14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.

subprocess call of ffmpeg returns negative value
11 juin 2019, par Zak44Here is the original command line call that works at shell :
ffmpeg -i /Users/abc/Desktop/Test/Full_Mov.mov -vf "drawtext=fontfile=/System/Library/Fonts/Keyboard.ttf: text='SCENE BLAH BLAH - %{frame_num}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: fontsize=20: box=1: boxcolor=black: boxborderw=5","format=yuv420p" -f segment -segment_frames 123 -reset_timestamps 1 -c:a copy -map 0 "/Users/abc/Desktop/Test/%03d_test40.mov"
Getting a negative value when trying to run ffmpeg via subprocess, causing it to fail and not process. I’ve even tried dumbing down the call to just run ffmpeg by itself with no arguments, and it still returns a negative value.

configure : Improve the check for the rsync —contimeout option
24 janvier, par Martin Storsjöconfigure : Improve the check for the rsync —contimeout option
Traditionally, macOS has shipped an old version of rsync that lacked
support for this option, hence this check (added in
a8b3f0c5cf548f654e30c981988bb71981a3f8d3).However, in macOS 15.x, Apple have switched to providing rsync as a
different tool, openrsync. The version of openrsync in at least
macOS 15.2 does include "[—contimeout]" (note the lack of "=" after
the option), in the output of "rsync —help", but when used, the tool
errors out with "rsync : —contimeout=60 : unknown option". So apparently
the tool erroenously lists the option as supported, while it really
isn't.The original rsync tool (with a new enough version) prints
"—contimeout=SECONDS" in the output of "rsync —help".It is unclear which version of openrsync Apple are shipping ; the latest
upstream openrsync from OpenBSD does support the option and includes
"[—contimeout=seconds]" in the output of "—help", and older versions
don't seem to include the option as listed at all.Therefore, check for "—conntimeout=" with the "=", this should
properly detect both new enough rsync and openrsync.This fixes running "fate-rsync" on macOS 15.x.
