Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?

Duplicated frames when mering multiple videos with xfade filter (ffmpeg)
25 février 2021, par tjkI'm stuck with merging multiple videos with audio. This used to work on most videos I merged before but with some videos, I get the "More than 1000 frames duplicated" warning, and the output video is broken (some videos won't play, just static picture and the sound is misaligned).


All videos are in the same format afaik. The only difference I see is that some are "yuvj420p(pc)" and most are "yuv420p". But I tried merging without those with "yuvj420p(pc)" and it didn't help.


Already tried adding "-vsync vfr", didn't help too.
Interestingly — if I remove the second or the last input video, no warning is given and it all works.


The command I use :

I am using ffmpeg java library to convert captured screenshots to video. Video output is blurry
2 octobre 2020, par dark princeI am using ffmpeg java library to convert captured screenshots to video. Video which is generated as output is blurry.


I am using bit rate as 9000, frames per sec as 25 and video size as that of desktop screen size.


Any suggestions on how to solve this issue.


P.S. I cannot use ffmpeg.exe and command line due to certain restrictions and hence I am opting for ffmpeg java library.


Any suggestions on the issue or suggestions on any better approach will be helpful.

Fast computation path for forward transform and quantizationThis commit enables a fast path computational flow for forward
transformation. It checks the sse and variance of prediction
residuals and decides if the quantized coefficients are all
zero, dc only, or more. It then selects the corresponding coding
path in the forward transformation and quantization stage.It is currently enabled in rtc coding mode. Will do it for rd
coding mode next.In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps
goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up.
Overall coding performance for rtc set is changed by -0.18%.Change-Id : I0452da1786d59bc8bcbe0a35fdae9f623d1d44e1
