For example this command:

Error opening output files: Invalid argument(response0.png is the first downloaded segment from hls)
I think that "Stream #0:0: Video: png ..." means that this file is in png format, and it does not have audio track. But it has audio track, because I can play it.
Probably segments are in some non-standard format, but how to find out what format is it?

How to Install ffmpeg on aws lambda machine ?
25 avril, par Martin BlausteinI'm trying to run a node js script on AWS lambda that uses ffmpeg. To do this, I need to install ffmpeg on the machine itself.
I have looked through the documentation but I could not find how to connect to the machine that runs the lambda.

Remove Rotate metadata from mp4
25 avril, par mbajurI'm trying to remove or modify a
rotateparam from my mp4 file using ffmpeg. Based on some google results, i've ended up with such command (i've tried a few more but none of them worked):$ ffmpeg -i ./source.mp4 -metadata rotate=0 ./output.mp4But it's not working at all. The
rotate=270metadata param is still there in the output file. Can you please advise me on how it should be done?I'm using

Converting DAV to MP4 and OGG
25 avril, par mackowiakpI want to prepare WEB page containing films from security camera recorders. Each recorder transmit video files in DAV format so each film is converted to MP4 format by script, using such syntax:
ffmpeg -y -i movie.dav -vcodec libx264 -crf 24 movie.mp4So I included in HTMLv5 code such entry:
It works correctly with Chrome but not with Firefox. For proper work in FF it is necessary add link to OGG file. So correct HTMLv5 syntax for both browsers should look like this:
Can anybody help me to pass correct ffmpeg syntax to create OGG file?

How to cleanup data to reuse ffmpeg.wasm instance
24 avril, par rickyzI have multiple files that I am trying to process back to back using ffmpeg.wasm. I have noticed that after around ~150 runs, a memory issue comes up:
RuntimeError: memory access out of bounds. I tried doing cleanup usingffmpeg.deleteFile()on both the input and output files after every run, but that didn't make a difference. Is there something I am missing that will allow me to reuse the ffmpeg instance as many times as I want?If I can avoid it, I do not want to have to call
ffmpeg.terminate()after each use since loading ffmpeg for the next use takes a long time (~.5 secs on my test machine).Note: I am using the updated ffmpeg.wasm v0.12+ in a browser setting
