JavaCV FFmpegFrameRecorder not saving / writing to disk
23 juillet 2013, par Israel LopezI'm using JavaCV libraries on Android, and I've been able to get the sample Recording activity working somewhat, however it is not writing to disk on my SD card.
Code : https://gist.github.com/ilopez/6046287
Log : https://gist.github.com/ilopez/6046289
Manifest : https://gist.github.com/ilopez/6046296Unlike save video using ffmpegframerecorder android question, there is no fatal exception. Just nothing is written to the sdcard.
I have tried the following filenames
/mnt/sdcard/test.flv - no IO Exception
/sdcard/test.flv - no IO Exception
/idontexist/sdcard/test.flv - IO ExceptionI have also tried to place a file in the sdcard folder, nothing saved.
I am confirming the files existence by hooking it up to my computer and viewing the SCH-I535/Card directory.
I also modified the source a bit per my previous question : How to convert ShortBuffer to Buffer[] ?

ffmpeg record screen and save video file to disk as .mpg
7 janvier 2015, par musimbateI want to record the screen of my pc (using gdigrab on my windows machine) and store the saved video file on my disk as an mp4 or mpg file .I have found an example piece of code that grabs the screen and shows it in an SDL window here :http://xwk.iteye.com/blog/2125720 (The code is on the bottom of the page and has an english version) and the ffmpeg muxing example https://ffmpeg.org/doxygen/trunk/muxing_8c-source.html seems to be able to help encode audio and video into a desired output video file.
I have tried to combine these two by having a format context for grabbing the screen (AVFormatContext *pFormatCtx ; in my code ) and a separate format context to write the desired video file (AVFormatContext *outFormatContextEncoded ;).Within the loop to read packets from the input stream( screen grab stream) I directly encode write packets to the output file as shown in my code.I have kept the SDL code so I can see what I am recording.Below is my code with my modified write_video_frame() function .
The code builds OK but the output video can’t be played by vlc. When I run the command
ffmpeg -i filename.mpgI get this output
[mpeg @ 003fed20] probed stream 0 failed
[mpeg @ 003fed20] Stream #0: not enough frames to estimate rate; consider increasing probesize
[mpeg @ 003fed20] Could not find codec parameters for stream 0 (Video: none): unknown codec
Consider increasing the value for the 'analyzeduration' and 'probesize' options
karamage.mpg: could not find codec parameters
Input #0, mpeg, from 'karamage.mpg':

At least one output file must be specifiedAm I doing something wrong here ? I am new to ffmpeg and any guidance on this is highly appreciated.Thank you for your time.
