* 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
| | | | | | | | | Each frame is now padded with 0 values if not enough samples are present, and all frames are guaranteed to have exactly 1 << (venc->log2_blocksize[1] - 1) samples. Signed-off-by: Tyler Jones <tdjones879@gmail.com> Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* 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>

| | | | | | Uses the just-added ALLOW_PROFILE_MISMATCH flag. (cherry picked from commit 7acb90333a187b0e847b66f9d3511245423dc0ce)

* vaapi_encode: Use gop_size consistently in RC parametersMark Thompson2017-06-14
| | | | | | | | | | The non-H.26[45] codecs already use this form. Since we don't currently generate I frames for codecs which support them separately to IDR, the p_per_i variable is set to infinity by default so that it doesn't interfere with any other calculation. (All the code for I frames still exists, and it works for H.264 if set manually.) (cherry picked from commit 6af014f4028238b4c50f1731b3369a41d65fa9c4)
