didn't have the patchst anymore and already processed comments in later patches, so 02/35 and 05/35 became out of 33. Noticed that too late. Hope that doesn't confuse anything. Else we'll get it on -v2 of this series (which there will certainly be), where i think i'll throttle sending a bit (someho

2021-06-07 Thread Diederick Niehorster
avdevice/dshow is a realtime device and as such does not support seeking. Therefore, its demuxer format should define the AVFMT_NOBINSEARCH, AVFMT_NOGENSEARCH and AVFMT_NO_BYTE_SEEK flags. With these flags set, attempting to seek (with e.g. avformat_seek_file()) correctly yields -1 (operation no
