 50Mbps MPEG-2 file, I
think he might want an D10 (or IMX) file. You might want to take a look
at the FFMPEG Broadcast branch FFMBC. Otherwise there }
