2014-12-04vp9_ethread: the tile-based multi-threaded encoderYunqing Wang
Currently, VP9 supports column-tile encoding, which allows a frame to be encoded in multiple column tiles independently. The number of column tiles are set by encoder option "--tile-columns". This provides a way to encode a frame in parallel. Based on previous set of patches, this patch implemented the tile- based multi-threaded encoder. Each thread processes one or more tiles. Usage: For HD clips: --tile-columns=2 --threads=1/2/3/4 While using 4 threads, tests showed that the encoder achieved 2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at realtime speed 5.

2014-11-13Prepare for dynamic frame resizing in the recode loopAdrian Grange
Prepare for the introduction of frame-size change logic into the recode loop. Separated the speed dependent features into separate static and dynamic parts, the latter being those features that are dependent on the frame size. Change-Id: Ia693e28c5cf069a1a7bf12e49ecf83e440e1d313
2014-11-10Vidyo: Support for one-pass rc-enabled SVC encoderDeb Mukherjee
Adds support for one-pass rc-enabled SVC encoder with callbacks for getting per-layer packets. - the callback function registration is implemented as an encoder control function. - if the callback function is not registered, the old way of aggregating packets with superframe will take effect. - one more control function “VP9E_GET_SVC_LAYER_ID” has been implemented to get the temporal/spatial id from the encoder within the callback. This can be used to get the ids to put on RTP packet. Change-Id: I1a90e00135dde65da128b758e6c00b57299a111a
2014-10-27Add a new control of golden frame boost in CBR modeYaowu Xu
0 means that golden boost is off, and uses average frame target rate, a non-zero number means the percentage of boost over average frame bitrate is given initially to golden frames in CBR mode. Change-Id: If4334fe2cc424b65ae0cce27f71b5561bf1e577d

2014-10-20Extend --auto-alt-ref so it can enable multi-alt ref.Paul Wilkins
Extend --auto-alt-ref from parameter so we can use it to turn multi-arf on and off from the command line. For now the range is 0-off, 1-on, 2-multi-arf on. Rename play_alternate to enable_auto_arf Change-Id: Id7b64407cfbe76ba0090a83b588a03e22a240386
2014-10-16[spatial svc]Another workaround to avoid using prev_miMinghai Shang
We encode a empty invisible frame in front of the base layer frame to avoid using prev_mi. Since there's a restriction for reference frame scaling factor, we have to make it smaller and smaller gradually until its size is 16x16. Change remerged. Change-Id: I9efab38bba7da86e056fbe8f663e711c5df38449

2014-09-11Adds high bitdepth transform functions and testsDeb Mukherjee
Adds various high bitdepth transform functions and tests. Much of the changes are related to using typedefs tran_low_t and tran_high_t for the final transform cofficients and intermediate stages of the transform computation respectively rather than fixed types int16_t/int. When vp9_highbitdepth configure flag is off, these map tp int16_t/int32_t, but when the flag is on, they map to int32_t/int64_t to make space for needed extra precision.

2014-08-28Removing alg_priv from vpx_codec_priv struct.Dmitry Kovalev
In order to understand memory layout consider the declaration of the following structs. The first one is a part of our API: struct vpx_codec_ctx { // ... struct vpx_codec_priv *priv; }; The second one is defined in vpx_codec_internal.h: struct vpx_codec_priv { // ... }; The following struct is defined 4 times for encoder/decoder VP8/VP9: struct vpx_codec_alg_priv { struct vpx_codec_priv base; // ... }; Private data allocation for the given ctx: struct vpx_codec_ctx *ctx = <get> struct vpx_codec_alg_priv *alg_priv = <allocate> ctx->priv = (struct vpx_codec_priv *)alg_priv; The cast works because vpx_codec_alg_priv has a vpx_codec_priv instance as a first member 'base'.

2014-08-25[spatial svc]Multiple frame context featureMinghai Shang
We can use one frame context for each layer so that we don't have to reset the probs every frame. But we can't use prev_mi since we may drop enhancement layers. So we have to generate a non vp9 compatible bitstream and modify it in the player. 1. We need to code all frames as invisible frame to let prev_mi not to be used. But in the bitstream we need to code the show_frame flag to 1 so that the publisher will know it's supposed to be a visible frame. 2. In the player we need to change the show_frame flag to 0 for all frames. Then add an one byte frame into the super frame to tell the decoder which layer we want to show.

2014-08-22Choosing GOOD mode by default.Dmitry Kovalev
This patch fixes slow first pass problem. Mode could only be determined from the deadline value during frame encode call. Unfortunately, we use mode value before any encode calls during the first pass encoding (see set_speed_features() logic). The mode for the first pass must be different from BEST to make first pass fast. Change-Id: I562a7d32004ff631695d91c09a44d8a9076fd6b5
