It's a live FLV stream, Avidemux wouldn't allow me to save it as FLV, saying it only supports FLV1 and VP6.
Is there any tool like Avidemux (my most favorite and trusted tool) that allows me to demux/edit H264 file above in a FLV container? (The reason for asking for FLV container is because the source file is in FLV container and FLVExtract.exe can only extract from FLV container. (I need to use FLVExtract to extract the FLV live stream and then using MP4Box to process the H264, to make the video smooth).
Thanks.

Thanks poisondeathray .
For normal videos (FLV, H264, MP4), Avidemux can handles them 100% with no whatsoever problems and I could save them in any container....but for "Live" streams in H.264, Avidemux either would crash or the saved videos in mp4 or any formats would be choppy/jerky and not smooth at all, and that's the exact reason why I need to first run the H.264 thru FLVExtract.exe and put the H.264 thru MP4Box (mp4box.exe -add "P:\H.264" "P:\New.mp4") and then use Avidemux to edit it to get a perfect video.
For the above video, MP4Box couldn't handle it, see Pix attached. -
Use a 2.6 nightly build. Handles h.264 much better than 2.5.x and below

still no go with Avidemux 2.6 nightly......I'm guessing the problem could very well be due to "live" streaming and my catcher is downloading it at extreme high speed (66.667 FPS ans at times 1000 FPS) while the actual FPS is somewhere between 12 -25 FPS.
In the past:
- WMV problem, run it thru AsfBin and 99% of the time, everything would be OK.
- MKV problem, run it thru MKVtoolnix and 99% of the time, everything would be OK
Is there any tool now to run this H.264 in FLV container and hopefully the correct time stamps/FPS would be inserted?
x264.exe --output NUL C:\input.avs x264 --output /dev/null ~/input.y4m
x264.exe --output NUL --fps 25 --input-res 1280x720 D:\input.yuv x264 --output /dev/null --fps 30000/1001 --input-res 640x480 ~/input.yuv
Can the above from https://www.videohelp.com/tools/x264-Encoder help?
If my H264.flv is in P:\H264.flv, how would I go to force it to make the FPS to 20? -
If you re-wrap elementary stream, a normal elementary video will take on the new FPS that you enter. So if you used mkvmerge or mp4box for example
But there might be errors in your stream
If my H264.flv is in P:\H264.flv, how would I go to force it to make the FPS to 20?
Otherwise you can try re-writing info in the stream with a patched FFmpeg build. See this:

Probably something is wrong with your video, or else mp4box wouldn't have problems
Try mkvtoolnix, instead of your regular mp4box procedure. Load video (might have to demux first with flvextract), highlight the video track, format specific options tab enter the fps, push start muxing -
Brilliant idea and I'm getting somewhere now...
1) Using FLVExtract.exe to get the H264
2) Run thru Mkvtoolnix and highlight the video track, format specific options tab enter the FPS "20"
3) Use Avidemux 2.6 to edit (Yes, only 2.6 would allow me to edit (cut/delete), Avidemux 2.5 wouldn't move at all (the slider)
4) End result is good (Frame rate is staying at 20FPS)
Now with Avidemux, I'm trying to stay with 2.5 nightly cause it allows me to change Frame rate with just one click, under Video Tab and the Frame rate would stay. Avidemux 2.6 nightly somehow going backwards, with Frame Rate now buried under filters (at least 6 clicks more than 2.5 nightly) and the Frame rate wouldn't stay even after I entered 20 at "Change FPS" and "Resample FPS" (see info below) and one more thing about 2.6 nightly, there is no option to disable audio? Avidemux 2.5, I can simply click Audio Tab and select "None", or am I missing something?

This is using Avidemux 2.6 nightly, even after changing the frame rate to 20 at both "Change FPS" and "Resample FPS", it's still not sticking at 20FPS, it's still way too fast!
P/s, Will there be any potential conflicts by installing both 2.5 nightly and 2.6 nightly? and is the Win64 versions less stable than the Win32 versions?Last edited by tigerb; 9th Dec 2011 at 00:57.
