The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...) -
Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

tile option in FFMPEG command result to black screenshot
4 mars 2020, par sammaxI am managing to create a screenshot using ffmpeg engine and it works fine when I am try to output one individual image
ffmpeg -ss 01:05 -i input.mp4 -an -dn -sn -r 1 -vframes 1 -y -qscale 3 -vf "scale=width:high"
But when I try to create a multi-image (Thumbnail grid sheets) using
tile
option the output screenshot is empty blackffmpeg -ss 01:05 -i input.mp4 -an -dn -sn -r 1 -vframes 1 -y -qscale 3 -vf "select=not(mod(n\,3000)),scale=320:240,tile=4x3"
and here is what I want to achieve image

pngdec : add ability to check chunk CRC
7 mars 2019, par Lynnepngdec : add ability to check chunk CRC
By default now, if AV_EF_CRCCHECK or AV_EF_IGNORE_ERR are enabled the decoder
will skip the chunk and carry on with the next one. This should make the
decoder able to decode more corrupt files because the functions which decode
individual chunks will very likely error out if fed invalid data and stop the
decoding of the entire image. -
Revision 8350e7fe38 : Make intra prediction pointers RTCD-based. This probably has a mildly negative
9 juillet 2013, par Ronald S. BultjeChanged Paths :
Modify /vp9/common/vp9_reconintra.c
Modify /vp9/common/vp9_rtcd_defs.sh
Modify /vp9/common/x86/vp9_recon_sse2.asm
Delete /vp9/common/x86/vp9_recon_wrapper_sse2.c
Modify /vp9/encoder/vp9_mbgraph.c
Modify /vp9/vp9_common.mk
Make intra prediction pointers RTCD-based.This probably has a mildly negative impact on performance, but will
(in future commits - or possibly merged with this one) allow SIMD
implementations of individual intra prediction functions. We may
perhaps want to consider having separate functions per txfm-size
also (i.e. 4x4, 8x8, 16x16 and 32x32 intra prediction functions for
each intra prediction mode), but I haven't played much with that
yet.Change-Id : Ie739985eee0a3fcbb7aed29ee6910fdb653ea269
