It may be asking too much but do you feel it would be possible to auto prefer an AC3 track over alternate tracks like DTS (as long as they match the preferred language)?
Many video files that I create or have come across offer both types of audio tracks so as to support different devices. This seems it would save time not having to transcode. No worries if not, this is already better than it was. |
It is possible, if you are running my version of pyTivo it has the audio lang settings slightly tweaked so that it reads all the details from ffmpegs. I have;
audio_lang = en, 5.1, 6 channels, ac3
In my version of pytivo these settings are evaluated from left to right until there is only 1 match. So if there are two 6 channel audio tracks it will select the ac3 track.

lucasnz,
Just sat down to test out some of your recent code and I am having failures with your most recent update (GIT@bc751c69ba9a4ce5c0e580aaa3b5d66816ac7105). The file is an MKV with h264 and 2ch AC3@ 384kbs
This issue is fixed by reverting two builds to (GIT@f65a7e7d81d51eaf456e0387e7d7279c77650213), just before your 2ch AAC code.
The only override I have in my .conf is for lang = eng
Here is the output.

I see from the output that the audio track says "stereo". I was aware that ffmpeg did this for some files but all the ones I had said 2 channel so I couldn't test that. There's obviously something wrong with my regular expression that isn't matching ", stereo," hence it's returning NoneType.
I'll look at this when I get home. Will re-post once I've fixed it... |

ahh I should have seen that. I'm glad you have a keen eye. I appreciate the work you have done on this.
I would think that if there is an expression labeled 'stereo' that there would be a 'mono' as well. |

Lucasnz I am still running across issues where compatible audio is being transcoded during the remux. Not certain what the issue is. For example this morning I pushed an MKV video with compatible h264 video and 2ch aac audio and pyTivo decided to transcode that aac into ac3 for whatever reason.
The only pytivo.conf override I have is for 'eng' language audio and 640k max audio bitrate.

I am looking at other possible unnecessary audio transcoding as well and I will let you know if I find any thing. I think that it was transcoding compatible 640k ac3 to 640k ac3 on another video. I didn't happen to copy the debug output on that occasion but the remux was going very slow and the FFmpeg output led me to believe it was transcoding the audio. |

Hmmm - I note that it says transcoding to tivo model ***. Is that because you've stared it out, or has pytivo failed to detect what model your tivo is? If pytivo has failed to detect your tivo model that could explain why it's transcoding. That is it's transcoding to a "known" good format supported by most tivos.
I really need to see the debug output above this in order to understand why it is transcoding. In particular there should be a line that displays all the meta data. I'm looking to see what aCh is set to.

Sorry I thought I grabbed everything. I did star out the TiVo model. It is a premiere.
Also I have confirmed that if I set the max_audio_br to 640k the audio will still get transcoded down to 448k or even re-transcoded to 640k if I have the audio_br set to 640k. I will work on logs when I can.

Not sure what to do about this. It seems to be because ffmpeg is unable to detect the Kpbs. Hence it is re-encoding the audio track. Note the "DEBUG:pyTivo.video.transcode:failed at aKbps" and the later on aKbps=None.
I suppose I could say if I don't have an aKbps but I'm remuxing is to mp4 then it's ok but this is part of the standard pyTivo audio algorithms and I'm loathed to change this without understanding the implications for other systems.
Can you update the mkv file to contain the correct info or perhaps try a different version of ffmpeg?
I'm guessing this is the same problem you are having with the other files you thought might be re-encoding the audio. |

You may be right. I will try an older build of FFmpeg to see if they've had a design change. I have over a hundred of similarly made files so editing these is not really an option based on time required. |

I have been working on some personal additions to the remux code that I am hoping someone can help me with. What I have done is added an option for a user set temp work folder to remux the video in. The default code is to keep the .pyTivo-temp file in the same folder as the original file however this is very slow when using a network share. The file has to be read from the network, processed, and written back over the network, only to be read again when pushed. With a temp folder set to the local drive it cuts out much of this and speeds up the remux 4x for myself.
I have completed all the necessary edits except for sending the proper URL to the tivo mind server. I am not really able to follow where this is getting created. Right now in transcode.py - mp4_remux I am returning newname to video.py as:
| Code: |
outFile = os.path.join(temp_path, file + '.pyTivo-temp')
newname = outFile
|
This is returned to video.py and sets f['name] = new_path and here:
| Code: |
url = f['url'] + quote(f['name'])
|
is where I have issues. It seems to add my full path to the original file share path which creates a file not found error.
I suppose I need to create a conditional test to set the proper URL but I am unsure which function to use that converts my path into a pushable URL.
Does anyone have recommendations? Once I have this complete I will post my edits up in case anyone else wishes to use them. |

It looks like push() function is where it is joining a base url with the share info:
| Code: |
baseurl = 'http://%s:%s/%s' % (ip, port, container)
if config.getIsExternal(tsn):
exturl = config.get_server('externalurl')
if exturl:
baseurl = exturl
else:
ip = self.readip()
baseurl = 'http://%s:%s/%s' % (ip, port, container)
path = self.get_local_base_path(handler, query)
files = query.get('File', [])
for f in files:
file_path = path + os.path.normpath(f)
queue.append({'path': file_path, 'name': f, 'tsn': tsn,
'url': baseurl})
|
I'm not certain how to interpret what it is doing though. It seems really entangled with a lot of things that I may break if I change. |

I can do a temp directory patch, give me a day or so.

hmm alright. Well here is what I have done so far in case it is useful for you. Everything is done except integration into video.py and a function in transcode.py that may not work on windows (hadn't gotten around to changing it yet.) I haven't tested it with metadata yet either.
config.py
| Code: |
def get_temp(fname):
logger = logging.getLogger('pyTivo.config')
if config.has_option('Server', fname):
tpath = config.get('Server', fname)
tpath = os.path.normpath(tpath)
if os.path.exists(tpath):
return tpath
logger.error('Bad %s path: %s' % (fname, tpath))
return None
|
transcode.py - mp4_remux function
remove @line 691
| Code: |
outFile = inFile + '.pyTivo-temp'
newname = basename + '.pyTivo-temp'
|
and add
| Code: |
temp_path = config.get_temp('temp_path')
file = inFile.split('/')[-1] # may not be mswindows compatible
if temp_path:
outFile = os.path.join(temp_path, file + '.pyTivo-temp')
newname = outFile
else:
outFile = inFile + '.pyTivo-temp'
newname = basename + '.pyTivo-temp'
|
help.txt in plugins -> settings
| Code: |
temp_path
Default Setting: None
Valid Entries: Any operating system path
Required: No
Skill: Basic
Description: Sets the base path to temporarily store your media content
that is being remuxed before being sent to your TiVo. If content is located
on network share this will significantly speed up the remux. If not set
or the path is not valid pyTivo will use the existing base path of your
media content for temporary storage.
Example Settings: Windows = C:\videos\temp | Linux = /home/user/media/temp
Available In: Server
