Timo Rothenpieler	971351b664	avcodec/nvenc: Handle minqp-only case in set_vbr	9 years ago
Timo Rothenpieler	eae4eba9cb	avcodec/nvenc: twopass mode works in all modes	9 years ago
Timo Rothenpieler	1330a0f31f	avcodec/nvenc: Fix forcing constqp rc mode The CONSTQP enum value is 0, so this check failed for it.	9 years ago
Andrey Turkin	58c6dcb4b7	avcodec/nvenc: don't enqueue timestamps until a frame was accepted Otherwise timestamps/pending FIFOs would go out of sync if nvEncodePicture ever fails. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>	9 years ago

Andrey Turkin	cfb49fc6f7	avcodec/nvenc: replace custom FIFOs with AVFifos Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>	9 years ago
Andrey Turkin	e1691c44f0	avcodec/nvenc: combine input and output surface structures There is no point in separate structures as they have 1:1 relationship, they are always used together and they have same lifetime. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>	9 years ago
Andrey Turkin	82d705e245	avcodec/nvenc: split large functions into smaller ones Functions names and scopes are from libav. This commit basically moves code around without changing it; it shouldn't change any functionality except some small leak fixes on error paths.

Timo Rothenpieler	c921ca9b5d	avcodec/nvenc: Write buffPeriod/picTime SEI in both CBR modes	9 years ago
Timo Rothenpieler	3a9df7dfec	avcodec/nvenc: Generate bufferingPeriod/pictureTiming SEI For some unknown reason enabling these causes propper CBR padding, so as there are no known downsides just always enable them in CBR mode.	9 years ago
Timo Rothenpieler	31ce01bdb9	avcodec/nvenc: don't set profile in lossless mode	9 years ago

Anton Khirnov	871d0930d4	nvenc: support CUDA frames as input	9 years ago
Anton Khirnov	c51b2c79a7	Allow linking to CUDA dynamically instead of dlopen()ing it at runtime	9 years ago
Anton Khirnov	d005ccc630	nvenc: rename a misnamed function This function copies the encoded bistream into the caller's packet, calling it 'get_frame' is misleading.	9 years ago
Anton Khirnov	118beda355	nvenc: merge input and output surface structs An input frame always corresponds to exactly one output packet, so there is no point in complicating the situation by managing them separately.	9 years ago
Anton Khirnov	28259c13db	nvenc: factor out the pixel format list	9 years ago
Anton Khirnov	c59fec783d	nvenc: generate dts properly When there is a non-zero decoding delay due to reordering, the first dts should be lower than the first pts (since the first packet fed to the decoder does not produce any output). Use the same scheme used in mpegvideo_enc (which comes from x264 originally) -- wait for first two timestamps and extrapolate linearly to the past to produce the first dts value.	9 years ago
Anton Khirnov	9d36cab4c0	nvenc: fix encoding with B-frames When B-frames are enabled and the encoder returns success, all currently pending buffers immediately become valid and can be returned to the caller. We can only return one packet at a time, so all the other pending buffers should be transferred to a new 'ready' fifo, from where they can be returned in subsequent calls (in which the encoder does not produce any new output). This bug was hidden by the incorrect testing of the encoder return value (the return value was overwritten before it was tested).	9 years ago
Anton Khirnov	aac7d6b284	nvenc: flush the encoder before closing it, as required by the docs Otherwise, closing the encoder can crash.	9 years ago
Anton Khirnov	39571e86cb	nvenc: better error handling Return proper error codes and print more descriptive error messages.	9 years ago
