Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

Update UploadHandler.php
22 juillet 2017, par jbostoenUpdate UploadHandler.php
imagick_create_scaled_image :
jpeg_quality was ignored if it was the only parameter set (similar to previous patch for ’strip’ exif information)
instead of a negative condition, turned it around : if dimensions are within limits and no changes required (strip exif, jpeg quality, orientation), then return original image
added comment warning about the implications of setting options on the ’original’ image ( version ’’ ). All other versions inherit those settings.

FFmpeg : how to make video out slides and audio
7 juillet 2014, par Muhammad UmerSo i have several images some png and some jpgs. And i have mp3 audio. I want to make a video file don’t care what format.
So i want either :
A video made up of xyz size meaning images are centered and cropped if they go beyond dimensions coupled with audio in mp3 format..
I have tried copying and pasting things and even modifying them after reading documents but in the end i got a blank video with audio and huge file that took forever to complete.
I have windows 7.

libavcodec/vp8dec : fix the multi-thread HWAccel decode error
11 juin 2019, par Shaofei Wanglibavcodec/vp8dec : fix the multi-thread HWAccel decode error
Fix the issue : https://github.com/intel/media-driver/issues/317
the root cause is update_dimensions will be called multple times
when decoder thread number is not only 1, but update_dimensions
call get_pixel_format in each decode thread will trigger the
hwaccel_uninit/hwaccel_init more than once. But only one hwaccel
should be shared with all decode threads.
in current context,
there are 3 situations in the update_dimensions() :
1. First time calling. No matter single thread or multithread,
get_pixel_format() should be called after dimensions were
set ;
2. Dimention changed at the runtime. Dimention need to be
updated when macroblocks_base is already allocated,
get_pixel_format() should be called to recreate new frames
according to updated dimension ;
3. Multithread first time calling. After decoder init, the
other threads will call update_dimensions() at first time
to allocate macroblocks_base and set dimensions.
But get_pixel_format() is shouldn't be called due to low
level frames and context are already created.In this fix, we only call update_dimensions as need.
