For some reason it seems the Docker version of ffmpeg 3.4 uses "optimal"
Huffman tables (despite not being default), which cause ffmpeg to crash
when mjpeg encoder is encoding artwork jpeg's
rescaling, meaning we can do without parallel ffmpeg interfaces.
This also moves artwork rescaling from libswscale to libavfilter, which
seems to fix a problem with PNG rescaling.
* [config] Added support for libav/ffmpeg dual installs
Reordered CPPFLAGS/LIBS so that library flags (includes etc) appear
ahead of prefix/global directives and the correct headers/libraries
are checked (if symbols are defined in alternative libraries).
Updated libav checks to use header declaration checks
rather than link checks (so differences between
libav/ffmpeg can be correctly found), and updated code references
to use new defines. Added support the alternate pkg-config
package names for libav. Updated ffmpeg vs libav check
to check MICRO version number (>=100 for ffmpeg). Simplified
resulting configure script by using a function to merge
CPPFLAGS variables.
* [config] Use FORKED_OPTS prefix for libevent_pthreads option
* [config] Add --with-libav option to select libav even if ffmpeg present
- Added custom checks for libraries and pkgconfig modules that test library
presence with additional checks for use of headers and functions with
given options. Also support correct additional feature library checks
using provided flags.
- Added custom enable/disable feature macros to simplify their use.
- Use custom CFLAGS and LIBS variables for Makefiles to simplify maintenance.
- Update many feature checks from platform to function.
- Streamline many function checks.
- Correctly check gnutls, gcrypt and gpg-error libraries.
- Fix chromecast and spotify config and compile on FreeBSD
- Added inotify, signalfd and kqueue, and byte swap checks.
- Many clarifications of error messages.
- Correct json-c checks to properly use supplied CFLAGS.
- Correct many quoting inconsistencies
- Use __DATE__ in place of BUILDDATE
- Use full path for gperf and antlr3
- Remove unnecessary CFLAGS
- Added tests for pthread_setname_np parameters
- Added tests for clock_gettime and timer_settime
- Added tests for time.h
- Test if pthread, dl and rt libs are required/available.
- Updated checks for libunistring
Added a real config.rpath
Fixed build date calc for BSD
Require some needed headers at configure time
Correctly check libav functions using pkg-config flags
Made checks for some Linux features available on other ports
Fixed porting issue with antlr dep files
Added default HOST_NAME_MAX if not defined
Added missing libav header
It seems ffmpeg/libav reads a file type like Monkey's audio in large
chunks, so that each packet must be passed to the decoder multiple
times. The decoder will return 0 until the packet is completed. This
change makes forked-daapd able to deal with a return value of 0.
Also includes the skeleton for perhaps supporting video in the future. Adds more fine-grained
ffmpeg/libav compability checks. Dependency on libavresample/libswresample exchanged with
dependency on libavfilter, which seems more versatile.
