Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

swscale/aarch64 : add hscale specializations
26 mai 2022, par Swinney, Jonathanswscale/aarch64 : add hscale specializations
This patch adds code to support specializations of the hscale function
and adds a specialization for filterSize == 4.ff_hscale8to15_4_neon is a complete rewrite. Since the main bottleneck
here is loading the data from src, this data is loaded a whole block
ahead and stored back to the stack to be loaded again with ld4. This
arranges the data for most efficient use of the vector instructions and
removes the need for completion adds at the end. The number of
iterations of the C per iteration of the assembly is increased from 4 to
8, but because of the prefetching, there must be a special section
without prefetching when dstW < 16.This improves speed on Graviton 2 (Neoverse N1) dramatically in the case
where previously fs=8 would have been required.before : hscale_8_to_15__fs_8_dstW_512_neon : 1962.8
after : hscale_8_to_15__fs_4_dstW_512_neon : 1220.9Signed-off-by : Jonathan Swinney <jswinney@amazon.com>

Live stream doesn't seem to be passed to AWS correctly
12 août 2024, par NoobAmII'm trying to stream my live video into Amazon IVS and I don't see it on the live channels.


Is it possible I have a mistake in my FFMPEG configuration ?
I'm expecting to see this in my playback url or on the console screen for playback but I see nothing at the moment.


As I understand it, shouldn't I see some kind of playback in the live channels if a stream is being sent that channel ?


` async sendDataToIvs(channelArn: string, payload: any): Promise<void> {
 const injestServer = '***.global-contribute.live-video.net';
 const streamKey = 'sk_us-east-1_*****';
 
 const ffmpeg = spawn('ffmpeg', [
 '-re', // Read input at native frame rate
 '-i', '-', // Input from stdin (live stream data)
 '-r', '30', // Frame rate
 '-c:v', 'libx264', // Video codec - H.264
 '-pix_fmt', 'yuv420p', // Pixel format
 '-profile:v', 'main', // H.264 profile
 '-preset', 'veryfast', // Encoder quality setting
 '-x264opts', 'nal-hrd=cbr:no-scenecut', // Additional x264 options
 '-minrate', '3000', // Minimum bitrate
 '-maxrate', '3000', // Maximum bitrate
 '-g', '60', // GOP size
 '-c:a', 'aac', // Audio codec
 '-b:a', '160k', // Audio bitrate
 '-ac', '2', // Audio channels
 '-ar', '44100', // Audio sample rate
 '-f', 'flv', // Output format
 `rtmps://${injestServer}:443/app/${streamKey}` // Output destination
 ]);
 
 ffmpeg.stdin.write(payload, (err) => {
 console.log(payload)
 if (err) console.error('Error writing payload to FFmpeg stdin:', err);
 });
 
 ffmpeg.on('close', (code) => {
 console.log(`FFmpeg process exited with code ${code}`);
 });
 
 ffmpeg.stdin.on('error', (err) => {
 console.error('Error writing to FFmpeg stdin:', err);
 });
 
 ffmpeg.stderr.on('data', (data) => {
 console.error(`FFmpeg error: ${data}`);
 });

Why does ffmpeg hang indefinitely when composing videos ?
11 octobre 2022, par Brendan HillI am executing ffmpeg commands in a Java microservice (which runs dockerised in kubernetes in a temporary pod created by KEDA from an Amazon SQS queue... but unlikely to be relevant).


About 30% of the time, the ffmpeg process hangs indefinitely :



/usr/local/bin/ffmpeg 
 -i /tmp/transcode-3b928f5f-3cd9-4cd6-9175-b7c1621aa7ce13592236077853079159/person1.mkv 
 -i /tmp/transcode-3b928f5f-3cd9-4cd6-9175-b7c1621aa7ce13592236077853079159/person2.mkv
 -filter_complex [0:v][1:v]hstack=inputs=2[v];[0:a]aresample=async=1000[0sync];[1:a]aresample=async=1000[1sync];[0sync][1sync]amix[a] 
 -map [v] 
 -map [a] 
 -c:v libx264 
 -crf 18 
 -ac 2 
 -vsync 1 
 -r 25 
 -shortest /tmp/transcode-3b928f5f-3cd9-4cd6-9175-b7c1621aa7ce13592236077853079159/composed.mp4



This causes the Java code to wait indefinitely :



 Process proc = Runtime.getRuntime().exec(cmd);

 StreamConsumer outConsumer = new StreamConsumer(proc.getInputStream(), stdout);
 StreamConsumer errConsumer = new StreamConsumer(proc.getErrorStream(), stderr);

 // execute data read/write in separate threads
 outExecutor.submit(outConsumer);
 errorExecutor.submit(errConsumer);

 proc.waitFor() // Hangs indefinitely, with ~30% probability



It is not specifically about the video files because they generally work on retry (with similar 30% failure probability so sometimes several retries are necessary). Of course, since it hangs indefinitely instead of exiting with failure, it has to wait hours before we risk another retry.

Why is ffmpeg hanging indefinitely and how to fix ?


-
Can I get ffmpeg to fail early instead of hanging indefinitely (so I can trigger retry immediately) ?


-
I see many questions and posts about ffmpeg hanging indefinitely. Is ffmpeg inherently unstable ?
