I am running FFmpeg from the command line as below...
ffmpeg -hwaccel_output_format cuda -c:v h264_cuvid -i rtmp://127.0.0.1:1935/live/$name -vcodec h264_nvenc -acodec aac -b:v 768k -b:a 96k -vf "scale=852:trunc(ow/a/2)*2" -tune zerolatency -crf 27 -f flv rtmp://localhost:1935/show/$name_480 -vcodec h264_nvenc -acodec aac -b:v 1920k -b:a 128k -vf "scale=1280:trunc(ow/a/2)*2" -tune zerolatency -crf 27 -f flv rtmp://localhost:1935/show/$name_720 -c copy -f flv rtmp://localhost:1935/show/$name_src
In theory, this should be decoding the source RTMP stream and then re-encoding to 480p and 720p (roughly) using the settings in the command, all on hardware. However, it seems that this is not the case as FFmpeg is still using roughly 50% CPU when running.
the card being used is a Nvidia Quadro p2000

Could the CPU utilization be correlated to the audio transcoding or would that be handled in hardware as well?
Any ideas?
The audio transcoding is done in CPU, but takes very little.
The source of your CPU load is likely your video filters. You're doing scaling, which can take a good deal of CPU.

i need to upload audio files (mainly WAV/FLAC) to an API. I validate these files by checking the output of ffprobe.
I have a media file at hand that seemingly fulfills all requirements of the API (Sample rate, bitrate, etc.) but has one anomaly that probably causes the rejection. (It plays fine though) The file looks like this:

Now obviously, this is caused by this weird converter software, that encodes these files and puts the wrong encoder in the file's metadata.
Now I have some questions:
Is this a required specification of flac files to include the encoder in the file metadata? Because the API documentation does not state anywhere if the metadata encoder has to match the actual encoder of the audio stream or what codecs are actually allowed.
How do I go about detecting such anomalies? Because currently, I have to copy the file with ffmpeg, check the encoder of the copied file. This process takes unnecessary compute resources.
Best regards,
Florian
If you want to verify the integrity of a FLAC file, you can do that with the flac tool. It is packaged with most Linux distributions, is on Homebrew for MacOS and there are binaries for Windows.
If you run flac -t somefile.flac or flac -t somedirectory/*.flac it will tell you about the integrity of the files.

My objective is to play a 4 video montage of different duration, and loop all the videos until the duration of the longest video. However I couldn't figure out how to do this.
The duration of each of the inputs is:
input1 (Duration: 00:00:00.24)
input2 (Duration: 00:00:01.98)
input3 (Duration: 00:00:04.02)
input0 (Duration: 00:00:04.02)
The following code produces a video with duration equal to that of input1:
ffmpeg -stream_loop -1 -i input0.mp4 -i input1.mp4 -i input2.mp4 -i input3.mp4 -filter_complex \
"[0]drawtext=text='input0':fontsize=20:x=(w-text_w)/2-200:y=(h-text_h)/2-150[v0];
[1]drawtext=text='input1':fontsize=20:x=(w-text_w)/2-200:y=(h-text_h)/2-150[v1];
[2]drawtext=text='input2':fontsize=20:x=(w-text_w)/2-200:y=(h-text_h)/2-150[v2];
[3]drawtext=text='input3':fontsize=20:x=(w-text_w)/2-200:y=(h-text_h)/2-150[v3];
[v0][v1][v2][v3]xstack=inputs=4:layout=0_0|w0_0|0_h0|w0_h0:shortest=1" -y output.mp4
One of my confusion is; when i swap the location of -stream_loop -1 and -i input0.mp4, my output video has the duration of input2.

My objective is to play a 4 video montage of different duration, and loop all the videos until the duration of the longest video. However I couldn't figure out how to do this.
Add -stream_loop -1 before each input except the longest input.
One of my confusion is; when i swap the location of -stream_loop -1 and -i input0.mp4, my output video has the duration of input2.
You're using shortest=1 in xfade. With -stream_loop -1 before input0.mp4 the shortest input becomes input2 (Duration: 00:00:01.98).
So I have been following this tutorial https://medium.com/nerdery/dslr-webcam-setup-for-linux-9b6d1b79ae22 and when I got to the point to actually take a photo with the camera I have no issues but when I get to try to capture with it I get

I want that this file (opus codec) can be accessible through RTP on my android phone.
I tried ffmpeg with next command:
ffmpeg -ar 44800 -i bon_jovi_loverboy.opus -acodec libopus -ac 1 -ab 96k -vn -f rtp rtp://127.0.0.1:5004 -loglevel 56
But got next error:
bon_jovi_loverboy.opus: Invalid data found when processing input
Full log:

What wrong? Thanks
UPD
I update ffmpeg and streaming looks successfully.
