H264 support in the new flash player

[wingchun22]

running centos 5

there is a couple of issues with mplayer on centos and fedora, found the fixes for thoose, but mainly my problems now are with gpac

i have tried using the bash script on massanti.com to create the mv4 files then the audio stream , but i'm having problems with mp4box

it keeps comming back libary*** .so not found, i think i might have complied it incorrectly , its a nightmare to get right

i think i just installed gpac without the extra libs, then tryed installing agian with extra libs but still big problems, when i do , which MP4Box, it comes back the path correctly, but when i try to run any MP4BOX commands in shell it always fails , been on it hours and hours searching and trying to fix it, but still having no luck getting it working

maybe i need to hire someone to sort out these issues as you can spend way to much time working on things like this, when a unix pro can come along and sort things out in just a few hours, maybe better to pay a 100$ or so, instaead of wasting away days and still not sorting out the issues




one option tho seems to be to miss of the mp4box parts of the proceess and just encode the files in mencoder with 2 or 3 passes, and just create them in mp4 format with sound

the only problem that arises then tho is you still need to insert metadata into the mp4 using mp4box or the videos are not streamable, you have to wait for the videos to download fully to watch





i have also just been doing tests on my windows computer with mp4 conversions and can create the files windows side

just running a few hd tests on files, and the only problem is mp4 files tend to come out roughly the same size as the orginal, really need to get mp4box box working on my server, so i can convert mv4, mp4 files into flv files all server side and get that smaller file size to

i also just found a really nice app for windows - you probably alreday might have seen it http://mediacoder.sourceforge.net/index.htm

this creates h264 mp4 files and has alot of config options, nice app to play around with, uploaded a couple of mp4 files on my server and i'm really impressed with the quialty and full screen resolution, users are really going to like to have the same quiatly as on the windows players when watching vids online, just need to sort these issues i guess

edit

fixed the problems

i had mp4box in /usr/local/bin instead of /usr/bin

and i just done a make uninstall on gpac and then re installed it again defining various sources as local, and it installed ok and everything now works


done a few test on batch script and it creating files crocertly and running threw the steps, now all i need to do is create a hd section on my site to allow only igh quailty vids to be encoded and just let users add crap vids to the normal sections

Whatever, as you suggested in previous posts I'm going to build own x264 commands, based on ffmpeg and not mencoder.

From what I noticed for some type of video formats, mencoder command is causing kernel bug.
It's easy to find when checking logs. Basically MPEG goes fine, but not xvid and mp4. Though final FLV files looks OK, in logs you can see conversion was not performed to the end.
What is worse - such not finished proccess causes kernel error which kills PHP interpreter in same convert script.
It has no effect on other commands in current convert file. but if you wish to add some custom code - it won't be executed. Even simple 'echo "bla,bla";'

It depends all on some server's settings and mencoder version.
Whatever, I didn't notice any failed processes using ffmpeg (which is even little bit faster).

yeah dargre it whould be very usefull to have the x264 mod for both ffmpeg and mencoder

some poeple like mencoder some poeple like ffmpeg

i perfer using ffmpeg personaly, its much easier to deal with and basicly the same things can be done i guess, also there seems to be a problem using mencoder on wmv files, sometimes they conert ok, sometimes not and on some wmv files converted to m4v then to flv you can not seek threw the file correctly

it whould be nice to try the same process with ffmpeg version to see if we run into the same problem

one good idea might be to use the nice command on processes as well, so it runs in background on a low setting not taking up to many cpu resources, and also maybe good if we have one, two or three process runing at the same time

also a que system built into this might be usefull

i have uploaded a few files , manulay run the shell scripts, then copy them over to your ftp upload mod to add them into the system

a great mod whould be to intergrate your ftp uload mod , with some sort of conversion shell script , so you upload avi, mpeg, wmv files to one folder, there all processed in m4v, mp4 then to flv, then moved into your ftp upload temp folder for a user to come along and add, that might be a usefull mod for poeple to use

one of the only probs I run into constantly with ffmpeg is its lack of converting some videos, mencoder seems to do a better job esp with the win32 libs you install.. both would be nice, and well if ffmpeg cant write out a file or fails, could default to use mencoder in case

That surprised me....
As far I didn't find single video that couldn't be converted with ffmpeg or causing problems with resync, etc.
But found many different problems with mencoder...

If I remember correctly, Mencoder does not yet support the latest version of the wmv codec. This would explain why some convert properly and others don't.

I agree though, a ffmpeg version would be nice. ffmpeg seems to much faster as well.
