Wow, we get the latest port less than a month after release. That's some great work Mick. Look forward to trying this out during the week.

Thanks Mick. Yep, I later figured out why x=10 kept appearing on the output. :-)

You're missing a colon before x=10, but also somehow the drawtext filter got disabled, or didn't get enabled, when compiling. So keep using 4.2.1 for now until I can update this.

Hmmm... the Drawtext filter isn't working with this new build, it was working in 4.2.1. 
 
This line works  in 4.2.1: 
ffmpeg -i Temp:Test.mp4 -ss 00:01:30 -vframes 1 -vf "drawtext=text='%{pts*:hms}'x=10:y=10:fontsize=24:fontcolor=white" ram:test.png 
[backslash between * and ] 
 
but with this build I get: 
 
"[AVFilterGraph @ 0x448bfcc0] No option name near 'hms}x=10:y=10:fontsize=24:fontcolor=white' 
[AVFilterGraph @ 0x448bfcc0] Error parsing a filter description around:

The previous comment doesn't show it, back there is supposed to be a backslash before each colon. The asterisks are also required. So for each colon, add an asterisk and backslash before it. The asterisk is the escape character for Amiga Shell. I also tried running it within bourne shell but didn't have any luck.

By: MickJT (115.69.35.90)

Finally figured it out. Some characters had to be escaped in a certain way. This works.

Thanks Mick. Yes, got that working. I'm trying with timecode, but I get the error that I reported. 
 
From what I've read online, this should work: 
ffmpeg -i Misc:Downloads/Red.Dwarf.S11E01.mp4 -vf "drawtext=timecode='00:00:00:00':fontfile=/Fonts/_TrueType/Comic.TTF:fontsize=30" ram:test.avi

I did a test with 
 
ffmpeg -i sample_640x360.avi -vf "drawtext=fontfile=/Fonts/_TrueType/Comic.TTF:fontsize=30:text=test 123" test.avi 
 
That worked

Hi Mick, 
 
Does -vf drawtext work with this version of ffmpeg? I have been playing around with it but I get an error "Error reinitializing filters! Failed to inject frame into filter network: Error number -22 occurred"

By: MickJT (115.69.35.90)

Damn. The Altivec version has to be compiled with a linker script (files in ldscripts/) from an older binutils, or with the -N switch when linking, in order to stop that issue from happening. I don't have an altivec capable machine myself to test, but usually get someone to check it for me before releasing. I can't remember if I did that this time. Thanks for letting me know. I can't give a timeframe for an update yet.

Hi, with this new version, I’ve got problem converting h264 videos with the AltiVec version on my A1X1000. The converted video has green artifacts. I’ve also tried an older version, and the converted video was ok. No problem with the generic’s one. Converting avi to h264 works also. It seems to be a decoding issue with x264 video file.  Regards,

Correction to the readme. The solution for altivec binaries wasn't linker libs from 4.2.4, but using binutils 2.18 which has different internal linker scripts.

This is a different issue unrelated to the use (or non-use) of -safe 0. I'll look into it.

Paths starting with / will be translated by libunix. I'd rather not link it without that, because I find it useful. Adding ".." before the slash will work around it. 
 
I need a command line example for filter_complex. I have sent you a private message elsewhere.

Does the filter_complex option work? If I specify it by itself it says I am missing arguments. But if I give arguments it says the option is not recognised! :-? 
 
Also it doesn't accept Amiga path names. If it starts with a slash it thinks it is a volume. 
 
Errors below: 
ffmpeg_ppc: missing argument for option 'filter_complex' 
Unrecognized option 'filter_complex'

If you have a volume called data: or even file:, that is going to confuse ffmpeg because those have special meanings. As you've noticed, changing the case is a workaround. Same goes with having a volume called http:

Wed, 07 Aug 2013 21:25:22 +0000

By: Thematic (88.113.184.161)

The solution was correct but the cause was actually the exact string 'data:' (read or write, write error message is "Impossible to open the 'data' protocol for writing").

Wed, 07 Aug 2013 21:06:18 +0000

By: Thematic (88.113.184.161)

Maybe this will save somebody's hair... the Amiga volume name (first part of a path) has to have a capital first letter or it seems to not get recognized as a volume name. The error message is "No ',' delimiter in URI". 
 
I first thought it's just being case sensitive but that isn't the... situation.

@K-L 
 
I probably should have said the Unpack script is in the FFmpeg directory. One thing I hadn't noticed was that you need to set the executable flag on the files created by xdelta3-decoder, with C:Protect or DOpus. Seeing as I already have the "unpacked" binaries anyway, I wasn't aware of that until now.

Thanks BUT how are we supposed to create the Altivec version ??? I had to google about xdelta-decoder3 to find something on Aminet with a doc and even with this I could not manage to create anything. 
 
I think that even a really small AmigaOS documentation woud have been useful. 
 
BTW, why don't your create the Altivec version and then release it on OIS4Depot ?

Make a thread about it on one of the forums. No such problem here. Need more info too, like what your input file is, exactly how you're using ffmpeggui. Post on the forums.

@ktadd 
No, I'm not talking about the buffer under-run report. The resulting file is somehow corrupt. If you create a file with mp3 audio, and then use "Input File Info" (on FFMpegGUI) to examine the file, the duration is reported as 00:00:00.00 and the bitrate is enormous (in the test I just ran off, I created with with 2040, but info reports it as "bitrate: 2147483 kb/s". DVPlayer & MPlayer can play the file, but can't seek.

Opps, sorry.  The last comment was meant for when using with ffmpegGUI. 
Still the ffmpeg reported error about buffer issues when encoding to mp3 can be safely ignored.

@DavyW 
Read the requester that is displayed at the end when encoding to mp3 audio.  It's a bug with the library used to encode mp3. It can safely be ignored as pointed out in the requester.  Unless of course your getting a different requester?  Post to Amigans or Amigaworld if that's the case.

ffmpeg is really simply to compile using the original sources from main page. 
but you need a working gg installed or (better..) a cross compiler. 
if you need the sources just send a mail

I though you'd have the source included. The real nice thing is that you can use
