i want to ask if there is any option to just merge multiple fragments downloaded from HBO GO app and mux it to some normal format like mkv or mp4??? Because these fragments has no file type. Some script, program, guide ??? It looks like this
for video: Fragments(video=0), Fragments(video=10000000), Fragments(video=20000000), Fragments(video=30000000), Fragments(video=40000000), Fragments(video=50000000)
...for audio Fragments(audio_eng_st_dub=0), Fragments(audio_eng_st_dub=20201361), Fragments(audio_eng_st_dub=40402721), Fragments(audio_eng_st_dub=60604082)
...for text is simillar.
youtube-dl doesnt support HBO GO direct download so if anybody can help me with it ???
Thank you
They are probably fragmented mp4, You can just concat them with the init fragment and many players can play it.
However HBO use DRM, so you will never be able to play these files.

I'm building a tool to edit audio with the Web Audio API.
Here is where I'm stuck:
...
source
.connect(gainNode)
.connect(analyser)
.connect(analyser2)
.connect(audioCtx.destination);
};
What I've written (which ends with the code above) successfully allows the user to upload a file, apply effects, and listen to it on play(). How would I then allow the user to click a button to export the results to a WAV file?
I've tried several methods online that have not worked for my use case.
Please let me know if more code is needed. Thank you for taking a look!
If you want a WAV file, I think you have to do that yourself. WAV files are quite simple. In this case, you'll need to add either a ScriptProcessorNode or AudioWorkletNode just before the destination to capture all the audio and convert it to a WAV file that can be downloaded.
If a compressed file is ok, you can look into MediaRecorder to save the data for you.
I ended up solving this by writing an entirely different script to download the file using OfflineAudioContext.
My original script plays the audio with effects, and the second script downloads it with the same effects. Now to figure out why there is latency on the effects while using OfflineAudioContext.
I am having trouble doing what the title said. My goal is to be able to add any desired effects to your recording, save the modified audio, then send that to a server.
I have searched the fourms and came across these threads:
viewtopic.php?f=7&t=13029&p=45362&hilit=saving#p45362
viewtopic.php?f=7&t=12660&p=44586&hilit=saving#p44586
viewtopic.php?f=7&t=13178&p=45746&hilit=saving#p45746
After reading those, I see it is possible to save the modified audio, but can it only be saved as a wav? Like I said after it is saved it will be sent to a server, so size is a big deal and wavs are relatively big compared to other formats. Ignoring that fact, I tried to implement FMOD_OUTPUTTYPE_WAVWRITER and I cannot get that to work; are there any good examples of using it? I looked though the examples in the library but I didn't see any..
But the basic structure of the app is to record, turn some switches off and on to see what filters you want, preview it, then press a button "Save" that will save it. What would this save function consist of?
Any help appreciated, thanks.
Using FMOD_OUTPUTTYPE_WAVWRITER is fairly straight forward, you set the type via System::setOutput, specify the output file via System::init extradriverdata. The extradriverdata should be an absolute path to a writable area of the device such as the documents directory. After you have finished playing, call System::release and the file will be complete.
The other option for recording wave data with effects is by creating a custom DSP and connecting it to the channel playing the recorded data. You will then get regular callbacks giving you float data that you must write out to disk yourself. You can find examples of DSPs and writing wav files in the dsp_custom and recordtodisk examples respectively.
Finally note that FMOD doesn't come with the facility to write compressed audio to disk, you will need another API to achieve this goal.
You can save as an AAC file via the ExtAudioFile API.
I need to stream both audio and video files from the Red 5 server. By default Red 5 only supports flash, but I need to add support for other file types too.
I need to dynamically (on the run time) transcode the media file in one format to desired formats as per client request. Is it possible ? How to go for it ? I have been reading of vlcj project, but dont know how to integrate them.
If audio / video transcoding is not possible in Red 5, is there any other open source alternative I can look forward to ?
Any help will be really appreciated...
Thanks !
Check out the StreamableFileFactory bean inside your red5-common.xml, to see what kind of files can be streamed by default (flv, mp3, mp4, m4a). If you copy any of these files in your red5 service's streaming directory, it will be able to play it.
If the source you need to stream is in different format (like youtube uploads), then the best way for you to go is ffmpeg.
You build it to your server, then
from inside your red5
service check whether there are any
unsupported files in your streaming
directory (should be a scheduled job), and
if so, use ffmpeg with the proper
parameters to convert the new files
to streamable formats.
that's it.
I would like to create a quicktime movie from a sequence of still frames via perl. It seems like there should be a relatively simple way to do this, but so far I have not found it. Things I've tried:
Reading the Quicktime file spec and creating the movie file from scratch. This low level approach has worked well for me in the past with TIFF and PDF file formats, but Quicktime seems dauntingly complicated.
Looking at the various quicktime-related perl modules. So far I haven't found one that lets me do what I want (images --> movie) with a minimum of fuss.
Using Applescript and Quicktime Player. This would probably work if I paid for Quicktime Pro, but I'd prefer not to do that.
I'm interested in any suggestions (even non-perl-based ones) for a relatively simple way to assemble a sequence of images into a quicktime movie.
Video encoding isn't really an ideal job for perl -- there are a lot of pieces to put together. I would suggest just using mencoder -- you can use an input of e.g. -mf type=png:fps=30 mf://frame*.png, and an output format of e.g. -of lavf -ovc lavc -lavcopts vcodec=libx264 -o whatever.mov. If you want to dub in audio you can use -audiofile whatever.mp3, and then either -acodec copy if you want it to be MP3 in the movie as well, or perhaps -acodec faac (and -faacopts) if the audio format in the movie needs to be AAC. There are lots of different options to tweak and things to learn but it's pretty much the ideal tool for the job. FFmpeg is nicer to use in a lot of ways, but it doesn't have the mf:// input mode, which makes assembling a video from frames a lot more painful.
I am making a simple game in order to learn a new language. I am in the process of collecting some music for the game and would like to use the MIDI format so that I can control the flow of the track (i.e., I would like to have an introduction that only plays once and does not play again when the song loops.)
I am having a tough time finding information on how to modify existing MIDI files so that they may send a control change signal to the synthesizer. Has anyone had experience with this?
I think that I should have been more clear with my original question. I am using an existing game engine which takes care of playing the music. I am under the impression that this control change value must be embedded directly in the MIDI file itself as I have no control over the synthesizer. From the manual:
MIDI files are played via the
DirectMusic Synthesizer. If a BGM MIDI
file contains the control change value
111, that value is recognized as where
the song will start repeating after it
reaches the end.
I wish I could do it programmatically. I suppose what I am after here is some sort of editor which will allow me to modify the MIDI file that I already have.
Sounds like what you really want is a midi editor
try looking in the Midi 1.0 spec
Here's a table of the control change messages though it looks like you're looking for a way to do this in software. yes?
you could try just sending it as raw midi data (ie. the messages on that table)
looking over your question again... my answer is not that useful...
what I would do if I were you is separate the introduction into it's own file and then you have a file containing just what you want to loop.
you could also look at the spec for the Standard Midi File format (SMF)
DirectMusicProducer is probably your best free option if you are playing using DirectMusic. I don't believe the MIDI record feature will include control changes, but your engine may support playing segment files which are much more flexible.
The only MIDI sequencer I use cost around $300 (USD) about 10 years ago (and no longer appears to exist), but I am not aware of any good quality free MIDI file sequencers. (Note that "MIDI editor" is probably different to "MIDI file editor" or "MIDI sequencer")
