Transcoding Mp4 video on Android with FFMPEG
18 octobre 2012, par geeknizerI've compiled FFMPEG binary from Bambuser project (refer question) and have pushed binary and .so files to application directory.
But when I try running FFMPEG with input file, it always complains file not found.

Replicate the format of a video to another
10 octobre 2017, par BasjLet’s say I have :
-
video1.aviwhich is perfectly played (both sound and image) on my TV’s USB media input -
video2.aviwhich is not recognized by the TV : "Imposible to read this format"
I have tried lots of solutions, like :
ffmpeg -i video2.avi -codec:a libmp3lame -q:a 0 -ac 2 -ar 48000 -joint_stereo 0^
-codec:v libxvid -q:v 25 video2_reencoded.aviand when I compare
video1.aviwithvideo2_reencoded.aviwith MediaInfo, they look similar in most aspects, but finally the TV won’t playvideo2_reencoded.avi.Is there a way with
ffmpeg, to replicate all the specifications ofvideo1.avi(sound encoding properties, video encoding properties, image size, container type, etc.) onvideo2.avi?
Appendix : output of MediaInfo for the three videos. In this specific example,
video2.aviandvideo2_reencoded.aviare half-working : image ok but not the sound. In other video examples I tried,video2.aviandvideo2_reencoded.aviwould be both totally "Impossible to read".video1.avi(i.e. working)Format : AVI

FFmpeg on Azure Function call running slowly and producing an empty output file
7 novembre 2017, par The LemonI’m trying to make a function which uses ffmpeg, so far I haven’t been able to get anything other than the -version command to work properly. When I try to run a simple
ffmpeg -i {input file path} {output file path}command, the function seems to get stuck for 3-4 minutes (in the process creating an empty output file), then try again and produce the error ’file already exists’. I’ve tried switching between the 64 bit ffmpeg.exe and the 32 bit ffmpeg.exe with the function running as both a 32 and 64 bit function. My code and the associated logs from trying to run the code are included below, if anyone can tell me what I’m doing wrong or how to get the process to work it would be greatly appreciated. Thanks in advance, Cuanedit : The process works on kudu with the same files, the output is shown at the bottom. On kudu the process ran in under half a minute, clearly something is causing the function process to hang, if anyone has advice it would be greatly appreciated. Thanks again, Cuan.
second edit : I tried adding the -y to the end of my command, this works in that it no longer complains about overwriting, but alas it now just hangs twice due to timeout. (output at the bottom)
edit the third : azure has a way to let you run functions locally, my function ran into the same issues on the local version but : as it turns out the actual processing is done within a few seconds, it just takes forever to decide to write to a file - if you terminate the process manually after the process had been running for 10 seconds the file immediately gets written. Again, any help is appreciated. Cuan.
