![]() ![]() I'm thinking of learning everything about the MPEG or MPEG-2 language, just so I can see first hand how it works. I wouldn't really do this for all my movies, but I'm just deadly curious, you have no idea how curious about this. or would it be the same as if you did it all in one go.? Would it look far worse if you first resized it to 700x449, then 699x449 etc. Would I do better to convert it to the exact, native resolution of my tv and do a double-pass on it or would it not matter?Īnd suppose you had a 700x450 image, and you wanted to resize it down to 320x200. ![]() Is it calculated or could it possibly be done electronically (non-binary system used to blend/get the average values) or could it possibly be done optically as in mirrors/prism-style type of blending of lights? There obviously has to be something done to meld or blend the images.Īnd my next question is this: Suppose I have a 700x450 movie (or any movie that's not exactly the resolution of my tv). Easiest way to resolve the low resolution of reverse camera is changing a LED. Also, I suspect that if I ran ffmpeg commands in quick succession it could lead to stuttering the video being played - because ffmpeg could clean up chunks that were not played back yet, but ffmpeg considered them old.Why is it so easy to resize the entire thing/change the entire resolution on the fly with very limited cpu/memory resources?Īs an example, my creative zen vision m is limited to about 2-3mbps video (depending on the type of codec), but has no problem at all scaling to the exact required amount that's needed for either its screen or its output to my 576 line pal tv. 140-degree lens records 1080p video, Live View for remote monitoring. Of course, I still have to make sure that I have the next video ready when the current video playback comes to an end. The player picks everything up automatically. When ffmpeg command finishes, I just have to re-run it with the video I want to go next. The result is the infinite video that I can play with ffplay out.m3u8. I also changed the default number of chunks in the playlist to 30 with -hls_list_size 30 flag. To prevent that, and also to make sure that ffmpeg cleanups and does not override the existing playlist, I added these flags: -hls_flags delete_segments+append_list+omit_endlist. By default, ffmpeg adds a terminating command to the m3u8 file. It makes ffmpeg take the input video, split it in chunks, save them and generate a playlist for HLS consumer (ffplay in my case).īut I want to make sure that the playlist is infinite. 1 Answer Sorted by: 3 The normal way to achieve something like that is to encode the video using an adaptive bitrate format. To make this work, I added -f hls flag to the ffmpeg command. Click the 'More' button next to 'Video Scale Size' twice to input a custom video ratio. Choose 'MP4' for the Output Container and 'HD'. And then drag the target file into the timeline. The player does not need to know beforehand how many chunks there are and which will be next - these were exactly my requirements. Download and install a change video resolution software, and we recommend using EaseUS Video Editor. In a nutshell, it's pretty simple - it just lists chunks of video and their duration in a text file, so that player knew which chunk to play next. HTTP Live Streaming is a protocol implemented by Apple. I've managed to get what I want with the following command (by following Ryan Williams's tip to use HLS): ffmpeg -i source.mp4 -s 640x360 -hls_list_size 30 -hls_flags delete_segments+append_list+omit_endlist -f hls out.m3u8 I hope you'll be able to get me into the right direction. I'm really new to ffmpeg, so I'm sorry if I'm asking for something obvious or impossible. ffplay should automatically and seamlessly start playing it, but only after it finished with the first file ffplay should automatically start playing it ![]() If I run the same ffmpeg command again, ffplay plays the video from the start with ugly artifacts. ![]() I tried to append to a file and just play it with ffplay like this: ffmpeg -re -i source.mp4 -f mpegts - > video.tsīut that didn't work - once ffmpeg is done with the file, ffplay stops playing. When one video is finished, the next one should be played seamlessly, without any delay. I'm going to playback videos with ffplay. but usually refers to re - generating the fonts on the fly each time they are. This should work locally, without any networking. font page A portion of video memory reserved for holding. I want to show videos non-stop without knowing beforehand which videofile would go next on a Linux host. ![]()
