lossless video to h.265 - [error] : main10 profile not compatible with i422 input chroma subsampling
24 février 2021, par spierce7I have a lossless
.movvideo and I'm trying to encode using h.265 for firetv and some other android tv devices. The spec that they support is :

Based on their native H.265 support, I'm trying to export a
Main 10 Profile with level 4.1.

The command I'm running is :


ffmpeg -i 001_lossless.mov -c:v libx265 -preset slow -profile:v main10 -level:v 4.1 -c:a aac -b:a 128k output.mp4


Which yields the following error :


x265 [error]: main10 profile not compatible with i422 input chroma subsampling.


What is the best way to work around this ? I can request the lossless video in different formats also, but I'm not exactly sure what to ask for.

Getting error "WebAssembly.Memory() : could not allocate memory" when running ffmpeg.wasm on android chrome browser

Code for ffmpeg :


const downloadWithFFMPEG = async () =>{
 const sourceBuffer = await fetch(recordingURL).then(r => r.arrayBuffer());
 await ffmpeg.load();
 await ffmpeg.FS(
 "writeFile",
 "input.webm",
 new Uint8Array(sourceBuffer, 0, sourceBuffer.byteLength)
 );
 await ffmpeg.run("-i", "input.webm", "-c", "copy", "output.mp4")
 const output = ffmpeg.FS("readFile", "output.mp4");
 var link = document.createElement('a')
 link.href = URL.createObjectURL(new Blob([output.buffer], { type: 'video/mp4;codecs=H264' }));
 link.download = this.data;
 link.click();
 recording = false;
}


Brief about problem :
The error only comes for android chrome browser. The same code works fine on pc/laptop chrome.
Have also enabled Webassembly-thread on chrome ://flags for android browser as someone suggested me to do it but still same error. Can someone help me ?
