Video recorded using Kurento is corrupted
10 avril 2023, par Pranjal LambaWe are using Kurento media server v6.6.1 to record a video conference. The web app client which runs on Chrome(Windows, OSX, Android) is using a modified version of one-to-one-call-advanced Kurento sample and the second client is an Android native application which is using Nubomedia webrtcpeer v1.1.1. Nubomedia webrtcpeer uses LibJingle built by io.pristine v11139(released on December 2015). The video and audio is recorded in two separate recorder endpoints by Kurento.


Video conference recordings generated using web app client/s are working properly. But sometimes the video generated using native application contains all the frames within initial few seconds. Please find below download link for the problematic video generated by our Android native application,


https://drive.google.com/file/d/1vOVk8hPuP_iOlQfsmMoqZLhICy-Jpcee/view?usp=sharing


We are testing this feature on a range of Android devices, Nexus 5(Android 6.0.1), Nexus 6(Android 7.1.1), Sony Xperia Z Tablet(Android 6.0.1), Samsung Galaxy Tab A(Android 5.0), OnePlus 3(Android 7.1.1), Xiaomi A1(Android 7.1.1). The issue randomly starts occurring on a bunch of these devices while the others work properly and vice-versa.


We are recording the videos with the following constraints,


Web app client


Minimum video width : 32

Minimum video height : 32

Maximum video width : 320

Maximum video height : 320

Minimum framerate : 1

Maximum framerate : 15

FFmpeg transcode GIF into Mp4 and Mp4 to AVI using GPU
9 octobre 2023, par CristianI'm trying to convert GIF animated to mp4 and mp4 to AVI with FFmpeg.


I started to use just the CPU, but I have to process millions of GIFs/mp4 content pieces. So, I started to have a lot of errors processing them, and it ended as a bottleneck. Therefore, I'm trying to use GPU to process the videos.


Converting GIF to mp4 with CPU, I run the following command :


ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4



Using the GPU I'm trying the following :


ffmpeg
 -y
 -hwaccel nvdec
 -hwaccel_output_format cuda
 -i gifInputPath
 -threads 1
 -filter_threads 1
 -c:v h264_nvenc
 -vf hwupload_cuda,scale_cuda=-2:320:240:format=yuv420p
 -gpu 0
 mp4VideoPath



The above command generates an exit status 1.


The following is the dmesg command log


Converting mp4 videos to AVI videos I'm running the following command


ffmpeg
-i videoInputPath
-vcodec rawvideo
-pix_fmt yuv420p
-acodec pcm_s16le
-ar 44100
-ac 2
-s 320x240
-r 4
-f avi
aviOutputVideoPath



For GPU I tried :


ffmpeg
 -y
 -hwaccel cuda
 -hwaccel_output_format cuda
 -i videoInputPath
 -threads 1
 -filter_threads 1
 -c:a pcm_s16le
 -ac 2
 -ar 44100
 -c:v h264_nvenc
 -vf hwupload_cudascale_cuda=-2:320:240:format=yuv420p
 -r 4
 -f avi
 -gpu 0
 aviOutputVideoPath



The following is the dmseg output is log

What should be the best command for converting the GIF into Mp4 and Mp4 into AVI based on CPU configuration using the GPU(Amazon Nvidia t4) for best performance, low CPU, and moderated GPU consumption ?


-
What are the best suggestions to Process these content pieces concurrently using GPU ?








Note : I'm using Golang to execute the FFmpeg commands.

Nomenclature #4519 : Renommage de terminologie (blacklist / whitelist)
20 juillet 2020, par RastaPopoulos ♥Pour le français, il me semble qu’il faut faire attention à quoi ça s’applique (par rapport à l’anglais qui est un peu la référence si on s’inspire des propositions des autres communautés) : ça ne s’applique pas au mot "liste".
Par exemple dans "allow list", ce n’est pas "allowed list", ce n’est pas la liste qui est approuvée, mais en forme longue la "liste des choses qui sont approuvées". À voir ce que ce serait en version courte… "liste d’approbation" ? mais ça fait un peu ampoulé et pas très usité j’ai l’impression. La forme "-ante" comme dans "bloquante", proposée par Maieul est peut-être la forme courte la plus proche…
