#406 closed defect (fixed) mythtranscode --mpeg2: sample rate not set - Error writing output header Reported by: laga@… Owned by: anonymous Priority: minor Milestone: unknown Component: mythtv av_dump_format Version: head Severity: medium Keywords: Cc: Ticket locked: yes Description Hello
Ffmpeg Muxing
all! I'm trying to use the new mpeg2 transcoding which was introduced to MythTV in ticket #158.
Avcodec_encode_video2
However, I'm experiencing a problem with mythtranscode just quitting without actually doing anything. Here comes the log: mythtv@styx:/mnt/foo/video$ mythtranscode --mpeg2 --infile 1070_20050925201000_20050925221000.nuv --honorcutlist 2005-10-01 23:14:14.891 Using runtime https://www.ffmpeg.org/doxygen/2.2/transcode_aac_8c-example.html prefix = /usr 2005-10-01 23:14:14.954 New DB connection, total: 1 2005-10-01 23:14:14.985 New DB connection, total: 2 2005-10-01 23:14:15.005 Begining MPEG2 to MPEG2 transcode of Donnie Darko (Donnie Darko) - ... cutlist will be honored.

I'm running Debian Sarge and MythTV is built from yesterday's SVN. I recorded this show off my DBox (thanks to levon), so I think it's DVB style. Mythtranscode --mpeg2 seems to work ok so far on other recordings, but this one also shows an odd behaviour in mythfrontend: I can select two audio tracks, one being the regular German audio track ("unknown mp2 2ch"), the other one is called "unknown mp3 2ch". When I switch to the second track, I don't get any sound. In conclusion, I think that this is not usual for a recording, but it still would be nice to transco

entire manual describing the process of data import/export. And, despite all of that text, most of the packages described are (to varying degrees) out-of-date. Faster, simpler, packages with fewer dependencies have been created for many of the file types described in that document. rio aims to unify data I/O (importing and exporting) into two simple functions: import and export so that beginners (and experienced R users) never have to think twice (or even once) about the best way to read and write R data. The core advantage of rio is that it makes assumptions that the user is probably willing to make. Specifically, rio uses the file extension of a file name to determine what kind of file it is. This is the same logic used by Windows OS, for example, in determining what application is associated with a given file type. By taking away the need to manually match a file type (which a beginner may not recognize) to a particular import or export function, rio allows almost all common data formats to be read with the same function. By making import and export easy, it's an obvious next step to also use R as a simple data conversion utility. Transferring data files between various proprietary formats is always a pain and often expensive. The convert function therefore combines import and export to easily convert between file formats (thus providing a FOSS replacement for programs like Stat/Transfer or Sledgehammer). Supported file formats rio supports a variety of different file formats for import and export.
