| | | | | | 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: Separate copying audio samples from windowingTyler Jones2017-06-151-44/+32
| | | | | | | | | | | | 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>

| | | | (cherry picked from commit 66aa9b94dae217a0fc5acfb704490707629d95ed)
* vf_hwmap: Add reverse mapping for hardware framesMark Thompson2017-06-141-7/+61
| | | | | | | | | | | This is something of a hack. It allocates a new hwframe context for the target format, then maps it back to the source link and overwrites the input link hw_frames_ctx so that the previous filter will receive the frames we want from ff_get_video_buffer(). It may fail if the previous filter imposes any additional constraints on the frames it wants to use as output. (cherry picked from commit 81a4cb8e58636d4efd200c2b4fec786a7e948d8b)
* vf_hwmap: Add device derivationMark Thompson2017-06-141-18/+49
| | | | | | | Also refactor a little and improve error messages to make failure cases easier to understand. (cherry picked from commit 38cb05f1c89cae1862b360d4e7e3f0cd2b5bbb67)
* hwcontext: Improve allocation in derived contextsMark Thompson2017-06-145-3/+26
| | | | | | | | | Use the flags argument of av_hwframe_ctx_create_derived() to pass the mapping flags which will be used on allocation. Also, set the format and hardware context on the allocated frame automatically - the user should not be required to do this themselves. (cherry picked from commit c5714b51aad41fef56dddac1d542e7fc6b984627)

| | | | | | Factorises out existing surface initialisation code to reuse. (cherry picked from commit eaa5e0710496db50fc164806e5f49eaaccc83bb5)
* hwcontext: Add frame context mapping for nontrivial contextsMark Thompson2017-06-142-1/+13
| | | | | | | | | Some frames contexts are not usable without additional format-specific state in hwctx. This change adds new functions frames_derive_from and frames_derive_to to initialise this state appropriately when deriving a frames context which will require it to be set. (cherry picked from commit 27978155bc661eec9f22bcf82c9cfc099cff4365)
* hwcontext_qsv: Support derivation from child devicesMark Thompson2017-06-141-29/+84

* ffmpeg: Support setting the hardware device to use when filteringMark Thompson2017-06-144-2/+37
| | | | | | | | This only supports one device globally, but more can be used by passing them with input streams in hw_frames_ctx or by deriving new devices inside a filter graph with hwmap. (cherry picked from commit e669db76108de8d7a36c2274c99da82cc94d1dd1)

* vaapi_encode: Use gop_size consistently in RC parametersMark Thompson2017-06-143-6/+5
| | | | | | | | | | 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)
