Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

multiple GPU encoding use FFMPEG under multiple threads environment
8 septembre 2022, par shenuoHere is the application situation.
I want use 4 NV GPUs to carry out some calculation work (CUDA based), and encoding work (FFMPEG &NVEC), it works fine when they are in serial. But when I want them to be parallel. like this


void encodingwork(){
 #pragma omp parallel for num_threads(4)
 for (int i = 0; i < 4; i++) {
 cudaSetDevice(i);
 encodingwork();
 }
 }

 int main(){
 thread thd;
 for (int k = 0; k < N; k++) {
#pragma omp parallel for num_threads(4)
 for (int i = 0; i < 4; i++) {
 cudaSetDevice(i);
 cudawork();
 }
 if (k != 0)
 thd.join();
 thd = thread(encodingwork);
 }
 thd.join();
 }



an error will be thrown out from ffmpeg. just like


[AVHWDeviceContext @ 000002334959ac80] cu->cuMemFree((CUdeviceptr)data) failed -> CUDA_ERROR_ILLEGAL_ADDRESS: an illegal memory access was encountered

[hevc_nvenc @ 00000230c956b200] EncodePicture failed!: generic error (20):
Error sending a frame for encoding: -1313558101 (Unknown error occurred)



can anybody tell me what's wrong with this ?

How to tell if ffmpeg errored or not ?
12 juin 2015, par dvdmnThe Situation :
I’m using ffmpeg (via .net) to save video files. I can get the output from ffmpeg but I dont know how can I customize the output to have better result.My Problem :
My problem is, there is no certain difference between successful and failed operation.last line of success :
video:1006kB audio:134kB subtitle:0 global headers:0kB muxing overhead 0.943510%
last lines from fails
c :\x\test-9-8/30/2012-9:29:56-AM.mp4 : Invalid argument
rtmp ://cdn.tv/cdn-live39/definst/stream01 : Unknown error occurred
My Question :
Is there an option (or command line parameter) to add some sort of return code (200 : success, 500 : error, etc)Thanks !
PS : I saw this topic How to tell if ffmpeg errored ? but there is no number before/after last line. I think the last version doesnt have number anymore.
