* Add an AAC encoder by using the libvo-aacenc libraryMartin Storsjö2011-04-114-2/+132
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* g722: Return 8 bits per sample for g722 in av_get_bits_per_sampleMartin Storsjö2011-04-111-0/+1
| | | | | | | | This fixes a failing assert in ff_raw_read_header (in fate-g722dec-1), where bits_per_coded_sample is set using this function and is required to have a positive value. Signed-off-by: Martin Storsjö <martin@martin.st>

* pthread: validate_thread_parameters() ignored slice-threading being ↵Alexander Strange2011-04-091-1/+1
| | | | | | | | | | | | intentionally off The thread_type API allows you to request only FF_THREAD_FRAME (instead of FRAME | SLICE), but it was being ignored. We don't implement both of them at the same time, so there isn't an effect on current codecs, except that you can request no kinds of threading now (a bit useless). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* Remove unnecessary parameter from ff_thread_init() and fix behaviorAlexander Strange2011-04-054-11/+10
| | | | | | | | | | | thread_count passed to ff_thread_init() is only used to set AVCodecContext. thread_count, and can be removed. Instead move it to the legacy implementation of avcodec_thread_init(). This also fixes the problem that calling avcodec_thread_init() with pthreads enabled did not set it since ff1efc524cb3c60f2f746e3b4550bb1a86c65316.

* Revert "aac_latm_dec: use aac context and aac m4ac"Janne Grunau2011-04-051-2/+2
| | | | | This reverts commit 36864ac3540445c513484017aa9927e942fac24a since it breaks LATM decoding in ffplay.

* ac3enc: use generic fixed-point mdctMans Rullgard2011-04-035-422/+21
| | | | | | | | This makes the AC3 encoder use the shared fixed-point MDCT rather than its own implementation. The checksum changes are due to different rounding in the MDCT. Signed-off-by: Mans Rullgard <mans@mansr.com>

* lavc: mark hurry_up for removal on next major bumpAnton Khirnov2011-04-0214-10/+61
| | | | | It has been deprecated for about five years, skip_idct/skip_frame should be used instead.
