Rather than listing the Internal Speakers as an output device, my MBA only shows “Headphones” in “Headphone Port.” Restarting the computer did nothing, and resetting the PRAM seemingly did nothing.
I cannot upload a WebM file containing OPUS audio and a still image (a png file) as VP9 video to Youtube, Youtube says :
The video has failed to process. Please make sure you are uploading a supported file type.
This google page says WebM is supported.
I used ffmpeg to create the WebM file with the following line :
$ ffmpeg -i myOriginialPureAudioFile-CUT.opus -i myAudioFile.png -ac 2 -af aresample=48k -b:a 128k -r ntsc -s 640x360 myAudioFile.webm
The resulting WebM file looks like this :
$ ffprobe myAudioFile.webm Input #0, matroska,webm, from 'myAudioFile.webm': Metadata: ENCODER : Lavf57.83.100 Duration: 00:06:00.01, start: -0.007000, bitrate: 104 kb/s Stream #0:0: Video: vp9 (Profile 0), yuv420p(tv, progressive), 640x360, SAR 1:1 DAR 16:9, 29.97 fps, 29.97 tbr, 1k tbn, 1k tbc (default) Metadata: ENCODER : Lavc57.107.100 libvpx-vp9 DURATION : 00:00:00.040000000 Stream #0:1(eng): Audio: opus, 48000 Hz, stereo, fltp (default) Metadata: title : unnamed ENCODER : Lavc57.107.100 libopus DURATION : 00:06:00.008000000
I tried different standard frame rates, bit rates, resolutions and audio sampling frequencies for half of my weekend, nothing seems to satisfy YouTube, can you please help me ?
No audio in final cut pro shared QT video
So I made a video on final cut pro but when i used all the default settings for sharing as a master file into my desired location it makes the video but in lower quality though i specifically set it as 1080p as in the default and the audio does not come with the video. How do i fix this?
I was given a very old Compaq Presario laptop and asked to make it usable. It had Windows XP and a lot of viruses; the audio was horrible, with too much noise in output.
I had a Windows 2000 Installation CD, hence decided to wipe out the hard disk and install Windows 2000. I planned to copy over lots of MP3 content and very old videos with VLC 1.1.11 installed. If the audio was still bad, I would attach some external speakers.
Installation of Windows 2000 went well, VLC 1.1.11 also got installed.
Now when I tried playing some MIDI content, VLC threw error about some Entry Point not found in kernel32.dll (I will try to fix this by trying out VLC 0.9.9, but this Post is not about that)
I tried Windows Media Player and it said “no audio devices are installed”
What could be the problem ?
How do I troubleshoot it ?
In case this is a software Issue, how do I get the appropriate Drivers for the sound card ?
In case this is a hardware Issue, Is there any way out ?
