Bash script to convert video files into Google Chromecast supported format.

chromecastize's Issues

Error when mediainfo doesn't return number of audio channels

I have a few videos using the mp4 container that give an error when using the --stereo option:

Processing: /mnt/videos/testvideo.mp4
- general: MPEG-4 -> mkv
- input video profile: [email protected]
- video: AVC -> copy
/usr/local/bin/chromecastize.sh: line 179: [: -gt: unary operator expected
- audio: Ogg -> copy
- video length: 02:22:06.744

The file is not converted to stereo. It seems to happen because mediainfo cannot find the number of audio channels.

Default to Opus for the audio codec

We are still defaulting to Ogg Vorbis as the audio codec but this has been superseded by Opus years ago. Opus is fully supported in all chromecast devices.

Handle more extensions

Handle extensions such as .mov, .wmv etc.

See e.g. http://www.moviecodec.com/solutions/video-file-extensions-5092/

Filenames with spaces

It appears that with the latest commit filenames with spaces are no longer processed.

An up-to-date version ?

Hi ... It's going to be a long time since chromecastize hasn't be updated ...

What version (or fork one ?) is the best (which contains all fixes) ?

Thanks in advance

Handle files with multiple audio tracks

Directories containing filesnames with whitespaces don't work

If a directory contains movies files which have whitespace in their names chromecastize fails to correctly process the files because the central loop for f in $(find ...) splits strings by whitespace (which is the default in bash). I workaround this problem with another script which does the find -type f .. and sets IFS=$'\n' which makes the for loop break list items by new line...

WebM and VP8 are now supported

Recent firmwares support WebM containers and VP8 encoding. Ref. https://developers.google.com/cast/docs/media

FLAC 5.1 is not supported

According to https://developers.google.com/cast/docs/media#audio-codecs FLAC audio up to 24-bit/96kHz should be supported, but this does not seem to be the case for a movie that contains a 6 channel (5.1) FLAC stream.

The documentation doesn't mention a limitation on the number of channels, but we can perhaps automatically convert FLAC audio streams that have more than 2 channels.

Chromecastize has issues with files with 2 spaces in the name

Had a couple of file with double spaces in the name. After running chromecastize against those files, chromecastize doesn't see that he already has converted these files. After removing the files, there was no issue anymore.

Audio bitrate lower

After the conversion the audio bitrate is lower than before. For example, with a movie I had first 640Kbps and than 276Kbps. It's not a big problem, but I'll search for a solution.

Provide solution for `.VOB` files

Currently .VOB files are ignored, but ideally there should be way how to process them too.

Is the avconv check necessary?

I'm running arch and since there's no avconv utility, I simply removed it from the check and everything seems to be working as it should. Is the check for avconv necessary for other distros? If not, I'd like to propose it be removed, I can issue a pull request...

help casting/converting a file

First of all I would like to thank you for your time and help to the community.

I think your script is really helpful, but I need help for a specific file I cannot stream via Chromecast from a Synology station.

First of all chromecastize says it should be playable:

./chromecastize.sh videofile.mkv
===========
Processing: videofile.mkv
- general: Matroska -> ok
- video: AVC -> copy
- audio: AAC -> copy
- file should be playable by Chromecast!

If I try to force it to mp4 I get this output

./chromecastize.sh --mp4 videofile.mkv
===========
Processing: videofile.mkv
- file was generated by `chromecastize`, skipping

If I try to force it to mkv I get this output

./chromecastize.sh --mkv videofile.mkv
===========
Processing: videofile.mkv
- file was generated by `chromecastize`, skipping

Any suggestion?

Make `chromecastize.sh` runing on Synology Diskstation

Allow users to customize the default configuration

The current lineup of Chromecast devices have different capabilities. It would be great to allow people to customize the defaults for chromecastize to match their own device.

For example users with a Chromecast Ultra might want to always encode using h265, while users with a 3rd generation Chromecast might want to change the h264 level to 4.2.

We can check if there is a config.sh file in the users' config folder and source it if present. In order to inform users about the possible configuration options and suggest sane defaults for the different devices we can also ship an example file.

Error when passing new `--force-vencode` option

When I try to pass the new --force-vencode option that was added in #49 I am getting the following error:

Unrecognized option 'preset fast -profile:v high -level 4.1 -crf 17 -pix_fmt yuv420p'.
Error splitting the argument list: Option not found

This is caused by Bash automatically escaping the DEFAULT_VCODEC_OPTS variable with quotes because it contains spaces.

Latest 1.40.156414 Chromecast firmware has trouble with multichannel audio

Ref. https://issuetracker.google.com/issues/136195374

The latest firmware doesn't play multichannel Vorbis and Opus audio when streamed over UPnP. It does seem to work fine through other delivery methods, like playing through Chrome or VLC.

Maybe we can add a --stereo option that people can use if they are affected by this. It could also be useful in general for people that do not have a surround setup.

Automate conversion of all files in a directory

Keep the original file for torrent seeding

Hi! I didn't knew that chromecastize existed so I did it myself and used it for years; but luckily I found your implementation and that's what I'm using nowadays :)

I find important to keep the original file without changing its name to keep torrent-seeding it.

I was wondering if there's any configuration option for this or if you would be interested in this PR.

We could add a '-chromecast' suffix to the filename, before the extension.

Thanks for all your work :))

ffmpeg install not recognized

I installed ffmpeg on linux 14.04 server using this guide: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

ffmpeg appears to be running fine.
When I enter command "which fmpeg" I receive response: /home/myusername/bin/ffmpeg
When I run chromecastize, I receive an error that ffmpeg is not installed as follows:
avconv (or ffmpeg) is not available, please install it

Forgive me, as I am noob. Don't know if this is the right way to report this, or ask for help. Perhaps my install of ffmpeg needs to be moved somewhere else?

Call `mediainfo` just once to get all required info

Currently mediainfo gets executed multiple-times, which is unnecessary. It can be called just once and parse all necessary details.

Still level 5.2

Do you guys have some idea? Thank you.

Conversion fails if `$HOME` folder is not accessible

I am running chromecastize on a headless system that does not have any home folders for the users on the system. If I try to convert a file, this fails when it tries to write to the processed_files which is hardcoded to the path ~/.chromecastize/processed_files.

$ chromecastize my-video.mkv 
mkdir: cannot create directory ‘/home/pieter’: Permission denied
touch: cannot touch '/home/pieter/.chromecastize/processed_files': No such file or directory

- failed to convert 'my-video.mkv' (or conversion has been interrupted)
- deleting partially converted file...

I think to solve this we should do two things:

1. Provide an option to override the location of the config folder.
2. Check if the processed_files file is writable before starting the conversion, and abort the process if it is not. This will alert the user right away of the problem, and not after waiting for the conversion to complete.

Commandline options requests: threads number and audio track selection for ffmpeg

Hi!

I have two cores, I'd like to use those for transcoding: https://superuser.com/questions/155305/how-many-threads-does-ffmpeg-use-by-default
Also I have multiple audio video and I'd like to convert only one of those, can You add option to select audio track to convert?
https://superuser.com/questions/639402/convert-specific-video-and-audio-track-only-with-ffmpeg

Thank You, great tool!

Multi thread options

I'm not sure if your app is using multithread. Avconv/ffmpeg have -threads auto option or even specifying the amount of threads to use -threads 2. You can add these options to the app in order to get shorter codification times.

*.ok Invalid argument

This is the error:

Support deletion of `.bak`files

Currently original file gets renamed to .bak. Would be nice to support removal of original files, e.g. by renaming them to unique extension such as .ccbak and then removing by find command

Processing stops when mediainfo returns an error for a file

I am trying to process a large number of files on my NAS. It appears that some files cannot be parsed successfully by mediainfo and return an error code. When this happens I get the following message, and the process aborts:

'' is an unknown codec. Please add it to the list in a CONFIG section.

We could check the exit status of mediainfo and skip the file if it returns an error. In order to better inform the user which files were skipped we could maintain a log file.

Any way to add usage of nvidia gpu usage?

Hi!

This script has helped a lot. But I was wondering if its able to also use h264_nvenc to convert faster?

Detect permissions disallowing to rename a file

Choose output container

It would be great if we could choose output container (e.g. mp4 instead of mkv)
