Re: [FFmpeg-devel] [FFmpeg-user] ffplay.exe leaves fullscreen mode and iconifies when losing focus

Dear all, I could identify the reason for the behaviour. In FFmpeg-master\libavdevice\gdigrab.c, gdigrab_region_wnd_init() *WS_POPUP *is used for CreateWindowEx(), Why? WS_POPUP is not expected for main windows. Is it possible to fix this? Best regards,     Norbert /**  * Initialize the regio

[FFmpeg-devel] [PATCH 1/8] avutil/timecode: fix av_timecode_get_smpte_from_framenum with 50/60 fps

SMPTE 12M timecode can only count frames up to 39, because the tens-of-frames value is stored in 2 bit. In order to resolve this 50/60 fps SMPTE timecode is using the field bit (which is the same bit as the phase correction bit) to signal the least significant bit of a 50/60 fps timecode. See SMPTE
