[FFmpeg-user] Set timeout with linux named pipe
Hi, My command is below. ffmpeg -y -thread_queue_size 128 -use_wallclock_as_timestamps 1 -f h264 -i test/15210660145/2/vback -thread_queue_size 128 -use_wallclock_as_timestamps 1 -f g726 -ar 8000 -i test/15210660145/2/aback -acodec aac -vcodec copy -f flv rtmp://127.0.0.1:8080/myapp/15210660145_2_back. The intput is test/15210660145/2/vback and test/15210660145/2/aback ,both files are linux named pipe.Now I want to termnial the command when the input has not data come. I have tried -stimeout and -timeout it seems not the correct way.

[FFmpeg-user] trouble shooting defective FFmpeg install on Windows 10?
Hello: What would you suggest I do to troubleshoot a defective install of FFmpeg for Audacity on Windows 10? A colleague installed FFmpeg for Audacity 2.2.2 on a Windows 10 computer. Edit > Preferences > Libraries > "FFmpeg Library:" = "C:\Program Files (x86)\FFmpeg for Audacity\avformat-55.dll". When we did File > Open (or Import) > [a *.MOV file], we got a message saying FFmpeg for Audacity was required. But we have it. I'm not sure, but I believe we installed it following the instructions on "https://manual.audacityteam.org/man/installing_and_updating_audacity_on_windows.html#winff;. Thanks, Spencer Graves p.s. A week ago I installed FFmpeg for Audacity successfully for computers running Windows 7 and 10 and for macOS 10.14.6. Now I try what I think was the same procedure on a friend's Windows 10, and it fails. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

[FFmpeg-user] Listing the hardware accelerators
Hi List, I have different environments (X86, ARM, Jetson Nano) on which I'd like to use hardware encoders and decoders if available. I guess that I won't be able to use them if they have not been built in the ffmpeg dependencies if I install a "generic" version. Will the configure command autodetect what it should build, or do I have to know my hardware before launching configure with specific options? I have read https://trac.ffmpeg.org/wiki/HWAccelIntro but it's not clear to me yet. Is there any way to have ffmpeg list what it has "found" on my system? Do I have to launch a series of commands with the different accelerators that exist, and see the output? I suppose we have to specify on the command line the hardware acceleration chosen for the ffmpeg command, it won't autodetect and choose one that is available, am I right?

Most likely, ffv1 was created with high compression in mind, not necessarily with high playback speed. Note that j2k decoding is typically similar demanding (although j2k allows faster low-quality decoding). GPU is not used. > Or is there something I can do to play it smoothly?

I suspect it is something about the palette generated. I have been using palettegen and paletteuse filters lately, and they have worked out fine for me. This command is working as you might expect: ffmpeg -y -i sidereal.gif -filter_complex "split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" sidereal2.gif (2.8M) In fact, limiting the number of colors to 128, makes the file smaller: ffmpeg -i sidereal.gif -filter_complex "split[s0][s1];[s0]palettegen=max_colors=24[p];[s1][p]paletteuse" sidereal2.1.gif (2.2M) Hope it helps!
