You should look into the concat demux and concat protocol that was added in ffmpeg 1.1. Assuming the codecs are the same you create a file (example mylist.txt): file ‘/path/here/file1.avi’ file ‘/path/here/file2.avi’ file ‘/path/here/file3.avi’ Then pass that file to ffmpeg ffmpeg -f concat -i mylist.txt -c copy video_draft.avi You can use this command to make … Read more

protocol_whitelist is a parameter only on the input file (in your case, MIE.m3u8), so it must be specified before the input in your command. Specify -protocol_whitelist file,http,https,tcp,tls prior to -i and it’ll work as you expect: ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto -i MIE.m3u8 -c copy -bsf:a aac_adtstoasc MIE.mp4 You can a similar case on a Debian Bugs … Read more
I used to do a lot of this stuff when i worked in the industry, I used mencoder personally (which I then wrapped into a VB.NET app to poll the directory for new files and auto encode them when they were delivered) but FFMPEG is the most popular. MP4 and MOV are just containers that … Read more
Seems like faststart support has been included in ffmpeg. FFmpeg Formats Documentation: -movflags faststart Run a second pass moving the moov atom on top of the file. This operation can take a while, and will not work in various situations such as fragmented output, thus it is not enabled by default.
Use ffprobe Example 1: With keys / variable names ffprobe -v error -show_entries stream=width,height -of default=noprint_wrappers=1 input.mp4 width=1280 height=720 Example 2: Just width x height ffprobe -v error -select_streams v -show_entries stream=width,height -of csv=p=0:s=x input.m4v 1280×720 Example 3: JSON ffprobe -v error -select_streams v -show_entries stream=width,height -of json input.mkv { “programs”: [ ], “streams”: [ … Read more
