Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...)

avcodec/aacdec_common : Combine huffman tabs

Encode piped images as they arrive
1er août 2024, par Aviad P.I'm encoding a video by piping images into
ffmpeg
using the-i pipe:
input.
However the images arrive sporadically, but are encoded as if they are sequential frames.

I have tried using
-use_wallclock_as_timestamps 1
in the input block, but it has no effect.

This is the command I'm using :


ffmpeg -use_wallclock_as_timestamps 1 -i pipe: -vf fps=50 -c:v libx264 -map 0 -f segment -segment_list playlist.m3u8 -segment_list_flags +live -segment_time 10 -segment_wrap 5 seg%03d.mkv


Input block parameters I've tried to no avail :


- 

-re
-framerate 1
-framerate 1/1000
-framerate 50










So to reiterate the problem : A video is being produced, but each piped image is set as an individual frame, despite having arrived and encoded at an entirely different time that its predecessor.

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
