FFmpeg + FFplay git-7df9937 (29.01.2012)
I. FFmpeg
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.
1. Usage
a) convert avi video file to mpg with audio bitrate 128kb and video bitrate
1024kb:
ffmpeg -i test.avi -acodec mp2 -b:a 128k -vcodec mpeg1video -b:v 1024k out.mpg
b) convert wmv video file to avi (divx) with audio bitrate 256kb and video
bitrate 1024kb:
ffmpeg -i test.wmv -acodec libmp3lame -b:a 256k -vcodec msmpeg4v2 -b:v 1024k
out.avi
c) convert mkv video file to avi (h264) with audio bitrate 256kb and video
bitrate 1024kb:
ffmpeg -i test.wmv -acodec libmp3lame -b:a 256k -vcodec libx264 -b:v 1024k
out.avi
d) convert jpeg2000 image to bmp:
ffmpeg -i test.jp2 test.bmp
e) convert flac audio file to wma:
ffmpeg -i test.flac test.wma
f) grab the network stream (requires correct assign to amitcp package):
assign amitcp: <path>:amitcp
ffmpeg -i [http/mmsh/mmst/rtp/rtmp/rtsp]://x.x.x.x/file.ra -acodec copy out.ra
II. FFplay
There is also an FFplay video player included in the archive. FFplay can
play/show
any multimedia file type like avi/mov/asf/wmv/mkv/rmv/mp3/ogg/wma/jpg/jp2/png
etc.
1. Amiga related features
a) built-in GUI
ffplay -gui [1/2] <file>
-gui 0 - disable
-gui 1 - normal
-gui 2 - glued (default)
SF = skip frame
SS = save screenshot
CA = cycle audio tracks
CV = cycle video tracks
CS = cycle subtitle tracks
AW = show/hide audio wave
FS = full screen/window mode
I = about requester
Q = quit
The "Load File" gadget works via ARexx script, so:
- RexxMast must be run before FFplay
- "ffplay_loadfile.rexx" script must be located in "S:" dir
- "RX" command must be located in "SYS:RexxC" dir
- "Wait" command must be located in "C:" dir
- FFplay must be located in "C:" dir (this can be changed, read bolow)
The "ffplay_loadfile.rexx" script can be modified to for example enable
framedrop option,
select the default dir where the requester will be opened etc.:
"Address Command 'Run <>NIL: C:FFplay -gui 2 -framedrop -quiet DH1:Movies'"
The GUI can be opened at (x,y) position on the screen with
-gui_x <x>
-gui_y <y>
options.
b) Arexx port
rexxmast
rx "ADDRESS FFPLAY_AREXX <COMMAND>"
available commands:
QUIT, PAUSE, AUDIOWAVE, FULLSCREEN, BACKWARD, FORWARD, FBACKWARD, FFORWARD,
SKIPFRAME, SCREENSHOT, CYCLEAUDIO, CYCLEVIDEO, CYCLESUBTITLE, ABOUT,
VOLMIN, VOLHALF, VOLMAX, HELP
c) Workbench support (inc. tooltypes and def_icons)
switchable tooltypes can be set to 1/0 or ON/OFF
available tooltypes:
WIDTH=[NUMBER]
HEIGHT=[NUMBER]
BYTES=[ON/OFF]
NODISP=[ON/OFF]
GENPTS=[ON/OFF]
DRP=[ON/OFF]
LOOP=[NUMBER/-1]
FRAMEDROP=[ON/OFF]
AUDIOVIS=[1/2]
AST=[NUMBER]
SST=[NUMBER]
VST=[NUMBER]
FAST=[ON/OFF]
LOWRES=[1-5]
FULLSCREEN=[ON/OFF]
AUDIO=[ON/OFF]
SUBTITLES=[ON/OFF]
VIDEO=[ON/OFF]
AUTOEXIT=[ON/OFF]
SKIPFRAME=[16/32]
DITHER=[GRAY/HICOLOR/TRUECOLOR]
SYNC=[AUDIO/VIDEO/EXT]
STARTPATH=[PATH]
AUDIOBLOCK=[ON/OFF]
EXITONKEYDOWN=[ON/OFF]
EXITONMOUSEDOWN=[ON/OFF]
GUI_X=[NUMBER]
GUI_Y=[NUMBER]
GUI=[0/1/2]
MOUSEWHEEL=[1/2]
VOL=[1-11]
some tooltypes have a different names compared to the command line options:
"-x" = WIDTH
"-y" = HEIGHT
"-fs" = FULLSCREEN=ON
"-an" = AUDIO=OFF
"-sn" = SUBTITLES=OFF
"-vn" = VIDEO=OFF
d) file requester
2. Usage
a) while playing
q, ESC quit
f, ENTER toggle full screen
p, SPACE pause
a cycle audio channel
v cycle video channel
t cycle subtitle channel
w show audio waves
s activate frame-step mode
x save screenshot
i show about window
left/right seek backward/forward 15 seconds
down/up seek backward/forward 1 minute
</> increase/decrease audio volume
LMB click seek to percentage in file corresponding to fraction of
width
RMB click hide/show mouse pointer
b) default directory
* from CLI
ffplay <no file/no dir> - "ffplay_startpath" env variable will be read and if
the dir set in
the variable exists, requester will be opened in that dir.
in case there is no "ffplay_startpath" env variable or the dir doesn't exist
then the
requester will opened in the current dir.
ffplay <dir> - the requester will be opened in the <dir>, even if
"ffplay_startpath"
variable exists.
* from WB
ffplay's icon clicked - the tooltype "STARTPATH" will be read from ffplay's icon
and if the dir
does exist, the requester will be opened there, otherwise the requester will be
opened in the
current WB directory.
c) misc
* mousewheel
ffplay -mousewheel 1 <file> - use mousewheel for stream seeking
ffplay -mousewheel 2 <file> - use mousewheel for audio volume change (default)
* audio volume
ffplay -vol 1 <file> - set the audio volume to minimum
ffplay -vol 11 <file> - set the audio volume to maximum (default)
* autoexit
ffplay -autoexit <file> - exit player when stream reaches the end
* loop
ffplay -loop -1 <file> - loop the stream infinite number of times
ffplay -loop 2 <file> - loop the stream only one time
* disable audio, video or subtitles
ffplay -an <file> - disable audio playback
ffplay -vn <file> - disable video playback
ffplay -sn <file> - disable displaying of subtitles
* dither
ffplay -dither gray <file> - play the video on 8-bit screen
ffplay -dither hicolor <file> - play the video on 15/16-bit screen
ffplay -dither truecolor <file> - play the video on 24/32-bit screen
* quiet
ffplay -quiet <file> - do not output FFmpeg's warnings/messages to the console
* realtime video filter fun
ffplay -vf hflip <file>

ffplay -vf mp=down3dright <file>
ffplay -vf mp=boxblur=6:6 <file>
ffplay -vf mp=noise=25 <file>
* network streaming (test stream)
ffplay mmsh://208.75.229.58/1tv
3. Notes
a) for a playback on slow systems try to use a combination of these options:
ffplay -quiet -an -framedrop -lowres [1/2/3] -skipframe [16/32] -dither
[gray/hicolor] <file>
b) IMPORTANT: Under WinUAE copy the "env/ahi_minbufflen" file to "ENV:" and
"ENVARC:" before using
FFplay and set the video memory to at least 16MB.
c) some people seems to get "ffplay failed returncode 161" error message while
using ffplay
under DOpus 5.x. I can't reproduce this on my system, but I got a report that
this workround
happen to fix the problem:
{AmigaDOS} Run >NIL: C:FFplay {f}
Thanks to Bernd Roesch for his bugfixed/improved ixemul/SDL libraries
and Matt Hey for optimized 68060 asm routines.
Installation:
copy "bin/ffmpeg[040fpu/060fpu]" to "c:ffmpeg"
copy "bin/ffplay[040fpu/060fpu]" to "c:ffplay"
copy "bin/ffprobe[040fpu/060fpu]" to "c:ffprobe"
copy "env/*" to "env:" and "envarc:"
copy "rexx/ffplay_loadfile.rexx" to "s:ffplay_loadfile.rexx"
Requirements:
68020+ with FPU
64MB of RAM
AHI
CyberGfx or Picasso96
ixemul.library v63+
Changes:
11.02.2012
- fixed "skip one frame" mode ("SF" button / "s" key)
