Here is the current command I'm using (does not work unless i remove -loop argument) ffmpeg -i short.mp4 -loop 1 -i xfly.pgm -loop 1 -i yfly.pgm -filter_complex remap -c:v libx264 -c:a copy out.mp4Īfter additional research, the -loop option should come before file input, not the image map input. I believe I need to use the -loop argument before my filter files in order to process the image data as a frame, however when I attempt this, I get an error: failed to reallocate parser bufferĬan anyone provide guidance on how to properly use FFMPEG remap on a video file? Is there a fisheye or dual fisheye to equirectangular filter for ffmpeg? I am successful with processing still images, but when attempting to output video, I only get black frames. In doing so, I am using the projection script as documented in the Remap page of the FFMPEG docs to generate the map files for my camera. Conclusions: Our results demonstrate that pregnancy upregulates differentially the expression of PLIN isoforms along with PGC-1α, suggesting that together they might be involved in the regulation of the lipid metabolic shift induced by pregnancy.I'm attempting to use FFMPEG Remap filter to convert a circular fisheye video to an equirectangular shape. Moreover, TAG and total cholesterol increased during pregnancy and returned to basal levels after pregnancy.
PGC-1α mRNA and protein expression increased during pregnancy and the postpartum period. Results: The expression of mRNAs for PLIN1, 2, and 5 increased during pregnancy and the postpartum period. TAG and total cholesterol content were evaluated using commercial colorimetric methods.
The mRNA and protein levels were evaluated using quantitative RT-PCR and Western blotting, respectively. Materials and Methods: Female Sprague-Dawley rats were divided into three groups: non-pregnant, late pregnancy, and postpartum. The aim of this study was to quantify the mRNA expression of PLIN isoforms and PGC-1α along with total triacylglycerol (TAG) and cholesterol levels during late pregnancy and the postpartum period in the rat left ventricle. However, the changes in PLIN isoforms’ expression in response to pregnancy-induced cardiac hypertrophy are not thoroughly studied. Background and Objectives: Perilipins 1–5 (PLIN) are lipid droplet-associated proteins that participate in regulating lipid storage and metabolism, and the PLIN5 isoform is known to form a nuclear complex with peroxisome proliferator-activated receptor-gamma coactivator 1-alpha (PGC-1α) to regulate lipid metabolism gene expression.
