You can list all available ones using the configure option 'list-indevs'. When you configure your FFmpeg build, all the supported input devices are enabled by default. x264 will be of modest use if you keep to strict lossless mode. Input devices are configured elements in FFmpeg which enable accessing the data coming from a multimedia device attached to your system. I would like to know if there are any ffmpeg settings that have an effect on the JPEG encoding (I already tried a few but no success) or whether there is an older version of ffmpeg which encodes differently. ffmpeg video-conversion mpeg4 mjpeg Share Follow asked at 13:52 lpacheco 675 5 9 22 Add a comment 1 Answer Sorted by: 11 Your command will do it but the chief draw of x264 is the ability to provide high compression while maintaining subjective visual transparency. Has anyone experienced similar problems? It seems somehow ffmpeg is creating incompatible MJPEG content. I see differences between a file which works and which doesn't but that's it. I also tried to examine the headers using this website but without knowing the exact specifications of the hardware decoder I don't know what to look for. I have not been able to find export settings in GIMP which make the decoding fail. FFmpeg-trac 10296(undetermined:new): ffmpeg is not aware of the attribute x-dimensions when ingesting an MJPEG RTSP stream FFmpeg trac at Fri Mar 31 14:04:55 EEST 2023. If I load the same image in GIMP (image editing software) and save it then I can decode the image just fine. If I split the content into seperate frames (in MJPEG each frame is standard JPEG image) the 'X170 JPEG Decoder' tools says 'JPEGDEC_UNSUPPORTED'. support MJPEG as some Foscams no longer do then you can set mjpegUrl to contain ffmpeg to use your CPU to generate a MJPEG stream Title Foscam IPCamera. The hardware decoder gives an error saying the stream is not supported. I have video content in MJPEG format which I try to decode.
