Hi jriver-team,
I tried converting a recorded TV-show from .ts to H264-ts to save space on my HDD. It works nicely except the 5.1 audio-track is converted to 2.0.
Is multichannel audio not supported by H264-codec? If not, which codec should I use then?
EDIT:
Rather, the original file has 3 audio tracks, and it seems only track 1 is stored in the converted file:
1: 2.0
2: 2.0 (national language translation)
3: 5.1 AC3
Best regards,
Mikkel

I don't think this has to do with h.264 (or x.264) which is only the video codec, but rather with the container (mp4, mkv) audio and video streams are stored in. Not all containers support all audio or video formats.
I don't know enough about MC's video conversion capabilities to tell you what is going wrong in your case, sorry.

Can you try to play the original and select the 5.1 track first. Then try the conversion. Does it then work as you'd like.

No, not really. The 5.1 track is in fact selected automatically (no idea why) but it doesn't make the converter pick it.
I have extremely little knowledge of containers and codecs but to me it seems that either the converter:
a) Selects only track 1 (2.0 audio); or
b) Converts 5.1 to 2.0
Maybe all we lack is a way of selecting the audio track for multi-track recordings?
Best regards,
Mikkel

I believe all the existing video converter profiles convert to stereo.
Someday we may expand this. The matrix of encoding possibilities for video is somewhat overwhelming, so we have to balance flexibility with something that's understandable.

I kind of have a foggy image in my head of a conversion dialog which would be more flexible on the profiles, or allow only transcoding video and keeping audio as-is. But it'll be quite a while until something like this would see the light of day.
Its certainly an area with great potential for improvements.

I've been in and out of video conversion. For he last few years. As a side project. And I will say this. I would love nothing more than for MC to handle all my audio video needs.
However they will never get to do anything else. It's a never ending cycle of change. Where there is always something old something new and something blue.
If I had a cmd line option for all conversions I would be a happy camper!

+1 on this. The current profiles all downmix to 2.0 which is great for most portable and basic DLNA requirements but we already have the flexibility with Audio files for conversion or DLNA streaming to select 5.1 or 2.0 but just not with Video.
The option I personally like would the ability to create custom profiles that you could then just use for both file conversion and DLNA steaming. You could even have a simple GUI to "generate" these profiles that could then be saved then exposed in MC as one of the transcoding options. It would hide the complexity in a one time creation process and then it would be a simple to select like any of the existing ones. Another benefit was the user community could create, test and share such profiles with other users here on Interact - a bit like other plugins and skins.
Edit: This idea is pinched from how Handbrake works, you have some std presets but the ability to create your own (I even suggested that you could use the same format for these custom profiles so you could use the ones Handbrake does).

Would you like VideoReDo to open JRiver JTV files directly?
Would you like to trim and edit your TV recordings made in JTV and TS format?
If so, get over to this thread: http://yabb.jriver.com/interact/index.php?topic=92571.0 and do something about it!
