By adding extra codecs after the official distro installation:
ffmpeg -v quiet -codecs | grep aac DEAIL. aac AAC (Advanced Audio Coding) (decoders: aac aac_fixed libfdk_aac ) (encoders: aac libfdk_aac ) D.AIL. aac_latm AAC LATM (Advanced Audio Coding LATM syntax)
Good to know! So if ffmpeg present in CinGG supports AAC, just make presets to be able to use them.
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: https://opensuse-guide.org/codecs.php
Where did you see the latter preset? (I think it is DV SD on Blu-ray).
Sorry for my ignorance on Blu Ray and DV/HDV. The presets I found are in the attached bluray-DV.jpg image. Instead, the presets of Andrew that you have indicated, are perhaps those in the image bluray-HDV.jpg?
Yes, FHD, HDV and SD DV are identified here by their standard pixel resolution, frame rate and interlaced or progressive video. ref: https://en.wikipedia.org/wiki/Blu-ray#Video https://en.wikipedia.org/wiki/Pixel_aspect_ratio#Pixel_aspec t_ratios_of_common_video_formats
I can't find any HDV or similar.
Compare also with Settings>Format window's Presets up to the left (where HDV and DV are listed for the Import video)
Do you only use "Create BD" or "Create DVD" to make a BD/DVD, and not
the presets found in the rendering window? [FFMPEG --> mt2s --> "wrench" --> bluray_dv_pal(ntsc).mt2s] What is the purpose of the latter?
I think format presets used by bluray/dvd gui internally..
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).
I could not find manual documentation for the presets. So possibly Andrew with better knowledge may step in here and explain better?
https://cinelerra-gg.org/download/CinelerraGG_Manual/How_Create_FFmpeg_Optio... basically I just started with muxer codec pair in new options file, and then played with parameters..
I will just add that It possible to render various .m2ts files, test mediainfo and playback using a media player like VLC.
Note: vlc or other software player may tolerate streams hw player will choke on.. As known a Blu-ray player device need a standard Blu-ray disc directory
structure (bdwrite) for playback, i.e
tree -h bd_20161216-153642
bd_20161216-153642 ├── [183M] bd.m2ts ├── [ 394] bd.sh ├── [191M] bd.udfs ├── [5.3K] bd.xml └── [4.0K] udfs
1 directory, 4 files
While DVD use MPEG-2, I cannot see MPEG-2 with high bitrate for SD DV (or HDV) on Blu-ray is possible?
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) ..
