How can I use heroku-22 stack without error ?
What can I do ?

FFmpeg conversion to Photo-JPEG is blocky [duplicate]
26 mai 2017, par Richard210363This question already has an answer here :
I am converting .mp4 files to .mov with the Photo-JPEG codec to use in After Effects to reduce render times.
I have looked up the FFmpeg commands to do this and come up with :
ffmpeg -i tower-bridge.mp4 -an -pix_fmt yuvj420p -vcodec mjpeg -f mov -y tower-bridge.mov
This works but when I look at the output video it is quite blocky ; like a mosaic.
During the conversion I get this message :
[swscaler @ 0000000008c97fe0] deprecated pixel format used, make sure you did set range correctly
Research on-line suggests I can ignore this message.
What can I do to improve the output quality ?

How to force specific AVInputFormat in code (FFMPEG) ?
18 février 2020, par kugipark++Plaease understand that maybe some words or sentences could not be correct English.++
I’m novice programmer and developing a video player app for Android which can play 5ch .avi video from http. It based on ffplay.c in FFMPEG libarary.
Currently I have 2 problems for this below. It has occured only in android devices.
1) Too much time taken for detecting format.
- opening and finding stream info takes more than a minute when I trying to open 5ch video source whereas normal .mp4 (h264) source open almost immediately.
2) Demuxing is too slow when it comes to large size video.
- If the resolution of video getting larger, then displaying frame rate getting slower even though there are enough memory, network and CPU resources physically.
To resolve my problem, I tried to force the format and decoders but I couldn’t found some information for specifying the input source in code level.
The official doc site only refers to a sentence about those parameters like "If non-NULL, this parameter forces a specific input format. Otherwise the format is autodetected.". So I don’t have any clues how to set the number of streams, decoders, decoders’ private options, and etc. (And also which parameters should I manage.) If someone knows how to set the options(like AVDictionary), and pass to the av functions, please let me know an exmple. The source contains 2 video streams, 1 audio stream, and 2 more extra streams (for custom data like gps). The stream information of video is below. I printed it manually, and these are auto-detected information.---------- File format information ----------
