* avcodec: Add MediaFoundation encoder wrapperwm42020-05-19
| | | | | | | | | | | | | | | This contains encoder wrappers for H264, HEVC, AAC, AC3 and MP3. This is based on top of an original patch by wm4 <nfxjfg@googlemail.com>. The original patch supported both encoding and decoding, but this patch only includes encoding. The patch contains further changes by Paweł Wegner <pawel.wegner95@gmail.com> (primarily for splitting out the encoding parts of the original patch) and further cleanup, build compatibility fixes and tweaks for use with Qualcomm encoders by Martin Storsjö.

* doc/muxers: Document title tag for attachmentsAndreas Rheinhardt2020-05-19
| | | | | | | | | The Matroska muxer has always mapped the title tag to the FileDescription element for attachments streams since support for writing attachments was added in commit c7a63a521b5c165405e3577751d649529d09f0c5. This commit merely documents this fact. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* doc/encoders: remove unsubstantiated ffaacenc > fdk-aac claimLou Logan2020-05-08
| | | | | | | | | | | | | | | | | | | After this claim was made in e34e361 kamedo2 did an in-depth ABX test comparing these encoders: https://hydrogenaud.io/index.php?topic=111085.0 Result: FFmpeg AAC wasn't as good as libfdk_aac on average. I know some things have changed since then such as, "use the fast coder as the default" (fcb681ac) for example, so maybe the situation is different now. However, I am unaware of any recent comparison. So without any substantiation we shouldn't make such a blantant claim.

* avformat/matroskaenc: Redo handling of FlagDefaultAndreas Rheinhardt2020-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, the Matroska muxer would mark a track as default if it had the disposition AV_DISPOSITION_DEFAULT or if there was no track with AV_DISPOSITION_DEFAULT set; in the latter case even more than one track of a kind (audio, video, subtitles) was marked as default which is not sensible. This commit changes the logic used to mark tracks as default. There are now three modes for this: a) In the "infer" mode the first track of every type (audio, video, subtitles) with default disposition set will be marked as default; if there is no such track (for a given type), then the first track of this type (if existing) will be marked as default. This behaviour is inspired by mkvmerge. It ensures that the default flags will be set in a sensible way even if the input comes from containers that lack the concept of default flags. This mode is the default mode. b) The "infer_no_subs" mode is similar to the "infer" mode; the difference is that if no subtitle track with default disposition exists, no subtitle track will be marked as default at all. c) The "passthrough" mode: Here the track will be marked as default if and only the corresponding input stream had disposition default. This fixes ticket #8173 (the passthrough mode is ideal for this) as well as ticket #8416 (the "infer_no_subs" mode leads to the desired output).

* avcodec: Add explicit capability flag for encoder flushingPhilip Langdale2020-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there was no way to flush an encoder such that after draining, the encoder could be used again. We generally suggested that clients teardown and replace the encoder instance in these situations. However, for at least some hardware encoders, the cost of this tear down/replace cycle is very high, which can get in the way of some use-cases - for example: segmented encoding with nvenc. To help address that use case, we added support for calling avcodec_flush_buffers() to nvenc and things worked in practice, although it was not clearly documented as to whether this should work or not. There was only one previous example of an encoder implementing the flush callback (audiotoolboxenc) and it's unclear if that was intentional or not. However, it was clear that calling avocdec_flush_buffers() on any other encoder would leave the encoder in an undefined state, and that's not great. As part of cleaning this up, this change introduces a formal capability flag for encoders that support flushing and ensures a flush call is a no-op for any other encoder. This allows client code to check if it is meaningful to call flush on an encoder before actually doing it. I have not attempted to separate the steps taken inside avcodec_flush_buffers() because it's not doing anything that's wrong for an encoder. But I did add a sanity check to reject attempts to flush a frame threaded encoder because I couldn't wrap my head around whether that code path was actually safe or not. As this combination doesn't exist today, we'll deal with it if it ever comes up.

* pthread_frame: merge the functionality for normal decoder init and ↵Anton Khirnov2020-04-10
| | | | | | | | | | | | | | | | init_thread_copy The current design, where - proper init is called for the first per-thread context - first thread's private data is copied into private data for all the other threads - a "fixup" function is called for all the other threads to e.g. allocate dynamically allocated data is very fragile and hard to follow, so it is abandoned. Instead, the same init function is used to init each per-thread context. Where necessary, AVCodecInternal.is_copy can be used to differentiate between the first thread and the other ones (e.g. for decoding the extradata just once).
