[FFmpeg-devel] [PATCH 0/3] avformat/matroska: add ordered-chapter parsing

Hi, This short series lays the groundwork for ordered-chapter playback in Matroska, fixing trac ticket #3123. To start with I added type defs and parsing for editions. I stay compatible with the existing logic by fetching the chapters from all editions thereby flattening the structure. I think

Re: [FFmpeg-devel] [PATCH] avcodec/nvenc: High bit depth encoding for HEVC

Hi Roman and Timo, Timo is right. As a general rule, hybrid video coding standards allow encoders to take advantage of encoding a 8-bit input as 10-bit due to the interpolation filters (inter and intra) and transform coding at 10-bit depth. This can generate a better prediction and reduced bandi
