video - Upper limit on FFMPEG/libx264 frame sizes? -

-

i'm trying use ffmpeg transcode video large frames (4096 x 4096). it's short video - under 2 minutes, source video file 15.8gb. (the video animation designed projected onto planetarium domes.)

the source file quicktime mov containing uncompressed photo-jpeg images (with audio, too). when tell ffmpeg transcode mov file mp4 file, says:

error while opening encoder output stream #0:0 - maybe incorrect parameters such bit_rate, rate, width or height

not helpful, yes, i've verified of parameters correct and/or defaults. in fact, if change requested output size 2048x2048, works fine. that's why suspect there's upper bound in encoder.

i kerflummoxed. suggestions result in successful transcode appreciated. (at point willing consider alternatives ffmpeg.)

the facts

i run ffmpeg script:

set srcfile=%1 set dstfile=%srcfile:.mov=.mp4%  ffmpeg -i %srcfile% -movflags faststart -q:a 0 -q:v 0 -pix_fmt yuv420p -sws_flags gauss -s 4096x4096 %dstfile%

the output

ps: yes, playing @ home, theme 2001 - space odyssey. can see 1k youtube version here: 2001 - fulldome space odyssey , yes, in planetarium sound system, absolutely epic.

i think you're running limitation of of x264's codec complexity levels.

brief description of levels http://en.wikipedia.org/wiki/h.264/mpeg-4_avc

as term used in standard, "level" specified set of constraints indicate degree of required decoder performance profile. example, level of support within profile specifies maximum picture resolution, frame rate, , bit rate decoder may use. decoder conforms given level must able decode bitstreams encoded level , lower levels.

the max resolution highest level (5.2) 4,096×2,304.

i using hevc designed these larger format 4k / ultra-hd resolutions.

http://en.wikipedia.org/wiki/hevc

max resolution hevc 8,192x4,320

i want use tooltipster plugin click element in body show tooltip , want have close button inside tooltip close it. however use jquery click() function handle won't fired. tried solution in post. worked when tooltip triggered hover event. tooltipster plugin not firing jquery function when link in in tooltip clicked the original solution using hover in jsfiddle trigger: 'hover', instead using click show tooltip trigger: 'click', http://jsfiddle.net/bcqyl/7/ it won't fire click event in jquery block. can captured normal javascript function only. checked should code in tooltipster plugin locked , captured "click()" event inside tips when in click trigger mode. i tried other event onchange event of radio button fired when using code in original solution @evan right. tooltip doesn't exist in dom , can't bind/delegate action (even if go way $(document) after domready). if you're after close button inside of too...
