* avcodec: add a subcharenc mode that disables UTF-8 checkwm42018-03-251-1/+1
| | | | | | | | This is for applications which want to explicitly check for invalid UTF-8 manually, and take actions that are better than dropping invalid subtitles silently. (It's pretty much silent because sporadic avcodec error messages are so common that you can't reasonably display them in a prominent and meaningful way in a application GUI.)

* avcodec/mediacodecdec: add delay_flush optionAman Gupta2018-03-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The default behavior of the mediacodec decoder before this commit was to delay flushes until all pending hardware frames were returned to the decoder. This was useful for certain types of applications, but was unexpected behavior for others. The new default behavior with this commit is now to execute flushes immediately to invalidate all pending frames. The old behavior can be enabled by setting delay_flush=1. With the new behavior, video players implementing seek can simply call flush on the decoder without having to worry about whether they have one or more mediacodec frames still buffered in their rendering pipeline. Previously, all these frames had to be explictly freed (or rendered) before the seek/flush would execute. The new behavior matches the behavior of all other lavc decoders, reducing the amount of special casing required when using the mediacodec decoder.

* avcodec/nvenc: Declare support for P016Philip Langdale2018-03-021-1/+1
| | | | | | | | | | | | | | | | | | | nvenc doesn't support P016, but we have two problems today: 1) We declare support for YUV444P16 which nvenc also doesn't support. We do this because it's the only pix_fmt we have that can approximate nvenc's internal format that is YUV444P10 with data in MSBs instead of LSBs. Because the declared format is a 16bit one, it will be preferrentially chosen when encoding >10bit content, but that content will normally be YUV420P12 or P016 which should get mapped to P010 and not YUV444P10. 2) Transcoding P016 content with nvenc should be possible in a pure hardware pipeline, and that can't be done if nvenc doesn't say it accepts P016. By mapping it to P010, we can use it, albeit with truncation. I have established that swscale doesn't know how to dither to 10bits so we'd get truncation anyway, even if we tried to do this 'properly'.

| * lavc: Add support for increasing hardware frame pool sizesMark Thompson2018-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | AVCodecContext.extra_hw_frames is added to the size of hardware frame pools created by libavcodec for APIs which require fixed-size pools. This allows the user to keep references to a greater number of frames after decode, which may be necessary for some use-cases. It is also added to the initial_pool_size value returned by avcodec_get_hw_frames_parameters() if a fixed-size pool is required.

* | avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>. Merges Libav commit 47687a2f8aca3f65b6fdd117b1cb66a7409a7fd1.

* | vp9: use superframe split BSFwm42017-11-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | webm usually has invisible superframes merged with normal frames. (vpxenc muxes them in this form, which is evidence enough that this is the standard webm packet format. It's rather unclear whether ffmpeg is even allowed to remux them with split packets.) The vp9 decoder needs them to be in separate packets for multithreading to work. Add the BSF to the decoder, so the conversion happens automatically. This contains the important part of fa1749dd34c55fb9, which was apparently skipped in commit d417e95af76. This restores Libav API compatibility.

* | avcodec: Implement mpeg4 nvdec hwaccelPhilip Langdale2017-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was predictably nightmarish, given how ridiculous mpeg4 is. I had to stare at the cuvid parser output for a long time to work out what each field was supposed to be, and even then, I still don't fully understand some of them. Particularly: vop_coded: If I'm reading the decoder correctly, this flag will always be 1 as the decoder will not pass the hwaccel any frame where it is not 1. divx_flags: There's obviously no documentation on what the possible flags are. I simply observed that this is '0' for a normal bitstream and '5' for packed b-frames. gmc_enabled: I had a number of guesses as to what this mapped to. I picked the condition I did based on when the cuvid parser was setting flag. Also note that as with the vdpau hwaccel, the decoder needs to consume the entire frame and not the slice.
* | avcodec: Implement mpeg1 nvdec hwaccelPhilip Langdale2017-11-201-1/+1
| | | | | | | | | | Once I remembered that there's a separate decoder type for mpeg1, even though params struct is shared with mpeg2, everything worked.
* | avcodec: Implement mpeg2 nvdec hwaccelPhilip Langdale2017-11-181-1/+1
| | | | | | | | | | | | This is mostly straight-forward. The weird part is that it should just work for mpeg1, but I see corruption in my test cases, so I'm going to try and fix that separately.

| | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, which allows the API user to query the required AVHWFramesContext parameters. This also reduces code duplication across the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses the new API function. It takes care of initializing the hw_frames_ctx if needed, and does additional error handling and API usage checking. Support for VDA and Cuvid missing.
