Native format for Sony Bravia TV Streaming

[jwgill]

Hi

I am trying to stream bluray rips to a Sony Bravia KDL-32EX43B from Mezzmo. If I select one of the m2ts files from the raw bluray rip it "plays" on the TV, but lots of stuttering and louds clicks and pops on the audio; if I fast forward a picture is displayed. I am guessing this is caused by Mezzmo transcoding and not being able to keep up due to a lack of horse power from my WHS Server hardware.

I would like to know what audio, video and container formats the Bravia will take native with no transcoding required from Mezzmo. Preferably something that will retain the closest picture quality to the bluray original; the audio can degrade down to simple stereo as I don't currently have a surround amp, just an old hifi stereo amplifier. Any guidance on transcoding software to achieve this would also be gratefully received. I have tried AVS Video Converter into MPEG2 HD, which works and the file plays, but the picture quality is comparable to standard DVD not Bluray. I am happy to pay for a commercial package for a simple convenient conversion with good lipsync etc.

My set up is WHS on a foxconn motherboard with a E3300 2.5GHz, 2Gb ram with gigabit ethernet into a Billion 7600N router and then 200mbps powerline adapter to the Sony Bravia TV. Mezzmo has the Sony Bravia KDL profile and the 200mbp powerline option set. I hope this isn't too much of a naive request or repeating a question asked many times before.

Thanks in advance.

Hi Jonathan,

You'd want to convert your rips to AVCHD which is h264 video with AC3 audio (5.1 is fine) and enclosed in an MPEG-TS stream. This is actually what Mezzmo will transcode to. If you don't mind doing it manually, then you can check the logs from Mezzmo to see how we do it and then just use FFmpeg to convert your rips - this will give you a free solution.

Hi Dennis

I created a h264 and ac3 file in a ts container with a commercial package (aunsoft video converter) with bitrates, sampling rates etc set to be as per the original. When I played this it was transcoded by Mezzmo. So I decided to try and recreate the transcoded file as per your suggestion in the hope that this would then be streamed direct by mezzmo.

I cleared my transcode cash and played the original ts file (raw VC-1 video and AC3 from bluray rip muxed with TSMuxer). This created a new transcode and from the transcode log was able to create a new version in ffmpeg as per your suggestion. I then cleared the transcode cache again and turn off transcoding and tried to play the ffmpeg created file. It didn't even appear in the list of files to play! I have turned transcoding back on and the same again, this new manually transcoded file is not listed as one that can be played. This file plays ok in TMT5 so not sure what is going on. The ffmpeg detail is:

ffmpeg.exe -i "tsremux.TS" -y -vcodec copy -level 41 -vf "scale=1920:1080" -acodec copy -sn -f mpegts -threads 4 -pix_fmt yuv420p -copyinkf -coder 1 -flags +loop -fflags +genpts -cmp +chroma -me_method hex -subq 7 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 1 -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -directpred 1 -flags2 +fastpskip+bpyramid+mixed_refs-dct8x8+wpred+aud+ivlc+mbtree -partitions -parti8x8-parti4x4-partp8x8-partp4x4-partb8x8 -crf 22 -bf 1 -refs 2 -bidir_refine 1 -deblockalpha 0 -deblockbeta 0 -vbsf h264_mp4toannexb -deinterlace "out.ts"

When I go to the mezzmo transcode directory and try and play the on-the-fly transcode file (extension .mzt) this file is not available for playing on the tv either. Any ideas on what is going on? As I said before I am trying to create a transcoded file that the tv can play straight from a direct stream from mezzmo, no further processing from mezzmo required.

Thanks in advance

Hi Jonathan,

The .mzt extension is excluded from files that Mezzmo picks up. Change the extension to .m2ts (for example) and then it should be picked up by Mezzmo.

Did you find a usable answer - what is the native format which Bravia will play with no trans-coding? Obviously it is NOT m2ts as many tests have confirmed that. Any ideas? I would love to be able to backup BDs onto NAS and play them naively with no trans-coding?

Mezzmo transcodes incompatible files for Sony Bravia TVs to:

Container: mpegts
Video channel: h264 (Main), level 41, max 6M video bitrate
Audio channel: ac3, max 448000 audio bitrate

If you do the same with your Blu-ray rips, then they will be played natively by your Sony Bravia TV when streamed via Mezzmo. Try this on a Blu-ray rip and see how you go. If it does not work, then let me know your Sony Bravia TV model and the device profile you are using for your TV in Mezzmo (go to the Media Devices dialog to see this).

Well, i have tried encoding like that and they play but only if I select the bravia mp4 profile, not in the normal bravia one (where i only get a black screen).

Is this normal?
