Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
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 ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

tests/checkasm/svq1enc : Use proper range for input
6 mai 2024, par Andreas Rheinhardttests/checkasm/svq1enc : Use proper range for input
ssd_int8_vs_int16 is only called from encode_block()
in svq1enc.c ; it calls it in stages : At stage 0,
the int16_t array contains the difference of two
uint16_t. At each of the following stages, the
int16_t array is filled by subtracting an int8_t from
the current stage's int16_t array. The maximum stage
is five, so the int16_t are in the range
(-255 - 5 * 127)..(255 + 5 * 128).This commit modifies the checkasm test to only use
values from this range, fixing (undefined) integer overflow
in the test.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

FFmpeg Flags for generating fixed amount of images related to video length
27 octobre 2015, par SutekhI am using this command :
ffmpeg -i file.mp4 -vf fps=1/60 -s 274x175 thumb%d.png
to extract 1 frame from video for every minute of it.
What i want to learn how to do is :
Extract a total of 10 images from video regardless of its length that are relative to distance of video.Example :
1.If video length is 15 minutes (900 seconds) it will extract one image from every 90 seconds of video.
2.If video length is 22 minutes (1320 seconds) it will extract one image from every 132 seconds of video.And one more thing , is it possible to use ffmpeg to set output quality of those images or limit maximum size(as in file size , not dimensions) for each image that is going to get outputted ?
