| Readme: | Short: FFmpeg 9.0.2 - ffmpeg, ffplay and ffprobe
Version: 9.0.2
Architecture: ppc-morphos
Requires: MorphOS 3.x, sdl2.library 2.32.x (latest), openssl4.library,
z.library, bz2.library, lzma.library, freetype.library,
harfbuzz.library
FFmpeg 9.0.2 for MorphOS
========================
FFmpeg records, converts and streams audio and video. This archive holds
the three command line tools:
ffmpeg convert, record and stream
ffplay media player (SDL2)
ffprobe information about files and streams
Requirements
------------
- MorphOS 3.x on a G3, G4, G5 or e5500 CPU. The AltiVec routines are used
when the CPU has AltiVec; the same binaries run without it.
- ffplay: the latest sdl2.library 2.32.11 minimun (07102026)
MorphOS port
-------------------
- Built with GCC 9.5 and the current MorphOS SDK. The static libraries
were rebuilt for this SDK where needed.
- Shared libraries: OpenSSL 4 (openssl4.library, was openssl3.library),
freetype.library (was linked in), lzma.library (new: LZMA compressed
TIFF), z, bz2 and harfbuzz.
- Library versions: libaom 3.14.1 (AV1), x265 4.2 (HEVC), x264 core 164,
dav1d 1.5.4, opus 1.5.2, libgme 0.6.4, fribidi 1.0.16.
- AltiVec is detected at run time and only used by the AltiVec routines,
so the same binaries run on CPUs with and without AltiVec.
- Network rewritten:
* sockets are handled with bsdsocket.library calls only. The 6.1 port
closed them with C library calls, which could corrupt memory and crash
NetStack, for example when quitting an HLS or DASH stream;
* a socket can be used by several tasks, so ffmpeg reads network inputs
in its threads: HTTP, HTTPS, HLS, DASH, RTMP and web radios work in
ffmpeg, ffplay and ffprobe;
* RTMP uses FFmpeg's own implementation (rtmp, rtmps, rtmpe, rtmpt)
instead of librtmp;
* HTTPS and RTMPS through OpenSSL 4.
- ffplay:
* uses the SDL2 "overlay" renderer (cgxvideo VLayer) by default: YUV
video goes straight to the overlay, the graphics card does the colour
conversion and the scaling;
* -renderer overlay|opengl|software chooses the SDL2 renderer (the
SDL_RENDER_DRIVER variable works too);
* the stream is opened and closed in the reading thread: no more freeze
when quitting a network stream;
* needs the latest sdl2.library
Libraries in this build: x264, x265, xvid, libaom, dav1d, opus, vorbis,
theora, mp3lame, libwebp, libgme, libmodplug, freetype, harfbuzz, fribidi,
libxml2, OpenSSL, zlib, bzip2, lzma, SDL2.
Usage
-----
ffplay video.mp4
ffplay "https://test-streams.mux.dev/x36xhzz/url_6/193039199_mp4_h264_aac_hq_7.m3u8"
ffmpeg -i input.mkv -c:v libx264 -preset fast -c:a aac output.mp4
ffmpeg -i "https://.../stream.m3u8" -t 60 -c copy RAM:record.ts
ffprobe video.mp4
Keep the quotes around URLs in the Shell (? and # are wildcards).
ffplay keys: q or Esc quit, f full screen, Space pause, left/right seek
-10/+10 s, up/down -1/+1 min, m mute, 9/0 volume.
On a slow CPU, ffplay -fast and -skip_loop_filter nonref (or all) make
H.264 and HEVC lighter, at the price of some artefacts.
