* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16
| | | | | | | | This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>

* avformat/hashenc: Deduplicate AVClassesAndreas Rheinhardt2021-07-08
| | | | | | | | The child_class_next API relied on different (de)muxers to use different AVClasses; yet this API has been replaced by child_class_iterate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat: remove avio_flush() calls from the end of write_packet functionsMarton Balint2020-01-07
| | | | | | | | | | | | | | | | Removing explicit avio_flush() calls helps us to buffer more data and avoid flushing the IO context too often which causes reduced IO throughput for non-streamed file output. The user can control flushing behaviour at the end of every packet using the -flush_packets option, the default typically means to flush unless a non-streamed file output is used. Therefore this change should have no adverse effect on streaming, even if it is assumed that a new packet has a clean buffer so small seekbacks within the output buffer work even when the IO context is not seekable.

* avformat: remove unneeded avio_flush() calls from the end of write_trailer ↵Marton Balint2020-01-07
| | | | | | | functions The IO context is always flushed by libavformat/mux.c after write_trailer is called, so this change should have no effect at all.

* avformat/hashenc: use an array of hashesMoritz Barsnick2019-09-20
| | | | | | | | | | | | | | | | | Only the first element of the array is used currently, the other elements are in preparation for a new muxer calculating multiple hashes. Also move alloc/init code from the write_header() functions to dedicated init() functions, and the cleanup code from the write_trailer() functions to dedicated deinit() functions. hash_free() and framehash_free() turn out to be identical here, but will differ in the subsequent commit, so they are not consolidated.
