MPEG4 in Surreal UI

[Sirber]

What should I do?

[Latexxx]

You could start with Xvid and Divx and later add support for libavcodec when your program is more mature. The first release doesn't have to support everything.

[Sirber]

the first release will be RealVideo only, this vote is for the future VFW part.

ffmpeg/libavcodec is not using vfw

i guess ffmpeg is the most advanced mpeg-4 codec around (meaning the options it offers) but i dunno if it would offer a similar quality like xvid for example

Read doom9's shootout ;).

What about FFVFW?

Bilu

[bond]

ffvfw is a vfw codec using libavcodec

[Sirber]

if it uses VFW or not, what's the big deal?

[bilu]

You need VFW for Avisynth input, unless there is a way to provide it to FFMPEG directly. But with FFVFW, the VFW interface for libavcodec, the problem gets solved :)

avisynth has nothing to do with vfw

Oo, bad statement. AVISynth makes fake AVI files through the use of the vfw interface. And you need either vfw or a COM interface (afaik) to request a script.

[bond]

huh didnt know that avisynth is so vfw related :eek:

[Sirber]

so if FFMPEG is not VFW complient, I can't use AVISynth with it? :confused:

if I use FFVFW I'll need avs2avi, as for XviD and DivX. If so, I might drop DivX 5 and WMV9, and just keep RV10/9/8, XviD and VP6.

[bond]

sirber wants to use a commandline encoder if possible i assume

but all-in-all ffmpeg offers that much options i cant believe it cant handle .avs input, its surely possible :)

[Sirber]

commandline give much more power using 1 interface. VFW UI change often, which need to update the GUI using it quite often :)

Latest build here: http://www.ligh.de/software/ffvfw/ffvfw-20031117.exe
Latest AVS2AVI : http://daveel.leffe.dnsalias.com/avs2avi-131a.zip

Registry keys here HKEY_CURRENT_USER\Software\GNU\ffvfw

Then use avs2avi MOVIE.AVS MOVIE.AVI -c ffvfw

( -c <4cc> : Use codec having <4cc> with default settings )

With the settings you changed in the registry. A lot of tools work this way with XVID, so why not with FFVFW? ;)


Bilu

[Sirber]

XviD can be all configured in registry? :eek:

[bilu]

HKEY_CURRENT_USER\Software\GNU\XviD

:D

Once upon a time I made an encoder called R4R_ENC, made entirely out of batch files and Avisynth scripts, that changed XVID settings in the registry, including file size for the 2nd pass.

Dolemite's DVX and others also use this method.

yeah I remember... great :)

registry I shall use for interface :cool: hum... does VP6 also uses registry? :D

Yes for everything but the bitrate. To set the bitrate you can use the iccompressframes message. for reference sake here's a snippet ..

ICCOMPRESSFRAMES iccf;
memset(&iccf, 0, sizeof iccf);
iccf.dwFlags = 0;
iccf.lpbiOutput = &m_biOut; // bitmap info of expected output
iccf.lpbiInput = &m_biIn; // bitmap info of input
iccf.lStartFrame = 0;
iccf.lFrameCount = 0; // ?
iccf.lQuality = 0; // not used by vp6
iccf.lDataRate = 38400; //bytes per second about 300 kilobits
iccf.lKeyRate = 300;
iccf.dwRate = 29970;
iccf.dwScale = 1000;
ICSendMessage(m_hic, ICM_COMPRESS_FRAMES_INFO, reinterpret_cast<DWORD>(&iccf), sizeof iccf); // m_hic is a compressor handle

[Sirber]

could it be possible to add bitrate into registry? would be much easier :)

[CruNcher]

Sirber sure it is but you dont have to forget to set use_2pass_bitrate and be carefull with what you are manipulating you can have alot of false results if you set some switches wrong ;) you even can set the Q Matrix via the registry and ofcourse theirfore the quanttype thats used.
for example

mode 0 = single pass
mode 1 = firstpass
mode 2 = secondpass

quant_type 0 = h263
quant_type 1 = mpeg
quant_type 2 = custom

stats = stats file
desired_size = only works if use_2pass_bitrate is 0
bitrate = only works if use_2pass_bitrate is 1

gets used if quant_type 2

qmatrix_intra"=hex:08,10,10,10,11,12,15,18,10,10,10,10,11,13,16,19,10,10,11,\
12,14,16,19,1d,10,10,12,15,18,1b,1f,24,11,11,14,18,1e,23,29,2f,12,13,16,1b,\
23,2c,36,41,15,16,19,1f,29,36,46,58,18,19,1d,24,2f,41,58,73

"qmatrix_inter"=hex:13,13,13,13,14,16,19,1d,13,13,13,13,14,17,1a,1e,13,13,14,\
15,17,1a,1d,22,13,13,15,19,1c,20,25,2a,14,14,17,1c,23,2a,30,38,16,17,1a,20,\ 2a,35,40,4d,19,19,1d,25,30,40,53,68,1d,1e,22,2a,38,4d,68,89

the rest of the functions should be self clearing like all the curve setting for 2 pass and the profile switches for the 1st pass some switches in 1pass also have no effect because core doesn't use them (fast1pass).

Use FFMPEG/libavcodec, linked statically, and write native MKV files with it :) ...

[Sirber]

I might add FFMPEG, but after XviD / VP6.

Priority:
1) Helix Producer
2) avs2avi
3) FFMPEG

You are hijacking every thread you can :D ...

Originally posted by Latexxx You are hijacking every thread you can :D ... ... he was asking opinions, here is mine. If he does what he is planing above, his app will be one like many other, at least in this respect. With writing of native MKV files from either FFMPEG or xvidcore.dll, he would be the first to do it, since very unfortunately DaveEL never got avs2matroska working properly :( .....

Nobody, of course, can expect me to tell him that then he also had the chance to add direct MP4 output, putting his app in a row with NeroDigital, for creation of spec compliant MP4 files, but with b-frames ;) ....
