| * swscale: error dithering for 16/9/10-bit to 8-bit.Ronald S. Bultje2011-07-113-49/+160
| | | | | | | | Based on a somewhat similar idea in FFmpeg's swscale copy.
| * swscale: fix overflow in 16-bit vertical scaling.Ronald S. Bultje2011-07-111-9/+9
| | | | | | | | | | | | We operated on 31-bits, but with e.g. lanczos scaling, values can add up to beyond 0x80000000, thus leading to output of zeroes. Drop one bit of precision fixes this.
| * swscale: fix crash in 8-bpc bilinear output without alpha.Ronald S. Bultje2011-07-111-1/+2
| | | | | | | | | | | | We accessed the alpha array even it wasn't used and didn't exist, hence leading to a NULL pointer segfault. (cherry picked from commit bf2cba453244a74331238a472fe0e309f116f4d9)
| * swscale: fix 16-bit scaling when output is 8-bits.Ronald S. Bultje2011-07-112-13/+13
| | | | | | | | | | We would use the second half of the U plane buffer, rather than the V plane buffer, to output the V plane pixels.

| * swscale: for >8bit scaling, read in native bit-depth.Ronald S. Bultje2011-07-115-63/+11
| | | | | | | | | | | | For 9/10bit, it means we don't have to upscale to 16bit before actual scaling or pixel format conversion, and thus a performance gain.

| | | | | | | | | | | | | | | | | | This means that precision is retained when scaling between sample formats with >8 bits per component (48bit RGB, 16bit grayscale, 9/10/16bit YUV).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since avfilter_graph_parse() creates the "[in]" inout for the first unlabelled input pad, it is expected that it will create an "[out]" inout for last unlabelled output pad, even in the case where it cannot find any open input pad with that name. This change removes the check on the existence of an open input pad named "out", so it simplifies the checked condition while implementing a more intuitive behavior.

| | | | | | | | | | | | | | | | | | | | | | | | In testing, the file output plugin gave a max buffer size of about 20 million frames, which is way more than what is really needed and causes a memory allocation error on my system.

| | | | | | | | | | | | | | | | | | | | buffer_size/4 is the value used by aplay. This fixes output to null devices, e.g. writing ALSA output to a file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set DV packet durations using fields_per_frame. This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet(). Since MPEG-2 seems to work fine this done only for DV.
