i have issue with ffmpeg as usual :D. I have FFMPEG compiled (version N-90807-g00099ef0d0) with NVIDIA support (latest CUDA and latest NV Headers):

I have same version of FFMPEG compiled by the same way on another testing machine and there it is working. I tried to recompile/reinstall ffmpeg with the latest version, but result is the same.
Does someone know what could be wrong on my instance?
Thanks.
Fixed. The issue was in nvidia headers. Used version was extremely new. If you'll get this issue, just use the headers with tag n8.0.14.1 and then compile ffmpeg.
FFmpeg version of headers required to interface with Nvidias codec APIs:
git clone https://github.com/FFmpeg/nv-codec-headers.git
git checkout n8.0.14.1
make && make install

I'm building Electron app and I use ffmpeg to convert m4a or webm files to mp3, and also to merge video only mp4 with m4a audio file to mp4.
I am able to achieve this using [media-autobuild-suite] (https://github.com/jb-alvarado/media-autobuild_suite), using light build option, but the size of static files is arround 20mb and I'would like to shrink it a little bit more. I've compiled ffmpeg and ffprobe with this configuration.

Any ideas what else should I include into this static file?
No need to disable things piecemeal: just use --disable-everything then enable what you need.
Here's an example you can start out with:
./configure
--disable-everything
--disable-network
--disable-autodetect
--enable-small
--enable-decoder=aac*,ac3*,opus,vorbis
--enable-demuxer=mov,m4v,matroska
--enable-muxer=mp3,mp4
--enable-protocol=file
--enable-libshine
--enable-encoder=libshine
--enable-filter=aresample
Final binary size will be around 2-3 MB.
No need to enable any parsers: the selected decoders will automatically select whichever are required.
FFmpeg does not have a native MP3 encoder, so you'll need to use an external library such as libmp3lame or libshine. Since you mentioned Android I assumed you'll want libshine instead of libmp3lame to encode MP3.
Test thoroughly. I probably forgot something.
If you really want to go nuts then use --disable-all instead of --disable-everything and you'll additionally have to manually include the FFmpeg libraries that you want, but that's more work and more headache for not much return.
This will allow you to encode MP3 audio from most M4A and Webm inputs:
ffmpeg -i input.webm output.mp3
And will also let you re-mux MP4/M4V + M4A into MP4:
ffmpeg -i video.m4v -i audio.m4a -map 0:v -map 0:a -c copy output.mp4
We are converting seriously old .flv files to MP4 with FFMPEG. These are at least 10 years old.
Back then all were rendered with early versions of Adobe Premiere.
On desktop browsers all the files work and stream (...watching them feels like going back a century!)
But when requesting the videos on the same pages on mobile devices (android and ios) Video JS doesn't even show up.
Perhaps the codec is just too old, but I was wondering if there could be another reason when converting them with this line:
for i in *.flv; do ffmpeg -i "$i" "${i%.*}.mp4"; done
If not, is it possible to detect this in Video JS, so we can show an announcement that the video is only visible on desktops?
I hope someone here has this knowledge!

Thanks to #llogan's comments I can answer this one myself.
First, I upgraded ffmpeg to the latest version, and then did some research on the -movflags and +faststart.
I found a 2015 article with great info on how to convert .flv to .mp4 (https://addpipe.com/blog/flv-to-mp4/)
So, in order to make the new .mp4 files compatible with mobile devices, you need to add a profile and a level, like this:
in a batch convert:
for i in *.flv; do ffmpeg -y -i "$i" -movflags +faststart -profile:v baseline -level 3.0 "${i%.*}.mp4"; done
and for a single file:
ffmpeg -i filename.flv -movflags +faststart -profile:v baseline -level 3.0 filename.mp4
And then the terminal shows this line when converting:
Starting second pass: moving the moov atom to the beginning of the
file
That is needed, but the addition of the -profile and -level actually made the videos work on the mobile devices.
When I use ffmpeg with mjpeg encoder without hardware acceleration, everything works fine. I use following command:
ffmpeg -nostdin -rtsp_transport udp_multicast -allowed_media_types 'video' -i 'rtsp://MYIP' -ss 00:00:0.00 -f image2pipe -q:v 24 -vf scale=-2:480,format=yuv420p -c:v mjpeg -vframes 1 pipe:1
But, when I try to use mjpeg with hardware acceleration, I always get error:
ffmpeg -nostdin -rtsp_transport udp_multicast -allowed_media_types 'video' -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i 'rtsp://MYIP' -ss 00:00:0.00 -f image2pipe -q:v 24 -vf scale=-2:480,format=yuv420p -c:v mjpeg_vaapi -vframes 1 pipe:1

Can please anyone suggest right options to make it work?
so the problem was that my Intel CPU platform was old (Broadwell) and JPEG encoding is supported starting Braswell. Please see all supported codecs by platform on the page
After running the same command on the machine with Skylake CPU on it, it work from the first try :)
When you trying to leverage Intel's hardware encoding, you need to check TWO things
rather your particular intel support the encoder you want
rather your ffmpeg binary fetched from somewhere compiled with the hardware acceleration library or not.
To find out what kind of encoder your Intel support, you simply type:
vainfo|grep -i enc
it will list the encoder which your processor support. In my case, for example, it yields the following:
libva info: VA-API version 1.13.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_13
libva info: va_openDriver() returns 0
VAProfileMPEG2Simple : VAEntrypointEncSlice
VAProfileMPEG2Main : VAEntrypointEncSlice
VAProfileH264Main : VAEntrypointEncSlice
VAProfileH264Main : VAEntrypointEncSliceLP
VAProfileH264High : VAEntrypointEncSlice
VAProfileH264High : VAEntrypointEncSliceLP
VAProfileJPEGBaseline : VAEntrypointEncPicture
VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice
VAProfileH264ConstrainedBaseline: VAEntrypointEncSliceLP
VAProfileHEVCMain : VAEntrypointEncSlice
in my case, my intel cpu does have mjpeg encoding support.
if you can't find anything resembles mjpeg, then, you can pretty much give up the idea of using intel's hardware acceleration to accomplish what you want on that machine.
The next thing you need is to find out rather your ffmpeg binary support Intel's vaapi at the first place. First is to type:
ffmpeg -hide_banner -hwaccels
if one of those line has "vaapi," then, it means the ffmpeg compiled with Intel's hardware acceleration library. If your vainfo command has what you want but the above command doesn't display vaapi, then, you need to get another copy of ffmpeg binary. either from a different source, or compile it on your own.
Next, is to list all the ffmpeg encoder that actually uses vaapi, and hoping one of them resembles mjpeg:
ffmpeg -hide_banner -encoders|grep -i vaapi
In my case, I do have it:
V....D h264_vaapi H.264/AVC (VAAPI) (codec h264)
V....D hevc_vaapi H.265/HEVC (VAAPI) (codec hevc)
V....D mjpeg_vaapi MJPEG (VAAPI) (codec mjpeg)
V....D mpeg2_vaapi MPEG-2 (VAAPI) (codec mpeg2video)
V....D vp8_vaapi VP8 (VAAPI) (codec vp8)
V....D vp9_vaapi VP9 (VAAPI) (codec vp9)
So, in my case, the encoder is there.
if both vainfo and ffmpeg -hwaccels yield what you need but this last step doesn't, then, you need to get another ffmpeg binary from somewhere.
good luck.
Im trying to process a file and run the following command
ffmpeg -i input.webm output.webm
I'm doing it with the ffmpeg library from videoconverter.js. I'm trying to understand what is wrong or how I can fix it.
I end up getting this:

Your ffmpeg build is using version 2.2.1 which is old and unsupported.
It is too old to natively support Opus decoding (this version requires libopus to decode Opus). Upgrade to a build derived from the development branch ("git master") or at least use the latest release.
You should also use a modern libvpx if possible as well. Note that with recent FFmpeg you will need to remove --disable-bsfs because VP9 is now the default video encoder for Webm and it requires the vp9_superframe bitstream filter (it is automatically applied). Alternatively, you can force VP8 encoding with -c:v libvpx.
Consider adding libopus (preferred) or libvorbis support for Webm; otherwise you'll be using the very crappy and experimental FFmpeg native Vorbis encoder.
Ok, did the standard hoembrew install for ffmpeg.
All looks cool, i'm guessing that has to include the mpeg codec, yet I keep getting a 0 byte file and the error message:
