Cambridge audio 752BD with newer MKV files

Hi All

Having troubles with the 752 not playing newer formats. I think the issue is anything greater than level 4.1 and of course H265 files.
So, I want to be able to transcode these files to a supported level for the player. Will this custom mod work?

(changed the level to TRUE)

RendererName = Azur BD
RendererIcon = cambridgeaudioazur752bd.png
UserAgentSearch = AZUR BD PLAYER

HalveBitrate = true
TranscodeVideo = MPEGTS-H264-AC3
DefaultVBVBufSize = true
H264Level41Limited = true
MuxLPCMToMpeg = false
TranscodeExtensions = vob
StreamExtensions = aac,ape,asf,avc,avi,dat,dff,divx,dsd,flv,flac,m2t,m2ts,mts,m4a,m4v,mp1,mp2,mp3,mp4,mpeg,mpg,mka,mkv,mov,pcm,QT,ts,vcd,vob,wav,wma,wmv,xvid
MediaInfo = true

Hi,

Sadly you cannot do much more than what you already found out, only H.264 level will be restricted to 4.1 level and all the other video codecs like HEVC will not.
Using FFmpeg optional custom parameters "-vpre" could be used as a workaroud but i'm afraid that most users will find that overskilled and annoying.

@floatingkiwi the change you provided should work for the level but we will need to do more to make sure that H.265 doesn't stream. Please try this and let me know how that works:

Code: Select all

#----------------------------------------------------------------------------
# Profile for Cambridge Audio Azur BD players.
# See DefaultRenderer.conf for descriptions of all the available options.
#

RendererName = Azur BD
RendererIcon = cambridgeaudioazur752bd.png
UserAgentSearch = AZUR BD PLAYER

TranscodeVideo = MPEGTS-H264-AC3
DefaultVBVBufSize = true
MuxLPCMToMpeg = false
MediaInfo = true

# Supported video formats:
Supported = f:avi
Supported = f:divx
Supported = f:flv
Supported = f:mkv      v:divx|h264|mp4|xvid
Supported = f:mov
Supported = f:mp4      v:divx|h264|mp4|xvid
Supported = f:mpegps   v:h264|mpeg1|mpeg2|mp4
Supported = f:mpegts   v:h264|mpeg1|mpeg2|mp4   m:video/vnd.dlna.mpeg-tts
Supported = f:vob
Supported = f:wmv

# Supported audio formats:
Supported = f:adts
Supported = f:aiff
Supported = f:ape
Supported = f:dff|sdf
Supported = f:flac
Supported = f:m4a
Supported = f:mka
Supported = f:mp3|mp2|mpa
Supported = f:wav
Supported = f:wma

I have completely replaced the mod file with your content. Correct?

Nope, all I get when playing a H.265 file (1080p) is a slideshow with 2 pictures, a white moon and a moon with the union jack. Thats all. No video file!!

Interesting, how about:

Code: Select all

RendererName = Azur BD
RendererIcon = cambridgeaudioazur752bd.png

Supported = f:mpegps   v:h264|mpeg1|mpeg2|mp4
Supported = f:mpegts   v:h264|mpeg1|mpeg2|mp4
Supported = f:vob
Supported = f:wmv

# Supported audio formats:

Please try varying the TranscodeVideo line. The possible options are:

Code: Select all

TranscodeVideo = MPEGPS-MPEG2-AC3
TranscodeVideo = MPEGTS-MPEG2-AC3
TranscodeVideo = MPEGTS-H264-AC3
TranscodeVideo = MPEGTS-H264-AAC
TranscodeVideo = WMV
I suggest starting with MPEGTS-H264-AAC
