[FFmpeg-devel] [PATCH] avcodec/exr: preserve half-float NaN bits and add fate test

From: Mark Reid Hi, This patch handles NaNs more like the offical implentation handles them, preserving the original bits. https://github.com/AcademySoftwareFoundation/openexr/blob/RB-2.5/IlmBase/Half/toFloat.cpp#L111 It also adds a fate test that is a 256x256 exr containing all possible 16bit

Re: [FFmpeg-devel] Add RTSP range header

Whoops, looks like Gmail sent the .patch file attachment as application/octet-stream ... I must say, the ffmpeg binary is much more lenient in its input than the ffmpeg-devel mailing list :) Let me try again with Thunderbird, and a .txt file. Thanks all, Yakov On 11/22/20 11:21 AM, Yakov Oks

[FFmpeg-devel] Add RTSP range header

Hi all, While working to get historical video off a DVR, I found the lack of a customizable Range: header for RTSP video frustrating (as, apparently, have others on StackOverflow and the Trac wiki, #6659). One user mentionedhaving made a custom patch, but didn't post it; so, I decided to make one.
