FFmpeg : why we need to create temp files during conversion
29 mars 2019, par Awais fiazI have been studying about ffmpeg, its properties and its usage. I have started using a pre-made PHP based script which creates temp files during conversion. I am trying to figure out what it actually does in this given command. Why is this command creating temp files during conversion and what is the purpose of it ?
/usr/bin/ffmpeg -y -i /var/www/html/conversion_server/files/conversion_queue/15270581986ece98.mp4 -f mp4 -vcodec libx264 -preset superfast -r 23.97598565277 -maxrate 320000 -g 60 -crf 29 -profile:v baseline -s 426x240 -aspect 1.77 -acodec libfdk_aac -ab 320k -ar 44100 /var/www/html/conversion_server/files/videos/2018/05/23/15270581986ece98/15270581986ece98-240.mp4 2> /var/www/html/conversion_server/files/temp/1527058199834e4.tmpAny help regarding this would be really appreciated.

configure : error out on unsupported MSVC versions
15 mai 2018, par Rostislav Pehlivanovconfigure : error out on unsupported MSVC versions
The FATE tests for MSVC versions older than 2013 are untested in FATE
and apparently are no longer supported.This commit makes the configure process error out in case an older version
is used, and suggests to use a supported version of MSVC to compile.This also changes the documentation to reflect this.
As discussed on IRC :
2018-05-12 19:45:16 jamrial then again, most of those were for old msvc, and i think we're not supporting versions older than 2013 (first one c99 compliant) anymore
2018-05-12 19:45:43 +JEEB yea, I think 2013 update 2 is needed22:53 <@atomnuker> nevcairiel : which commit broke/unsupported support for msvc 2013 ?
23:23 <@atomnuker> okay, it was JEEB
23:25 <+JEEB> which was for 2012 and older
23:25 <+JEEB> and IIRC we no longer test those in FATE so that was my assumption
23:26 <+JEEB> 2013 is when MS got trolled enough to actually update their C part
23:26 <+JEEB> aand actually advertised FFmpeg support
23:26 <+JEEB> (although it was semi-failing until VS2013 update 1 or 2)Signed-off-by : Rostislav Pehlivanov <atomnuker@gmail.com>

ffmpeg : Cannot open libx265 encoder. Error initializing output stream 0:0 — Error while opening encoder for output stream #0:0
16 mai 2018, par bngeSorry for my bad English. I am trying to use ffmpeg to convert some image to heic format. Most of them were succeeded, but some large jpeg (seems only jpeg, png will be okay) files not.
How can I improve my command to compatible all my images, so I can convert them automatically ?
