* aarch64: vp9: Fix assembling with Xcode 6.2 and olderMemphiz2017-06-21
| | | | | | | | | | | | Properly use the b.eq/b.ge forms instead of the nonstandard forms (which both gas and newer clang accept though), and expand the register list that used a range (which the Xcode 6.2 clang, based on clang 3.5 svn, didn't support). This is cherrypicked from libav commit a970f9de865c84ed5360dd0398baee7d48d04620. Signed-off-by: Martin Storsjö <martin@martin.st>

* avcodec/decode: Update decode_simple_internal() to get the side data correctly.John Rummell2017-06-20
| | | | | | | | Use avci->last_pkt_props to get the side data. Using |pkt| doesn't work when FF_API_MERGE_SD is set, as the compressed side data is expanded into |tmp|, leaving the original |pkt| unchanged. Signed-off-by: James Almer <jamrial@gmail.com>

* vc2enc: decrease default strictness levelRostislav Pehlivanov2017-06-15
| | | | | | Given how incredibly limited the official specifications are (limiting all use to only the most common broadcasting formats), permit all supported inputs by default. This makes the encoder more useful.
* vorbisenc: Stop tracking number of samples per frameTyler Jones2017-06-15

* vorbisenc: Apply and output correct length window and mdctTyler Jones2017-06-15
| | | | | | | | | Usage of blocksize, window, mode, and mdct indexes are switched from default 0 to a default of 1 to better align with specs. A flag of 0 should correspond with short windows, a flag of 1 with long. Signed-off-by: Tyler Jones <tdjones879@gmail.com> Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* vorbisenc: Separate copying audio samples from windowingTyler Jones2017-06-15
| | | | | | | | | | | | Audio samples are shifted around when copying from the frame queue so that analysis can be done without negatively impacting calculation of the MDCT. Window coefficients are applied to the current two overlapped windows simultaneously instead of applying overlap for the next frame ahead of time. This improves readability when applying windows of varying lengths. Signed-off-by: Tyler Jones <tdjones879@gmail.com> Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com>
