First, thanks for your time and insight. Plex DVR reads the ATSC stream from the TV tuner via Linux DVB and uses ffmpeg to assemble the mpegts file. > You cannot put ass into mpegts. Understood. I’m only using ass when transcoding to mkv. The closed captions so far have been preserved in the h264/mpegts transcode. > Your input file is NOT interlaced, it is telecined, use an inverse > telecine filter.

Looks like some of the recorded files are interlaced and some are progressive. I’m not sure if this is the broadcast or if Plex is doing it. Which ever it is I don’t have influence on it. > The following works and keeps the Closed Captions, it may not > work correctly with the inverse telecine filter though: > $ ffmpeg -i input -acodec copy -vcodec lib264 out.ts That command is producing the same results. However, I tried playing with QuickTime Player (provided with Mac OS X) and the speed is correct. So the fault appears to be with MPlayer OS X Extended. Sorry that I didn’t try multiple players before posting.

Sorry for the confusion, it’s a statement of something I don’t like :) Namely, the transcode plays faster than it should.

It was popular at the time but with the release of the iPhone I would have had to re-write it to keep it going and I didn’t have the time. .PBD is the required extension for PalmOS Binary Database. > I have never seen any portion of "The Six Million Dollar Man", it looks > interesting.

This is an input sample. If you’ll look at the video stream you’ll see it’s mpeg2video which is what I’ve stated is the input. The output I desire is h264. > And please remove -hide_banner from your command line when asking questions > here. My first command output includes the banner. I didn’t think it was necessary to include multiple copies of the banner but in the future I will remove -hide_banner from all commands. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
