FFmpeg is a complete, cross-platform solution to record,
convert and stream audio and video. FFmpeg can also convert from
any sample rate to any other and resize video on the fly with a high
quality polyphase filter.

Thx!
Any chance for a warpos version? :)

Can this convert mpegs/avi's to anim5?

Sorry, no. I have no PPC hardware to test the builds, no WarpOS cygwin-hosted
crosscompiler and it would require too much work to recompile again all of the
external libs for PPC.

Not yet, maybe in the future. ;) However I would prefere so see a decoder
implemented first. :) (right now there is only IFF ILBM decoder with HAM6/8
support)

I think this could be even more interesting when NatAmi will hit the "market", so we could test its hopefully superior CPU horsepower.

That's where VBCC comes in handy! :)

A4000 / Apollo 4060 @ 90 MHz / 640 MB FastMem
playing some clips with FroggerNG ...
Hmmm .... I will try FFmpeg/FFplay this evening.

It would be interesting to see how good/bad FFplay behaves on your hardware.
Please note that FroggerNG have by default enabled frame skipping, while FFplay not.
Maybe you can record a video with two tests:
I. with audio
FroggerNG file.mpg/file.divx AUTOSTART
FFplay -framedrop file.mpg/file.divx
and
II. without audio
FroggerNG NOSKIP NOAUDIO AUTOSTART file.mpg/file.divx
FFplay -an file.mpg/file.divx
it would be also interesting to see how much lowres speedups decoding:
FFplay -an -lowres 1 file.mpg/file.divx

Great looking desktop you have there and may I ask what music is playing in that vid?

It's a classical MOD called "Guitar Slinger", well, it's actually an arrangement I believe, but it sounds almost the same.

Firstly, thanks for the port, its very welcome.
By the quote above does this mean I can take say an mpeg4 and turn it into a ham8 anim file for playback on my a1200?

No. Three is no IFF ANIM encoder in FFmpeg, so this is not possible.

Thank you for your time on this software.
I have noticed that some mpegs I have above 320x240 play back fine with no sync issues between the sound/graphics
Other mpegs which are lower resolutions struggle to play back.
I would have thought the Amiga would be working harder to playback the higher resolution video but it seems there are other factors to peformance: maybe video bitrate, buffer size, codec type etc
So it would be nice to convert videos with FFMpeg with the optimal settings for an 060 CPU.
Does anyone have experience on what command line options to use to convert videos for use on the Amiga? Any help would be appreciated from someone who has experience with FFMpeg.

For ffmpeg that *should* be possible. For ffplay, not really. SDL and Warpos are not good friends.

I have no idea, but maybe H261 would be ok for 030 or 040:
ffmpeg -i file.mpg -vcodec h261 -r 15 -s 176x144 -sws_flags lanczos -acodec pcm_u8 -ar 22050 file.avi
the fastest would be of course rawvideo:
ffmpeg -i file.mpg -vcodec rawvideo -sws_flags lanczos -r 15 -s 176x144 -acodec pcm_u8 -ar 22050 file.avi
