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 (...) -

How to log unconverted files in FFMPEG due to error ?
10 juillet 2017, par eugenemonI am converting 30,000 video files (each with different number of data/video/audio/subtitle streams) using a single batch file. I do not require data/subtitle streams. This is the code I am using for the batch file :
for %%i in (*.dat *.mpg *.mpeg) do ffmpeg -hide_banner -v info -n -i %%i -map 0 -dn -sn -c:v libx264 -crf 20 -c:a aac -b:a 192k "%%~ni.mp4" >> log.txt 2>&1
pauseThe resulting log file that I get is 1.67gb in file size and is extremely difficult for me to go through to find the errors of files that weren’t converted.
An example of a successfully converted file would look like this in the log file :
Input #0, mpeg, from '571317.mpg':

Automatic encoder selection failed for output stream #0:2. Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
Error selecting an encoder for stream 0:2How exactly can I output a log file that simply state the files that weren’t converted and the error that entails. Example :
000002.mpg - Not converted
Automatic encoder selection failed for output stream #0:2. Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
Error selecting an encoder for stream 0:2
000123.mpg - Not converted
Automatic encoder selection failed for output stream #0:2. Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
Error selecting an encoder for stream 0:2This way, I won’t have to toy with a huge log file. Thanks !
