Rostislav Pehlivanov	5fd4cffe32	lavc: add a librsvg rasterization library wrapper Enables rendering of SVG images. This is possible since SVG images still contain and specify the dimensions in pixels to which they've been drawn to and thus enable browsers to display them without any external data. Users can still override and generate images with arbitrary resolutions. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago

Daniil Cherednik	9c4e69b8ea	avcodec/dcaenc: Do not abort process in case of bitrate deficit Old behaviour - abort if at least one subband has 1bit quantizer and consumed_bits still greater than frame_bits size. It was a bit strange - we still could reduce bits consumption by reducing SNR for other subbands. Same strange logic with upper threshold - stop bits allocation if at least one subband reach 26bits. New behaviour - if consumed_bits greater than frame_bits and all subbands has 1 bit quantizer we restart bits allocation and allow zero subbands.	8 years ago

wm4	532b23f079	videotoolbox: add hwcontext support This adds tons of code for no other benefit than making VideoToolbox support conform with the new hwaccel API (using hw_device_ctx and hw_frames_ctx). Since VideoToolbox decoding does not actually require the user to allocate frames, the new code does mostly nothing. One benefit is that ffmpeg_videotoolbox.c can be dropped once generic hwaccel support for ffmpeg.c is merged from Libav. Does not consider VDA or VideoToolbox encoding. Fun fact: the frame transfer functions are copied from vaapi, as the mapping makes copying generic boilerplate. Mapping itself is not exported by the VT code, because I don't know how to test.	8 years ago
