Restreaming and transcoding a hls stream with FFMPEG.WASM fails due to tcp connection
13 juillet 2021, par Hoang NguyenI'm trying to implement a feature which is live transcoding a hls stream (h265) to another hls stream (h264) so the video can be played using html5 video player as we know that h265 is not supported on browsers. Quick summery of my tech stack :


-Electron desktop app as the client.
-FFMPEG.WASM library : https://ffmpegwasm.github.io/


(*) The on-the-fly transcoding is supposed to happen right on the client side.


My dev enviroment :


"devDependencies": { "electron": "^13.1.5", "electron-packager": "^13.0.1", "electron-winstaller": "^2.7.0" }

There are 2 ways to use this library, one is as normal html script, and the other is nodejs style which I have tried both and get different errors (though they are all about connection) :


(*) Regular JS way


<code class="echappe-js"><script async defer src="https://unpkg.com/@ffmpeg/ffmpeg@0.10.1/dist/ffmpeg.min.js"></script>


<script>&#xA; async function loadPlayerHEVC() {&#xA;var resource = &#x27;http://10.70.39.32:80/streams/60dd68fdc88f570012526657/stream/60dd68fdc8....526657.m3u8&#x27;&#xA; const { createFFmpeg } = FFmpeg;&#xA; const ffmpeg = createFFmpeg({ log: true });&#xA; const { fetchFile } = FFmpeg;&#xA; await ffmpeg.load();&#xA; await ffmpeg.run(&#x27;-re&#x27;,&#x27;-i&#x27;, resource, &#x27;-vcodec&#x27;, &#x27;libx264&#x27;, &#x27;-acodec&#x27;, &#x27;copy&#x27;, &#x27;-f&#x27; ,&#x27;hls&#x27;, &#x27;-hls_list_size&#x27;, &#x27;3&#x27;, &#x27;-hls_wrap&#x27;, &#x27;5&#x27;, &#x27;playlist.m3u8&#x27; );&#xA; // ffmpeg.exit(0);&#xA; }&#xA; </script>




(*) Nodejs way


async function tester(url)
{
 const { createFFmpeg, fetchFile } = require('@ffmpeg/ffmpeg');
 const ffmpeg = createFFmpeg({ log: true });
 await ffmpeg.load();
 await ffmpeg.run('tcp','-re', '-i', url, '-vcodec', 'libx264', '-acodec', 'aac', '-f', 'flv', '-hls_list_size', '3', '-hls_wrap', '5', 'playlist.m3u8');
 // ffmpeg.exit(0);
}




URL for testing


You guys can use this public stream to reproduce the scenario : http://113.163.94.245/hls-live/livepkgr/_definst_/liveevent/thbt.m3u8


Any help would be much appreciated.

FFMpeg to resize any video to fit 1080x1920 vertical, without cropping, instead by shrinking and adding blurred borders ?
19 mars 2021, par MaxI found some posts explaining how to turn any video horizontal by adding blurred borders using FFMpeg, but I want to convert videos to vertical 1080x1920. I don't want it to enlarge the video, nor crop if a dimension is bigger than either 1080 or 1920 dimension. Instead, I want it to shrink the video until it fits fully inside 1080x1920, and then I want it to add blurred borders to the empty areas.


This is the snippet I found, but when I tried reversing the numbers, it actually cropped the video.


ffmpeg -I input.mp4 -lavfi "[0:v]scale=1920*2:1080*2,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg];[0:v]scale=-1:1080[ov];[bg][ov]overlay=(W-w)/2:(H-h)/2,crop=w=1920:h=1080" output.mp4

ffmpeg concat vertical video, different dimensions [duplicate]
16 octobre 2020, par MorrisContext :
3 input videos :


foo.mov: 1080x1920 (vertical, NOT horizontal) with audio.

bar.mp4andfiz.mp4: 480x360, with audio.
(Note :.mp4, differs from.mov)

Goal : to concat all 3 videos. Output
out.mp4should be 480x360. Squeezefoo.movbut keep its aspect ratio, taking up 100% height, but the slim video should stand only in the center, with left and right sides being black (or other color) void.foo.movshould not be cropped.

I currently have this command below (added new-line characters for better visualization) for concating, but need to fill the missing code at
PLACEHOLDER1to generatev0, such thatv0is resized to 480x360 like described above. If my attempt so far is correct, please help completePLACEHOLDER1; else, please offer a better solution with explanation.

ffmpeg 
-r 24 -i foo.mov 
-r 24 -i bar.mp4 
-r 24 -i fiz.mp4
-filter_complex 
"[0:v] PLACEHOLDER1 [v0];
[v0][1][2] concat=n=3:v=1:a=1 [v][a]" 
-map "[v]" -map "[a]" out.mp4


Running


ffmpeg -n -i foo.MOV -i bar.mp4 -i fiz.mp4
