Wired Out of memory : Java heap space error with ffmpeg library
23 mai 2019, par steve moretzWell this is the error I get:
Out of memory: Java heap space. Please assign more memory to Gradle in the project's gradle.properties file. For example, the following line, in the gradle.properties file, sets the maximum Java heap size to 1,024 MB: org.gradle.jvmargs=-Xmx1024mand it is because of:
implementation 'nl.bravobit:android-ffmpeg:1.1.7'when I remove that the error gets gone.Well the error is saying increase the heap size to 1024MB and I did increase it to 10GB it's not still working.That's what is wired.
org.gradle.jvmargs=-Xmx10000mstill getting the same error.also tried this:
still no chance.Please do not suggest to use an alternative library because I can't.

lame mp3 change bitrate cpp
23 mai 2019, par user2018761I need to change mp3 bitrate, I'm using lame for cpp project under Windows and Linux. I think I need to convert mp3 to wav and then wav to mp3 with desired bitrate.
For wav to mp3 I already have the code (using lame) it works.
For mp3 to wav there is problem with app crashing on hip_decode.
Probably due to ID3 tags at the beginning of the file.
How to skip the ID3 tags or is this a different problem?This is code I'm using
bool Helper::convert2Wav(QString fromFile, QString toFile) { int read, write; int ctn = 0; FILE *mp3_in =fopen(fromFile.toLocal8Bit().data(),"rb"); //this should be WAV FILE *pcm_out =fopen(toFile.toLocal8Bit().data(),"wb"); const int PCM_SIZE = 4096; const int MP3_SIZE = 4096; short int pcm_buffer[PCM_SIZE*2]; short int pcm_buffer1[PCM_SIZE]; short int pcm_buffer2[PCM_SIZE]; unsigned char mp3_buffer[MP3_SIZE]; memset(pcm_buffer, 0, sizeof(pcm_buffer)); memset(pcm_buffer1, 0, sizeof(pcm_buffer1)); memset(pcm_buffer2, 0, sizeof(pcm_buffer2)); memset(mp3_buffer, 0, sizeof(mp3_buffer)); lame_t lame = lame_init(); hip_t l = hip_decode_init(); lame_set_in_samplerate(lame, 44100); //lame_set_VBR(lame, vbr_default); //lame_set_mode(lame, MONO); lame_init_params(lame); qDebug()<<"start decoding"; do { ctn += 4096; qDebug()<<"a message:"</read = hip_decode(l, mp3_buffer, MP3_SIZE, pcm_buffer1,pcm_buffer2); //memcpy(pcm_buffer, pcm_buffer1, sizeof(pcm_buffer1)); //memcpy(&pcm_buffer[PCM_SIZE], pcm_buffer2, sizeof(pcm_buffer2)); //write = lame_encode_buffer_interleaved(lame, pcm_buffer, read,mp3_buffer, MP3_SIZE); //fwrite(pcm_buffer, 1, sizeof(pcm_buffer), pcm_out); } while (read != 0); hip_decode_exit(l); lame_close(lame); fclose(pcm_out); fclose(mp3_in); return true; }It is crashing with an output:

How to combine two ffmpeg commands - adding blur bar and adding logo and subtitle ?
23 mai 2019, par Wai GyiI run the following two ffmpeg command lines to create videos with blur bar, logo and subtitle.
Adding blur bars
ffmpeg -i input.mkv -lavfi "[0:v]scale=iw:iw*3/4,boxblur=luma_radius=min(h\,w)/40:luma_power=3:chroma_radius=min(cw\,ch)/40:chroma_power=1[bg];[bg][0:v]overlay=(W-w)/2:(H-h)/2,setsar=1,crop=h=iw*3/4" blur_bar_added.mkvAdding logo and subtitle
ffmpeg -i blur_bar_added.mkv -i logo.png -filter_complex "[1][0]scale2ref=iw*0.15:ow/mdar[wm][v];[v][wm]overlay=W-w-5:5,ass=input.ass" output.mkv
I would like to know how to combine them to run once. Thanks in advance.
