This is only with WebGL
Errors during import of AudioClip Assets/Audio/background.wav:
FSBTool ERROR: Failed with error code 80004001
FSBTool ERROR: Failed encoding audio clip '/Assets/Audio/background.wav' to AAC. Possibly the file is too short. Try to append silence such that the length becomes greater than 256 samples.
I can't add the audio click on WebGL, but on others platforms work perfectly.
I can't add the audio click
Please help.
The error tells you that the Audio-Sequence is too short. Try adding silence (as suggested) to increase the samples of your file.

I followed the top answer in this StackOverflow post to use ffmpeg-python extract a .wav file from a YouTube URL (into the pcm_s16le codec), which was played successfully by my local audio player (Mac's Music).
However, as I tried to read it using scipy.io's wavefile,
samplerate, data = wavfile.read(wav_fname)
the following error message is thrown:
"WavFileWarning: Reached EOF prematurely; finished at 1192015 bytes, expected 4294967303 bytes from header."
May anyone suggest what's going on?
I have successfully extracted a .wav file which is successfully read by my local music player. However, it is failed to be recognized by scipy.io's wavefile. And I am not sure why.
My MP4 file issue is a bit complicated, so I have created a very simple scenario to help me diagnose it step by step.
I can create a working MP4 file that works flawlessly. The following is its structure shown by Mp4Explorer:
For debugging purpose, I removed the media data box mdat, and al stts, stsz,stss, stsc, stco boxes and kept everything else the same. This means the MP4 file has no media data. It just has some metadata.
This file is named error.mp4. If I run:
ffprobe "error.mp4"
I get the following error:
[mov,mp4,m4a,3gp,3g2,mj2 # 00000286e763ef00] Could not find codec parameters for stream 0 (Video: h264 (avc1 / 0x31637661), none, 1280x800): unspecified pixel format
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
Could anyone shed some light on this error? Why is it "Could not find codec parameters for stream 0"? If I remove the video track and leave the audio track as is, ffprobe will be happy with no errors.
I am using Tika server to fetch metadata and contents of various file formats. I am using server with fileUrl enabled.
When parsing .mov file which are created using quicktime screen record, it gives me the following error.
Text extraction failed (null) org.apache.tika.exception.TikaException:

The size of the file is just 20Mb. Other type of .mov files with
content-type="video/quicktime"
is getting parsed with out any error. I connected the debug port and i see that it fails when converting to new IsoFile().
Any help to fix this is highly appreciated.
I start the server as shown below.

Hi I am facing an issue with AVAssetEXport. I am trying to combine many videos one after another, let's say 20 - 30, adding each asset as a track of VideoMutableCompositon with insertTimeFrame:
|video1|video2| ... |videoi| ... |videoN|
If I exceed 15 - 16 videos and I export,I get the following error:
failed: Error Domain=AVFoundationErrorDomain Code=-11839 "Cannot Decode" UserInfo={NSLocalizedDescription=Cannot Decode, NSUnderlyingError=0x1c8044620 {Error Domain=NSOSStatusErrorDomain Code=-12913 "(null)"}, NSLocalizedRecoverySuggestion=Stop any other actions that decode media and try again., NSLocalizedFailureReason=The decoder required for this media is busy.}
I am sure that this is not a RAM issue since I am using iphone8 plus and also xcode show a low RAM activity.
If I reduce the number of videos to 5 - 8 everything works great...
Is there a limit on adding video tracks?
Can anyone help me to achieve this goal?
Finally I found out the cause and was my bad!
The problem was that I was looping through AVMutableCompositionTrack.
So that each video was on a different track and probably that caused a lack of resources.
Right now I created only 2 tracks: 1 for video and 1 for audio.
All my videos are stitched with time ranges.
Thank you guys!!!!
I'm attempting to write an AAC file from the output stream of an AUGraph, and on playback my file only plays a buzzing noise, and I get the error ExtAudioFileWriteAsync -50.
I'd like to know what it means so that I can search for and destroy the problem.
Thanks to any Core Audio ninjas that can hook a brother up.
In case anyone else has this problem, the -50 error is a kAudio_ParamError error, defined in CoreAudioTypes.h.
Therefore, one of the parameters being passed to ExtAudioFileWriteAsync must be faulty.
