[QUOTE="seven5, post: 146410, member: 49857"] I can't seem to get an iPod transcode to work at all. Here is the FFMPEG command that is being generated by the transcoder plugin: -i "<INPUT FILE>" -vcodec mpeg4 -vtag MP43 -s 640x480 -b 1024k -r 25 -async 1 -mbd 2 -qmin 2 -bug autodetect -acodec aac -ab 128 "<OUTPUT FILE>" ANd here is my source video, and the outputed video, respectfully [ATTACH]6482[/ATTACH] [ATTACH]6483[/ATTACH] its some how wrecking the audio file. it should just be 2 channel AAC. Also, its putting the new file into an AVI container, and it needs to be in an MP4 container. I've also tried this with xvid. I've done a ton of transcoding to the iPod with ffmpeg over the last couple of years, and this is the command line i use, for reference: ffmpeg -i '30.Rock.S01E12.HDTV.XviD-NoTV.avi' -vcodec xvid -b 1200 -qmin 3 -qmax 5 -bufsize 4096 -g 300 -acodec aac -ab 128 -s 624x352 -title 'Episode 12' -author '30 Rock' 30_rock_01_12.mp4 using an MP4 extension, makes ffmpeg put it into the right container, not an avi container. aspect isn't really even used, but size is. When i automate this, i use ffmpeg to get the video size, and then mathmatically formulate the correct video size for conversion, if i'm scaling it down. This way, 4:3 videos look fine, and so do odd aspected videos like movies, etc. Not everything is 16:9 and 4:3. The last bit I thought i'd add is [URL="http://atomicparsley.sourceforge.net/"]atomicparsley[/URL]. It edits the 'atoms' in an MP4 file. This is essential, and almost only useful, for iTunes. By running this command, i can set the season #, episode # and show name to the meta data. This way itunes picks it up as a tv show and shows it under my shows, and not just my movies. Its very very nice. atomicparsley '30_rock_01_12.mp4' --TVShowName '30 Rock' --TVSeasonNum '1' --TVEpisodeNum '12' --genre 'TV Shows' --stik 'TV Show' --overWrite I think this would be easy to integrate, since you are contextually choosing video types anyways (My videos, My Tv ), so you could run this just on transcodes that happened within the My Tv context. Or, if you get Mp-TvSeries support, in there too. Please, if you have any questions, let me know. I'd love to help/see the transcode plugin get great support for iPod transcodes. [/QUOTE]
