By adding extra codecs after the official distro installation:<br>
ffmpeg -v quiet -codecs | grep aac<br>
DEAIL. aac AAC (Advanced Audio Coding) (decoders: aac<br>
aac_fixed libfdk_aac ) (encoders: aac libfdk_aac )<br>
D.AIL. aac_latm AAC LATM (Advanced Audio Coding LATM syntax)<br>

Good to know! So if ffmpeg present in CinGG supports AAC, just make<br>
presets to be able to use them.<br>
</blockquote>
<br>
Yes, I think so. The output above was from my openSUSE system's ffmpeg after adding multimedia codecs and enabled applications following the unofficial guide:<br>

Where did you see the latter preset? (I think it is DV SD on Blu-ray).<br>
</blockquote>
Sorry for my ignorance on Blu Ray and DV/HDV. The presets I found are<br>
in the attached bluray-DV.jpg image.<br>
Instead, the presets of Andrew that you have indicated, are perhaps<br>
those in the image bluray-HDV.jpg?<br>
</blockquote>
<br>
Yes, FHD, HDV and SD DV are identified here by their standard pixel resolution, frame rate and interlaced or progressive video.<br>

I can't find any HDV or similar.<br>

<br>
Compare also with Settings>Format window's Presets up to the left (where HDV and DV are listed for the Import video)<br>

Do you only use "Create BD" or "Create DVD" to make a BD/DVD, and not<br>
the presets found in the rendering window? [FFMPEG --> mt2s --><br>
"wrench" --> bluray_dv_pal(ntsc).mt2s]<br>
What is the purpose of the latter?<br>

I think I have tested both methods, mostly in 2016/201, and just a few later. (Beside I have digitized several analog S-video to DV video files and recorded them to BD-R data discs as backup. I have at least 20-30 of each Hi8 and HDV tapes left).<br>
<br>
I could not find manual documentation for the presets. So possibly Andrew with better knowledge may step in here and explain better?</blockquote><div><br></div><div><a href="https://cinelerra-gg.org/download/CinelerraGG_Manual/How_Create_FFmpeg_Options_F.html">https://cinelerra-gg.org/download/CinelerraGG_Manual/How_Create_FFmpeg_Options_F.html</a></div><div><br></div><div>basically I just started with </div><div><br></div><div>muxer codec</div><div><br></div><div>pair in new options file, and then played with parameters.. </div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I will just add that It possible to render various .m2ts files, test mediainfo and playback using a media player like VLC.</blockquote><div><br></div><div><br></div><div>Note: vlc or other software player may tolerate streams hw player will choke on.. </div><div><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
As known a Blu-ray player device need a standard Blu-ray disc directory structure (bdwrite) for playback, i.e<br>
<br>
tree -h bd_20161216-153642<br>
<br>
bd_20161216-153642<br>
├── [183M] bd.m2ts<br>
├── [ 394] bd.sh<br>

├── [5.3K] bd.xml<br>
└── [4.0K] udfs<br>

While DVD use MPEG-2, I cannot see MPEG-2 with high bitrate for SD DV (or HDV) on Blu-ray is possible?</blockquote><div><br></div><div>well, you can try to create mpeg2 m2ts profile and temporarily replace usual h264-based ones.. if this experiment resulted in working BD disk - we probably can add checkbox or menu selecting specific codec. Just bitrate for mpeg2 must be much higher for same quality at given resolution (saw 40 mbit/s fullhd file) , and blu-ray has hard limit on bitrates it can handle (from memory: around 25 mbit/s) .. </div><div><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
